In the family decoration, PPR pipe has the advantages of convenient operation, long service life, light weight and corrosion resistance, and is the most widely used water pipe. But if the water pipe installation is improper, it is likely to bring the consequences of leakage and burst.
Problem 1:PP-R pipe intermediate to produce small holes burst.
Causes: pipe external injured have scratches, holes or long-term exposed outdoor ultraviolet weathering interaction occurred off the block phenomenon, resulting in pipe wall thinning on the injury, which is not up to the design pressure.
Solution: pay attention to the protection of the construction of the pipe, so as to avoid man-made damage to the pipe.
Are good Shandong Jianlong Plastic Co., Ltd. focus on 30 years of water supply pipe suppliers, the production of Shandong PVC pipe, Shandong PVC pipes, PVC drainage pipe in Shandong, Shandong PP--R pipe, PVC-U pipes, pipe fittings products to meet the PVC-U water supply pipe implementation of GB / T 10002.1-2006 standard ", conforms to the trend of historical development. And the operation is simple, the quality is good, very few small hole burst situation.
Problem 2:PP-R pipe in the middle of a burst meter fancy burst.
Cause: the actual hydraulic pressure exceeds the design pressure or temperature of the pipe.
Solution: at the end of the water heater and other transient temperature is too high, it is recommended to use metal braided hose.
Yellow flanging welding pipes and fittings 3:PP-R welding, welding is not reliable.
Cause: this phenomenon can be attributed to the high temperature of welding "". Welding temperature is far more than 270 degrees, high temperature damage to the structure of the material, resulting in PP-R treatment of aging discoloration.
Solution: in strict accordance with the relevant construction specifications for welding and installation, PP-R pipe fitting hot melt socket optimal welding temperature of 260 + 10.
