ABSTRACT:
An external tester defines a sealed chamber around a pipe joint, such chamber then being filled with fluid under very high pressure. After introduction of fluid into the test chamber is terminated, a determination is made as to whether or not the pressure is reducing, any such reduction indicating that a leak is present in the pipe joint. To define a test chamber which is perfectly sealed so that fluid will not escape otherwise than through a leak in the pipe joint there are provided longitudinal sealing elements and arcuate sealing elements interrelated with each other and with an insert of the longitudinal elements. The inserts stiffen and mount the longitudinal elements, provide indexing of the casing sections, and prevent extrusion of the seal rubber, all in such a manner that no cracks remain through which the fluid may escape.
