Abstract: A thermally insulated tubular made up of a first pipe having a first pipe diameter and a second pipe having a second pipe diameter. The second pipe diameter is greater than the first pipe diameter. The first pipe positioned along a conduit of the second pipe and spaced-apart from an interior surface of the first pipe. A thermally insulating composition coupling the first pipe to the second pipe and positioned in an annulus formed by the first and second pipe. The thermally insulating composition containing a thermally insulating or thermal shock resistant layer and a thermally insulating concrete composition.
