Description
Seiris’ metallic expansion joints are customized according to the following constraints: Temperature up to 1200°C
Pressure up to 70 Bars
Diameter’s dimensions from 15 to 7000 mm
We manufacture various types of :
- Circular expansion joints: axial, lateral, with hinge, Pressure balanced .
- Rectangular expansion joints: V and U shape
- Single convolution
Pumped fluid: all kind of (acid or strong bases very agressive when we go under dew point) : in order to adapt our products to those various conditions, we use the following steels:
304 -304L - 316 - 316L -321-309-310-253 MA- 904L-317L, and also all types of INCONEL and HASTELLOY
Our metallic expansion joints are studied, manufactured and tested further to internationals standards: EJMA, ASME and AD Merkblatter.
