Document Type and Number:
WIPO Patent Application WO/2024/001116
Kind Code:
A1
Abstract:
The present disclosure relates to a device and method for testing the hydrogen permeability of a non-metallic pipe. The device for testing the hydrogen permeability of a non-metallic pipe comprises: a pipe sealing member, a test cylinder, a high-pressure gas source, an exhaust pipe, a vacuum pump, and a pressure sensor. A plurality of circumferential reinforcement members are provided on the circumferential inner wall surface of a body of the test cylinder and used for making contact with the outer surface of a pipe to be tested that is placed in the test cylinder and circumferentially reinforcing the pipe to be tested.
