ABSTRACT:
A spherical fitting for intercoupling multiple sections of pipe has integral, radially extending, pipe-receiving outlets formed on the spherical body of the fitting. Each outlet is provided with an annular bevel on its outermost end for mating with a respective pipe section in a manner to present a joint configured to permit utilization of a full penetration circumferential weld. In an alternate application, the spherical fitting may be employed as a connector to join structural members in a tubular trusswork such as an offshore oil drilling platform.
