Steel mesh skeleton plastic composite pipe planning a selection key), project planning should be consistent with the relevant national planning norms, norms, rules demand. Traffic planning steel mesh skeleton plastic (polyethylene) composite pipeline system and hydraulic accounting pe composite pipe manufacturers, when used in the construction of water supply pipeline project, according to the current national standard "construction of water supply and sewerage planning norms" GB 50015, "active spray save water system planning norms "GB 50084 accounting rules; when used outdoors buried water pipeline project, according to the current national standard" outdoor water supply planning norms)) GB 50013 accounting rules, and "water supply steel mesh skeleton plastic ( PE) composite pipeline engineering point of order "CECS 181: 2005 2), steel mesh skeleton plastic (polyethylene) composite pipeline project, the choice should be supporting steel skeleton of polyethylene pipe. It is necessary to fit the needs of the existing national commodity specification chosen pipes, fittings and convergence of various joints and other parts used in closed channels, by supporting the production and supply of specialized factories, and have the appropriate product quality inspection report and pre-qualified certificate. 3), the construction of water supply piping layout should be consistent with national norms, "the construction of water supply and sewerage planning norms" GB 50015-2003 Chapter 3 indoor plumbing rules should be set out, when it is necessary to build demand hid pe composite pipe, the pipe should be set ducts, tube wells, pipe hole or ceiling, dark set of pipes should be accessible for inspection and maintenance, and shall not affect the safety of the construction layout. Steel mesh skeleton plastic composite pipe construction, equipment key 1), before the next pipe pipe shall be visually inspect merchandise itemized specification pe composite pipe fittings, those who do not fit the norm, is prohibited under the pipe laying. 2), under the transfer pipe should Qingtai, light, ban persistent in the groove, roll or with a forklift, forklifts, and other persistent traction transfer pipe. 3), not when the water in the trench laying pipe, should lay with the shop at the time with the digging. Length according to the length of the groove interface concluded that the choice of depth 50-100mm, width of not less than the pipe diameter. After the interface is complete, immediately in the groove part coarse sand backfill compaction. 4) When it is necessary to cut the pipe cladding tube length, mechanical methods should be used to cut. Cut end should be flat and should be straight pipe axis. Prohibit the use of fire to clear cut. 5) changes in the diameter of the pipe or pick out parts of the branch pipe, it is necessary to choose a pipe. Ban on pipes, fittings opening reception. 6), it is necessary to apply the slope of the demand by the planning control, elevation error not greater than the current national standard "and drainage facilities construction and closing specification" GB 50268 of the rules of prestressed concrete pipe water supply values. 7), fused convergence and convergence should be selected in the lower flange or near to the minimum ambient temperature. Coping parts pipeline convergence convergence socket, sleeves, seals and other parts finishing clean, not with soil, water and other impurities. Flange interface of choice loose flanges, bolts and other metal products, and reference should be based on site soil corrosion adopt appropriate normative approach. pe composite pipe composite pipe _ _pe unimpeded flow of building materials provided by the City Building Materials Co., Ltd ..
