What is the destructive testing of metals and why is it important? The high specification materials that Special Piping Materials supplies to clients around the world is subject to rigorous testing to ensure that they can perform in high-stress environments. Let’s explore what destructive testing is and how some of the tests are carried out.
Corrosion, heat and pressure are all things that some of Special Piping Materials products will have to endure. Subsequently, whole systems can be reliant on the metal that the products are manufactured from in the first place.
With this is mind, it becomes obvious as to why destructive testing is so important. It is needed to ensure that our range of products, such as round bar, forged fittings and seamless pipe, perform in the way that they are required to.
All stock held by Special Piping Materials is tested in accordance with respective ASTM standards, ASME standards and relevant international specifications. If we need to subcontract our testing to an external company, then we use NAMAS/UKAS and ISO 17025 approved test houses to ensure reliability and credibility.
Destructive testing includes a whole range of procedures, including the following typical tests:
Historically, destructive testing has been the preferred testing method of checking metals as it was largely thought that it was the only way to achieve accurate results. As a category, it has been around for as long as humans have been able to break down metals to understand its structure and compare it to other samples.
Generally speaking, destructive testing methods are designed to intentionally make a material fail so that its robustness can be analysed, and the point of failure can be analysed. Analysing and recording the failure of the material is sometimes done with high-speed cameras, sound detectors or stress gauges. This is so that the exact moment failure occurs can be detected and so it can be viewed later in slow motion.
Destructive testing procedures can either follow specific standards or they can be tailored to reproduce a particular environmental condition.
Destructive testing does have many advantages. These include the following:
It also allows you to look at the items on a molecular level to determine the exact chemical composition of an object.
Often, destructive methods of testing can be used effectively to determine the stability and performance of a material or product before it is mass produced. This means that you can understand its durability and before it reaches the wider market.
Also, destructive testing is often easier to carry out and easier to interpret than its non-destructive testing counterparts.
The main negative of destructive testing is made obvious by its name; That it results in the test sample or area being irreversibly damaged or destroyed during the procedure.
There is a wide range of different destructive testing procedures, all of which Special Piping Materials can arrange to be carried out in specific and licensed test-houses around the world. Here are just a few of them:
There are many other types of destructive testing available which include:
