Ultrasonic testing equipment specification for high pressure seamless steel tubes for pressure vessels

1. The testing equipment consists of ultrasonic flaw detector, probe, mechanical transmission and other necessary auxiliary devices. Detection frequency is 2.5~5MHz.

2, liquid immersion detection using line focus or point focus probe. The contact method is used to detect oblique probes or focused oblique probes that are in good agreement with the surface of the steel tube. Single probe piezoelectric wafer length or diameter is not more than 25mm.
