Coated steel pipe


Anti-corrosion steel pipe
refers to use a special process to anti-corrosion treatment of ordinary steel pipe to make steel pipe with a certain degree of corrosion resistance. Generally used for waterproof, anti-rust, anti-acid oxidation and so on. Can effectively prevent or slow down the corrosion of steel pipe in the process of transportation and use of chemical or electrochemical reaction.

Depending on the needs of the steel pipe inner and outer walls corresponding to the anti-corrosion measures. Common are: coal tar epoxy, epoxy paint anticorrosive polyurethane coatings anticorrosive, IPN8710 drinking water pipe corrosion, non-toxic coating anti-corrosion polymer coatings anti-corrosion, pipe wall cement mortar, anticorrosion. The anti-corrosion steel pipe mainly used in the engineering field in the special requirements or harsh environments.

Anti-corrosion steel pipe base metal, including spiral, straight seam pipe, seamless pipe, widely used in petroleum, chemical, natural gas, heating, sewage treatment, water, bridges, steel structures, marine conveyance piling and other pipeline engineering in our country.

Anti-corrosion pipe classification
IPN8710 anti-corrosion
1, IPN8710 anticorrosive primer: polyurethane, polyethylene, modified epoxy resin, non-toxic anti-rust pigments and fillers, and additives such as composition, cured at room temperature the formation of interpenetrating networks, the coating structure is dense, acid, alkali, salt, anti-rust properties, strong adhesion, anti-corrosion primer coating for the inner wall of the water supply pipeline.
2, IPN8710 anti-corrosion coat: epoxy, rubber, resin-modified, non-toxic anti-rust pigments and fillers, additives, etc.. Excellent chemical resistance, non-toxic, the erosion of anti-microbial, anti-corrosion finish for water supply pipeline inner wall.

FBE epoxy powder anti-corrosion
FBE epoxy powder anticorrosion structure: electrostatic spraying epoxy powder coated steel pipe surface, a film. The coating coating operation is simple, non-polluting, coating impact resistance and flexural properties, temperature resistance advantages.

2PE/3PE anti-corrosion
Anticorrosive 2PE/3PE structure: electrostatic spray epoxy powder in the steel pipe surface and the lateral wound adhesive, lateral wound polyethylene coating, combined with three excellent performance, which significantly improves the overall quality of the anti-corrosion pipe. Resistant to chemical corrosion resistance to cathodic disbondment resistance to mechanical damage performance.

Coal tar epoxy
The structure of coal tar epoxy: epoxy + coal tar pitch + filler made of anti-corrosion coatings on steel pipe surface with glass cloth as strengthen the coating to form a coating, commonly used in the pipe wall corrosion. Thickness of 0.5 ~ 1.0mm.

High density polyethylene jacket anti-corrosion
High-density polyethylene jacket corrosion structure: steel pipe outside surface wrapped high-density polyethylene material with a high mechanical strength and excellent corrosion resistance, to protect the pipe due to external factors in the transportation, installation and during use to avoid damage. Manufacturing jacket tube should be added antioxidants, UV stabilizers and carbon black. Outer casing of polyethylene pipe and easy to aging, such as open storage to use the tarp material to cover, dumps should stay away from high heat and fire source, made of anticorrosive steel pipe to prohibit the exposure to sudden cold, otherwise the outer casing of polyethylene pipe easy to crack, affecting product performance and service life.
