    ANSI Flanged Single Sphere Rubber Expansion Joint

    1. ANSI Flanged Single Sphere Rubber Expansion Joint 150LB

    The "ANSI Flange" refers to two end flanges of the rubber expansion joints that are in compliance with ASME / ANSI B16.5. Since a rubber expansion joint is the weakest point of the pipeline, usually only low pressure rating 150LB flanges are applied as end connectors. "Single Sphere" refers to the shape of the rubber bellow which is also called "body" of a rubber expansion joint. There is also "Double Sphere Style" body available.
