Product Introduction

Stainless Steel Welded Tube is to bend the tube billet (steel plate, steel strip) into the required cross-sectional shape, and then weld the weld. Welded pipe types include ERW, EFW, SAW, etc. Stainless steel welded pipe has excellent corrosion resistance and can resist corrosion from most chemicals. Welded stainless steel pipe production is flexible in size and can produce larger diameter pipes at low cost. Our company is a stainless steel pipe supplier with 15+ export experience.

Welded Stainless Steel Pipe Production Process

Stainless steel welded pipe is made by rolling stainless steel strip or sheet into a tube and then welding it longitudinally. Welded pipes can be completed by hot forming and cold forming processes. The weld can leave a weld bead, or it can be further processed by cold rolling, forging and other methods.
