ABSTRACT:
An improved insulated tubing string with insulated coupling formed of concentric tubing members insulated from each other to prevent heat from the inner tubing from being conducted to and through the outer tubing. The coupling joins the outer tubing of successive tubing assemblies to provide additional strength to the string and the inner tubing is insulated within the coupling to prevent heat loss at the coupling. The inner tubing is elongated during fabrication and joined to the outer tubing when elongated to reduce heat stress on the string when in use.
