对钢管上的各类缺陷,传统的修复方法是紧贴钢管外壁直接焊接钢套管对缺陷进行补强,此操作困难且风险大,对弯管和外形不规则的管段则因难实施而只好更换。环氧钢壳复合套管完全解决了这些难题,且可有效地抑制内腐蚀过程的破坏,实现了不停输情况下钢管缺陷的免维护永久修复。环氧 For all kinds of defects on the steel pipe, the traditional repair method is to reinforce the defect by directly welding the steel casing against the outer wall of the steel pipe. This operation is difficult and risky. The pipe sections with irregular shapes and elbows are difficult to implement replace. Epoxy steel shell composite casing completely solve these problems, and can effectively inhibit the destruction of the internal corrosion process, to achieve non-stop maintenance of steel pipe defects without permanent repair.
