Steel Pipe Production Line: What are the processing methods of stainless steel welded pipe?

1.Cold drawing: It is easy to produce friction heat so that the pressure can be used, and the heat resistant high stainless steel tube should be used to remove the oil on the surface after forming.

2.Welding: Before welding, it should remove rust, oil, water, paint, etc. which are harmful to welding, and select the welding rod suitable for steel. The spot welding time distance is shorter than that of carbon steel spot welding. When the welding slag is removed, the stainless steel tube brush shall be used to prevent the local corrosion or strength from falling, and the surface shall be ground for grinding or cleaning.

3.Cutting and stamping: Because the stainless steel welded pipe is higher than general strength of materials, so it is more the need when punching and shearing stress, and a knife and knife gap accurately can not occur when the shear and work hardening, had better use plasma or laser cut off, when have to use gas cutting or arc cutting, grinding was carried out on the heat affected zone and the need for heat treatment.

4.Bending processing: Thin plate bending to 180, but in order to reduce the surface crack with twice the good radius size thickness, thick plate along the rolling direction to 2 times the radius of thickness, and rolling vertical bending to 4 times the thickness of the radius is necessary, especially at welding, in order to prevent cracking for welding area surface grinding machine.
