Abstract

The invention discloses a water pressure testing device for a high-pressure-resisting oil-gas pipeline. The device comprises a testing base, a piston plate, a water storing tank, a water pressure testing barrel, a piston rod, a slipping-preventing propping device and a high-pressure-resistant oil-gas pipeline, wherein a pipe fixing clamp is welded to the upper end of the testing base; the high-pressure-resistant oil-gas pipeline is clamped through the pipe fixing clamp; flange plates are arranged at two ends of the high-pressure-resistant oil-gas pipeline and are connected to end sealing plates through bolts; the water pressure testing barrel is welded to the outer side of the end sealing plate which is connected to one end of the high-pressure-resistant oil-gas pipeline. The device is convenient to assemble and disassemble, and high in stability; water is pumped into the water pressure testing barrel to pressurize to drive the piston plate to forwards slide so as to compress air in acompressing chamber, and thus the pressure resistance of the high-pressure-resistant oil-gas pipeline can be detected; the operation is convenient and quick; the detection and test are easy to operate; the device is applicable to the performance testing of the high-pressure-resistant oil-gas pipeline.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline detection, in particular to a water pressure testing device for high pressure oil and gas pipelines. Background technique [0002] Oil and gas pipelines are responsible for the transmission of a large number of oil and gas resources in my country, which is related to national security and the harmonious and stable development of social economy. The pressure resistance of oil and gas pipelines must be strictly required, which can effectively avoid or reduce losses. [0003] With the continuous increase of oil and gas pipeline construction and mileage, the frequency of oil and gas pipeline leakage time caused by excessive pressure and other problems is gradually increasing. It is necessary to strictly test the pressure resistance of oil and gas pipelines before laying them in order to The pipelines that meet the standards are screened out for further installation and laying. However, t...
