摘要:
A split, ring-shaped pipe spacer used to maintain separation between a pipe and a fitting shoulder during welding. The spacer has pairs of yieldable offset segments. The two segments of each pair bulge from the spacer body in opposite directions to maintain proper spacing between the pipe and fitting during welding. The opposing offset segments also permit bidirectional insertion of the spacer into the fitting, position the spacer body out of contact with both the pipe and the fitting, and minute and distribute the stress imparted to the spacer when forming the segments during manufacturing. The spacer ends forming the split in the spacer have a tongue-in-groove shape to accommodate circumferential expansion of the spacer under compression of the pipe.
