As in other styles of expansion joints, beveled weld end designs can be increased in length with minimal cost impact.  DME will design the appropriate expansion joint for your application.

For installation convenience, victaulic grooved ends can be provided on all externally pressurized expansion joints.  Special alloys can always be furnished on request.

Carbon steel plate flanges are used in most externally pressurized joint designs.  The internal pipes act as flow liners to keep a smooth flow.

Forged flanges are provided for higher pressure applications or when required by specifications.  DME can custom build all stainless steel joints for corrosive applications.

Dual expansion joints compress from both directions.  This style expansion joint can be designed for 16" of movement or more.  The joint must be placed in the middle of the piping run to function properly.
