TECHNICAL DATA COUPLING FLEXIBILITY (CONT.) EXAMPLE 4 Anchor at “A” to support weight of vertical water column. Use spring hanger at “D” and “E” to allow movement of vertical piping. Anchors at “B” and “C” if offsets at L1 and L2 are insufficiently long to handle expected pipe movements. L1 D A VERTICAL COLUMN LATERAL RESTRAINT B System with no pressure partially deflected HORIZONTAL RUN System pressurized fully deflected EXAMPLE 5 A grooved coupling joint installed in a partially deflected condition between anchor locations will deflect to its fully deflected condition when pressurized. Hangers and supports must be selected with consideration of the hanger’s capability to provide lateral restraint. Light duty hangers, while acceptable in many installations, may deflect against the application of lateral forces and result in “snaking” conditions of the pipe system. RISER DESIGN: Risers assembled with Gruvlok Flexible couplings are generally installed in either of two ways. In the most common method, the pipe ends are butted together within the coupling joint. Note that when installing risers, the gasket is first placed onto the lower pipe and rolled back away from the pipe end prior to positioning the upper pipe. Anchoring of the riser may be done prior to pressurization with the pipe ends butted or while pressurized, when, due to pressure thrust, the pipe ends will be fully separated. An alternative method or riser installation is to place a metal spacer of a predetermined thickness, between the pipe ends when an additional length of pipe is added to the riser stack. The upper pipe length is anchored, the spacer removed and the coupling is then installed. This method creates a predetermined gap at each pipe joint which can be utilized in pipe systems where thermal movement is anticipated and in systems with rigid (threaded, welded, flanged) branch connections where shear forces due to pressure thrust could damage the rigid connections. C E VERTICAL COLUMN L 2 The following examples illustrate methods of installing commonly encountered riser designs. RISERS WITHOUT BRANCH CONNECTIONS Install the riser with the pipe ends butted. Locate an anchor at the base of the L riser (A) to support the total weight M of the pipe, couplings and fluid. Provide pipe guides on every other pipe length, as a minimum, to prevent possible deflection of the pipe line at the coupling joints as the riser expands due to pressure thrust or thermal growth. Note that no intermediate anchors are required. When the system is pressurized the pipe stack will “grow” due to pressure thrust which causes maximum separation of pipe ends within the couplings. The maximum amount of stack growth can be predetermined A (see Linear Movement). In this example the pipe length “L” at the top of the riser must be long enough to permit sufficient deflection (see Angular Movement) to accommodate the total movement “M” from both pressure thrust and thermal gradients. RISERS WITH BRANCH CONNECTIONS Install the riser with the predetermined gap method. Anchor the pipe at or near the base with a pressure thrust anchor “A” capable of supporting the full pressure thrust, weight of pipe and the fluid column. Anchor at “B” with an anchor capable of withstanding full pressure thrust at the top of the riser plus weight of pipe column. Place intermediate anchors “C” as shown, between anchors “A” and “B”. Also place intermediate clamps at every other pipe length as a minimum. When this system is pressurized, the pipe movement due to pressure thrust will be strained and there will be no shear forces acting at the branch connections. B C C C A 220 GL-6.11 www.anvilintl.com
