Everything You Need To Know About Magnetic Particle Testing

Everything You Need To Know About Magnetic Particle Testing

Magnetic Particle Testing (MPT) is a method used to detect surface and near-surface flaws in various ferromagnetic materials. It is primarily used for detection of cracks. The specimen is magnetised either locally or overall. If, anyhow there is a flaw, the magnetic field gets distorted, causing leakage in the local magnetic flux. This leakage is displayed by covering the surface with very fine iron particles applied either dry or suspended in a liquid. The particles accumulate at the regions of flux leakage, producing a build-up which can be seen visually even when the crack opening is very narrow. Thus, the crack can be identified as a line of iron powder particles.

The method can be applied on almost all metals which can be strongly magnetized, like ferritic steels and irons. It is a type of inspection process included in the non destructive testing.


The method of magnetisation is to produce a magnetic field with lines of force at a large angle to the expected direction of the cracks. The application of magnetisation can be used more than once in different directions based on the requirement.

The magnetisation is generally produced by any of these following methods:

• Applying a permanent or electro-magnet to the surface (magnetic flow)
• Passing a large current through the specimen by means of current prods (current flow)
• Putting the specimen inside an electrified coil, or forming a coil around the specimen
• Making the specimen a secondary loop of a transformer (suitable for ring-shaped specimens)
• Placing an electrified coil or loop close to the specimen’s surface
• Threading an electrified bar through a hollow specimen.

The application of electricity

The electric current used can be of any waveform from DC to AC. The amount of electricity required to produce adequate magnetisation is dependent on the supply, process and material of the specimen. It is important to ensure that the applied electricity is appropriate for the specimen size and shape and also that the direction of the magnetic flux produced is suitable for the cracks expected.

The process of applying iron particles

Usually the iron particles, dry powder or liquid (magnetic ink) is applied while the magnetising current is still flowing. Residual magnetisation is also used at times, when the particles are applied after magnetisation. Some steels retain sufficient magnetic property for this method to be satisfactory, and in this case smaller, more portable, magnetising equipment can be used.

What is The Relation Between NDT And AICIP?

What is The Relation Between NDT & AICIP-

A set of techniques used in the inspection of a material’s integrity are called NDT (Non-Destructive Testing). These inspection techniques are performed by certified inspectors to avert accidents in working areas of factories. Now a question arises, who certifies these inspectors? Is there a number of certification boards or just one? Are the certifiers working under Australian Government? Let’s find out the answers to all these questions.

What is AICIP?

AICIP (Australian Institute for the Certification of Inspection Personnel) is a non-profit body. This certifying body is incorporated with the Department of Fair Trading under the Associations Incorporation Act 1984. It is an Australian Registered organisation with the Australian Securities Commission. Professionals certified by them are known as AICIP pressure vessel inspectors.

Why were they formed?

Due to Government policies of National Standard for Plant, owners of industries that deal with engineering plants need to ensure that competent persons are hired to inspect such in-service plants. Therefore, AICIP was formed by the organisations of industries, with the support of State Regulatory Authorities. The board was established to provide competency certification programmes for the inspectors.

When were the first AICIP examination held?

The first examination for AICIP was successfully completed on the 10th of July 1997. The examination was held to certify all of the inspection personnel including junior and senior in-service inspectors of Pressure Equipment.

Does AICIP holds training courses or approves private training organisations?

No, AICIP do not conduct any training courses, just to prevent conflict of interest between the inspectors and the training personnel. ACIP, therefore only stands for examining/certifying programs.

What types of plants and inspection personnel are covered by AICIP?

AICIP certifies design verifiers, welding inspectors and other in-service inspectors. The types of plant or equipment covered by AICIP includes pressure vessels, amusement devices, lifts, pipelines, mechanical testing, metallurgical investigation, radiography and ultrasonics.

What does AICIP certification mean to an owner?

It is the owner’s responsibility to ensure that the inspection is performed by a competent
person. AICIP certification means, the owner is establishing safety and productivity in the working ground. AICIP certified inspectors also ensures durability of the mechanism.

Can an owner hire inspectors who have previously inspected the plant?

It is the prerogative of an owner to employ whoever he/she wishes. They must observe appropriate standards and regulations according to the State or Territory in Australia. AICIP offers the owners the opportunity to utilise a nationally recognised, independent certifier to assist them with expert responsibilities.

Thus, whenever you conduct NDT tests, make sure you hire AICIP certified inspectors.

How Do Freight Forwarders Help Personal Shippers & Businesses?

