Description :

　　Coated composite steel pipe, this product is a new type of pipeline material recently developed in China. It adopts a composite structure with both internal and external coated protective layers, and a reinforced welded steel pipe or seamless pressure bearing steel pipe in the middle. It overcomes the defects of easy rusting, corrosion, high pollution, low strength, and easy deformation of plastic pipes, integrates the common advantages of steel pipes and plastic products, and is an environmentally friendly product that is widely promoted and used.

　　Its construction and installation should follow certain key points:

　　1. According to the technical specifications for building water supply coated composite pipe engineering

　　CECS125:2001 execution.

　　2. The following construction equipment should be selected for plastic coated steel pipes:

　　(1) Cutting should be done using a metal saw; (2) Special groove rolling machines should be used for groove pressing; (3) Bending pipes should be done using a bending machine for cold bending; (4) The threading should be carried out using an electric threading machine for pipe thread processing; (5) The deburring and corner processing of coated steel pipe ports should be carried out using a file; (6) The application of high-strength inorganic solvent liquid epoxy resin coating should use a small brush or toothbrush.

　　3. The construction procedure for coated steel pipes should meet the following requirements:

　　(1) Plastic coated steel pipes should not be buried in reinforced concrete structural layers; (2) Welding is prohibited during the installation of plastic coated steel pipes; (3) The pipe opening should be promptly sealed; (4) During transportation, loading and unloading, and construction on site, it is strictly prohibited to throw or violently impact coated steel pipes; (5) When installing plastic coated steel pipes, if the pipe diameter is not greater than DN50, a pipe bending machine can be used for cold bending, but the bending curvature radius should not be less than 8 times the pipe diameter, and the bending angle should not exceed 10 degrees; deg;。

　　1. Product standard: Water supply coated composite steel pipe

　　CJ/T120-2000 Technical Specification for Building Water Supply Coating Composite Pipe Engineering CECS125:2001 Safety Evaluation Standard for Domestic Drinking Water Transmission and Distribution Equipment and Protective Materials GB/T, Engineering Standard Code for Design of Building Water Supply and Drainage GB 50015-2003 Code for Acceptance of Construction Quality of Building Water Supply, Drainage and Heating Engineering GB50242-2002 Plastic lined Steel Pipe Environmental Protection Factors The hype has been exhausted. Tianjin Xingbo reported that in September, the traditional peak season of "Golden September and Silver October" plastic lined steel pipes, and now all parties in the market do not have much confidence in the September quotation. Due to the relatively high prices of recent gear quotes, many people are concerned that the early quotes may overdraw the peak season quotes for cash weighing, so they generally hold a cautious attitude. In addition, the performance of the demand side is not particularly good, and the purchases of end users are still not active, resulting in a limited market for the latter. Overall, it is expected that cheap imported products will remain stable in the city next week, with a moderate to weak performance.
