Abstract: A joint restraint is provided for a curved pipe joint having a curved pipe section joining two adjacent pipe sections. The pipes are joined using tubular sleeves held by hose clamps to form fluid tight seals, with two clamps on each end of the curved pipe sections and two clamps on each proximal end of the adjacent pipe sections. An inner strap extends between and fastens to one of the clamps on each adjacent pipe section forming a chord of an arc. An outer strap extends along an outer periphery of the joined pipes and fastens to the other clamps on each adjacent pipe section.

Abstract: A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position.

Abstract: A method and apparatus are provided for suspending an appliance from a plurality of support members which depend from overhead beams and structures of a building. A lower frame has a base with side walls extending from the base and joined to form a fluid tight container. The base has sufficient strength to support the appliance thereon when the lower frame is suspended from the support members and all the weight of the appliance is carried by the base. At least three connectors are provided, each fastened to at least one of the side walls and base. Each connector removably fastens to a different one of the support members. An upper frame can be fastened to the depending support members to further stabilize the frame. Straps can encircle the appliance to stabilize the appliance on the frame.
