Pressure Testing (Hydraulic Piping) Pressure testing is a process which is done to check for any errors in the installation or defects in the piping components. Basically the erected system is proof tested using the working fluid to something known as test pressure (usually 1.5 times the working pressure) and checked for leakages or pressure drop.

Hydraulic systems are used in so many automatic machines. It is equipped with a pressure relief valve to maintain the operation pressure of the system at a pre-determined level. Relief valve protects the hydraulic pump and in turn the prime mover from overload quickly in case the system is exposed to overpressure. That's why, characteristics

In a backhoe, power is just flow rate multiplied by hydraulic pressure. The pressure is determined by the operation being performed -- lifting heavy objects or busting through hard ground requires higher pressure than does moving an empty bucket. Relief valves determine the maximum pressure in the hydraulic system.

Pressure tests are a non-destructive way to guarantee the integrity of equipment such as pressure vessels, pipelines, plumbing lines, gas cylinders, boilers and fuel tanks. It is required by the piping codes to confirm that a piping system is able to bear its rated pressure and it has no leaks. Pressure testing, also called hydrostatic testing, is carried out after the cooling or …

For a hydraulic pressure test there are mainly two methods of checking the leakages at the joints. Visual check of the joints (flanges, fittings) to spot any leakages. Visual Check on the pressure gauge to spot any pressure loss. If the line clears the above checks it has then successfully been pressure tested.
