HD Fowler Company Submittal -Bid Item#27 <br /> ROMAC INDUSTRIES, INC. <br /> ROMAGRIP <br /> MECHANICAL JOINT RESTRAINING GLAND <br /> 3 THROUGH 12 INCH <br /> SUBMITTAL INFORMATION <br /> USE The Romac RomaGrip restraining gland is used for the <br /> restraint of mechanical joint ductile iron pipe, valves, fittings, and fire <br /> hydrants in water transmission and fire protection lines. It may also <br /> be used on IPS sizes steel pipe(minimum thickness STD weight <br /> class pipe)with MJ by IPS transition gasket.The RomaGrip replaces <br /> costly concrete thrust blocks, corrodible steel tie rods and clamps. <br /> Not for use on plain end mechanical joint fittings. The RomaGrip may <br /> be used on cast iron pipe as long as it has the same OD as ductile <br /> iron pipe. <br /> Note: Some initial axial movement may occur in lug style restraints as the lugs seat. Movement is directly <br /> related to the size of the piping system and the system pressure. In general terms movement of <br /> approximately 0.25 can be expected in restraints under 16". For larger sizes, movement of <br /> approximately 0.40 may be seen. If this is critical to your application please contact Romac <br /> Engineering for additional information. <br /> MATERIALS <br /> Gland Ductile (nodular) iron, meeting or exceeding ASTM A 536-84, Grade <br /> 65-45-12. <br /> Gaskets A standard MJ gasket is used with this fitting. <br /> Meets ANSI/AWWA C111/A21.11 for gasket specs. <br /> Restraining Bolt 7/8—9 roll thread, Ductile (nodular) iron, meeting or exceeding <br /> ASTM A 536-84. <br /> Restraining Lugs Ductile (nodular) iron, meeting or exceeding ASTM A 536-84. <br /> Heat treated using a proprietary process. <br /> Lug Locators Polyurethane, a thermo-set plastic. <br /> Coatings Shop coat applied to the casting for corrosion protection in transit. <br /> Epoxy coating optional. <br /> PERFORMANCE <br /> Nominal Number of Approx.
