The Romac FlexiJoint is a flexible, ductile iron joint developed to accommodate pipeline forces that could result in damage, or loss of service. The FlexiJoint compensates for expansion, contraction, rotation, bending and settlement of your pipeline all at the same time. Available with either flanged or mechanical joint ends. When properly installed, the FlexiJoint can be used at working pressures up to 350 psi. Download a brief video (MPEG4, 2.5MB) showing the FlexiJoint's movement. DRAWINGS: SIZE SPECIFIC DRAWINGS |

No Bolts The casing of the FlexiJoint is one piece and requires no threaded fasteners for assembly. This unique design feature eliminates flanged assembly connections. The resulting monolithic casing construction is an essential element that achieves restraint capabilities of 8.4d* tons force for all sizes. By eliminating unnecessary components, the compact design allows a lightweight assembly for ease of installation. |

| Accommodates Bending and Offset of Pipelines A single FlexiJoint ball end is able to provide 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 FlexiJoint will also accommodate lateral offset of 4 to 20 inches. When special conditions demand, a FlexiJoint 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. Reacts to Torsion The design of the FlexiJoint will allow rotation or torsion of the pipeline components. This freedom of movement prevents damage to flanges, valves and other structures associated with the pipeline. The FlexiJoint allows this movement while still accommodating bending and offset of the pipeline. Superior Corrosion Resistance FlexiJoint components, including the stainless steel lock ring, are lined and coated with fusion bonded epoxy powder. Each component of the FlexiJoint is holiday tested. This coating provides superior corrosion resistance. Excellent Watertightness The seals of the FlexiJoint are specially molded rubber gaskets. These gaskets are used in the casing to allow deflection and in the ball to allow expansion and contraction. A casing cover is provided to assure contamination free operation. 1 Where “d” is in inches. |
