PE-I polythene pipe fuse head phased array test block

The phased array test block is suitable for the phased array ultrasonic testing of the PE pipe fusion joint with nominal diameter of 40 ~ 400mm.

PE-I is used for beam calibration, TCG correction and adjustment of detection sensitivity. The testing surface of the test block is a plane or a surface with a certain curvature radius, and the specifications and requirements should conform to the following figure. The model of the PE-I test block, the corresponding radius of curvature and the applicable welding joint range are shown in the table below.
