Detailed Product Description: | The clean pipe _ppr pipe ppr pipe specification _ Luoyang Sino-cleaning pipes available. We are Zhejiang Jie Pipeline Ltd., Zhengzhou Office (www.pprgc.com) at: Zhengzhou specializes in: PP-R hot and cold water pipes, F-PPR performance glass fiber reinforced composite pipes, PP-R pipes and aluminum PPR traditional cast iron pipe, galvanized steel, cement pipes and other pipes, compared with the energy and materials, environmental protection, lightweight, high strength, corrosion resistance, smooth wall without fouling, simple construction and maintenance, long life and other advantages, widely used building water supply and drainage, urban and rural construction, municipal, industrial and agricultural areas of water supply and drainage, city gas, electricity and cable jacket, industrial fluid transport, agriculture and irrigation. PPR pipe officially called random copolymer polypropylene tubes, is currently used in most home improvement projects a water supply pipeline. PPR pipe raw material quality control problems, PPR is made (PP and PE) gas-phase synthesis of a random copolymer polypropylene ppr pipe, its molecular structure is characterized by irregular PE PP molecular link among molecular weight from 300,000 to 800,000 range. The use of raw materials to produce PPR pipes, also known as random copolymer polypropylene pipes, the late 1980s and early 1990s, the development and application of plastic pipe products. With its own excellent performance and a wider range of applications, has occupied a place in the plastic pipe market, is recognized as a green product. But in recent years the market run ppr pipes, PPR plastic pipe above the quality of the analysis also found that PPR pipe market, for example, there were many problems, which largely restricts the healthy development of PPR pipes. Long life: in the normal life of the piping system can be up to 50 years. Notes 1, PP-R pipe with a metal tube or water in addition to connecting using threaded inserts or flanges and other mechanical connections outside ppr pipe, the rest should be using hot melt connection, so that the pipeline integration ppr pipe dn20, no infiltration leak points. 2, PP-R pipe line expansion coefficient larger (0.15mm / m ℃), in surface mounted or buried Concealed pipeline expansion must be taken to prevent deformation technique measures piping. 3, after the pipeline is installed in front of a sealed tube (buried) and cover the decorative layer (non-buried Concealed) must pressure test. Cold water pipe test pressure of 1.5 times the system working pressure, but not less than 1MPa; hot tube test pressure of 2 times the working pressure, but not less than 1.5MPa. Pressure test of time and method of technical rules of order. |
