Pipe heating structure and coupled pipe heating structure

Abstract

Aiming at providing a heat generation layer easily attachable or detachable to or from an outer circumferential face of a pipe, and at efficiently heating the inside of the pipe (particularly in the vicinity of a joint), disclosed herein as a solution is a pipe heating structure having a cylindrical main body; a ring-shaped joint that is attached to an end of the main body, and extends from an outer circumferential face of the main body in a direction perpendicular to an axis of the main body and away from the axis; and a sheet-like heater that is attached to the outer circumferential face of the main body, and has a first insulating layer, a heat generating layer, and a second insulating layer stacked therein in this order, the joint having no sheet-like heater on the outer circumferential face.

Dependencies are inferred from the claim text.
