Contact Victaulic for specific details. Each restraint ring shipment includes restraint ringplacement and welding data that is specific to application or project requirements.(3) Restraint rings must be welded perpendicular to the pipe axis with a tolerance of L± 1/16"/1.6 mm.(4) Flare bevel groove weld size in table is the minimum requirement. Depth of preparation S = (d) ÷ 2;Weld size E ≈ S * 0.625 per AWS D1.1. For a double flare bevel groove weld, the weld on the back side of therestraint ring must not extend beyond the outermost edge of the ring. The coupling shoulder must have unrestrictedcontact with the ring and the pipe O.D.3/323/323/323/323/323/323/323/323/323/321/83/323/321/83/323/321/83/323/321/81/8Note: The data in this table only applies when carbon steel couplings are being used on carbon steel pipe.www.victaulic.comVICTAULIC IS A REGISTERED TRADEMARK OF VICTAULIC COMPANY. © 2013 VICTAULIC COMPANY.
