Pipe joint restraint

摘要

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. The straps are in a plane through a center of the flow path of the joined pipes.

主权项

1. A pipe joint having a first flow path with a first centerline passing through a first adjacent pipe section, a pipe fitting having two opposing ends, and a second adjacent pipe section so the pipe fitting separates the adjacent pipe sections, each adjacent pipe section having an end abutting a different one of the ends of the the pipe fitting and being sealingly joined to the pipe fitting by a separate, removable tubular seal with liquid flowing through the adjacent pipe sections, the joint further comprising:
a first strap extending between the adjacent pipe sections, the first strap having opposing ends each fastened to one of a first and second pipe connector, each first and second pipe connector encircling and clamping to a different one of the first and second adjacent pipe sections, the first strap having a length extending in a first plane which plane also contains the first centerline, the first and second pipe connectors each being fastened to only one strap; and a third pipe connector directly connected to the first strap and located between the first and second pipe adjacent pipe sections and further located to encircle and clamp to the pipe fitting; and a second strap having a length extending in the first plane, the second strap having opposing ends each fastened to one of a fourth and fifth pipe connector, the second strap connected to one of the adjacent pipe sections diametrically opposite the first strap with the fourth pipe connector connected to one of the adjacent pipe sections and the fifth pipe connector connected to the other adjacent pipe section.
