The pipeline hydrostatic burst pressure tester is a portable pipeline hydraulic pressure test unit that can generate and output hydraulic pressure up to 408MPa maximum. And it comprises air powered hydraulic pump, control kit and high-pressure fittings. The hydrostatic pressure test machine can conveniently perform hydrostatic pressure testing and burst pressure testing on various industrial pipelines, such as petroleum pipelines, manifolds, chemical process pipelines, thermal pipelines. And it is also suitable to carry out hydrostatic test on valves and pressure vessels.
Normally, the pressure testing is necessary for various pipelines, so as to verify whether the integrity and airtight of the pipeline meet the design requirements. The pipeline pressure test is mainly includes hydrostatic pressure test and tightness test. And the hydrostatic test is subdivided into pressure resistance test and pressure burst test. Considering the dangers of intermediate pressure gas and high pressure gas, hydrostatic pressure test mostly uses water as the test medium. And the tightness test mostly takes low-pressure gas as the test medium, of course, water is also used for leak detection.
The pipeline hydrostatic pressure tester is a versatile pipeline hydraulic pressure test equipment. And it can carry out pressure resistance test, pressure burst test and leakage test on pipelines. In addition, the pipeline hydrostatic pressure test machine is small in dimension and easy to move, so it can be carried to the work site for online pressure testing of pipelines.
Before performing hydrostatic pressure test on the pipeline, pre-fill water into the pipeline to exhaust the air. (Find out Why Exhaust Air is Required in Hydrostatic Test). Then connect the pipe to the test machine with a high-pressure hose. Preset a testing pressure, and the machine will inject hydraulic flow at your preset pressure into the pipeline and then maintain the pressure. After the pressure maintenance period, if there is no leakage or crack in the pipeline, and there is no excessive pressure drop, it proves that the pressure resistance and tightness of the pipeline is qualified. The pipeline burst pressure test comes after the pipeline hydrostatic pressure test. The machine will inject higher pressure hydraulic flow into the pipeline constantly until it cracks. At this moment, the pressure that causes the pipeline to crack is the burst pressure, which is actually the ultimate pressure that the pipeline can withstand.
If your budget is limited, choose the manual pipeline hydrostatic pressure tester, which has the automatic pressure maintaining function. But you need to manually time and manually unload pressure. And the test results are also determined by human.
If you prefer convenient operation and higher test accuracy, choose the automatic pipeline hydro tester. It has the functions of automatic pressure maintaining, automatic timing and automatic pressure unloading. You only need to set the testing parameters on the built-in test program on the touch screen, and the machine will automatically execute the test process and automatically determine and feedback the test results.
If you use water as the medium for pipeline leak detection, you can directly use the hydrostatic pressure test machine to carry out tightness leak test on pipelines. Since the diffusion rate of gas molecules is much faster than that of liquid molecules, air or gas is used as the medium for leak test in most cases. If you use gas as the medium for leak test instead of liquid, you need to use the pipeline tightness leak test machine. It can pressurize air or gas to 800Bar maximum, and then inject it into the pipeline. After the pressure maintenance period, the soap water method or pressure drop method can be used to determine whether the gas medium in the pipeline is leaking. We provide both manual and automatic pipeline tightness leak detection machines for you to choose. If you choose the automatic pipeline airtightness leak test machine, you only need to set the testing parameters on the built-in test program on the touch screen, and the machine will automatically run the entire test process and automatically determine and feedback the test results.
