Features and application of anticorrosive steel pipe factory

3PE anticorrosion steel pipe factory is generally composed of three layers of structure, the first layer of epoxy powder (FBE > 100 μ m), the second layer of adhesive (AD) 170 ~ 250 μ m, the third layer of polyethylene (PE) 2.5 ~ 3.7mm. The actual operation will be mixed together, and three materials processing and steel pipe firmly form excellent anticorrosive coating. It is generally divided into two types: winding type and circular mold Anticorrosive pipes can be divided into anticorrosive steel pipes and outer wall anticorrosive steel pipes. The anticorrosive lining is mainly cement mortar lined anticorrosive steel pipes factory, which have low cost and can be used as cement mortar anticorrosive coating with cement mortar lining. The application of anti leakage of outer wall corrodes 3PE anticorrosive steel pipes. Anticorrosive technology is the process of coating the outer wall or inner wall of steel pipes to protect the pipes themselves. Various pipes, Such as straight pipe, spiral pipe can be processed At present, the domestic anti-corrosion steel pipe factory has a broad market prospect and is widely used in many fields. The production process of the anti-corrosion steel pipe factory is diverse, and it is widely used in China with 3PE anti-corrosion steel pipe, steel sleeve steel pipe and 8710 anti-corrosion steel pipe. The steel pipe steam composite insulation pipe is generally used for conveying steam or other media at 2.5MPa or below 350 ℃ 3PE anti-corrosion steel pipe factory is formed by track roll, with normal high-frequency welding production. The front end of extrusion, cooling, sizing, flying saw cutting parts, etc. is equipped with loading circuit, and the rear end device is equipped with steel pipe frame. Butt weld is intensively heated in the pipe according to skin effect and proximity effect, so it can be quickly heated to the junction between crystals after the roll extrusion temperature required for welding The key material of steel pipe 3PE pipeline. Natural gas transmission pipeline is a special metallurgical product formed by deep processing. Due to the different process and technology, there are certain differences in the pipeline steel produced by various manufacturers. In the 1960s, X52 steel grade was adopted in the same way as X60 and X65 steel in the 70, and X70 steel was mainly used in the 80-90 period. Some foreign natural gas pipelines have begun to adopt X80
