Steel mesh skeleton plastic composite pipe plan selection key 4), indoor plumbing through the floor, when the beams and walls, the pipe shall not effect any construction layout loads. When the pipeline crossing concrete, masonry and other load-bearing components, it is necessary to set the maintenance sleeve. Indoor plumbing may not matter in the interior construction of the foundation through the underside of the following shall not be built through the settlement joint between things. Pipe joints shall be buried in the load-bearing walls, beams, slabs, columns. 5), outdoor buried steel mesh skeleton plastic (polyethylene) composite pipeline should be buried below the frost line formation seasonal, Pipe top casing height should not exceed 6m; while under the roadway or farmland, tube top casing height not less than lm; beautify vaginal discharge, not less than 0.7m. Parallel construction of the external walls of the pipe, when the bottom of the tube wall above the base, leather piping and wall spacing of not less than lm pe drainage specifications, tube top casing should not be less than 0.5m. 6), buried steel mesh skeleton plastic (polyethylene) composite pipeline not crossing in bedrock structures below. When buried pipelines and other municipal interludes, not through the drainage pipes and heating pipes below. Interspersed with spacing between the pipe should not be less than 200mm; or interspersed with heating pipes laid in parallel, the pipeline must not be laid in the soil temperature is greater than 40 ℃ heating pipe around the area; if necessary, set up in the high temperature region of the manufacturers of soil Supply pe drain pipe is adopted to deal with the adiabatic temperature interval approach. 7), the same pipeline system should use the same interface connector. Buried pipeline should be chosen convergence fused joints. Elected with a flanged joint, should adopt appropriate measures for flanges and corrosion of fasteners according to soil conditions workplace. Steel wire Skeleton plastic (polyethylene) composite pipe and other piping materials convergence of different transition joints, should be used by well coordinated joint supply pipe plant. Our first developed in 1964, the ultra-high molecular weight polyethylene pipe and put into industrial production. Premise that time is limited, the molecular weight of about 1.5 million, followed by improving the skills of the craft, the molecular weight of up to one million currently to 400 million or more. Ultra high molecular weight polyethylene pipe to carry is also very agile pe drains, 80 years ago, the world annual growth rate of 8.5 percent even into the next 80 years, increase the rate of up to 15% to 20%. Steel mesh skeleton plastic composite pipe UHMWPE pipe has been the effect of the national Ministry of Science and Technology as the focus of the implementation of the national program, is new information, new chemical products. An ultra-high molecular weight polyethylene pipe product features 1, high wear characteristics of ultra-high molecular tubes molecular weight of up to 200 million or more (currently there are more than 4.5 million reported in the country), the smallest wear index, it has a very high resistance to sliding friction. Wear 6.6 times higher than ordinary steel, stainless steel, 27.3 times. Is 17.9 times the phenol resin, nylon 6 six times, four times polyethylene, substantial progress in the use life of the pipeline. 2, corrosion resistance because of the ultra-high molecular weight polyethylene (UHMW-PE) is a saturated molecular structure commissure, so its high chemical invariance, this product can withstand harsh chemical corrosion, except for some strong acid at high temperatures Under the subtle erosion, but in other lye, acid in from erosion. Can be used in concentrations of less than 80% of concentrated hydrochloric acid, the sulfuric acid concentration of less than 75%, less than 20% concentration of nitric acid are quite the same. pe drain manufacturers | unblocked building materials (certified) | pe drainage provided by Foshan City Building Material Co., unimpeded. Building Materials Co., Ltd., Dongguan City unimpeded (www.0769pe.com) is Dongguan, Guangdong, composite pipe leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the flow of building materials led the staff warmly welcome all inquiries negotiations to create a better future flow of building materials.
