Abstract

A fusion joint test system for a saddle fusion joint on a pipe includes a movable sealing mechanism and computer for automatically testing a saddle interface, or fusion joint. The test system controllably pressurizes a substantially isolated area about the fusion joint to a set pressure using a fluid pressure source. A pressure sensor senses a change in pressure about the fusion joint after pressurization and a computer electronically determines whether the fusion joint is within an acceptable integrity range.
