Quotation for three-layer polyethylene anti-corrosion steel pipe

Description :

　　What is the connection between polyethylene and PE? Is 3-layer polyethylene equivalent to 3PE? Stepped rack and pinion cooling bed: The bed surface of the stepped rack and pinion cooling bed consists of two sets of racks, one assembled on a fixed beam, called a static rack, and the other assembled on a moving beam, called a moving rack. When the lifting mechanism is activated, the moving rack rises to lift the steel pipe. Due to its inclined angle, the steel pipe rolls along the tooth profile once when lifted. After the moving gear rises to the * position, the stepper mechanism moves to advance the moving gear towards the output direction of the cooling bed by one step. The lifting mechanism continues to move, driving the moving rack to descend and place the steel pipe into the fixed rack groove. The steel pipe rolls again along the tooth profile of the fixed rack, and then the moving rack returns to its initial position, completing a work cycle. Screw cooling bed: The screw cooling system consists of a main transmission device, screws, and a fixed cooling platform. The screws include a screw core and a screw helix. The working surface of the fixed cooling platform is higher than the spiral rod core and lower than the spiral line, and the weight of the steel pipe body is borne by the fixed cooling platform.

　　The main transmission device drives the screw to rotate synchronously, and the spiral line on the screw pushes the steel pipe to roll forward on the fixed cooling platform for cooling. 3PE anti-corrosion pipe is suitable for underground water supply and drainage, underground grouting, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue and return water transportation pipeline. The applicability of water supply pipelines for anti spray and sprinkler systems. Cable protection sleeves for power, communication, highways, etc. Suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines, chemical engineering, and printing and dyeing. Anti corrosion engineering for sewage treatment discharge pipes, sewage pipes, and biological tanks. For agricultural irrigation pipes, deep well pipes, drainage pipes and other network applications, it can be said that 3PE anti-corrosion steel pipes are essential in current construction, and we believe that with the extension of technology, they will have even more brilliant achievements in the future.

　　The three-layer structure polyethylene anti-corrosion layer (3PE) combines the excellent properties of fusion bonded epoxy powder coating and extruded polyethylene anti-corrosion layer. It combines the interface characteristics and chemical resistance of fusion bonded epoxy powder coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion layer, thereby significantly improving their respective performance. Therefore, as an external protective layer for buried pipelines, it is very superior. According to relevant information, three-layer PE can extend the service life of buried pipelines to 50 years, and is currently considered an advanced external anti-corrosion technology for pipelines internationally. In China, three-layer PE has been first applied in the oil and gas system. The Shaanxi Beijing natural gas pipeline and Kushan oil pipeline that have been built in China, as well as the nearly 4000 kilometers of West East Gas Pipeline, which is a national key project, have all adopted a three-layer PE external anti-corrosion coating. In Tianjin, the 67 kilometer high-pressure pipeline from Shaanxi to Tianjin, the 30 kilometer high-pressure natural gas pipeline from the outer ring line, and the 122 kilometer underground gas storage pipeline from Shaanxi to Beijing also use three-layer PE. It has become the development direction of external anti-corrosion coatings for pipelines in the future!

　　Processing methods: There are generally two types of 3pe anti-corrosion steel pipes: winding type and round mold wrapping type. The base materials include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water vapor permeability resistance, and mechanical properties. The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some may not corrode after being buried underground for decades, while others may leak within a few years. It's because they use different external anti-corrosion coatings. The process fully utilizes the excellent anti-corrosion performance of high-temperature fusion bonded epoxy powder, and can be sprayed mechanically. The cost of the added anti-corrosion tape is also relatively low. Since its formation, the externally wrapped anti-corrosion tape can serve as the external protective structure of the coating, effectively eliminating the defects of thin thickness, easy detachment and collision of the double-layer epoxy powder coating, and the failure of the anti-corrosion layer. In practical operation, the three materials are mixed and integrated into one, and processed to firmly bond with the steel pipe to form an excellent anti-corrosion layer.
