Features

With bigger pipe dimensions, welding can sometimes be more economical than hard soldering since heat is applied specifically to the area of the weld seam for a reliable connection. With hard soldering, the whole fitting has to be heated instead. This can be a lengthy and time-consuming process as heat is rapidly dissipated and consequently more gas will be consumed. Additionally, capillary solder fittings are not available for dimensions exceeding 108 mm outside diameter.

SANHA offers the following range of fittings for welding made of copper:

  • Copper weld elbows according to [DIN 2607 - insert UK norm here], catalogue number 3k, dimensions: 35 x 1.5 mm up to 267 x 3 mm
  • Torispherical heads for pre-welding according according to [DIN 28011 - insert UK norm], catalogue number KB, dimensions: 35 x 1.5 mm up to 267 x 3 mm
  • Angle flanged wheels for pre-welding in accordance with [DIN 86341 - insert UK norm here], catalogue number WBS V, dimensions: 15 x 1.5 mm up to 267 x 3 mm
