What are the details of thick-walled steel pipes before use
The welding method of thick-walled steel pipes should be selected according to the material and wall thickness of thick-walled steel pipes. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics. For example, tungsten arc ...Read more -
Comparison of advantages and disadvantages of spiral pipe and straight seam pipe weld
The weld seam of the spiral steel pipe is longer than that of the straight seam steel pipe. If the pipe length is L, the weld seam length is L/cos(θ). However, most of the defects of steel pipes are concentrated in the weld seam and the heat-affected zone. The long weld seam means that the probab...Read more
