4 Design Data, Gaskets Grinnell Gasket Grade Index and Recoendations he Gasket Recoendation ables have been developed to assure maximum service life. he tables have been developed from information supplied by the material manufacturers of the elastomer, technical reference literature and testing conducted by Grinnell. In evaluating the gasket grade for intended service applications consideration must be given to the following: system operating temperature, fluid or solution concentration, and duration of service. All gasket recoendations are based on a temperature of C (0 F) unless otherwise noted. yco Building Services Products should be consulted if combinations of service solutions are being considered. Contact yco Building Services Products for recoendations for services not listed. Gasket recoendations apply to Grinnell gaskets only. hese listings do not apply for Grinnell Butterfly Valves.

A petroleumfree silicone based lubricant is recoended for all dry pipe systems. For low temperature services or dry systems in cold storage or freezer applications, use riseal freezer gaskets. For vacuum services greater than " Hg, riseal gaskets should be used. Note: Rigid couplings are preferred for vacuum, dry pipe and freezer applications.

10 Design Data, General Rigid Joints Flexible Joints Grinnell Rigid Couplings provide rigid gripping of the pipe. hey are designed to bring the pipe ends closely together and the coupling clamps firmly onto the pipe OD and also onto the bottom of the grooves. Because Rigid Couplings clamp around the entire pipe surface, they provide resistance to flexural and torsional loads and therefore permit longer spacing to ASM/ANSI B1.1 (Power Piping) and ASM/ANSI B.1 (Building Services) requirments as well as NFPA 1 (Sprinkler Systems). Grinnell Flexible Couplings act as an expansion joint, allowing linear and angular movement of the pipe. hey are designed with the coupling keys engaging the pipe without gripping on the bottom of the grooves, while still providing for a restrained mechanical joint. his is particularly useful to allow for pipe expansion / contraction and piping misalignment. Linear Movement (Flexible Joints) For thermal expansion the pipe ends at each joint should be fully gapped to the maximum end gap. his can be accomplished by pressurizing the system and then anchoring the system. Pipe nds Gapped for xpansion For thermal contraction with flexible couplings, the pipe ends at each joint should be fully butted. he system can then be anchored in place to prevent the pipe ends from opening up to the maximum end gap when pressurized. For design purposes, the maximum pipe end gap should be reduced to account for field practices as follows: herefore the following values should be used as available pipe end movements for Grinnell Figure 0, 0R, 0, and 0 Flexible Couplings: 1 1/ / Pipe nds Butted for Contraction nd Cap Reduction Maximum Pipe nd Cap Reduction Pipe nd Movements Cut Grooved % % Roll Grooved* YCNMCH/0 yco reserves the right to change the contents without notice * Roll grooved joints provide 1/ the available movement of cut grooved joints. yco Building Services Products.01

11 Design Data, General Angular Deflection Grinnell Flexible Couplings are capable of accoodating angular deflection. he deflection published in our literature is a maximum value. For design purposes the maximum deflection should be reduced to account for field practices as shown: 1 1/ Deflection Maximum Pipe Deflection Reduction 0% % xpansion / Contraction Grinnell Flexible Couplings are capable of accoodating pipe thermal movements provided they are properly gapped and a sufficient quantity of flexible couplings are used. Note that flexible couplings will not accoodate both full maximum linear movement and the maximum available angular deflection concurrently at the same joint. If it is desired to have both deflection and linear movement available, then the system should have sufficient flexible joints to accoodate the requirement.

12 Design Data, General hermal Movement he following guidelines are similar to any expansion joint: Its is recoended that anchors be installed at changes of direction on the pipe lines to control the pipe movement. he thermal expansion/contraction in the piping system can be accoodated utilizing Grinnell Flexible Couplings. In designing anchoring systems. It is suggested that the following be taken into consideration as a minimum: thrusts Frictional resistance of any guides or supports Centrifugal thrust due to velocity at changes of direction Activation force required to compress or expand a flexible coupling 1 1/. 1 1/ / / Activation Force Activation Force Lbs. N hree methods are available as examples to accoodate thermal expansion/contraction: 1) Design the system with rigid couplings and place expansion joints at the relevant locations. xpansion joints may be a series of flexible grooved couplings of a sufficient quantity to accoodate the movement. xpansion Joint ) Design the system with flexible and/or rigid couplings and allow the pipe to move in directions desired, with the use of anchors and guides if so required. With this method, it is important to ensure that movement at branch connections, changes of direction, equipment hookup, etc., will not cause damage or excessive stresses.

13 Couplings, Fittings & Flanges, Continuity Clip When a continuity clip is used electrical continuity across a Grinnell flexible coupling (Fig. 0 or 0) is maintained in a variety of situations including high current loads and extremely corrosive environments. In other words, the use of one clip per coupling offers the contractor a fast and simple means of providing earth continuity of steel pipework. Rigid type couplings have a build in feature which insure electrical continuity. herefore when using rigid couplings, there is no need for continuity clips. he Grinnell continuity clip is a light weight, stainless steel 01 clip, whereby tiny burrs provide proper grounding. It is designed for earthing requirements according British Standard (BS) 08. he Grinnell continuity clip complies to the I.. regulations, th edition, which requires equipotential bonding of conductive parts. hree clips cover the coupling range from 1" up to 1" and fit both the Fig. 0 and Fig. 0 coupling. yco BSP Article Number CLIP0 CLIP00 CLIP081 DAIL A Suitable for Size Coupling DAIL A Approx Weight General notes: Additional information is included in our data sheets and is available upon request. It is the Designer s responsibility to select products suitable for the intended service and to ensure that pressure ratings and performance data is not exceeded. Always read and understand the installation constructions. Never remove any piping components nor correct or modify any piping deficiencies without first depressurizing and draining the system.

15 Design Data, General Misalignment and Deflection Grinnell flexible couplings provide for restrained joints and allow for deflection to aid where the pipe or equipments is misaligned. Note that flexible couplings will not accoodate both full maximum linear movement and the maximum available angular deflection concurrently at the same joint. If it is desired to have both deflection and linear movement available, then the system should have sufficient flexible joints to accoodate the requirement. Flexible couplings are also useful in designing curved piping systems.

16 Design Data, General Pipe Support All piping systems require that the support system accoodate the weight of the pipe, joint connections, fluid and other system components. In addition, consideration may be necessary in reducing stresses, accoodation thermal expansion or contraction, building settlement, seismic movement, etc. he following table provides guidelines for grooved steel piping products without concentrated loads between supports. Note: he requirements of NFPA, ANSI, ASM or other code groups may require additional supports.
