Stainless Steel Welded Pipe & Tube

How is stainless steel welded pipe manufactured?

Stainless steel welded pipe is formed by rolling flat strip into a tube and joining the seam by TIG (GTAW) or laser welding, followed by annealing and bright-annealing for a clean, uniform finish. TeCarve sources from partner factories using automated TIG welding for consistent seam integrity across all production runs.

What grades are available for welded stainless steel pipe?

We supply welded stainless steel pipe in grades 201, 202, 304, 304L, 316, 316L, 409, 410, 430, and duplex stainless steel, conforming to ASTM A249, ASTM A269, ASTM A270, ASTM A312, ASTM A554, ASTM A778, EN 10217, EN 10296, EN 10312, DIN 17455, and DIN 11850.

What surface finishes are available for welded stainless steel pipe?

Available finishes: 2B (mill), No. 4 (brushed/satin), No. 8 (mirror), BA (bright annealed), and Ra ≤ 0.8 µm polished for sanitary service. Internal polishing to Ra ≤ 0.4 µm is available for pharmaceutical-grade tube.

What are typical applications for welded stainless steel pipe?

Welded stainless steel pipe is ideal for food processing, dairy, pharmaceutical, water treatment, HVAC, decorative and architectural piping, and low-to-medium-pressure industrial systems where cost efficiency is important.

Can I order custom lengths and wall thicknesses for welded pipe?

Yes. Custom lengths up to 12 m, non-standard wall thicknesses, and end treatments (beveled, plain, threaded, flanged) are available. Flexible trial orders starting from 100–300 kg are supported for standard and custom specifications; contact TeCarve sales for a quote.
