Liquid Epoxy Coated Interior & Epoxy Coal
Tar Exterior Composite Steel Pipe for Water Supply
Product Introduction:
The Liquid Epoxy Coated Interior & Epoxy Coal Tar Exterior Composite Steel Pipe for Water Supply is a composite steel pipe that uses straight seam welded pipe, seamless pipe, or spiral welded pipe as the base. The inner wall is coated with liquid epoxy resin, while the outer wall is coated with epoxy coal tar. This dual-coating system forms protective layers inside and outside the pipe, making it ideal for applications in municipal water mains, buried pipelines, and large-diameter water or sewage transmission systems.
Product Features:
- High Sanitary Safety: The liquid epoxy resin used for the inner coating complies with national drinking water hygiene standards. Its smooth surface helps reduce scale buildup and inhibits microbial growth, making it especially suitable for the transportation of potable water.
- Excellent Corrosion Resistance: The epoxy coal tar outer coating effectively resists chemical substances such as acids, alkalis, and salts commonly found in soil. It is ideal for buried pipelines and significantly extends service life while reducing long-term maintenance costs.
- Good Weather Resistance: For above-ground pipelines, the epoxy coal tar coating offers a degree of UV and weather resistance. It withstands sunlight, rain, and temperature fluctuations, maintaining the integrity and protective performance of the pipeline in outdoor environments.
Product Applications:
- Municipal Water Supply Projects: Suitable for the renovation and upgrading of urban water supply systems. The dual-layer anti-corrosion structure enhances system reliability and ensures water quality.
- Industrial Water Supply Systems: Widely used in industries such as chemical, pharmaceutical, and electronics, where there are strict requirements for water quality and corrosion resistance. The inner epoxy layer ensures clean water delivery, while the outer coating protects against external chemical corrosion.
- Building Water Supply and Drainage Systems: Applicable for use in high-rise or underground building water pipelines. The inner liquid epoxy layer ensures compliance with hygiene standards, while the outer epoxy coal tar coating adapts to various environmental conditions, providing durable external protection.
