Buried 3pe anti-corrosion steel pipe natural gas pipeline 3pe anti-corrosion seamless steel pipe manufacturer

Description :

　　The 3PE anti-corrosion (three-layer polyethylene) process is an advanced anti-corrosion technology introduced from abroad in the late 1990s. Its full name is fusion bonded epoxy/extruded polyethylene structural protective layer. 3PE anti-corrosion technology combines the excellent performance of epoxy coating and extruded polyethylene anti-corrosion layer, and combines the interface characteristics and chemical resistance of epoxy coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion layer, thereby significantly improving their respective performance. Its characteristics 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. According to authoritative testing, buried pipelines using 3PE anti-corrosion technology can have a lifespan of up to 50 years.

　　The processing methods for 3PE anti-corrosion steel pipes are generally divided into two types: winding and circular mold wrapping. The three-layer structure polyethylene anti-corrosion coating (3PE) combines the excellent properties of fusion bonded epoxy powder coating and extruded polyethylene anti-corrosion coating. It combines the interface characteristics and chemical resistance of fusion bonded epoxy powder coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion coating, 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. The current development status of 3PE anti-corrosion steel pipe and 3PE anti-corrosion spiral steel pipe industry in China is still good. In the anti-corrosion industry, the well-known 3PE anti-corrosion steel pipe also plays a significant role. Today, we will analyze and introduce the relevant knowledge of 3PE anti-corrosion steel pipe, hoping to be helpful for those who are not yet familiar with its functions in the industry. The base materials of 3PE anti-corrosion steel pipe include seamless steel pipe, spiral steel pipe and straight seam steel pipe. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water and gas 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.

　　3PE anti-corrosion steel pipe is suitable for high-rise building water supply, heating network, water engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines 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, 3PE anti-corrosion steel pipes are essential in current construction. We believe that with the extension of technology, they will have even more brilliant achievements in the future. In terms of use, protective technology should be used to prevent pipelines from being corroded by soil, air and transport media (such as oil, natural gas, etc.). The pipelines that transport oil and gas are mostly located in complex soil environments, and the media they transport are often corrosive, so both the inner and outer walls of the pipelines may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which not only interrupts transportation, but also pollutes the environment and may even cause fires, posing a hazard. Introduction of anti-corrosion steel pipe manufacturers: Relevant institutions analyze that the growth rate has accelerated on a macro level recently, and the production of crude steel and anti-corrosion steel pipes has significantly rebounded, indicating that the overall supply and demand relationship in the domestic anti-corrosion steel pipe market is improving. However, after an accelerated rise in the price of anti-corrosion steel pipes, low-priced resources have gathered in the market, and the previously leading prices of coking coal and coke have begun to adjust, which will have a certain impact on market sentiment.
