The sealing performance of sliding pipe fittings is one of the important indexes to evaluate its quality and service life. The following are some common sliding pipe seal performance testing methods:
Air pressure test
Connect the slide fittings to the air source and then pressurize the inside to check for leaks. The pipe fitting is usually pressurized several times in a certain period of time to simulate the pressure change in actual use.
Hydrostatic test
Connect the slide pipe to the water source, pressurize the inside, and check for leakage. Hydraulic testing is suitable for all sliding pipe fittings, especially where leaks are easily checked.
Penetration detection
Use penetrant to penetrate the slip pipe fittings and then check for leaks. Penetration testing is mainly used to check small gaps and pores in metal pipes.
Fluorescence detection
By labeling the liquid or gas with a fluorescent agent, observe whether there is leakage in the slide pipe fitting under a fluorescent lamp. Fluorescence detection has high sensitivity and precision, and is suitable for various types of sliding pipe fittings.
Ultrasonic detection
The ultrasonic detector is used for non-destructive testing of sliding pipe fittings, and whether there is leakage is judged by detecting echo signal. Ultrasonic inspection is suitable for examining complex piping systems and hard-to-reach areas.
Pressure drop detection
The sealing performance of sliding pipe fittings is evaluated by measuring the change of pressure in a certain period of time. If the pressure changes within the specified range, it means that the sealing performance is good; Otherwise, a leak exists.
Flow measurement
The sealing performance of sliding pipe fittings is evaluated by measuring the amount of fluid flowing through them in a certain period of time. If the flow rate is in line with expectations, it means that the sealing performance is good; Otherwise, a leak exists.
It should be noted that the specific sealing performance testing method may vary depending on the type, specification and use environment of the slide pipe fitting. Therefore, in the actual testing process, should follow the relevant operating procedures and technical requirements. If in doubt should consult professional and technical personnel or manufacturer’s advice.
