Plumbing pipe installation process knowledge
Plumbing fittings Pipeline installation process, can be stratified or single set of hydraulic test.All the pipeline working pressure and test pressure were: low area working pressure of 0.4Mpa, the test pressure of 0.6Mpa, high and middle area work Pressure to 0.6Mpa calculation, the test pressure of 0.9Mpa. After the installation of the pipeline system and then a comprehensive inspection, check the installed pipes, valves, gaskets, fasteners, etc., all in line with the design and technical specifications after the delineation And the pipe together with the pressure test accessories removed, put on the temporary short tube, all Kai Department Department blockade, and from the lowest water injection, the height of the deflation of the pressure test pipeline flushing until the dirt rinse, and Do a good job of purging and cleaning records and pressure test records and other work plumbing pipe test pressure of 1.5 times the system working pressure, but not greater than the allowable pressure of the pipe test should be slowly irrigation, should be done after the seal is filled Check. Pressurized hand pump should be slowly pressurized to the test pressure, the regulator 1h, the pressure drop is less than 0.05Mpa, and then dropped to 1.15 times the working pressure for 2 hours, the appearance of the inspection, impermeable leakage pressure drop Not more than 0.03Mpa is qualified
