This is a set used forGas valves, gas pipelines, gas pipes, corrugated pipes, stainless steel corrugated pipes, pipe fittings jointsWaiting for the productPressure resistance test, airtightness leakage detection, and sealing durability testThe specialized equipment is widely used for testing in gas appliance factories, valve factories, pipe factories, and gas companies.

1、 Equipment usage

1. Valve water pressure and air tightness test machine Gas pipe pressure and air tightnesstest bench
   

   Conduct hydraulic/pneumatic pressure tests on valves, gas pipes, and fittings to detect any cracks, leaks, or deformations.

2. Air tightness leakage test (core)

   Introduce compressed air/nitrogen, maintain pressure for a certain period of time, and determine whether there is a leak through pressure drop. It is suitable for safety testing of flammable and explosive media products such as gas and coal gas.

3. Sealing/lifespan test

   Repeatedly open and close the valve, maintain pressure, and detect the deterioration of sealing performance and fatigue life.

4. Pressure holding, pressure relief, and explosion testing (optional)

2、 Working principle

• adoptPneumatic booster pump/electric booster pumpProvide high-pressure gas or water source, with stable and adjustable pressure.

• Fixtures clamp the sample, automatically inflate/hydrate andPressure holding timer.
