Along with the years of entrepreneurial journey of Zhongyuan people, she gradually formed her own spiritual pillar and behavioral norms. In the silent inheritance, she guided Zhongyuan Company towards a more brilliant tomorrow.
The steel plastic composite structure anti-corrosion steel pipe is composed of a steel base pipe and an inner and outer plastic anti-corrosion layer, combining the high mechanical strength of steel and the corrosion resistance of plastic. The inner layer is usually coated with epoxy resin or polyethylene, and the outer layer is made of materials such as polyethylene and epoxy powder according to the needs, forming a multi-layer protective structure. This design effectively isolates chemical corrosion, soil erosion, and microbial growth, while reducing fluid resistance and extending usage time.

Composition and characteristics of anti-corrosion steel pipes for steel plastic composite structures
The steel plastic composite structure anti-corrosion steel pipe is composed of a steel base pipe and an inner and outer plastic anti-corrosion layer, combining the high mechanical strength of steel and the corrosion resistance of plastic. The inner layer is usually coated with epoxy resin or polyethylene, and the outer layer is made of materials such as polyethylene and epoxy powder according to the needs, forming a multi-layer protective structure. This design effectively isolates chemical corrosion, soil erosion, and microbial growth, while reducing fluid resistance and extending usage time.
Manufacturing process and technological advantages
The manufacturing process of steel plastic composite pipes includes steps such as preheating of steel pipes, spraying of inner and outer coatings, and high-temperature curing. For example, the inner oxygen and outer polyethylene anti-corrosion steel pipe needs to be coated with epoxy resin on the inner wall first, and then the polyethylene layer is compounded by hot melt technology to form a sturdy anti-corrosion structure. This process improves the adhesion and wear resistance of the coating, and supports customized production, such as using seamless steel pipe substrates in high-pressure environments and spiral steel pipes or straight seam welded pipes in low-pressure environments. Its technological advantages are reflected in acid and alkali corrosion resistance, UV aging resistance, good electrical insulation, and adaptability to temperature ranges from -30 ℃ to 120 ℃.
Application Fields and Scenarios
Steel plastic composite pipes are widely used in fields such as fire sprinkler systems, chemical fluid transportation, urban water supply and drainage, cable protection, and oil and gas transportation. In the fire protection system, the epoxy resin inner wall can prevent scaling and ensure smooth water flow; In the chemical industry, the characteristics of highly corrosive media ensure pipeline safety; In underground environments, polyethylene outer coatings can resist soil and microbial erosion. In addition, its lightweight and diverse connection methods (such as flanges and clamps) are also suitable for complex environments such as mine ventilation and marine engineering.
Performance parameters and standard specifications
The coating thickness of steel plastic composite pipes is usually 100-500 microns (mainly 350 microns), which meets industry standards such as CJT120-2000. The product models include GS-X-SP-T-EP (fire protection), GS-D-SP-T-EP (cable protection), etc., with diameters ranging from DN15 to DN3600 and lengths supporting customization from 6 meters to 12 meters. Its hygiene performance has been certified by food grade epoxy powder, suitable for drinking water transportation, and its friction coefficient is 30%~50% lower than that of ordinary steel pipes, significantly improving transportation efficiency.
