Abstract:
A pipe insulation coupling for coupling adjacent ends of elongated pipe insulation tubing comprising:an elongated body extending along a longitudinal axis between a first end and a second end, said elongated body including;a cylindrical outer tube wall extending along said longitudinal axis between said first end and said second end,a cylindrical inner tube wall spaced inwardly from and generally parallel to said outer tube wall and extending along said longitudinal axis between said first end and said second end, said inner tube wall and said outer tube wall defining an elongated channel therebetween adapted to receive adjacent ends of pipe insulation tubing,a planar wall positioned transverse to said longitudinal axis for interconnecting said outer tube wall and said inner tube wall midway between said first and second ends and adapted to abut the adjacent ends of the pipe insulation tubing, andat least one of said outer tube wall and said inner tube wall having a tapered inner surface extending from said planar wall to each of said first and second ends for gradually decreasing the space between said outer tube wall and said inner tube wall defined by said channel to frictionally retain the adjacent ends of the pipe insulation tubing within said channel along opposing sides of said planar wall.
