Abstract
A pipe rupture restraint and shield diffuser assembly is installed on a pipe at a location where the pipe is subject or postulated to rupture and includes a cylindrical casing surrounding the pipe and having holes therethrough and a plurality of diffuser rings disposed in longitudinally spaced relation in an annular space between the casing and the pipe to form flow obstructions along the annular space whereby upon rupture of the pipe jet flow is diffused by flow past the diffuser rings and through the holes in the casing. The assembly can be attached directly around the pipe or can be independently supported.
Claims16
A pipe rupture restraint and jet shield diffuser assembly for installation on a pipe at a location where the pipe is subject to rupture comprising
- a cylindrical casing surrounding the pipe to define an annular space therebetween, said casing having holes therethrough extending substantially transverse to the longitudinal axis of said casing;
- and
- a plurality of diffuser rings disposed in longitudinally spaced relation in said annular space to form flow obstructions along said annular space whereby upon rupture of the pipe jet flow is diffused by flow past said diffuser rings and through said holes in said casing.
