TPEP steel pipe for water supply, large-diameter TPEP anti-corrosion steel pipe, anti-corrosion pipeline production plant

Description :

　　TPEP anti-corrosion steel pipe TPEP is a type of anti-corrosion structure, which is a generation of anti-corrosion forms applied to long-distance water transmission pipelines. Compared with traditional transmission pipelines, it has many advantages and features. The external anti-corrosion of the pipeline is 3PE, and the internal anti-corrosion of the pipeline is fused epoxy powder. The anti-corrosion standard of the inner wall of the pipeline has reached food grade The TPEP anti-corrosion steel pipe project produced by Cangzhou Youyi Pipe Industry can be buried and used for 50 years according to national standards to ensure the normal use of the pipeline. TPEP anti-corrosion steel pipe to external 3PE internal fusion bonded epoxy anti-corrosion steel pipe is an upgraded product based on the outer single-layer polyethylene internal epoxy composite steel pipe, and is currently the anti-corrosion form of steel pipes for buried long-distance pipelines. It is a new type of anti-corrosion production line for large-diameter pipelines independently developed by Cangzhou Youyi Pipeline Co., Ltd. The outer wall adopts a three-layer structure anti-corrosion layer formed by hot melt bonding and winding technology, with a bottom layer of epoxy resin, an intermediate layer of adhesive, and an outer layer of polyethylene. The inner wall adopts a thermal spray epoxy powder anti-corrosion method, and the powder is uniformly coated on the surface of the pipe body after high-temperature heating and fusion.

　　Carbonate and bicarbonate ions. The heat aging resistance of polyethylene in S02 needs to be tested for 100 or 200 days. Market insiders also say that the market has always been crazier than the market, with more speculative concepts, and they do not recommend investors to continue chasing after the rise in the market. With the rapid development of strip rolling production and advances in welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of spiral welded steel pipes are increasing, replacing seamless steel pipes in more and more fields. Spiral welded steel pipes are divided into straight seam spiral welded pipes and spiral spiral welded pipes according to the form of the weld seam. In order to achieve the ideal rust removal effect, the abrasive should be selected based on the hardness, original rust level, required surface roughness, coating type, etc. of the straight seam spiral welded pipe equipment. For single-layer epoxy, two-layer or three-layer polyethylene coatings, using a mixture of steel sand and steel shot abrasive is more likely to achieve the ideal rust removal effect. Steel shot has the function of strengthening the surface of steel, while steel grit has the function of etching the surface of steel.

　　The TPEP anti-corrosion process (inner EP and outer 3PE) combines thermosetting epoxy resin powder coating with the characteristics of polyethylene and processing technology, and cleverly combines the three-layer structure polyethylene coating with fusion bonded epoxy powder coating technology, providing a good solution for the corrosion protection of buried steel pipes. The inner wall fusion bonded epoxy resin powder (FBE) anti-corrosion solves the internal anti-corrosion problem of pipelines, with low roughness, smooth inner walls, and good hydraulic performance.
