　　Anti corrosion steel pipes for water transportation

　　The main equipment for 3PE anti-corrosion steel pipes includes a steel pipe buffer platform, a pipe shifting unit, a traction machine, a pipe threading machinery, a high-pressure blasting machine, a repair platform, a transmission line, a steel pipe preheating furnace, a shot blasting machine main maintenance platform, a diverging grid steel pipe return transmission line, a fast in roller set, a fast out roller, and a maintenance platform. The anti-corrosion steel pipe anti-corrosion production line can be applied to single-layer FBE, double-layer FBE, double-layer PE, double-layer PP, and 3PE anti-corrosion operations of steel pipes. *The production line includes a steel pipe conveying system, surface treatment system, pipe dust removal system, steel pipe heating system, electrostatic spraying system, coating system, water cooling system, end cutting system, hydraulic and pneumatic system, detection system, and electrical control system, with a processing capacity of 350m2/h or more for small processing pipe diameter of Φ 104mm (4 ") and * processing pipe diameter of Φ 1600mm (63"). The 3PE anti-corrosion coating combines the high impermeability and mechanical properties of epoxy resin and polyethylene materials. So far, it is globally recognized as the most effective and high-performance anti-corrosion coating for steel pipes, which has been applied in many engineering projects.

　　The 3PE anti-corrosion steel pipe follows the standard, which mainly specifies polyethylene and high-density polyethylene, with a Vicat softening point set at not less than 110 ℃; The thickness of the external anti-corrosion layer is determined according to the German standard mainly composed of low and medium density polyethylene. Greatly improved the impact resistance of the 3PE anti-corrosion coating. The 3PE anti-corrosion coating specifies the mechanical strength and weather resistance of the 3PE anti-corrosion coating, and increases the frequency of testing the joint peeling strength.

　　3PE anti-corrosion pipelines are usually made up of components such as rolling forming, high-frequency welding, extrusion, cooling, sizing, and flying saw cutting during production. The front end of the unit is equipped with a storage sleeve, and the rear end of the unit is equipped with a steel pipe flipping frame. According to the yield effect and proximity effect, the butt weld generates a strong and concentrated thermal effect at the opening of the pipe blank, which can quickly heat up to the required welding temperature and achieve intergranular bonding after being squeezed by the pressure roller. 3PE anti-corrosion steel pipes have the characteristics of high circulation capacity and low engineering cost. The inner wall of the pipeline is lubricated, and there is relatively less scaling. The roughness ratio of the inner and outer surfaces of the PE pipe is definitely 1/20 of that of the steel pipe. Under the same diameter, length, and pressure, the flow of the PE pipe can be about 30% larger than that of the steel pipe, so the economic advantage is appropriately high.
