Dismantling joints
made of epoxy coated steel

When valves or pumps are mounted or dismounted in piping systems, they rarely fit straight away. This is where dismantling joints come into play and provide the necessary length compensation. Depending on what is needed, the types BF2, BF3 and BF4 with the bore patterns PN 10 and PN 16 are in stock as standard. Special sizes or lengths can be custom-made on request.
