3LPE COATED
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading steel pipe manufacturer and supplier
Three-Layer Polyethylene Coating (3LPE Coating) is an advanced anti-corrosion technology widely applied in the surface treatment of steel pipes to enhance their durability and corrosion resistance. The coating system consists of three distinct layers: an epoxy primer as the first layer, a copolymer adhesive as the second layer, and a polyethylene top layer as the outer protection, together forming a multi-layer composite protection system.
The primary advantage of 3LPE coating lies in its exceptional corrosion protection. The epoxy primer offers excellent adhesion and cathodic protection, effectively isolating the steel pipe from moisture and oxygen in the environment, thereby significantly reducing the risk of corrosion. The intermediate adhesive layer ensures a strong bond between the epoxy and polyethylene layers, while the polyethylene outer layer provides high mechanical strength and abrasion resistance, capable of withstanding external impact and physical damage. This ensures the integrity of the pipe during transportation, installation, and operation. Moreover, 3LPE coating exhibits outstanding chemical resistance and UV stability, making it suitable for harsh environments such as high temperatures, high humidity, and chemical exposure. It resists corrosion from a wide range of chemicals, including acids, alkalis, and salts, and is widely used in industries including oil and gas, chemical processing, municipal engineering, and submarine pipelines.
In terms of application, the 3LPE coating process is mature and efficient, suitable for large-scale industrial production. The uniform and consistent coating ensures reliable and long-term protection for each steel pipe, significantly extending service life and reducing long-term maintenance and replacement costs. With growing demands in energy and infrastructure construction, 3LPE coating has become the preferred anti-corrosion solution for long-distance pipelines, subsea pipelines, and pipelines conveying hazardous media.
