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 calculate ppr pipe fittings, test pressure 0.9Mpa. After the system is installed in the pipeline to do a comprehensive inspection ppr pipe, serious to check pipe has been installed, gaskets, valves, tight firmware, 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, 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. PPR pipe surface craft the question of how to improve? ppr pipe fittings in the production process due to the influence of the environment in a certain pipe surface defects, such as surface roughness or exterior grooves and other defects occur. Ppr pipe fittings manufacturer if the product surface roughness, probably because the host head temperature is too high or too low, resulting in a rough outer surface. Mandrel temperature is low, the body temperature is too low, could easily lead to the inner surface roughness. Cooling water temperature is too high, the surface roughness. Reduce the cooling water temperature, PP-R for the optimum cooling water temperature twenty to thirty degrees Celsius. In this case PP-R pipe fittings manufacturers should check waterway, the existence of the phenomenon of congestion and inadequate water pressure, check whether there is damage to the heating coil, check the raw performance, contact the supplier of raw materials, clean up the mold core temperature, if higher than die zone temperature, open core thermostat, check and clean if there are impurities in the mold. And if the pipe exterior grooves appear, ppr pipe fittings should be checked and adjusted the water curtain sizing sleeve, pressure equalization ppr pipe manufacturers, adjust the angle of the spray nozzle ppr pipe prices, uniform cooling pipes, check sizing sleeve, cutting machines the existence of the object debris, burrs. For pipes that may arise, ppr pipe fittings manufacturer should be possible investigation from the process, after all environmental aspects of the pipe surface quality effects are obvious. ppr pipe manufacturer, Zhengzhou ppr pipe, the pipe is provided by Zhejiang Jie Jie Pipeline Ltd., Zhengzhou office. Zhejiang Jie Pipeline Ltd., Zhengzhou Office (www.pprgc.com) strong, credible, Sheung Shui system in Zhengzhou industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead you hand in cleaning pipes and into the brilliant, for a better future! |
