Includes use on elbows, tees, flanges, hangars and valves as explained below: (Valid only when used in conjunction with fiberglass insulation with a minimum k-factor of 0.25 BTU/hr-°F-ft2-in with weatherproof cladding). Use a minimum of 1" unless specified otherwise. For piping 2" and smaller in diameter use one single run of CRG05 cable. For piping between 2" and 4" in diameter, use one single run of CRG08 cable. For piping between 4" and up 5.5" in diameter use one single run of CRG10 Series cable. For piping greater than 5.5" and less than or equal to 6" in diameter use the CRG10 Series cable wrapped around the piping with a center to center spacing between wraps of 10" or less. For piping greater than 6" in diameter and up to 10" in diameter use a single run of CRG10 Series cable with a minimum of 2 inches of fiberglass insulation. For piping greater than 10" in diameter and up to 14"in diameter use a single run of CRG10 Series cable with a minimum of 2.5" inches of fiberglass insulation. For piping greater than 14" in diameter and up to 16"in diameter use a single run of or CRG10 Series cable with a minimum of 3.0" inches of fiberglass insulation.
