Tubiflex compensators offer high reliability, no ageing, no permeability, resistance to corrosion, high operating temperature. Metal joints with single- or multi-wall gussets machined from strip or sheet metal. Walls are longitudinally welded head-to-head in automatic TIG with arc control. Connection welds between gussets and flanges/sleeves and external structure welds are performed by automatic TIG, MIG, MAG processes with controlled parameters to ensure product repeatability. The waves are formed automatically controlled by PLC. The forming process, free of creep and lamination, guarantees perfect consistency of the wave profile with minimum stretching of the material. The compensator can be used for superheated water, steam, diathermic oil and steam turbine lines.
