ABSTRACT:
An insulator suitable for use with a truncated triangular shaped support member or skid pipe having a base member, a pair of converging side members which terminate in an apex member and a pair of shoulders extending oppositely one another from the joinder of the apex member and each corresponding side member. The insulator includes a base unit and a pair of converging side walls. When slidingly received around the skid pipe, the insulator closely conforms to the periphery of the base member and side members of the skid pipe. The side walls of the insulator preferably abut a lower lip of each shoulder so that molten slag and other impurities cannot migrate between the insulator and the skid pipe to degrade and dislodge the insulator.
The insulator is secured to the support member by its novel geometry; that is, when the insulator is slidingly received around the structural member, the converging side walls of the insulator bear against the converging side members of the structural member thereby maintaining the insulator in proper position on the structural member.
