AI Technical Summary

Technical Problem

When existing straight-seater steel pipes are corroded or worn, the protective layer on the surface is prone to damage, and the wear resistance and rust resistance are poor, which cannot effectively reduce the impact of rust.

Method used

A corrosion-resistant seam steel pipe is designed, which consists of a steel pipe layer, an anti-rust layer, an anti-corrosion layer, an insulating layer and an wear-resistant layer. The anti-rust layer and the wear-resistant layer are composed of nickel-chromium alloy and ceramic particle coating respectively, and the anti-corrosion layer includes a polyisobutylene rubber layer, a tungsten steel layer and an epoxy resin layer. Through the combination of these layers, the overall wear and rust resistance and anti-rust properties of the steel pipe are enhanced.

Benefits of technology

By setting up a multi-layer protective structure, the wear resistance and rust resistance of seam steel pipes are significantly improved, the service life is extended, and the impact of chemical corrosion is reduced.

Abstract

The utility model relates to the technical field of seamed steel pipes, and provides a corrosion-resistant seamed steel pipe which comprises a steel pipe body, the steel pipe body is composed of a steel pipe layer, anti-rust layers, anti-corrosion layers, a heat insulation layer and a wear-resistant layer, the anti-rust layers are arranged on the inner side and the outer side of the steel pipe layer, the anti-corrosion layers are arranged on the sides, away from the steel pipe layer, of the anti-rust layers, and the heat insulation layer is arranged on the wear-resistant layer. The influence of chemical corrosion on the seamed steel pipe can be reduced through the anti-corrosion layer, the abrasive resistance is improved, the overall abrasion resistance of the seamed steel pipe is effectively improved, the corrosion resistance of the steel pipe can be improved through the arrangement of the isobutylene rubber layer, the problem that an existing straight seam steel pipe is poor in abrasion resistance is solved, and the service life of the straight seam steel pipe is prolonged. By arranging the anti-rust layer and the wear-resistant layer on the inner side and the outer side of the steel pipe layer, the anti-rust capability of the seamed steel pipe can be greatly improved, the steel pipe is prevented from being rusted, the service life of the steel pipe is prolonged, and the problem that an existing seamed steel pipe is poor in anti-rust performance is solved.
