Large diameter spiral steel pipe carrying water conservancy in the application of the time to be hydrostatically tested to ensure the quality of spiral piling pipe, usually when the test is to be tested with the test machine. Then the pressure test machine works, what is it? Here everyone to know about it!
Large diameter spiral piling pipe hydrostatic testing machine works:
Large diameter spiral piling pipe hydrostatic testing machine during the pressure test, the first sealing device right through the end of the test tube is sealed at both ends and low-pressure water injection, water injection process through the exhaust valve exhaust air in the tube, filled with water at low pressure through the booster device to the high-pressure water injection tube until the required test pressure booster.
After reaching the required test pressure holding pressure at the stipulated time, if large diameter spiral pipe in the pressure test without leakage, deformation phenomena, proceed relief. Then open end seals, low-pressure water discharge will be sent to test large diameter spiral pipe for visual inspection station to check for suspicious penetration. Pressure test according to the standard required for the pressure curve during automatic recording device records.
