Abstract: An insulation hanger for supporting a compressible insulation blanket upon a supporting wall which is formed of three pieces, the first of which is an end weldable stud welded to the supporting surface and upon which the blanket to be secured is impaled. The end weldable stud includes a plurality of annular grooves of reduced cross section providing a shoulder at the juncture between the groove and the body of the stud. A flat washer like blanket retainer is utilized which has a keyhole aperture which permits the retainer to pass over the stud through a larger hole to compress the blanket and thereafter to be moved translationally to an aperture of size approximating the groove to interlock the blanket retainer with the shoulder of the stud.

Abstract: The present disclosure is for improvements to metallic refractory anchors heretofore in use which are of a general S type configuration and which are welded to metallic walls of vessels to secure in place refractory insulation of a high abrasion resistance. The improvements consist of reforming the weld end of the S anchor in a manner to reduce the length to width ratio of the weld end to approximately no greater than 6 to 1 to permit stud welding of the anchor by the stud end welding technique. Additional metallic members are resistance welded to the weld end of the anchor to decrease the length to width ratio to within the range capable of stud welding. The additional metallic members may be formed of separate members or by extended legs of the metal anchor folded back onto a weld projection and resistance welded in place.
