Twin pin series anchors are excellent for anchoring multiple layer refractory linings. The twin pin anchor type H is designed for fastening by hand welding wherever small quantities have to be fastened or where no stud welding machine is available. 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 STH, the anchor is used for simple anchoring functions, e.g. with relatively light materials or in flat positions. Type CTH with its corrugation provides a greater retaining capacity for the refractory material. Type HTH is notable for its deeper corrugations which produce a further improvement in retaining capacity.
