HomeServices Liquid Penetrant Testing (PT)

Effectively locating surface-breaking defects in all non-porous materials

Liquid penetrant testing (PT) is widely considered the most common non-destructive testing method, enabling our technicians to detect surface flaws such as hairline cracks, surface porosity and fatigue cracks on in-service components in a wide range of energy infrastructures. Liquid penetrant inspection is a simple process where a liquid penetrant is applied to the surface of a part. Sufficient time is allowed (dwell) for the liquid to penetrate surface discontinuities. The excess penetrant is then removed and a blotter (developer) is applied, making the part ready to be evaluated.

Shaw Pipeline Services technicians follow meticulous, pre-approved liquid penetrant testing procedures, ensuring quick detection of surface flaws. With our vast branch network, we can mobilize an inspection team to virtually any project location. With more qualified and experienced technicians, Shaw Pipeline Services provides liquid penetrant testing services that provide our customers with a proper inspection the first time, every time.
