Classification of anti-corrosion steel pipes for natural gas

1. IPN8710 anti-corrosion

When there are many types of corrosive media in the steel pipe, such as acid, alkali, salt, oxidant, and water vapor, the coating must be chemically inert and resistant to acid, alkali, and salt corrosion. The coating film should have a dense structure, good waterproof permeability, and strong adhesion. , Tough and plump. IPN8710 anti-corrosion is suitable for such cases.

2. FBE epoxy powder anti-corrosion structure: The epoxy powder is applied to the surface of the steel pipe by electrostatic spraying process, and a film is formed at one time. The coating has the advantages of simple coating operation, good impact resistance and bending resistance of the coating, and high-temperature resistance.

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

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

5.2PE/3PE anti-corrosion structure: the epoxy powder is electrostatically sprayed on the surface of the steel pipe, the adhesive is wound laterally, and the polyethylene anti-corrosion layer is wound laterally. Combined with the excellent properties of the three, the overall quality of the anti-corrosion pipeline is significantly improved. It has chemical resistance Corrosion, cathodic dis-bonding resistance, mechanical damage resistance
