Problems solved by technology

[0002] Steel pipes are widely used as building materials and building materials. Ordinary steel pipes have poor acid and corrosion resistance, and are easily corroded when used in harsh environments. Moreover, ordinary steel pipes do not have insulation. When used for pipeline transportation of gas and natural gas, they are easy to cause safety hazard
In addition, traditional steel pipes are basically circular tubular structures, which cannot meet the needs of all aspects of use.

Embodiment Construction

[0011] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0012] Such as figure 1 The anti-corrosion insulated steel pipe shown includes a steel pipe body 1, a plurality of arc-shaped convex lines 2 are evenly distributed on the inner wall of the steel pipe body 1, and an epoxy oil-resistant anti-corrosion layer 3 is coated on the outer wall of the steel pipe body 1, and the epoxy oil-resistant anti-corrosion layer The surface of layer 3 is wrapped with insulating layer 4 . The thickness of the epoxy oil-resistant and anti-corrosion layer 3 is 0.2 mm to 0.5 mm, and the thickness of the insulating layer 4 is 0.3 mm to 0.6 mm. Wherein, the number of convex strips 2 is six.

[0013] Inspired by the above-mentioned id...

Abstract

The invention relates to the technical field of metal pipes, in particular to an anti-corrosion insulating steel pipe which comprises a steel pipe body. Multiple arc protruding bars are annularly and evenly distributed on the inner wall of the steel pipe body, the outer wall of the steel pipe body is coated with an epoxy oil-resistant corrosion-resistant layer, and an insulating layer is wound on the surface of the epoxy oil-resistant corrosion-resistant layer. The anti-corrosion insulating steel pipe is novel in structure and meets diversified market requirements, the surface of the steel pipe is coated with the corrosion-resistant layer, so that the corrosion resistance of the metal pipe is effectively enhanced, the insulating layer has an insulating effect, and the anti-corrosion insulating steel pipe is safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of metal pipes, in particular to an anti-corrosion insulating steel pipe. Background technique [0002] Steel pipes are widely used as building materials and building materials. Ordinary steel pipes have poor acid and corrosion resistance, and are easily corroded when used in harsh environments. Moreover, ordinary steel pipes do not have insulation. When used for gas and natural gas pipelines, they are easy to cause a safety hazard. In addition, traditional steel pipes are basically circular tubular structures, which cannot meet the needs of various uses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-corrosion insulated steel pipe in order to overcome the above existing problems. [0004] The technical solution adopted by the present invention to solve the technical problem is: an anti-corrosion insulated steel pipe, including a steel...
