Insulated Welded Joint for Pipe-in-Pipe systems
An insulated joint in a pipe-in-pipe system comprises a weld that connects two inner pipes while respective outer pipes circumferentially enclose the inner pipes and terminate at a position distal from the weld. Respective rings are coupled to the inner pipes at the distal position and the outer pip...

Summary: | An insulated joint in a pipe-in-pipe system comprises a weld that connects two inner pipes while respective outer pipes circumferentially enclose the inner pipes and terminate at a position distal from the weld. Respective rings are coupled to the inner pipes at the distal position and the outer pipes are welded to the rings. A joint insulation material covers the weld, and a sleeve segment covers the weld and joint insulation material. Preferably, the sleeve segment is formed from two half-pipe sleeve portions and welded to the rings to so secure the sleeve segment to the joined pipe-in-pipe segments. Contemplated pipe-in-pipe systems have significantly reduced thermal loss and provide strength sufficient for a pipe laying process that includes pipe bending and pipe straightening. |
