Stainless Steel Welded Tube
Welded stainless steel tube to EN 10296-2, ASTM A269 and GOST 11068-81 in the standard austenitic grades. This is the welded counterpart to our seamless stainless tube to GOST 9941; it is the economical choice for heat exchangers, instrumentation lines, food and pharmaceutical tubing and decorative work where the longitudinal weld is acceptable.
Price: quoted per specification. Stainless surcharges move with nickel and molybdenum, so each quotation is confirmed at the time of order.

Steel grades
| Grade | AISI | Characteristic | Typical use |
|---|---|---|---|
| 08Х18Н10Т | 321 | titanium stabilised, no sensitisation after welding | instrumentation lines, welded assemblies |
| 12Х18Н10Т | 321 | titanium stabilised, higher temperature service | process tubing, heat exchangers |
| 10Х17Н13М2Т | 316Ti | molybdenum + titanium, better pitting resistance | chemical, seawater, pharmaceutical |
| AISI 304L | 304L | low carbon, weldable | food and pharma, general corrosion service |
| AISI 316L | 316L | low carbon, weldable without stabiliser | chloride and marine environments |

Coil delivery
For small outside diameters with a thin wall, the same welded stainless tube can be supplied as a continuous coil — see welded precision tube coil. Typical coil: outer diameter approx 1000 mm, inner hole approx 600 mm, weight approx 200 kg per coil, adjustable to your decoiler.
Applications
- Heat exchangers and condenser tube
- Instrumentation and impulse lines
- Food, beverage and pharmaceutical lines
- Decorative and furniture tube
- Automotive fluid and exhaust lines
Quality and packing
Each lot is tested for chemical composition, mechanical properties, dimensions and surface, with flattening and flare tests on request. Coils are strapped and wrapped; straight lengths are bundled with end protection, in wooden cases where agreed.
