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.

Spherical connector having integrally formed outlets

A pre-fabricated welded tubular coupling particularly adapted for use in the construction of offshore platforms comprises a tubular elbow tangentially secured to a straight pipe segment solely along the line of intersection therebetween. A cutout or opening in the backwall of the elbow is configured to complementally receive a portion of the periphery of the pipe to enhance the integrity of the interconnection between the latter and the elbow. The opening has a marginal edge which defines a continuous line of contact with the pipe for welding of the components to form a unitary coupling. In preferred forms, the elbow presents a 90.degree. arc and is arranged such that each leg forms approximately a 45.degree. angle with the pipe. In another embodiment, the elbow extends through 135.degree. and is attached to the pipe in a manner to form approximately 90.degree. and 45.degree. angles between the respective legs and the pipe.

Integral connector for tubular structures

A pipe cross fitting for interconnecting tubular structural members of an offshore platform of the type used by the oil industry. The cross fitting is reinforced by the addition of an internal structural element that extends across the central open portion of the fitting and into all of the branches of the fitting to resist the tension and compression forces applied to the fitting during use.

Reinforced pipe cross fitting

Structural connector for tubular members used in trusses and the like comprises a one-piece forged element comprising at least a portion of a tubular primary member with a longitudinal central axis and a pair of first and second tubular secondary members integrally connected to one side of the principal member. The secondary members have longitudinal central axes coplanar with the axis of said portion of said primary member and the axes of the secondary members intersect each other at a point displaced to the same side of the axis of the primary member where the secondary members intersect one another.

Structural connector

In a connector, as used to interconnect structural members in a trusswork, an elbow and a pipe, which may be another elbow, are provided with suitable slots receiving a plate, and the elbow, pipe, and plate are welded together.

Gusseted connectors

In a double-sigmoid connector, as used to interconnect structural members in a trusswork and comprises a pair of arcuate elbows joined to each other at their outer peripheral midsections, a pipe extends through an opening in the outer peripheral midsection of each elbow and is joined to each elbow so as to join the elbow to each other.
