ABSTRACT:
A jacketed pipe assembly of inner and outer tubular members having respective inner and outer corrugated metal tubes arranged in spaced relationship to define therebetween a fluid-circulating chamber adapted for the circulation therethrough of a temperature controlling fluid for aiding in the flow of a processing fluid through the inner tubular member. Coupling sleeves are connected by continuous welds to opposite ends of the inner corrugated tube, and means are connected to the outer ends of the outer corrugated tube and to the respective coupling sleeves to define therebetween respective opposite ends of the fluid-circulating chamber. The continuous connecting welds are surrounded by the fluid-circulating chamber, but are isolated therefrom by being enclosed within respective enclosures which are vented exteriorly of the pipe assembly so that cross-contamination between the inner corrugated tube and the surrounding fluid-circulating chamber will be prevented in the event of rupture of the continuous welds.
