Laminated insulation rock wool elbow structure

Abstract

A laminated insulation rock wool elbow structure, comprises at least an insulating member configured to be bent to form a semi-cylindrical elbow structure for installation on an outer circumferential surface of a pipe elbow. Each insulating member, in an unbent state, defines a short axis and a long axis, wherein the short axis is generally perpendicular to the long axis; the insulating member includes, at opposite ends along the short axis, an inner curved section and an outer curved section disposed opposite to each other, wherein a length of the outer curved section is greater than that of the inner curved section; the insulating member further includes, at opposite ends along the long axis, two side curved sections disposed opposite to each other, each of the side curved sections having two ends respectively connected to the inner curved section and the outer curved section, and a distance between the two side curved sections gradually increases in a direction from the inner curved section toward the outer curved section.
