Abstract:
A refractory insulator for insulating the joint between a long skid pipe, a supporting crossover pipe at right angles, and a riser for supporting both. The insulator comprises two halves each having a top portion and two pivoted lower side portions. When the halves are abutted, and the pivoted lower side portions are wrapped around the crossover pipe, the insulator will effectively seal the joint between these two pipes at the point of support by the riser. The pivoted portions are formed by reticulated wires embedded along the inner surface of the insulator and which provide pivotal joints between the upper portion and two lower side portions. The gaps at the pivoted joints can then be filled with insulating grout material.
