The terms "seamless" and "welded" refer to the tube from which bends and tees are manufactured. |
||
Tubes shall be made by either the cold finished seamless, or welded and bead rolled process.
NOTE Electric resistance welding is not considered suit able for stainless steel tube for the food industry and electric resistance welded tubes are excluded from this standard.
All tubes shall be fully annealed and free from scale .
Welded tubes shall be manufactured from flat rolled strip, longitudinally welded across the abutting edges by a continuous automatic welding process, with or without the addition of filler metal. If filler wire is used, it shall comply with BS 2901-2.
For welded tubes, welds joining length of strip shall be cut out of the finished tube.
