Propane Pipe Sleeve Torch, 1975. Steel and brass propane torch. The cylindrical head of the torch is 5” long with a 1.5” diameter. The torch head has multiple air holes including four 3/8" diameter holes spaced equidistant around the circumference near the base. Six rows, each comprised of six 1/4 inch holes, appear down the length of the torch head and are spaced at 0.5” apart from each other around the circumference. The torch head is attached to 0.5” diameter metal tubing that is bent at a 30 degree angle a few inches below the head. After the bend, the tube extends for 10 inches where a brass valve is attached to regulate the flow of gas. A black sleeve of heat shrink plastic covers the lower 7.5" of tubing.
This torch was used by Jim Thompson during the Trans-Alaska Pipeline construction project. His role was to show workers how to correctly install Raychem Corporation products and teach quality control inspectors the criteria for correct installation. He notes that when in use, the torch was connected to a propane bottle with a regulator via a 20 foot hose to distance the flame from the gas tank. The valve at the bottom of the torch releases gas up through the pipe to a small nozzle at the head. When ignited, the flame extends approximately 6 feet long and several feet in diameter. Torches were used to repair local area damage that resulted when heated wrapped pipe sections were placed on skids to cool down, and to install heat-shrink pipe sleeves over tie-in joints.
