Detailed Product Description: | PPR pipe construction system hydrostatic test requirements? Generally we were in the process of pipeline installation, can be layered or single set of hydrostatic test, working pressure and test pressure of all the pipelines are as follows: low pressure areas to work 0.4Mpa, the test pressure is 0.6Mpa, high area and in the area of ??work pressure 0.6Mpa calculated test pressure 0.9Mpa. After the system is installed in the pipeline to do a comprehensive inspection, carefully installed to check the pipes, gaskets, valves, fasteners and so on. . . After all must be consistent with the design and technical specification, the pipes are not suitable and fitting it together to dismantle and put a temporary short tube, all openings will be closed ppr pipe fittings, and irrigation from the lowest point, height deflated! Qualified for the pressure test pipe purging work until until rinse dirt and make a clean sweep of the pressure test records and records of work. The test pressure is 1.5 times the working pressure of the system, but not greater than the allowable pressure pipe. Should slow injection test should be done after checking the seal filled. After pressing the hand pump should slow step to test pressure, the regulator 1h, the pressure drop is less than 0.05Mpa, then dropped to 1.15 times the working pressure regulator 2 hours, visual inspection, no seepage does not leak pressure drop does not exceed 0.03Mpa qualified. Tips: The above are based on questions gathered from clean piping technicians encountered in practical work, for reference, any questions, please timely communication, correct me. Anhui Xinhua College PPR pipe explain how to identify the pros and cons of the people PPR pipe used today are more and more, produce more and more manufacturers are also, however, because of the different materials, and even individual manufacturers for immediate When situations occur jerry quality produced PPR pipe is uneven, following on to introduce how to identify the merits of PPR pipe. The first is expected to tell by looking at the method, a good PPR pipe, looks very bright colors, there are oily feeling bad because of PPR pipe materials which got into some bad plastic as well as lime powder these, so PPR tube unnatural brilliance, the incision is also very dry PPR pipe no oily feel ppr pipe that looks like a chalk like added. The second is the PPR pipe can touch, but also of PPR pipes inside and outside are very smooth, no uneven, there will be no cracks, poor PPR pipe may not so smooth, pipe surface irregularity . The third is by Dian Dian quality PPR pipe, tubing good than poor little heavier ppr pipe PPR pipe ten brands, because good PPR metal fittings generally have more than three or more of water seepage trenches copper pieces, and the copper content is relatively high, copper is relatively long ppr tube top ten brands, relatively thick, so good quality PPR pipe fittings will be slightly heavier. Fourth, can be tested by burning method. Good PPR pipe materials in more than eight Baidu flames when oxygen is sufficient if it wants off, yes yo ah release carbon dioxide and water vapor, and off when there is no other taste and waste generated by the difference The PPR pipe because there are other really mixed plastics and magazines, there will be another flavor and debris off after generation, this can cut a small slice in the PPR pipe with a lighter to extinguish distinguish. ppr pipe price | in cleaning pipes (certified) | Zhengzhou ppr pipe cleaning Pipeline Co. by Zhejiang Zhengzhou offices.
