PPR pipe specifications, PPR pipe, Qingdao Jitai presses

1, the test pressure for the pipeline system 1.5 times the working pressure, but not less than 0.6Mpa2, for PP-R pipe system, water tests generally require 24 hours after installation of the pipe connection for 3, water pressure test before PPR pipe, the pipe should take safe and effective fixed and protective measures, but the joint Ming Lu 4, hydrostatic testing step (1) pressure test pipe ends sealing PPR pipe extruder, slow water, while the gas pipeline exclusion (2) is filled with water after , watertight checks (3) is appropriate pressurization pressure hand pump slowly, the rise time shall not be less than 10 minutes (4) increased to the test pressure, the pressure is stopped, the regulator for 1 hour to observe whether there is leaking joints ( 5) regulation one hour, added pressure to the test pressure, internal pressure drop of no more than 15 minutes, 0.05Mpa qualified PPR pipe connection technology: general no longer leaking, reliability is extremely high. This is not to say that the water is not defective PPR pipes, high temperature, pressure somewhat less, long-term working temperature should not exceed 70 ℃; each length limited PPR pipe production equipment, and can not bend construction PPR pipe production line, if long distance pipeline or more around the corner, in the construction necessary to use a large number of joint; pipe fittings cheap but the price is relatively high. From the overall performance is concerned, PPR pipe is the higher cost of the pipe, so the material of choice for home improvement plumbing transformation.
