Abstract

The invention relates to the technical field of pressure testing, and especially relates to pipeline pressure testing equipment. The equipment comprises a supporting rod, a pipeline to be subjected topressure testing and two sealing parts. The supporting rod is arranged in the pipeline to be subjected to pressure testing in a penetrating mode. The two sealing parts are arranged at the two ends ofthe supporting rod respectively and are used for sealing the two ends of the supporting rod and the pipeline to be subjected to pressure testing respectively. Each sealing part is provided with an inlet for a pressure test liquid to flow into the pipeline to be subjected to pressure testing. According to the pipeline pressure testing equipment provided by the invention, in the pipeline pressure testing process, the supporting rod is located in the pipeline and plays a role in supporting the pipeline, so that the pipeline is prevented from being bent in the pressure test process, and the pressure testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pressure testing, in particular to pipeline pressure testing equipment. Background technique [0002] FRP pipelines are widely used in oil fields, covering production, gathering and transportation, sewage treatment, polymer injection and other systems. In recent years, the demand for large-diameter high-pressure gathering and transportation pipelines has been increasing, and pressure tests are required before pipelines leave the factory. However, the installation and connection methods of pipelines are different, and the pressure test tooling is also different. Existing pipeline connection methods mainly include threaded connection, socket-and-socket connection, conical surface bonding, etc. The pressure test equipment for threaded connection and socket-and-lock connection pipes in the market is relatively mature. [0003] At present, the tapered surface bonding pipe is not easy to fix and seal when it ...
