NDT Services: Compressed Gas

TKS recertifies DOT 3A, 3AA, 3AX, 3AAX and 3T trailer1cylinders using acoustic emission in lieu of hydrostatic testing. TKS’ U.S. DOT special permit # 14584 allows for AET on DOT 3A, 3AA, 3AX, 3AAX and 3T cylinders.

Tube Trailer Recertification

During our hydrostatic test, the SCBA cylinder is examined to ensure it can safely hold its rated pressure. This regular testing is crucial because SCBA cylinders, or any compressed gas cylinder for that matter, can rupture if there’s degradation in structural integrity.
