Joint assembly for insulating high temperature fluid carrying conduits

摘要

A joint assembly connected with one end of a heat insulated conduit which includes an outer casing, a concentric inner core and an intermediate concentric layer of insulation material is disclosed herein. This assembly defines a passage extending from the conduit core outwardly to the outer surface of the joint assembly. This passage is provided such that fluid therein and under a predetermined amount of pressure in the direction towards the outer surface of the assembly will move out of the passage in the direction of pressure, i.e., to the outer surface of the joint assembly rather than into the layer of insulation material comprising part of the conduit.
