ABSTRACT:
A pipe joint testing device for testing the joint integrity of two connected pipe sections, each having a bore and pressurized with gas at the joint area during testing uses an annular envelope which can be affixed about the annular external joint of two pipe sections being tested. An inner annular header having a gas inlet with openings which communicate circumferentially with the envelope is provided internally of the envelope. A suction line is connected to the header at a tee connection, for example, for drawing gas from the envelope through the openings. In this manner, any gas leaking from the joint at any radial position along the joint will be detected because it will enter through one of the openings in the header.
