FID Fowler Company Submittal -Bid Item#27 ROMAC INDUSTRIES, INC. RESTRAINED FLANGED COUPLING ADAPTER FOR STEEL AND DUCTILE IRON PIPE 3 THROUGH 12 INCH 40. SUBMITTAL INFORMATION APPROVED USE The Restrained Flanged Coupling Adapter is used to connect plain end IPS sizes STD steel or ductile iron pipe to a flanged pipe or fitting. It provides flexibility before and after installation, and a RomaGrip wedge style restrainer provides restraint for the plain end pipe.Not for use on plain end mechanical joint fittings. The RomaGrip may be used on cast iron pipe as long as it has the same OD as ductile iron pipe. Note: Some initial axial movement may occur in lug style restraints as the lugs seat.Movement is directly related to the size of the piping system and the system pressure.In general terms movement of approximately 0.25 can be expected in restraints under 16".For larger sizes,movement of approximately 0.40 may be seen.If this is critical to your application please contact Romac Engineering for additional information.
