DESTRUCTIVE TESTING
Destructive testing methods are designed to be just that – destructive. This may seem counter-intuitive, but it works by intentionally making a material fail so that the point of failure can be analysed.
Analysing and recording the failure of the material can be done in a variety of ways, using high-speed cameras, sound detectors or stress gauges.
Destructive testing procedures can either follow specific standards or they can be tailored to reproduce a particular environmental condition. Special Piping Materials works with a network of reputable testing houses around the globe who can meet any requirements that our discerning clients have.
The destructive tests we can organise prior to the delivery of our products include:
• Product analysis
• G48 corrosion test
• Micrographic examination
• Ferrite and phase count
• Charpy impact test
• Tensile test
Destructive testing has many advantages such as it:
• Verifies properties of a material
• Determines quality of welds
• Helps you to reduce failures, accidents and costs
• Determines impact resistance
• Analyses ductility
• Can produce knowledge about yield and ultimate tensile strength, fracture toughness and fatigue
strength.
• Can form a key part of engineering critical assessments
• Provides materials characterisation
• Can find fabrication validation
• Predicts service life
• Can see the molecular level of at item in order 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.
Further to this, 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.
