Pneumatic & Hydrostatic Pressure Testing

我们提供多种静水和气动压力方法,用于评估任何产品。

静水压力测试

A hydrostatic pressure test uses liquid as the medium for applying pressure. During testing, vessels such as pipes, tubing, fuel assemblies, boiler components or fuel tanks are filled with water (or another specified liquid). The component is pressurized to a certain level for a specific amount of time, based on customer or industry requirements. Acceptance of the test is based on the ability of the material under test to hold the specified pressure without deformation of the material or leakage.

深度测试和淹没测试

These methods are performed to determine how a product will react underwater, or while under external pressure.

Pneumatic Pressure Testing

Unlike the hydrostatic pressure test, pneumatic pressure testing is performed using air pressure, and is often used to find leaks in sealing systems, ductworks, or ventilation pipes. Using a pressure gauge, pneumatic testing assesses individual components and complete systems to isolate failures and determine pressure rating.

Proof Pressure Testing

Also known as the modified hydrostatic test, proof pressure testing uses liquid to apply a force above a product’s intended operating pressure. The results of the test determine whether the product can withstand the stress without permanent damage.

Ultimate Pressure Testing

Ultimate pressure testing is performed to determine the maximum pressure level that a component can withstand before failure. Our experts can help you determine safe operating levels for your equipment, helping to prevent catastrophic issues in the field.

爆裂压力测试

This test increases the pressure applied to the test item until a physical failure occurs.

Cyclic Pressure testing 640 x 480

循环压力测试

Cyclic pressure testing evaluates how products handle pressure and fatigue over their service lifespan.

Cyclic pressure testing applies liquid or air pressure at a cyclical rate, which is typically a specified amount of time on and time off. Cyclic pressure tests help to determine a product’s susceptibility to fatigue failure when in use. We can reach pressure ramp rates of up to 200,000 PSI per second.

Mechanical and Structural Pressure Testing 640 x 480
