Analysis of Corrosion Causes of Steel Pipes

Keywords :Analysis of Corrosion Causes of Steel Pipes        Update : 2022-03-28        View(s) : 829

Corrosion of steel pipes is mainly divided into two categories: internal corrosion and external corrosion. External corrosion is mainly due to the corrosion caused by the connection between the pipeline material and the external environment such as soil, seawater, atmosphere, and other corr...

Comparison of advantages and disadvantages of spiral steel pipe and straight seam steel pipe welding

Comparison of advantages and disadvantages of spiral steel pipe and straight seam steel pipe welding

Keywords :Comparison of advantages and disadvantages of spiral steel pipe and straight seam steel pipe welding        Update : 2022-03-25        View(s) : 1130

The welding seam of the spiral steel pipe is longer than that of the straight seam steel pipe . If the pipe length is L, the welding seam length is L/cos(θ). The vast majority of steel pipe defects are concentrated in the weld and heat-affected zone. The long weld means that the probability of ...

What is the difference between the surface processing of spiral steel pipe and stainless steel pipe

What is the difference between the surface processing of spiral steel pipe and stainless steel pipe

Keywords :What is the difference between the surface processing of spiral steel pipe and stainless steel pipe        Update : 2022-03-22        View(s) : 967

Let's first talk about the original surface of the stainless steel tube: NO.1 The surface that is subjected to heat treatment and pickling after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., the thickness is thicker from 2.0MM-8.0MM. Dull...
