Abstract: Certain embodiments of the present invention relate to methods for the production of arcuate polymeric saddles typically used to anchor and suspend insulated or non-insulated pipes. Ribs may be included to provide strength. Rounded corners on the saddles facilitate comfortably introducing and placing the saddles into hangers as well as improving use.

Abstract: A thermal insulation structure of fibrous material is described. The insulation comprises alternating and abutting parallel strips of fibrous material wherein the fiber orientations in alternate strips are at right angles to each other. This structure preserves the insulating properties of the fibrous material while permitting it to be readily curved around a pipe without creating stresses in the material which would cause it to tend to straighten out. The fibrous material may be glass fiber, mineral wool or the like, preferably glass fiber. The density of the individual insulating batt strips may be as low as 0.5 pcf, but is preferably at least 1.5 pcf. Both pipes and curved vessels may be advantageously insulated by this invention.
