Classification of anti-corrosion steel pipes

When there are many types of corrosion media in steel pipes, such as acid, alkali, salt, oxidant and water vapor, the coating must be chemically inert, resistant to acid and alkali corrosion, and the coating film should have a dense structure, good waterproof permeability, strong adhesion, toughness and plumpness. In such cases, IPN8710 anti-corrosion applies.

IPN8710 Anti-corrosion primer: composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti-rust pigment filler, additives, etc., cured at room temperature to form an interpenetrating network, the coating film structure is dense, acid, alkali and salt resistant, has excellent anti-rust performance, strong adhesion, and is used for anti-corrosion priming coating of the inner wall of water supply pipelines.

IPN8710 anti-corrosion topcoat: composed of epoxy, rubber resin modification, non-toxic anti-rust pigment filler, additives, etc. Excellent chemical resistance, non-toxic, anti-microbial erosion, anti-corrosion topcoat for the inner wall of water supply lines.

FBE epoxy powder anti-corrosion FBE epoxy powder anti-corrosion structure: Electrostatic spraying process is used to apply epoxy powder on the surface of the steel pipe to form a film at one time. The coating has the advantages of easy application operation, no pollution, good impact and bending resistance of the coating, and high temperature resistance.

2PE/3PE anti-corrosion 2PE/3PE anti-corrosion structure: electrostatic spraying of epoxy powder on the surface of the steel pipe and side-winding adhesive and lateral winding of polyethylene anti-corrosion layer, combined with the excellent properties of the three, thus significantly improving the overall quality of the anti-corrosion pipe. It has chemical corrosion resistance, cathodic stripping resistance, and mechanical damage resistance.

Epoxy coal asphalt anti-corrosion Epoxy coal asphalt anti-corrosion structure: The anti-corrosion coating made of epoxy resin + coal tar asphalt + filler is coated with glass cloth on the surface of the steel pipe as a reinforcement to form an anti-corrosion layer, which is often used for anti-corrosion on the outer wall of the pipe. The thickness is generally 0.5~1.0mm.

High-density polyethylene jacket anti-corrosion anti-corrosion structure High-density polyethylene jacket anti-corrosion structure: Made of high-density polyethylene material wrapped on the outer surface of the steel pipe, it has extremely high mechanical strength and excellent corrosion resistance, which can protect the steel pipe from damage caused by external factors during transportation, installation and use.

Antioxidants, UV stabilizers and carbon black should be added to the manufacture of outer tubes. Polyethylene jacket pipe is easy to age, such as open storage should be covered with tarpaulin and other things, the stacking place should be away from high heat sources and fire sources, after making anti-corrosion steel pipes, it is forbidden to be exposed to the sun and sudden cooling, otherwise the polyethylene jacket pipe is easy to crack, affecting the performance and service life of the product.

Silicone high-temperature anti-corrosion silicone anti-corrosion layer, hard silicon calcium tile insulation layer, galvanized iron wire reinforcement layer, aluminum silicate fiber cloth waterproof layer, steel casing, and titanium-aluminum alloy powder on the inner surface of the steel casing. The silicone anti-corrosion layer is composed of silicone resin, ceramic powder, talc, mica powder, alumina powder and titanate coating curing material. It has anti-corrosion, thermal insulation, waterproof and external protection properties, and its silicone anti-corrosion layer can withstand a high temperature of 600 °C, and can be used for insulation pipelines that transport high-temperature media at 550 °C.
