PE possession of medium density polyethylene pipe and high-density polyethylene pipe. More suitable for conveying gaseous artificial gas, natural gas, liquefied petroleum gas, or mainly used to transport natural gas. The PVC pipe is mainly used to transport drinking water, waste water, chemicals, heating fluid and coolant, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems applications. Its use has some limitations. CPVC pipe is widely used in urban power grid construction and transformation; municipal renovation project; civil airport construction; engineering parks, residential construction; transportation, road and bridge construction city street cabling glass pipe, mainly used in the power industry. PPR pipe low hardness, rigidity difference in handling, construction should be protected, likely to cause secondary damage to the pipe fitting. PPR pipe there is a certain low temperature brittleness, can not be installed on the pipeline pressure, percussion, vulnerable to external sites cover protector if necessary. Compared, PE pipe, use of CPVC pipe is limited, more suitable for use in the power industry, poor rigidity PPR pipe, easy fault RPMP, glass pipe comparison, then are not these disadvantages, glass pipe and more suitable for application in the field of water treatment duct. Pressure test glass pipe flushing ① increased in order to reduce temporary pipeline purge, purge pressure test to save time, improve the passing rate of the purge pressure test, pipeline pressure testing, purging work as systems, patches, pressure levels were glass steel prices pressure test must be prepared before the purge program and construction. ② pipeline pressure test using clean water, when attached to a stainless steel piping when testing and flushing, chloride ion content in water should not exceed 25 × 10 (25ppm), pipeline pressure test and flushing procedures to implement the provisions of the general contractor. ③ When the pressure test, unrelated persons allowed to enter. Pressure test is completed, the pipeline can not be repaired. RPMP, Xiong Wong Tai (certified), Yushu glass pipe provided by Xiong Wang Thai Plastic Products Factory.
