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
The present invention relates to a kind of technical field of steel pipe, especially a kind of anti-corrosive steel tube.
Background technique
Original steel pipe is to form by processing and perforation to pole, and the anti-corrosion protection Performance Ratio of steel pipe is relatively poor, and Safety performance is low, has shortened the working life of steel pipe.
Summary of the invention
In order to overcome the deficiency that original steel pipe corrosion-proof protective value is poor, Safety performance is low and working life is short, the invention provides a kind of anti-corrosive steel tube.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-corrosive steel tube, comprise outer wall, zinc-riched epoxy powder coating, inwall and polyethylene powders coating, and with the zinc-riched epoxy powder coating, have the polyethylene powders coating on inwall on outer wall.
According to another embodiment of the invention, comprise that further the polyethylene powders coating is with copper coating.
The invention has the beneficial effects as follows: this anti-corrosive steel tube is simple in structure, and is easy to use, practical; have excellent anti-corrosion protection ability, can stop the infiltration that even cuts off aggressive medium, increased the Safety performance of steel pipe; extended the working life of steel pipe, be easy to apply.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
1. outer walls in figure, 2. zinc-riched epoxy powder coating, 3. inwall, 4. polyethylene powders coating, 5. copper coating.
Embodiment
Structural representation of the present invention as Fig. 1, this anti-corrosive steel tube comprises outer wall 1, zinc-riched epoxy powder coating 2, inwall 3, polyethylene powders coating 4 and copper coating 5, has zinc-riched epoxy powder coating 2 on outer wall 1, with polyethylene powders coating 4, has copper coating 5 on polyethylene powders coating 4 on inwall 3.
During use, the mode of outer wall of steel pipe 1 employing friction spraying on outer wall 1, then adopts the flame spraying mode that polyethylene powders is sprayed on inwall 3, then the plated with copper layer zinc-riched epoxy powder spray.This anti-corrosive steel tube is simple in structure, and is easy to use, practical, has excellent anti-corrosion protection ability, can stop the infiltration that even cuts off aggressive medium, increased the Safety performance of steel pipe, extended the working life of steel pipe, is easy to apply.