How Do Freight Forwarders Help Personal Shippers & Businesses- (1).jpg

Although there are quite a good number of businesses that do not use professional logistics management solutions, there is no denying of the fact that freight forwarders in UK provide a wide range of benefits to personal shippers & business owners. In Sheffield alone, a majority of people utilise or have used the services of international freight forwarding services. So how exactly do these service providers benefit their patrons? Here are some of the most important ones:


Most companies offering freight forwarding services cater a unique flexibility to meet rigid deadlines and handle unforeseen circumstances such as delays or rerouted shipments with ease. For them, dealing with problems of such nature is just like any other day at work.

Organisation & Management

Due to having a wide network of resourceful associations, freight forwarders are able to ensure fantastic organisation and management of shipments. They can promptly trace back a problem to its root and implement the necessary solutions. Third party companies may not always be so fast and can cause a lot of hassle.

Customs Clearance

There are a number of freight forwarding businesses that have in-house experts to cater effective customs clearance services. They possess comprehensive knowledge about tariffs, paperwork & regulations, and also help to deal with them ideally. As such, partnering up with international shipping agents can make any overseas delivery a breeze.

Door 2 Door

The most important portion of the journey of any cargo is after its delivery to the port. Without a freight forwarder, it can be really difficult to have the good delivered safety to its destination. But a competent logistics management agent can help in making the shipment successful.

Cost Savings

The superior client support, incentive and knowledgeable advice of freight forwarders can spell various financial perks. Initially, storing shipments at some extra warehouse can seem kind of unreasonable. But when long term benefits are considered, it can be very profitable to utilise an additional distribution centre and have more control over the cargo, because it would allow for quicker shipping and give an edge over rival businesses.

Peace of Mind

Last but not the least, people who use professional freight forwarding solutions would agree to the fact that partnering up with shipping experts may the entire supply chain management so much easier. There’s no need to worry about comparing rates, negotiating services or vetting carriers.

Thus, these are the ways that international freight forwarders benefit personal shippers and businesses.

Inspecting Pressure Vessels Or Boilers

Inspecting Pressure Vessels Or Boilers.jpg

Pressure vessels and boilers are all same. Traditionally they used to generate steam. To this day, their duty remains the same in a much more advanced manner. Boilers range in size, and can be anything from coffee machines to large industrial boilers. All of them generate the same heated steam but in a different process, temperature and purpose. Industrial boilers are used to drive heavy turbines for generating electricity.

History of certification
These complex vessels work under extreme pressure because of the rapid expansion of stream, and thus, boilers can be very dangerous. If a boiler explodes the results can be catastrophic. Because of these disastrous effects of exploding boilers, government introduced Boiler Codes in the early 1900s to certify manufacturing and inspection of boilers for safe operation.

After the development of boiler codes, frequency of explosions has reduced in a significant number. However, incidences still happen and they can be seen on news largely due to the failure of maintaining safe work guidelines of boiler codes and standards.

Who does the certification?
The inspection of the boilers begin right from the manufacture process and continue till the complete life cycle. The certification of the components, design, material, and the manufacturing processes of the boilers (many of which are pressure vessels), are conducted by AICIP pressure vessel inspector in Melbourne. Every state and territory both nationally and internationally has to maintain the standards of boiler and its pressure pipe systems for safe operation.

Therefore, the plant owner, international agents of the owners, engineers, operators and even the inspection bodies, all have a specified duty of care and responsibilities to maintain the compliance. Legal consequences including hefty fines and jail terms may have to be faced if the standards are not met properly.

The process of inspection
Inspection of a boiler is very extensive. At first, external inspections are conducted on the boiler when it is live and operating. Any unusual parameter such as leaks, corrosion, vibrations, etc. Leads to immediate decommissioning of the boiler and the key elements and components are stripped off. They are then repaired through a dry inspection.

When the boiler is re-built all the operation and safety devices are tested at maximum operating pressures including flame (direction, quality and colour), water treatments, low water alarms, pressure reduction devices and safety valves. If all the tests are passed only then the boiler is deemed to be safe and a certificate is issued.

At the end of the day, inspecting a boiler means a lot to every industry. It is not just for safety but also to ensure better productivity.

Defining Acrylic In An Easy Way

Defining Acrylic In An Easy Way

Acrylic, whose chemical name is polymethyl methacrylate is a transparent thermoplastic, which is used for a variety of applications especially for making signs, displays and other daily utility goods.

