ABSTRACT:
A coupling for sealingly joining together two sections of gas-containing pipe. The coupling comprises an annular housing having two end sections with an inside diameter substantially the same as the pipe outside diameter, and an intermediate section with an inside diameter greater than the pipe outside diameter and forming an annular space therebetween. The two end sections are capable of being welded to the pipe, and into the annular intermediate space is inserted an annular elongated C-shaped sleeve. Also included are pressurization means for compressing the sleeve against the pipe sections to seal the joint therebetween.
