Post Weld Heat Treatment
Post Weld Heat Treatment is a controlled process in which a material that has been welded is reheated to a temperature below its lower critical transformation temperature, and then it is held at that temperature for a specified amount of time.
Holiday Test
A Holiday Test is a non-destructive test method applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids. Holiday testing involves checking an electric circuit to see if current flows to complete the circuit. This testing is used to find coating film discontinuities that are not readily visible.
Computerize Current Test
This test is used to identify defects in material that have undergone coating. This method detects any leakage in the impressed current system on the pipeline. Done without the dismantlement of the pipeline.
Positive Material Identification – Portable XRF
Positive Material Identification is a method to identify the chemical composition of a material.
Leeb Hardness Testing
Leeb hardness testing is one of the four most used methods for testing metal hardness. It can be done on-site.
