Arch Type:

A full face integral flange design is available in both Single Arch and Multiple Arch Types expansion joints. These basic types can be manufactured to meet requirements of ASTM F1123-87. These types of expansion joints are available in several construction design series, based on the application pressure requirements.

Single Narrow Arch Type.

Construction is of fabric and rubber, reinforced with metal rings or wire. The full face flanges are integral with the body of the expansion joint and drilled to conform to the bolt pattern of the companion metal/FRP flanges of the pipeline. This type of rubber expansion joint face flange is of sufficient thickness to form a tight seal against the metal/FRP flanges without the use of gaskets. The shortest rubber expansion joint face to face dimensions are available with this type of rubber expansion joint construction.
