Microleakage Testing

Microleakage is defined as any physical form of any chemical or mixture of chemicals, the unintended or concealed leakage of which from equipment in industrial premises occurs.

Valves have evolved from meeting the basic conditions of limiting internal leakage, external leakage and handling flexibility, to the need to meet the requirements of valves with minor emissions to the external environment.

As the global green sustainability strategy continues to advance, environmental protection has become an ongoing concern and  low leakage valves are now the first choice for major oil companies.

Testing Sandards：

Fire resistance test

Valves in the use of flammable and explosive substances in the media, there is a risk of fire or explosion, the valve requires a special design so that the valve after a certain period of fire still has a certain sealing performance and operational performance.

Valveman professional team can provide valve fire resistance test.

Testing process：

Fluidity testing

The flow characteristics and resistance characteristics test  of valves is an important parameter to identify the technical level of the product and ensure the quality of the product, and is an important step to ensure the normal work of the pipeline flow control system. Applicable to the determination of gate valves, globe valves, check valves, ball valves, butterfly valves, regulating valves, etc. Valveman's professional team can provide testing services for.

Valve Low Temperature Testing

The valve cryogenic test is a simulation of the valve's low or ultra-low temperature working conditions, the valve will be placed in the low temperature environment to check its internal or external leakage. It is mainly applied to safety valves, gate valves, globe valves, check valves, ball valves, butterfly valves, regulating valves, etc. in LNG, LPG, LEG, air separation and other cryogenic industries. Valveman's professional team can provide testing services for.

Vacuum Testing

Vacuum valvesare vacuum components used in vacuum systems to isolate airflow, regulate airflow flow and distribute airflow, and they occupy an important position in both simple and complex vacuum systems. The size of their leakage rate often becomes the shortcoming of a vacuum system to reach a certain vacuum level. Valve vacuum testing is important and Valveman's professional team can provide testing services for.
