Buried epoxy coal tar anti-corrosion steel pipe

Buried Epoxy Coal Tar Anti-Corrosion Steel Pipe

Product Overview:
The buried epoxy coal tar anti-corrosion steel pipe is engineered to deliver long-lasting protection in underground environments. It features a high-performance coating made from a blend of epoxy resin and coal tar pitch, offering excellent resistance to chemical corrosion, moisture, and mechanical damage. This type of pipe is widely used in municipal, industrial, and infrastructure projects requiring reliable buried pipeline solutions.

Key Features:
The epoxy coal tar coating forms a dense, tough, and waterproof protective layer on the pipe surface. It adheres strongly to the steel, effectively isolating it from corrosive soil, groundwater, and other environmental factors. The coating also resists microbial corrosion and physical abrasion, ensuring long-term structural integrity of the buried pipeline.

Mechanical and Physical Properties:
The steel pipe offers high strength, pressure resistance, and weldability, while the epoxy coal tar coating contributes superior chemical resistance and mechanical durability. This combination makes the pipe suitable for harsh underground conditions, including saline-alkali soils, sewage environments, and fluctuating groundwater levels.

Applications:

• Underground water supply and drainage pipelines

• Sewage and wastewater treatment systems

• Industrial and petrochemical fluid transport

• Cooling water lines and hydropower installations

• Gas and oil transmission lines requiring buried corrosion protection

Advantages:

• Excellent anti-corrosion performance in buried conditions

• Strong adhesion and long-lasting protective coating

• Resistant to chemical attack, soil corrosion, and microbial erosion

• Reduces maintenance costs and extends pipeline lifespan

• Suitable for high-humidity and chemically aggressive environments

• Conforms to GB, SY/T, and other relevant anti-corrosion standards

Quality Assurance:
Each pipe undergoes thorough surface preparation (usually sandblasting to Sa2.5 level), followed by uniform coating application and curing. Quality inspections include coating thickness testing, adhesion strength measurement, and holiday detection to ensure reliable performance in the field.