Acrylic is a shock-proof and light-weight material which is a good alternative to glass and enjoys better durability than the former. Acrylic fabrication is a process that provides different shapes to acrylic plastic with the help of modern technologies and is used by expert professionals.

The process involves certain methods like compounding, extrusion, lamination, welding, foaming, vacuum foaming, etc.

How an acrylic is fabricated?

As it is a fabrication friendly product, acrylic can successfully withstand cutting, machining, and bending that helps to achieve a desired shape and structure. The first step of fabrication involves creating a mould with the required form and shape in which the molten acrylic will be poured. Because of its intrinsic thermoplastic properties, acrylic becomes flexible when heated which allows to take any shape of any contour.

Different tools are used in the process in order to achieve enticing acrylic patterns to fulfill specific needs of clients and industries. Some of the tools are: lathe for cutting sheets, milling machine for moving the sheets, polishing machines to provide beautiful glossy finish to the plastic and at last the annealing machine to distress the plastic.

Types of Acrylic Fabrication

There are different types of methods applied on an unprocessed acrylic to create desirable shapes and structures.

Acrylic sheets are cut with the help of acrylic-cutting blades, saber saws, plastic cutter, routers or table saws. The sheets are applied with a flame-polish for glossy finishing at the edges with using hydrogen-oxygen torch.

Acrylic fabrication also includes rendering different colours and decorations to the materials with the help of screen-printing, spray painting and decorative vinyl films.

Applications of acrylic objects

For its huge range of benefits, acrylic is mostly used business owners who are looking to establish a successful marketing campaign. Thus, acrylic objects are common in exhibitions and as display solutions in the form of decorative items, signage, light fixtures, and purchase displays. Apart from these major applications, acrylic is also used for making:

• Lenses
• Aquariums
• Windows
• Police shields
• Architectural glazing
• Submarine windows
• Rear projection screens

Having excellent optical clarity and resistance ability, acrylic fabrication in Sydney has made itself apt for several domestic, industrial and commercial applications.

Today courier services are focused on the flexibility in terms of real-time parcel tracking and more accurate deliveries, converting their services into highly convenient mode of transportation. Moreover, their experience in the industry and range of options matter a lot for the customers.

Couriers By Land

International shipping agents employ varied modes of transport to get a courier from point A to B, and the type of vehicles used generally depend on the kind of package you are shipping. Dedicated vans and two wheeler couriers can handle the most urgent same day deliveries. They ensure that your package is delivered in the shortest time limit possible. However, in the case of long distance deliveries larger vehicles like trucks may need to be used.

For special items, good couriers can provide vans with additional strapping and storage facility so that your packages are contained safely during transition. The drivers too have expert knowledge on loading and unloading and this ensures safe arrival of your goods in the best condition as you sent them.

Couriers By Air

There are businesses which require international deliveries. Companies that are doing deals overseas or whose business relies on the quick delivery of products need couriers who can not only collect quickly, but have the ability to allow speedy delivery in the destination country. This means by using dedicated courier and freight flights, you can ensure high standard delivery to your clients. This is particularly true if you need to handle delicate goods or fine-tuned medical or technical equipment.
The courier industry is growing exponentially at the moment with exciting developments in the field of technology. This can directly improve the range of services to a customer.

How Acrylic Displays Can Revamp Your Business

How Acrylic Displays Can Revamp Your Business%00.jpg

Gone are the days when business owners used to prefer metal and wood displays for promotional purposes. Today, modern business men and women look for a more effective way of promotion. This is why they prefer acrylic displays for their business. Acrylic displays provide excellent marketing advantages a lot more than traditional promoting options. The unique plastic has brought a revolutionary change in the field of promotion with a number of benefits which include:


Acrylic displays in Sydney are the primary material of promotion. Due to the strength provided by the incredible plastic, you can easily utilise it to manufacture both small and large signage of different weights. This means it is durable and lasts for a longer period.


One of the unique features of acrylic sheets is their ability to form into different shapes. Due to this feature, the sheets can be moulded and customised into different products like racks, wall mounts, cases, stand holders, etc. It is up to you, which one you choose to use, as customised items are always the best. Since acrylics are water proof, you can also use them in both indoor and outdoor applications.


While acrylics are available in different colours, most of them are transparent. This allows the customers to understand properly what you are displaying and how it/they will benefit them. This often translates to increased sales. In addition, acrylics are lighter and thus you can carry the displays wherever you want. Portable acrylic displays are a good idea when you are promoting newly launched items at various places.

