In complex industrial and civil fields, plastic-coated steel pipes have become the leader in many pipeline systems with their unique anti-corrosion, wear-resistant, and weather-resistant properties. So, what is the outer coating of plastic-coated steel pipes that can protect steel pipes from externa

Welded pipes for oil and gas transportation are mostly produced using multi-wire submerged arc welding technology. For welded pipe manufacturing companies, first of all, it is necessary to ensure that the various mechanical properties of the welded pipe meet the requirements. On the other hand, it i

The energy-saving potential of heat treatment is very large. How to take measures to strengthen energy saving is an important issue facing every heat treatment worker. The following is a brief discussion on energy saving in heat treatment processes.First, reduce the heating temperature.Generally, th

Decarburization is the phenomenon in which the carbon content on the surface of a steel pipe decreases during heat treatment. The essence of decarburization is that the carbon atoms in the steel pipe react with the furnace atmosphere such as hydrogen or oxygen at high temperatures to generate methan
