Manufacturer of specialized anti-corrosion steel pipes for natural gas pipelines with reinforced 3PE anti-corrosion seamless steel pipes

Description :

　　The thickness of the external anti-corrosion layer is mainly determined by low and medium density polyethylene. Greatly improved the impact resistance of the 3PE anti-corrosion coating. The peeling strength and impact resistance indicators of the 3PE anti-corrosion layer have been significantly improved, and the mechanical strength and weather resistance of the 3PE anti-corrosion layer have been ensured by specifying the carbon black content of some special materials. 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) has also been increased. The company has established an insulation and anti-corrosion company with some anti-corrosion and insulation pipeline processing production lines, and hires senior engineers with high salaries to strictly control quality. Production of spiral steel pipes, anti-corrosion steel pipes, insulation steel pipes, polyurethane foam insulation steel pipes, steel sleeve steel buried insulation steel pipes, 3pe anti-corrosion steel pipes, epoxy coal tar anti-corrosion steel pipes, 8710 non-toxic water supply pipelines, cement mortar anti-corrosion steel pipes, buried steel pipes, petroleum and natural gas special anti-corrosion steel pipes, FBE epoxy powder anti-corrosion steel pipes, water supply and drainage anti-corrosion spiral steel pipes, heating and insulation steel pipes, sewage treatment anti-corrosion spiral steel pipes, seamless steel pipes, straight seam welded steel pipes and other businesses.

　　Our company currently has four spiral submerged arc welded pipe production lines for natural gas transmission 3PE anti-corrosion steel pipe manufacturers, all of which use advanced production equipment and Lincoln automatic submerged arc welding machines from the United States, and are equipped with online digital ultrasonic flaw detectors, hydrostatic testing machines, X-ray real-time imaging, and material testing machines. TPEP is an anti-corrosion structure that is the first generation of anti-corrosion forms applied to long-distance water pipelines. Compared with traditional 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 Guanghui Pipe Industry Group can be buried and used for 50 years according to national standards to ensure the normal use of the pipeline The composite process of TPEP anti-corrosion pipe base pipe and coating mainly involves preheating the base pipe to ensure that the surface temperature meets the temperature range required by the plastic powder, and then applying the plastic powder. Powder application, also known as dispersion method, can be divided into: spraying: using compressed air to spray plastic powder through a nozzle; Suction coating: Use a vacuum pump to create negative pressure inside the tube and suck in plastic powder; Immersion: Store plastic powder in a container and immerse the preheated base tube in the powder; Rolling molding: Plastic powder is stored on the wall of the base pipe, and the rotating rolling base pipe evenly distributes the powder. Due to the surface of the base pipe reaching a certain temperature, the plastic powder melts and coats the pipe wall, forming a coating and an anti-corrosion layer. 3PE anti-corrosion steel pipes are divided into ordinary 3PE anti-corrosion pipes and reinforced 3PE anti-corrosion pipes, with the main difference being the thickness of the anti-corrosion coating. Strengthening anti-corrosion measures will definitely result in superior anti-corrosion strength and performance. A layer of epoxy powder, a second layer of adhesive, and a third layer of polyethylene are integrated and firmly bonded with the steel pipe to form an excellent anti-corrosion layer. 3PE anti-corrosion steel pipe manufacturer for natural gas transmission

　　The main difference between 3PE and 2PE: 3PE anti-corrosion pipelines have an additional layer of epoxy powder, which has good corrosion resistance, mechanical properties, and strong resistance to cathodic stripping. Although it has the advantages of strict surface treatment, poor weather resistance, and high water absorption rate, it is suitable for buried submarine pipelines with a coating thickness of only 0.30.5 millimeters. 3PE anti-corrosion technology combines the excellent performance of epoxy coating and extruded polyethylene anti-corrosion layer, combining the interface characteristics and chemical resistance of epoxy coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion layer, thus significantly improving their respective performance. The characteristics of 3PE anti-corrosion pipeline include high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, and can be applied to media at 150 degrees Celsius, making it suitable for use in cold regions. Therefore, 3PE anti-corrosion coating is an ideal external protective layer for buried pipelines. 3PE anti-corrosion pipeline refers to the measure of coating 3 layers of polyethylene (3PE) on the outer wall of the pipeline/steel pipe to prevent or mitigate the corrosion and deterioration of the pipeline under the chemical and electrochemical action of the external medium or the metabolic activity of microorganisms in different working environments. 3PE anti-corrosion steel pipes have a service life of up to 50 years and are widely used in projects such as natural gas transportation, oil transportation, heating, and refrigeration. In its 1993 annual meeting paper, the American Society of Corrosion Engineers pointed out that "correctly applied anti-corrosion coatings should provide 99% of the protection requirements for buried components, while the remaining 1% is provided by cathodic protection," which illustrates the importance and irreplaceability of external protective coatings. Organic coating is one of the widely used protective technologies. At present, there are several commonly used external anti-corrosion coatings for steel pipeline protection, including petroleum asphalt anti-corrosion coating, epoxy coal tar coating, epoxy powder coating, coal tar enamel anti-corrosion coating, polyethylene adhesive tape anti-corrosion coating, polyethylene anti-corrosion coating, and 3PE anti-corrosion coating. The 3PE anti-corrosion coating has received high praise in the industry due to its excellent physical and mechanical properties, good chemical corrosion resistance, extremely low water and oxygen permeability, low environmental pollution, long anti-corrosion life, and high insulation performance.
