DN 15 to DN 6000. From DN 250 intermediate sizes can be manufactured without considerable additional costs. Rectangular expansion joints with rounded corners in any size are manufactured.
The standard expansion joints can be supplied for pressures up to PN 40 depending on nominal diameter, bellows construction and type of construction. Please request a quote for higher pressures.
or temperatures up to 600ºC, the standard material for bellows and conduits is V2A or V4A (material 1.4541 (321), 1.4301 (304), 1.4571 (316Ti), 1.4435, for higher temperatures it is material 1.4828 (308) or 1.4878). Special materials such as Hastelloy, Incoloy or Inconel can also be supplied. For multi-walled bellows it is possible, if required, to select a higher quality material for the internal and external layer than for the intermediate layers which are usually made of material 1.4301 (304). Connectors and anchorings are made of unalloyed steel, rust-proof or acid-proof stainless steel or high-temperature steel, depending on requirements.
Welding flanges, loose and integral flanges, threaded joints, in accordance with German and international standards. Special connections in accordance with customer drawings are also possible.
