Classification of anti-corrosion steel pipes for natural gas

1.IPN8710 anti-corrosion steel pipe. 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 applies to such cases.


2. FBE epoxy powder anti-corrosion steel pipe structure: The epoxy powder is coated on the surface of the steel pipe by an 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. The epoxy powder outer anti-corrosion layer has higher requirements for its impact resistance due to its small thickness; modifying the petroleum asphalt, increasing the service temperature of the asphalt anti-corrosion pipe, and enhancing the penetration resistance of deep-rooted plants is the best way to improve the impact resistance. An important approach to the performance of asphalt anti-corrosion coating.


4.3 PE anti-corrosion steel pipe 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 steel pipe 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 disbondment resistance, mechanical damage resistance
