Base material: Typically made of Q235B or Q345B carbon steel, it complies with API 5L, ASTM A53, and other standards, offering excellent weldability and pressure-bearing capacity.

Spiral welding process: Produced using double-sided submerged arc welding (DSAW), the weld strength is higher than that of straight seam pipe, making it suitable for large-diameter pipe production.

3PE coating: Composed of an epoxy powder base layer, an adhesive middle layer, and a polyethylene outer layer, it is suitable for oil and gas pipelines and offers strong chemical resistance.

Epoxy resin coating: Such as IPN8710, it is used for water supply pipelines and is non-toxic and weather-resistant.

TPEP coating: Combining FBE and polyethylene, it provides both corrosion protection and mechanical protection.

ERW welding process: High-frequency resistance welding (HFAW) minimizes the heat-affected zone and offers strength similar to seamless pipe, making it suitable for large-diameter pipelines.

Epoxy coating technology: Fusion-bonded epoxy (FBE): Hot roller coating achieves uniform coating and offers high corrosion resistance, making it suitable for oil and natural gas pipelines.

Liquid epoxy spray coating: Smooth interior surfaces, suitable for water supply, drainage, and fire protection pipelines.

Coating Process:
Fusion Bonded Epoxy (FBE): Utilizes hot roll coating technology, suitable for large-diameter steel pipes (≥ 100mm). It offers strong adhesion, low porosity, and chemical resistance.
Liquid Epoxy Spray: Airless spraying achieves uniform coating on the interior surface, resulting in a smooth, efficient finish.
Composite Process: Some products utilize an "inner epoxy, outer polyethylene (3PE)" structure for enhanced corrosion resistance.

Galvanizing: Hot-dip galvanizing is a common process that creates a dense protective layer suitable for corrosive environments (such as oil and gas pipelines).

Epoxy coating: Often used in combination with galvanizing to enhance corrosion protection, it is particularly suitable for harsh environments such as chemical and marine applications.

Standards: Conforms to ASTM A53/A106, API 5L, and other standards. Some products are CE certified.

ASTM A106 Coated SSAW Tube is a seamless carbon steel pipe produced according to the ASTM A106 standard, processed using the SSAW process and then treated with an anti-corrosion coating.

SAW Process: Formed using SSAW, ensuring weld strength matches that of the parent material.

Coating: Common corrosion protection methods include 3LPE (three-layer polyethylene), galvanizing, plastic spraying, or anti-rust paint to enhance corrosion resistance.

Coated steel pipe is a composite pipe made from a steel pipe base, coated with a plastic or organic coating on both the inner and outer surfaces through processes such as spraying, roller coating, and dipping.

Plastic coatings: Common materials include polyethylene (PE) and epoxy resin (EP). These offer corrosion resistance and insulation properties, making them suitable for applications such as municipal pipeline corridors and power line wiring.

Organic coatings: These, such as epoxy powder coatings, are used for specialized gas transmission pipes, providing both corrosion resistance and structural strength.
