Hydro Test pressure of an equipment connection ex.?

Question

Accepted Answer

The hydro test pressure of an equipment connection is the pressure at which the connection is tested for leaks and strength.

Hydro test pressure is determined based on the design and operating conditions of the equipment.
It is usually expressed in units of pressure, such as psi or bar.
The test pressure should be higher than the maximum operating pressure to ensure the connection's integrity.
The test pressure may vary depending on the type of equipment and its intended use.
For example, the hydro test pressure for a piping connection in a chemical plant may be 1.5 times the maximum operating pressure.
The hydro test pressure is typically specified in engineering standards and codes.

Accepted Answer

1.3 times the design pressure multiplied by the lowest stress ratio (LSR) for the material of the vessel.

Accepted Answer

The test pressure during this strength test must be maintained to allowable operating pressure (MAOP) for the pipeline

Cylinder Hydro Test Machine – Computer control model

Gas cylinder external measuring machine with water jacket

Suncenter cylinder hydrostatic testing machine(Gas cylinder external measuring machine) is suitable for the most seamless steel cylinder, including: nitrogen cylinder, argon helium cylinders, oxygen cylinders, hydrogen cylinders, carbon dioxide cylinders, LPG/LNG/CNG winding bottle, liquefied gas cylinder etc.. The equipment is controlled by computer, equipped with HP printer to directly print the test report, double water jacket for oxygen bottles and other cylinders, cylinders are widely used in testing station cylinder jacket method of hydrostatic test evaluation.

The machine is mainly used for cylinder pressure test and achievement of gas cylinder volume residual deformation rate.

Working principle: put the cylinder into a water jacket and boost the cylinder by high pressure pump. It will automatically dwell at set pressure and do pressure test on the cylinder. At the same time, the cylinder volume expands under test pressure and squeezed some water from water jacket into the measuring cup, and it is test cylinder volume deformation. The water is transferred to PC by water collection system, the elastic deformation disappears after cylinder relief of pressure, then the water flows back from measuring cup to water jacket. However, the remainning water in the measuring cup is still more than that before boosting the cylinder. The extra water volume is the test gas cylinder volume residual deformation. While the gas cylinder volume residual deformation rate is the ratio of the test gas cylinder volume residual deformation and all deformation.
