Abstract

The invention provides a hydrostatic pressure testing device of a pipeline with a joint. The hydrostatic pressure testing device comprises a sealing sleeve and a second flange. The sealing sleeve is arranged on the joint in a sleeving manner. A first flange is arranged on the sealing sleeve. The part, opposite to a pipeline opening, of the sealing sleeve is a spherical face. The second flange is arranged outside the joint in a sleeving manner. The first flange and the second flange are connected through bolts. The hydrostatic pressure testing device is suitable for a pipeline with a joint at only one end and is also suitable for a pipeline with connecting joints at the two ends. The hydrostatic pressure testing device has no limitation on the length of the testing pipeline. According to the hydrostatic pressure testing device, the testing and assembling process is simple and convenient, the testing efficiency is improved, and the testing range is wide.

Description

technical field [0001] The invention relates to the field of pipeline manufacturing, in particular to a hydrostatic pressure testing device for pipelines with joints. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] Expansion joints, also called pipeline compensation joints, are new products that connect pumps, valves, pipelines and other equipment with pipelines. The equipment, pipelines and expansion joint...
