A covering for insulating a pipe including a U-shaped refractory cast having embedded in the refractory cast a U-bolt, and a plurality of parallel rods welded to the bolt to form a cradle-like frame. The ends of the U-bolt project from the sides of the cast. The cast is seated against the pipe and supported thereto by assembling a collar member on each of the U-bolt ends. The sides of the collar members extend over and are seated against the pipe. Nut members are threaded to the bolt ends and tightened against the collar members. Refractory material in plastic form is applied to the pipe, covering the exposed portion of the pipe, the U-bolt ends, collars and nuts assembled thereto to completely insulate the pipe.
