This motion can be either gradual or sudden, and places damaging shear and bending forces on pipelines. In areas close to, or within structures where differential movement can occur, pipelines should be restrained and supported to isolate and accommodate movement in a controllable manner at a designated location. FLEX-TEND flexible expansion joints provide pipeline protection from the stresses produced by these forces with their ability to deflect up to 20 degrees per ball, in any direction, while simultaneously expanding or contracting. They are available in sizes from 2 inches to 48 inches and can be used on ductile iron, steel, or PVC pipelines for:Connection to buildings, tanks, and other structuresUnderground to aerial transitions such as bridgesAreas of anticipated ground movement and unstable soilsAreas near roadways and damsActive faults crossings and liquefaction zones The FLEX-TENDS are available with both flange and mechanical joint end connections for adaptable protection for pipelines, pumps, bridge crossings, tank connections and many other critical installations, either above or below ground. Sizes of 3-inches through 24-inches are rated for 350 psi working water pressure. Sizes of 2 inch, 30 inch, and larger are rated for 250 psi working water pressure. FLEX-TENDS are manufactured entirely of ductile iron, conforming to all applicable requirements of ANSI/AWWA C153/A21.53 and FLEX-TENDS are totally protected from internal corrosion with a lining of fusion-bonded epoxy. FLEX-TEND flexible expansion joints are available in double ball or single ball configurations. Double-ball units offer the unique ability to accommodate a considerable degree of close-coupled vertical subsidence and will deflect up to 20 degrees per ball in any direction. Single-ball configuations can be used in pairs with a spool piece between them to increase the offset between the two ball ends. Expansion/contraction capability is cast as an integral part of the ball and socket, and can be adjusted with additional sleeves installed at the factory prior to shipping or in the field at a later date. The use of additional sleeves increases both the axial movement and the available offset.

Due to their design, expansion joints generate end thrust when subject to internal pressure, as seen in Figure 1.1. This end thrust must be accounted for in pipeline design. The end thrust generated by either the FLEX-TEND or EX-TEND is calculated by multiplying the internal pressure (PSI) by the area listed in Table 1.1.When used in a long and relatively straight pipeline, the pipe-to-soil friction is generally sufficient to balance the force. The use of thrust blocks or other means of anchoring is required when fittings are placed in close proximity to the expansion joint underground. This protects the pipeline from the tendency of the unit to expand when pressurized. In an above ground installation such as a bridge application, some means must be provided to prevent the expansion of the joint due to internal pressure. This can be accomplished by anchoring the piping to the structure while allowing room for movement when motion occurs. Please also consider EBAA’s thrust or Force Balanced FLEX-TEND models that do not generate axial thrust under water pressure.In order for the FLEX-TEND and EX-TEND to protect pipeline connections, any load must be transferred to the unit by the restrained joints. Depending on the piping arrangement and the anticipated movement of the pipelines, adjacent piping must be restrained to adequately transfer the loads to the unit. Joint restraint is provided with each mechanical joint end connection. The Table 1.2 lists some of the restraint products offered by EBAA Iron, Inc. as well as the pipe material on which each is used.Weld-on flanges are generally used for applications on steel piping.
