Abstract: A spigot for a line-stopping sheath assembly includes a flange including a flange plate and a flange barrel. The flange barrel includes a wall extending from the flange plate, with an end of the wall of the flange barrel opposing the flange plate having a projection defining a periphery of a socket area for receiving an end of a pipe. The spigot also includes a pipe having an end disposed within the periphery of the socket area defined by the projection of the flange barrel.

Abstract: An improved tapping sleeve includes a first sleeve member having an outlet aperture, a second sleeve member, and a unitary gasket. An outlet retaining ring is positioned around the outlet aperture. A pair of end retaining lips are positioned on inner surfaces of the first and second sleeve members at opposing ends of the sleeve members. The gasket includes a gasket outlet having a pair of tapered surfaces on opposing longitudinal sides of the gasket outlet. The gasket, when positioned on a pipe in an un-stretched, uncompressed position subtends an arc of less than 360 degrees, creating a gap in the gasket. As the first and second sleeve members are connected, the outlet retaining lip engages armor members on the gasket, thereby circumferentially stretching the gasket and closing the gap. The tapered surfaces and the outlet retaining lip prevent excessive gasket flow into the outlet aperture.

Abstract: A high-strength low-bolt pipe clamp of the type having rigid lugs fixed to the ends of a flexible band results from an improved method for connecting the lugs to the band. The lugs are of cast material, while the band is of stainless steel. The connection between each lug and the band end is via a pair of initially open jaws on the lug that define a slot in which the band end is inserted. A plurality of spaced holes through the upper jaw of the lug are in registry with holes through the band end when it is inserted in the slot. The jaws are clamped together and deformed toward the band, and a weld is made in each hole to bind the two jaws together permanently and to securely affix the band to the jaws at the weld points. Preferably the weld fills each hole approximately flush with the surface of the lug.