Ease of cleaning

To make the displays more attractive, you must clean them on a regular basis. Acrylic displays are easy to clean and do not require much effort. All you need is a moist cloth, some water and liquid soap. While cleaning, make sure that you do not use harmful chemicals as it can ruin the quality of the material and discolour it.


If you are in the market for quite a long time, you must know that the traditional promoting materials are not as cost effective as acrylic displays. Today, marketing has become a lot easier because acrylics are very cost effective. This lowers the investment in marketing campaign of a business.

However, to enjoy all these benefits of acrylic displays, it is recommended that you buy them from a reputed manufacturer and supplier.

The Importance Of Warehousing

The Importance Of Warehousing.jpg

Warehousing is an important aspect of imports and exports. Business owners often need extraordinary warehousing and distribution solutions. Some of the people view the process of warehousing as useless, and simply wastage time before the delivery. Well, to prove this wrong here are some benefits of warehousing from the freight forwarding services in Sheffield.

Central location

A warehouse is the central location where all the shipments are received and stored before distribution. When a shipment arrives, the goods are transferred to the warehouse personnel. Then they are identified, sorted and further dispatched to their specific temporary storage locations. Storage is not meant to hold the products unnecessarily, but it is a process that includes specialised maintenance and security measures. It also provides an environment to the goods that preserves the integrity and usefulness.

Value added operation

The advanced process of warehousing delivers high quality storage that matters a lot for the shipment. It lowers the shipment costs and improves customer service. Warehousing lets the goods increase their utility value by ensuring dispatch of the right product/s to the right place at the right time. Moreover, operations like assembling, consolidation, cross-docking, etc. are all done in a warehouse.

Economic Benefits

Warehousing provides economical benefits through its specialised operation and storage capacity. For example, benefits are gained through accumulation and consolidation works. Consolidation is done to cut outbound and additional costs for both the clients and their customers. Instead of delivering items individually from different sources, they are delivered to the central warehouse. On the contrary, accumulation is done to allow the warehouse act as an accommodation platform for the items. It plays a role of buffer, that balances commercial demand and supply of a product especially for seasonal and long term storage. This is a vital process through which a business profits. For example, if a certain type of product is needed all the year round then they can be stored in the warehouse to increase the demand. When they are released in the market the price automatically shoots up resulting in high profit.

Service Benefits

Warehousing can help you a lot when it comes to contingency plan. It makes sure that all the outbound orders are full within the allocated time. This is called safety blocking to maintain the predetermined number of inventory items.

An experienced freight forwarder can accommodate all your shipments in their warehouse and deliver them as per requirements.

Important Things You Need To Know About Acrylic Signage

Acrylic Signage Sydney.jpg

Plastic is the new revolutionised material on top of metals and woods. And on top of it acrylic is the upgraded version of plastic. We hear a lot about acrylic signage. It plays a vital role in decorating your commercial and residential environments.

There are different types of acrylic signage. Custom made signage is usually designed for business promotions. Another type is the street signage which is used to convey general message or information to pedestrian, and drivers. This shows that acrylic signage in Sydney is the best advertising and informing agent. It can be used for both indoor and outdoor applications. It comes in a variety of colour and thickness options. This adaptable artifact gives you limitless benefits and is also lighter than glass. A recent study on acrylic sheets show that they can remain unaffected for years even if the atmosphere is acidic, or salty. It has been seen that the lucidity, gloss and the shape remains the same.

Background of acrylic signage

Whether it is an acrylic signage or a flex, the background is always made with aluminium box. The illumination is done with the help of fluorescent tubes or LED’s.

So, what are the considerations you need to make before you order a customised signage?

Size – Size makes the difference between a signage and a flex. If the size of the aluminium box is bigger (generally in height) it will be called a flex. On the contrary, smaller boxes are referred to as acrylic signage.

Design – The exterior design or the colour totally depends upon your preferences and needs. But the interior of a signage must be selected with caution. If the design is purely based on texts or graphics, then vinyl would be the best option. On the contrary, if you would like to print the same directly on the acrylic sheet make sure that the density of the ink is thick so that it can be seen after illumination.

Aesthetics – If the width of a signage is more than 3 meters then it needs to be joined. The issue arises from here. The place of the joint often becomes a problem. This can be avoided if you consult it with a plastic fabricator in Sydney.

Therefore, these are the basic considerations of an acrylic signage if you plan to go for a customised version of advertisements for your business or simple decorations. The smooth and sleek surface of the acrylic signage proves to be very inviting almost like a glassy ocean.
