Non-Destructive testing

Some factors that determine the best NDT method

There are a variety of types of Non-Destructive Testing (NDT) methods, and it is essential to know the conditions to select the proper testing technique. 

First of all, it is important to consider the type of material being tested. A non-magnetic material can not be tested with Magnetic Particle Testing. 

The thickness of the material is also essential. Ultrasonic Testing is not effective in material that is less than 3/8″. 

Next, the possible defect needs to be considered. Is the defect internal or on the surface? Magnetic Particle Testing(MT) or Liquid Penetrant Testing (PT) is utilized for surface indications, and Radiographic Testing or Ultrasonic Testing is used for internal defects. 

The accessibility of the part helps determine the best NDT method as well.  For Magnetic Particle Testing (MT), the location being tested needs to be able to accommodate the equipment. 

Finally, regulatory or code compliance helps determine the best testing method. Many codes have specific testing requirements that must be followed.

Non-destructive testing uses instruments and materials to test welds.

What are some examples of non-destructive testing or evaluation? + -

Some examples of NDE/NDT services that we offer are: Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), Ultrasonic Testing (UT), X-Ray Fluorescence (PMI), hardness testing and Ferrite Testing.

What type of equipment requires non-destructive testing? + -

Many types of equipment have code and regulatory compliance requirements for regular inspection and testing.
Additionally, many companies perform NDT on in-service equipment to ensure that the equipment is free from defects that could cause an unplanned production issue.

NDT can prevent failures in mining equipment, steel production, food processing equipment and any other equipment with steel components.
