Expansion Joints
MASTER BELLOWS
Metal joints with single or multiwall bellows in strips or sheet metal. The walls are longitudinally butt-welded in automatic TIG with arc welding control.
The connection weldings between the bellows and the flange/weld ends and the weldings of the external structures are done with automatic TIG, MIG, MAG processes with controlled parameters to guarantee the uniformity and the reproducibility of the product.
The welding procedures are in conformity with EN 15614-1, the welders are in conformity with EN287-1, and the operators are in conformity with EN1418.
