Rubber Expansion Joints
RUBBER EXPANSION JOINTS
Seiris’ rubber expansion joints are customized according to following constraints:
Temperature up to 200°C
Pressure up to 20 Bars
Diameter dimensions from 25 to 3000
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 agressiv when we go under dew point) : in order to adapt our products to those various conditions, we use 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.
