It is an efficient method to make the epoxy powder of inside and outside the steel pipe for anti-corrosion. The anti corrosive steel pipe has many advantages, such as strong corrosion resistance of the coating, which can resist the erosion of a variety of chemical mediator; The coating surface is smooth and the friction resistance is small. This steel pipe of anti corrosion is widely used in petroleum, natural gas transmission pipelines, water supply and drainage pipelines and many other fields.

√ Superior Protection - Resists chemicals, moisture, and extreme temperatures.
√ High Efficiency - Smooth, low-friction coating improves flow efficiency; max output 8 km/day (varies by diameter).
√ Eco-Friendly - 98% powder recovery rate reduces waste and costs.
√ Full Automation - Integrated heating, spraying, and cooling for uniform coverage.
√ Global Compliance - Meets ISO 21809-2, DIN 30673, SY/T0413, GB/T23257, and more.

Surface Prep: Shot blasting (SA2.5) for optimal adhesion.

Heating: Induction heating to precise temperature.

Coating: Electrostatic FBE powder spraying (internal/external).

Curing & Cooling: Uniform curing for durable finish.
