Connecting piece of pipeline heat tracing band and hydrostatic testing machine of pipe

Abstract

The invention discloses a hydrostatic testing machine for a connecting piece and a pipe of a pipeline heat tracing band, and relates to the technical field of pipe testing. The connecting piece of the pipeline heat tracing band is used for facilitating technical reconstruction of a pipe hydrostatic testing machine and comprises an inner ring and an outer ring, the outer ring is arranged on the outer circle of the inner ring in a sleeving mode, the inner ring is formed by splicing a first inner ring unit and a second inner ring unit, the first inner ring unit and the second inner ring unit are each in a semi-circular shape, and the first inner ring unit and the second inner ring unit are each in a semi-circular shape. The first inner ring unit and the second inner ring unit are detachably connected, the outer ring is formed by splicing a first outer ring unit and a second outer ring unit, the first outer ring unit and the second outer ring unit are detachably connected, and the inner side of the first outer ring unit and / or the inner side of the second outer ring are / is provided with a pay-off opening. And the inner ring and the outer ring can rotate relatively. The pipe hydrostatic testing machine comprises the pipeline heat tracing band connecting piece.

Description

technical field [0001] The invention relates to the technical field of pipe material testing, in particular to a hydrostatic testing machine for a connecting piece of a pipe heating cable and a pipe material. Background technique [0002] Pipe hydrostatic test is used to determine the thermoplastic pipe, composite pipe (such as PP-R, PP-B, PP-A, PE, PE-X, PVC, PVC-U, PVC-C) and aluminum-plastic composite pipe and other The pressure breakdown time or the maximum pressure value of instantaneous burst of the pipe under constant internal pressure and constant temperature for a long time. It is a necessary quality inspection test in the production process of plastic pipes. [0003] Hydrostatic testing machine is a kind of equipment used to realize the above test process. One of the hydrostatic testing machines in the prior art includes a water tank of the testing machine, connected to the water tank of the testing machine are multiple water inlet pipes, and the water inlet pipe...
