JRE - Redflex M-150 Molded Expansion Joints, Single Arch are an economical way to alleviate pipeline stress. A unique design features a flexible rubber arch section with two independent steel flanges drilled to ASME 125 dimensions. Steel flanges rotate freely, allowing the joint to be installed where pipe flanges have rotated out of alignment. Flexibility of the rubber allows the joint to compensate for movement in any direction, as well as absorb vibration.
The arch section is constructed of layers of elastomer reinforced with nylon tire cord. Arches of the M-150 are shallow and spherically shaped to prevent possibility of build-up, making these joints excellent for slurry service. The smooth passage provides a non-turbulent flow path through the joint.
Steel flanges are drilled to ASME 125 dimensions, eliminating the need for back-up rings. Flanges are coated with three layers of chromate for a smooth, non-corrosive finish and are available threaded or with through-holes.
