DIN 11851 unions with butt-welded collar
DIN 11851 welding parts form the connection between unit-components, pipe-systems, valves or hoses. If good manufacturing practise is performed, the male-part should be welded on the pipe-end because the nut protects the liner from abrasion.
Pictured welding parts are also available as custom-made reductions, extensions or bends.
