Abstract
Provides is novel outer anticorrosion pipe. The utility model relates to the fields of oil, natural gas delivery pipes, and construction. The novel outer anticorrosion pipe comprises a working steel pipe, an epoxy powder coating, copolymer glue, and a polyethylene (PE) coated anticorrosive coating, wherein the epoxy powder coating is arranged on the outside of the working steel pipe. The copolymer glue is arranged on the outside of the epoxy powder coating, and the PE coated anticorrosive coating is arranged on the outside of the copolymer glue. The novel outer anticorrosion pipe is capable of effectively avoiding corrosion from outside to the working steel pipe in pipe network operational process and prolonging service life of the working steel pipe.
Description
Technical field:
The utility model relates to oil, natural-gas transfer pipeline and building field, is specifically related to the outer anti-corrosion pipe of a kind of novel 3PE.
Background technique:
Anti-corrosion pipe is mainly used in the pipework fields such as oil, chemical industry, rock gas, heating power, sewage treatment, water source, bridge, steel structure at home.According to the China's Statistical data, annual domestic pipe corrosion direct economic loss more than 2,800 hundred million, global annual invar pipe corrosion loss is up to 5,000 hundred million dollars at present.
The model utility content:
The purpose of this utility model provides a kind of novel outer anti-corrosion pipe, and it can effectively avoid the corrosion of pipe network operation process China and foreign countries bound pair working steel tube, has prolonged the working life of working steel tube.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises working steel tube 1, FBE 2, copolymer glue 3, PE and coats anticorrosive coat 4; FBE 2 is arranged on the outside of working steel tube 1, and copolymer glue 3 is arranged on the outside of FBE 2, and PE coats the outside that anticorrosive coat 4 is arranged on copolymer glue 3.
The utility model sets gradually FBE 2, copolymer glue 3 and PE by the outside at working steel tube 1 and coats anticorrosive coat 4, can effectively avoid the corrosion of pipe network operation process China and foreign countries bound pair working steel tube, has prolonged the working life of working steel tube.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises working steel tube 1, FBE 2, copolymer glue 3, PE and coats anticorrosive coat 4; FBE 2 is arranged on the outside of working steel tube 1, and copolymer glue 3 is arranged on the outside of FBE 2, and PE coats the outside that anticorrosive coat 4 is arranged on copolymer glue 3.
This embodiment sets gradually FBE 2, copolymer glue 3 and PE by the outside at working steel tube 1 and coats anticorrosive coat 4, can effectively avoid the corrosion of pipe network operation process China and foreign countries bound pair working steel tube, has prolonged the working life of working steel tube.
This embodiment fabrication processing is: working steel tube outer wall impeller blasting---on---outer wall cleaning---heating in medium frequency---electrostatic spraying epoxy powder---------cooling------lower pipe drive line---the naked head is repaired---Checking of finished products that electrical spark detects online that PE coats material and coats that copolymer glue coats of managing drive line.
This embodiment can effectively be avoided the corrosion of pipe network operation process China and foreign countries bound pair working steel tube, has prolonged the working life of working steel tube.
