Different types of rubber expansion joints
Description
Seiris’ rubber expansion joints are customized according to the following constraints:
- Temperature up to 200°C
- Pressure up to 20 Bars
- Diameter dimensions from 25 to 4000 mm
We manufacture all types of:
- Circular expansion joints
- Single convolution, double or triple convolutions, with tie rods, conical, balanced pressure
- And rectangular expansion joints: Single convolution or double convolutions
Pumped fluid: all kind of (acid or strong bases very agressive when going under dew point) : in order to adapt our products to those various conditions, we use the following rubbers :
Rubber, Neoprene, EPDM, Silicon, Butyl, Chlorobutyl, NITRILE, SBR, HYPALON AND VITON
For flanges we use following steels: S 275JR, S355J2G3, AISI 304, 316, 316L.
Rubber expansion joints are studied, manufactured and tested following international standards : FSA and ASTM.
