Frequently Asked Questions
Q1: What is the applicable wall thickness range of pipes that the fixture can match?
The fixture is compatible with pipe wall thicknesses ranging from 2mm to 30mm. Its adjustable clamping structure can adapt to different wall thickness deviations, ensuring stable sealing regardless of minor thickness variations in pipe products.
Q2: What is the temperature resistance range of the fixture's sealing elements, and which test scenarios is it suitable for?
The sealing elements of the fixture have a temperature resistance range of -20℃ to 150℃. This wide range allows the fixture to be applied in both room-temperature hydrostatic tests and high-temperature pressure aging tests for plastic pipes.
Q3: What is the recommended tightening torque for the fixture's fastening components during installation?
The recommended tightening torque is 25-40 N*m, depending on the fixture size. Adhering to this torque range can prevent over-tightening that may damage the fixture or pipe ports, while also ensuring sufficient sealing pressure.
Q4: How long is the recommended calibration interval for the fixture to maintain its sealing performance?
The fixture should undergo a sealing performance calibration every 12 months under standard usage conditions. The calibration mainly checks the integrity of the sealing ring and the deformation of the clamping structure to guarantee consistent test accuracy.
Q5: Which types of test media are compatible with the fixture, and why?
The fixture is compatible with common test media such as deionized water, glycerol aqueous solution, and corrosion-inhibiting fluids. Its 304 stainless steel components and fluororubber seals have excellent chemical stability, avoiding reactions with these media that could affect test results.
