1. IPN8710 anti-corrosion steel pipe: When there are many kinds of corrosive media in the steel pipe, such as acid, alkali, salt, oxidant, and water vapor, the coating must be chemically inert, resistant to acid, alkali, and salt corrosion, and the coating film should have a dense structure and waterproof permeability Good, strong adhesion, tough and plump. This kind of situation is suitable for IPN8710 anticorrosion.

2. FBE epoxy powder anti-corrosion structure: use an electrostatic spraying process to coat epoxy powder on the surface of the steel pipe to form a film at one time. The coating has the advantages of easy coating operation, good impact resistance and bending resistance, and high-temperature resistance.

3. Due to the small thickness of the epoxy powder outer anti-corrosion layer, the requirements for its impact resistance are higher; modifying petroleum asphalt, increasing the service temperature of the asphalt anti-corrosion pipe, and enhancing the penetration resistance of deep-rooted plants to improve An important way for the performance of asphalt anti-corrosion coating.

4.3PE anti-corrosion pipeline has strong sealing performance, and long-term operation can save a lot of energy, reduce energy costs and protect the environment.

5. 2PE/3PE anti-corrosion structure: Epoxy powder is electrostatically sprayed on the surface of the steel pipe, and the adhesive and polyethylene anti-corrosion layers are wound sideways. Combining the excellent properties of the three, the overall quality of the anti-corrosion pipeline is significantly improved. It has chemical resistance Corrosion, cathodic disbonding resistance, mechanical damage resistance
