The Versa Steel Split Commerical Ring is designed to compenstae for nominal variations in pipe wall thickness. When inserted into the pipe, the ring can be closed at the split or have a gap, depending on the inside diameter of the pipe. These rings are also designed and manufactured with an opening at the split which permits the welder to compress the ring when it is inserted into the pipe. When released inside the pipe opening, the ring will spring back and make contact throughout the insde circumference of the pipe. The usual procedure followed when using Versa Steel Split Commerical Rings is to insert the ring into one end of the pipe, and then bring the other pipe over the opposite end of the ring, forcing both ends of both pipes against whatever root opening spacers are furnished on that particular ring.
