Title: Pipe Shield A Device For Protecting Piping From Inadvertent Damage During Construction or Demolition Operations A device is described for protecting adjacent gas lines which may be carrying toxic or dangerous gases from damage during construction or demolition activities. Although configurable for other uses, the prototype depicted in the attached photographs is designed to fit on the 1” outer jacket of a coaxial toxic gas line. As shown in the accompanying figures, the prototype shield is comprised of a 4” long X 21/2” wide X 1/16” thick piece of tool steel which is rolled to conform with the radius of the pipe, and provide approximately 180 degrees of coverage. The shield is heat treated to provide a surface slightly harder than the hardness of a power hacksaw blade. The shield is attached by means of a tubular rivet to a spring clip rolled to conform to the radius of the pipe. The clip provides a snug fit while allowing the shield to slide along the pipe or be rotated around the circumference of the pipe. When installed, the shield requires virtually zero clearance and therefore creates minimal interference with the construction/demolition activities. The shield face is oriented so that it protects the pipe from saw cuts or incidental contact with welding electrodes. Shields can be installed on any piping that could be subject to incidental damage while construction or demolition is being performed on an adjacent line. Slight modification of the design, such as cutting one end on a 45 degree angle could allow full coverage at elbows by installing two pipe shields so that the 45 deg. ends over lap. The shield can be fabricated to fit any diameter pipe.
