There are many reasons for steel pipeline leakage, which can be mainly divided into three categories: corrosion perforation, fatigue cracking, and external force damage.Although corrosion control measures can substantially slow corrosion, it does not prevent it. When the cathodic protection is insuf

High-frequency welded steel management properties: normal temperature mechanical properties, high-temperature mechanical properties, low-temperature properties, corrosion resistance. The physical and chemical properties of high-frequency welded steel pipe mainly depend on the chemical composition of

The pressure ratio of the spiral steel pipe on the gas pipeline also tends to decrease gradually. For pipe diameter, pressure, and pressure ratio, optimization calculation and comparison are required. When the output is determined and the pipe diameter, pressure, and pressure ratio are determined th

The anti-corrosion layer of the steel pipeline should have the following properties:(1) Effective electrical insulation.(2) Good moisture and water resistance.(3) It has strong mechanical strength.(4) The anti-corrosion layer has good adhesion to the steel surface.(5) The material and construction p
