This machine is one of the most important pieces of equipment for welded pipe fabrication. It carries out product inspection for welded pipe by hydrostatic testing on welded pipe to detect any defects in the weld seam. This operation can also eliminate residual stress in the pipe to a certain level. It uses End Sealing type testing, which is structurally stable and operationally convenient. During the test, specified test pressure is hold at a specified time frame (not more than 40 seconds) before the pressure is gradually released. Test parameter and data are recorded in an Industrial PC.
