Welded Stainless Steel Pipe Manufacturer in China
Welded stainless steel pipe is created by rolling a flat plate or sheet into a tube shape, which is then welded to give it its final form. Our welded stainless steel pipes can be customized, cut, and polished to meet your specific requirements. At Tuolian, we offer welded stainless steel pipes with plain end (PE), beveled end (BE), and threaded end (TE), ensuring a smooth surface for your various projects.

SS Welded Tube Examples of Application
Welded stainless steel pipe can be used in many industries such as petrochemical, pulp and paper-making, chemical, breweries, shipbuilding, automotive, coal, and energy sectors. Additionally, due to their corrosion resistance, they are widely used in food processing, water treatment facilities, and oil and gas processing.
Welded Stainless Steel Pipe Key Properties & Benefits
Our welded stainless steel pipes have excellent corrosion resistance, including resistance to pitting, crevice, and abrasion corrosion. They can be easily welded, mechanically processed, or bent to achieve a curved shape. Furthermore, welded stainless steel pipes maintain their strength at high temperatures. In terms of cost-effectiveness and ease of cleaning, they outperform other types of pipes.
Inspection & Quality Control
As a professional manufacturer with over 10 years of experience in the stainless steel industry, Tuolian boasts a highly trained and professional quality control team to oversee our manufacturing process. We have a comprehensive quality control procedure that includes chemical composition analysis, mechanical properties testing, hydraulic testing, metallographic testing, and non-destructive testing, including X-Ray flaw detection and dimensional checks.

Processing of welded Stainless steel pipe
- Bar & structural cutting: We offer OD and ID polishing options and provide round bars, square bars, hex & flat bars, angles, uneven leg angles, beams, and other shapes to choose from.
- Production cutting: We provide cutting services for product diameters up to 4″.
- Tubular polishing: Polishing stainless steel improves the physical appearance of the welded stainless steel tubes.
Welding Types of Stainless Steel Pipe
We offer a wide range of surface finishes for welded stainless steel pipes, including pickling, mirror, No. 1, No. 2D, No. 2B, (BA) Bright Anneal, No. 3, No. 4, No. 6, No. 7, No. 8, and other finishes to accommodate your specific requirements.
Compared to seamless stainless steel pipes, welded stainless steel pipes are more cost-effective and offer more consistent wall thickness. However, seamless stainless steel pipes are more suitable for critical applications due to their superior corrosion resistance and a more homogeneous grain structure.
