Keywords :What is the difference between the surface processing of spiral steel pipe and stainless steel pipe Update : 2023-03-30 View(s) : 1
The original surface of stainless steel pipe : NO.1 surface treated with heat treatment and pickling after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., the thickness is thicker from 2.0MM to 8.0MM. Blunt surface: NO.2D After heat tr...

The concept of stainless steel pipe : it is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when bending and torsional strength are the same, the weight is lighter, so it is also widely used i...
Keywords :Spiral steel pipes can be divided into several categories according to their uses Update : 2023-03-24 View(s) : 756
There are roughly four types of spiral steel pipes according to their uses: spiral steel pipes for drainage, spiral steel pipes for dredging, spiral steel pipes for piling, and spiral steel pipes for oil and gas. Spiral steel pipe for drainage Spiral steel pipe material for drainage: Q235...
Keywords :Heating requirements for spiral steel pipes Update : 2023-03-22 View(s) : 1
Before the steel is hot rolled, heating the raw material not only improves the plasticity of the metal, reduces the deformation force, but also facilitates rolling. In addition, during the heating process of steel, some structural defects and stress caused by Tao ingots can also be eliminated for st...
Keywords :Routine maintenance and production process of thick-walled straight seam steel pipe Update : 2023-03-20 View(s) : 849
The advantage of thick-walled straight seam steel pipe is that the online heat treatment process of the weld eliminates the welding stress, refines the metallographic grains of the heat-affected zone, and improves the physical and mechanical properties. Western developed countries attach great i...
