BOLTLESS DESIGN The FJ-Restraint requires no threaded fasteners for assembly. The advanced design eliminates the need for flanged assembly connections in the casing(s). The resulting one-piece casing construction is an essential element that achieves restraint capabilities of 8.4d* tons of force for all sizes. By eliminating unnecessary components, the compact design allows a lightweight assembly for ease of installation.
OFFSET Each FJ-Restraint ball end provides a bending angle of up to ±15° to ±20° (depending on size). This corresponds to a total bending angle of ±30° to-±40°. By varying the length of the sleeve, the FJ-Restraint will also accommodate lateral offset of 4 to 20 inches. When special conditions demand, a FJ-Restraint of 3 to 12 inches in size can accommodate an additional bending angle. Please contact Romac Industries, Inc. for assistance when your application requires special consideration.
EXPANSION Since all of the FJ-Restraint's expansion occurs inside the ball joint, there is no need for expansion type sleeves. The centrifically cast ductile iron sleeve is one piece, which minimizes any turbidity.
TORSION The design of the FJ-Restraint allows rotation or torsion of the pipeline components. This freedom of movement prevents damage to flanges, valves and other structures associated with the pipeline.
EASY-TO-INSTALL Romac FJ-Restraint's arrive from the factory with tie-rods in place to prevent deflection and changes to the end-to-end dimension during transportation and installation. Tie-rods are then removed once installation is complete.
