Twin pin series anchors are excellent for anchoring multiple layer refractory linings. The twin pin anchor type P is fastened by stud welding. The insulation is simply applied over the anchor and anchor ends projecting beyond the insulation are then bent open over the washers provided.
As Type STP, the anchor is used for simple anchoring functions, e.g. with relatively light materials or in flat positions. Type CTP with its corrugation provides a greater retaining capacity for the refractory material. Type HTP is notable for its deeper corrugations which produce a further improvement in retaining capacity.
