Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical or electrochemical corrosion reaction of steel pipe.

Anti-corrosion steel pipe in the country is mainly used for petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields. Anti-corrosion steel pipe is divided into the following categories: IPN8710 corrosion, FBE epoxy powder corrosion, 2PE/3PE corrosion, Coal tar epoxy anticorrosive, High-density polyethylene jacket corrosion

The processing standard:

1.The petroleum natural gas uses three polyethylene (3PE) Steel pipe anticorrosion

Standard: SY/T0413-2002\DIN30670-1999

2. fluming water, oil, gas Medium and so on use two, three polypropylene (PP) anticorrosion

Standard: DEP 31.40.30.31

3. The petroleum natural gas uses FBE(Single-layer nodulizing epoxy powder anticorrosion) 2FBE(Double-decked nodulizing epoxy powder anticorrosion)

Standard: SY/T0315-2005；Q/CNPC38—2002

4. In the liquid epoxy coating guards against corrosion the steel pipe to be suitable for transportation crude oil, water, natural gas medium and so on

Standard: SY/T0457—2000

5. 8701 tap water antiseptic paint mainly uses in drinking the water conduct, the vessel, its hygienic target achieves tap water Q/12TG3663-2006

6. Epoxy coal tar winding glass cloth steel pipe anticorrosion

Standard: SY/T0447-96
