Embodiment Construction

[0010] Such as figure 1 It is a structural schematic diagram of the present invention. The anti-corrosion steel pipe includes an outer wall 1, a zinc-rich epoxy powder coating 2, an inner wall 3, a polyethylene powder coating 4 and a copper coating 5, and the outer wall 1 is attached with a zinc-rich epoxy powder coating 2 , the inner wall 3 is attached with a polyethylene powder coating 4, and the polyethylene powder coating 4 is attached with a copper plating layer 5.

[0011] When in use, the outer wall 1 of the steel pipe is sprayed with zinc-rich epoxy powder on the outer wall 1 by means of friction spraying, and then polyethylene powder is sprayed on the inner wall 3 by flame spraying, and then coated with a copper layer. This anti-corrosion steel pipe is simple in structure, easy to use, strong in practicability, has excellent anti-corrosion protection ability, can prevent or even block the penetration of corrosive media, increases the safety performance of the steel pi...

Abstract

The invention relates to the technical field of steel pipes and particularly relates to an anti-corrosion steel pipe. The anti-corrosion steel pipe comprises an outer wall, wherein a zinc-rich epoxy powder coating layer, an inner wall and a polyethylene powder coating layer, the zinc-rich epoxy powder coating layer is attached to the outer wall, the polyethylene powder coating layer is attached to the inner wall, and a plated copper coating layer is attached to the polyethylene powder coating layer. The anti-corrosion steel pipe is simple in structure, convenient to use, strong in practicability, excellent in anti-corrosion protecting ability and capable of stopping even isolating permeability of corrosive mediums, increases the safety performance of the steel pipe and prolongs the service life of the steel pipe, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of steel pipes, in particular to an anti-corrosion steel pipe. Background technique [0002] The original steel pipe is formed by processing and piercing the round bar, the corrosion protection performance of the steel pipe is relatively poor, the safety performance is low, and the service life of the steel pipe is shortened. Contents of the invention [0003] In order to overcome the deficiencies of poor anticorrosion protection performance, low safety performance and short service life of the original steel pipe, the invention provides an anticorrosion steel pipe. [0004] The technical solution adopted by the present invention to solve the technical problem is: a kind of anti-corrosion steel pipe, including the outer wall, zinc-rich epoxy powder coating, inner wall and polyethylene powder coating, the outer wall is attached with zinc-rich epoxy powder coating, the inner wall Comes with a polyethylene p...
