Claims

[Scope of Claim for Utility Model Registration] 1. A cover made of a metal plate that is fitted onto the curved part of a pipe without contacting the pipe, and which is a narrow metal plate that is wide in the center and narrows towards both ends. A plurality of short cylinders formed into a cylindrical shape using a button punch method, which is bent along the outer circumference of the tube and connected by fitting a fitting protrusion formed at the other end into a bag-shaped fitting groove formed at one end. A cushioning material consists of an exterior material that is fitted externally in the direction of the tube axis, and an exterior material made by overlapping the ends of each short cylinder and joining them with rivets, bolts, etc., and a band-shaped metal plate with a protrusion in the center. What is claimed is: 1. A cover for protecting piping, comprising a coupling ring which is bent along the outer periphery of the pipe through the cushioning material and is bonded to the cushioning material. 2. A cover made of a metal plate that is externally fitted and fixed to the straight pipe part of the pipe without contacting the pipe, and is a cover made of a metal plate of the same width that is bent along the outer circumference of the pipe and formed in a bag-like fitting groove at one end. A plurality of short cylinders are formed into a cylindrical shape using a button punch method in which fitting protrusions formed at the ends are fitted and connected, and a band-shaped metal plate having a protrusion in the center is connected to the outer periphery of the tube via a cushioning material. What is claimed is: 1. A cover for protecting piping, characterized in that it is bent along the cushioning material and connected in the axial direction of the pipe via a coupling ring formed by adhering to the cushioning material.
