Cangzhou Guanghui Pipe Industry, a manufacturer of reinforced wrapped 3pe anti-corrosion steel pipes

Description :

　　Currently, 3PE anti-corrosion has successfully solved the problems of corrosion resistance and collision resistance on the outer wall of steel pipes. However, in China, liquid epoxy coating IPN8710 is commonly used for inner wall anti-corrosion, which takes a long time to cure at room temperature. Moreover, the use of liquid epoxy coating on the inner wall can only reduce drag and cannot achieve corrosion and erosion resistance. If used in water pipelines, the inner wall must be made of hot-melt epoxy resin powder to better improve its corrosion resistance and friction resistance. Among them, the external 3PE and internal fusion bonded epoxy composite steel pipe used in the Henan section of the South to North Water Diversion Middle Route has been successfully applied to the supporting facilities of the South to North Water Diversion Project. Solved the characteristics of less scaling, smoothness, wear and corrosion resistance on the inner wall.

　　3PE anti-corrosion steel pipe implementation standard: SY/T0413-2002 standard is implemented domestically, which came into effect on August 1, 2002. The standard 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 DIN30670-1991, which mainly uses low and medium density polyethylene. Ji Dadi has increased the Kang impact strength of the 3PE anti-corrosion layer. SY/T0413-2002 significantly increases the peel strength and Kang impact indicators of the 3PE anti-corrosion layer, and specifies that based on the carbon black content of some special materials, the mechanical strength and weather resistance of the 3PE anti-corrosion layer are ensured, and the sampling frequency of the joint peeling strength (i.e. the peeling strength of the heat shrink sleeve and heat shrink tape to the primer steel) is increased.

　　The use of 3PE anti-corrosion steel pipe: Many people only know one thing about the use of 3PE anti-corrosion steel pipe, but they don't know the other. Its function is really wide coverage, and it is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue and return water transportation pipeline. The water supply pipelines for anti spray and sprinkler systems have greater applicability. 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 pharmaceuticals, 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.

　　3PE anti-corrosion steel pipe equipment: The main equipment for producing 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 host 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 processing pipe diameter is Φ 89mm, the processing pipe diameter is Φ 3020mm, and the processing capacity is above 350m2/h. This production line includes steel pipe transmission 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.

　　Advantages of 3PE anti-corrosion steel pipe: Ordinary steel pipes will experience severe corrosion in harsh environments, which will reduce the service life of the steel pipe. The service life of anti-corrosion and insulation steel pipes is also relatively long, usually around 30-50 years. Proper installation and use can also reduce the maintenance cost of the pipeline network. Anti corrosion and insulation steel pipes can also be equipped with an alarm system to automatically detect pipeline leakage faults, accurately identify the fault location, and automatically sound an alarm. According to relevant information, the service life of natural gas anti-corrosion seamless pipes reaches 50 years, and currently it is considered as external anti-corrosion for pipelines. Since the emergence of 3PE decomposition data in the 1930s, three-layer polyethylene PE anti-corrosion steel pipes have been rapidly developed as a superior thermal anti-corrosion material. Their application scope has become increasingly common, and they are widely used in various engineering projects due to their complex construction and clear energy-saving and anti-corrosion effects.
