Series SJ-221

The SJ-221 expansion joint features a unique arch design which provides greater movement capabilities without increasing face to face requirements. The single arch SJ-221 provides the same movement capabilities of a traditional double arch design and the double arch SJ-221 is equivalent of a quadruple arch product.

The SJ-221 expansion joint features a unique arch design which provides greater movement capabilities without increasing face to face requirements. The single arch SJ-221 provides the same movement capabilities of a traditional double arch design and the double arch SJ-221 is equivalent of a quadruple arch product. The same design which provides increased movements also increases the flexibility of the joint, resulting in lower spring rates. This means less stress on adjacent piping system components.

Flange drilling also available in all international standards or custom applications. For more information, contact EVR.

Control unit assemblies are recommended for all applications. To ensure correct length, customer should provide width of mating flange or flange specification.
