Technical standard for anticorrosive steel tubes
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 no...
