Installation Instructions JCM Bolted Steel Couplings Models 201, 202, 203, 204
Read instructions before starting installation* Review of “Tricks of the Trade” on the reverse will assist with installation. For purposes other than water, contact JCM Industries for application and product assistance. NOTE: Maximum 90 PSI working pressure on gas service applications. For higher pressure ratings, contact JCM Industries Engineered and Technical Sales. 1. Clean and scrape pipe. Remove any scale, pipe wrap, debris or dirt that may interfere with the complete sealing of the gasket. Inspect pipe for integrity, size, outside diameter and surface irregularities. Con fi rm the proper size and range of coupling. Inspect fi tting to ensure all parts are included. Fittings furnished with stainless steel hardware; see reverse for fastener management. 2. Lubricate the pipe and the fi tting gasket with soapy water. Do not use oil base pipe lubricant. 3. Measure back on each pipe end one-half of the middle ring length plus two inches and place a reference mark. These marks will be a visual reference point for centering the middle ring over the joint. 4. Install follower rings, then gasket onto the pipe ends. NOTE: Flat side of the gasket face meets the follower ring, the tapered side inserts into the middle ring. 5. Install middle ring on one pipe end. Insert other pipe end into middle ring and center the middle ring over the joint, between the reference marks. Lift the middle ring to insure that the gaskets are evenly centered in the ends. Center
follower rings on the pipe to ensure even gasket compression into the middle ring. 6. Torque coupling bolts on opposite sides, using a star rotation pattern, drawing up the followers evenly until all bolts have been tightened to a minimum of 75 foot pounds of torque. NOTES: On joints that do not permit centering of the coupling, the pipe ends must be inserted past the end of the gasket a minimum of one and one-half (1-1/2”) inch. For applications with de fl ection or o ff set pipe ends, the pipe end must be inserted a minimum of one and one-half (1-1/2”) inch past the end of the gasket after the de fl ection/ o ff set has occurred. Do not exceed a recommended 4° of pipe de fl ection with the coupling without inspecting the centering and sealing of the gasket in the middle ring and follower ring. Excessive de fl ection will cause the gasket to improperly seal. IMPORTANT: Standard couplings do not provide for axial pipe movement. In applications in which lateral pipe pullout may occur, pipe restraint must be provided. See fi tting manufacturer recommendations for applications on High Density Polyethylene Pipe. Gaskets: for replacement or loose gaskets, cut-to- fi t by maintaining the the bias (angle) cut.
INT2010304-0823 *Ensure fi tting is suitable for application (con fi rm size, materials, pressure ratings, line content, meets local governing & association standards, etc.). Pipeline operation forces, including pressure fl uctuations, thermal expansion/contraction, movement/shifting, etc. will in fl uence the success of the application. Proper anchorage, restraint, harnessing, thrust blocks or other devices must be provided to prevent pipe movement (lateral, angular, axial) or pipe pullout from the bolt-on fi tting. Inspection of the pipe integrity is the responsibility of the end user. JCM recommends the use of calibrated torque wrench. Failure to follow installation instructions will result in voided product warranty. For application review or questions contact JCM Industries at 1-800-527-8482, 903-832-2581
