Description
Coated steel pipe is a kind of pipe with wide application prospect and economic value. Its characteristics of corrosion resistance, corrosion resistance, pressure resistance and long service life make it one of the ideal materials in various fields.Our company can produce and supply various specifications of pipes, anti-corrosion steel pipes, coated steel pipes, plastic-coated steel pipes, etc., with sufficient inventory.
Product Description
Coated steel pipes are steel-plastic composite steel pipes that use steel pipes as the base and are welded with a plastic anti-corrosion layer on the inner surface of the steel pipe (bottom pipe) through spraying, rolling, dipping and suction processes or a plastic anti-corrosion layer is welded on the inner and outer surfaces. Therefore, coated steel pipes Also called plastic-coated steel pipes, anti-corrosion steel pipes, coated steel pipes have excellent corrosion resistance and relatively small friction resistance.
Anti-corrosion classification of inner wall of anti-corrosion steel pipe
1. Liquid epoxy coating IPN8710 anti-corrosion
2. Sintered epoxy powder anti-corrosion
Classification of outer wall anti-corrosion of coated steel pipes
1. 3PE anti-corrosion
2. 2PE anti-corrosion steel pipe
3. Single layer PE anti-corrosion steel pipe
4. Epoxy coal pitch anti-corrosion
5. Anti-corrosion of high-density polyethylene sheath
Anti-corrosion steel pipe anti-corrosion standards
FBE epoxy powder anti-corrosion implements SY/T0315-2005 “Technical Specifications for Single-layer Fusion-bonded Epoxy Powder Outer Coating for Steel Pipes”
2PE/3PE anti-corrosion implements GB/T23257-2009 “Technical Standard for Polyethylene Outer Coating of Buried Steel Pipes”
Anti-corrosion surface layer rust removal standards: The outer surface of the steel pipe shall be sandblasted and rust removed to Sa2 1/2 level according to the requirements of GB/T8923-2008, and the depth of the anchor pattern on the surface of the steel pipe shall be 40-100 μm.
Anti-corrosion steel pipe base materials include spiral pipes, straight seam pipes, seamless pipes, etc., which are widely used in pipeline engineering fields such as long-distance water transportation, petroleum, chemical industry, natural gas, heat, sewage treatment, water sources, bridges, steel structures, marine water transportation piling, etc. .
