Currently, there are no authorities to carry out specialized construction skills assessment and management steel skeleton plastic composite pipe work, the provisions of the country is also inconsistent. Construction usually provide staff training and assessment by the pipe manufacturer, and issue a certificate of qualified personnel. When formulating the requirements of competent authorities, should the appropriate regulations. Check beforehand material specifications, quantity and quality of the situation, in order to ensure project quality and progress. Of this section is to ensure that the basic conditions for the welding job. Welding quality due to pollution and a serious decline in the welding surface, surface contamination, including dust, mud, oil and any other foreign matter. Meanwhile, the material itself is not conducive to fusion welding the oxide layer surface, and therefore needs to be removed before the predetermined welding oxide layer. After a long time, if not welded pipe assembly pe water supply plant, the treated surface again oxidation, under normal circumstances, can not be welded when, when intervals over 24 hours or melt contaminated area should be fused to exit and re- deal with. Different manufacturers of pipes and fittings with the size (with the gap) is different, fused and sleeve resistance welding area is not the same, so there is no universal welding process, which should be based on technical documents provided by the manufacturer welding requirements. When the ambient temperature is too low, the material is also correspondingly lower body temperature, such as not taking appropriate insulation or preheat measures that may affect the quality of welding. Black piping intense solar radiation in the lower surface temperature up to 50'C. When the ambient temperature is too high or strong solar radiation, high temperature product base pe pipe, and welding process because of exposure to form fused joints on both sides of the temperature significantly inequality pe water pipe prices, there have been welded or single side flash and, therefore, should be taken to adjust the shade or welding processes and other measures. Winds can lead to contamination of the fusion zone and the formation of air convection inside the tubes, leading to rapid cooling joints. Pollution affects the quality of welding welding, cooling too quickly are likely to form false welding or poor plastic welded joints. Steel Skeleton plastic composite pipe in the wall of the hole mesh steel mesh or steel reinforced plastic composite pipe collectively. The new pipeline is spent with high-strength steel mesh skeleton and thermoplastic polyethylene as raw material, wire wrapped polyethylene plastic pipe network as a skeleton reinforced body, high density polyethylene (HDPE) as the matrix, using high-performance HDPE The steel skeleton binder resin modified with inner and outer storey density polyethylene tightly connected together, so that it has an excellent synergistic effect. Because of the high strength steel reinforced body is coated in a continuous thermoplastic, hence this composite pipe steel and plastic pipe to overcome their shortcomings, while maintaining the steel and plastic pipe respective advantages. Steel mesh skeleton plastic composite pipe, using high-quality materials and advanced production technology, so that it has a higher pressure resistance. Meanwhile, the composite pipe has excellent flexibility pe water pipe supply, suitable for long distance buried with water, gas pipeline system. Pipe steel mesh skeleton polyethylene pipe is used polyethylene fused pipe. Connection, use the pipe heating element inside the outer plastic pipes and pipe fittings inner plastic melt, the pipes and fittings are connected together reliably.
