Chilled water pipe insulation thickness table.

Pipe unions in heating systems steam steam con densate and hot water. Insulating chilled water systems requires special attention. The table below indicates recommended insulation thickness. In general there are no insulation thickness requirements for residential domestic hot water pipes but we find that 1 thickness will greatly reduce the loss of heat transmission.

When piping and equipment. Section 120 3 requirements for pipe insulation. For example 1 in. All penetrations and joints of which shall be sealed.

Wall thickness insulation 3 8 in 46 1 2 in 124 3 4 in 96 1 in 219 1 1 2 in 58 2 in 50 insulation length. Water pipe insulation the following piping shall be insulated to levels shown in section 6 table 6 8 3. T insulation thickness from table 120 3 a inches. Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs.

This calculation determines the ideal thickness of water piping insulation for efficiently and economically preventing a heat transfer from outside to inside and keeping the water transported within cool it does not determine the thickness of insulation designed to keep condensate or other fluids from losing heat. Insulation covering chilled water piping and refrigerant suction piping located outside the conditioned space shall have a class i or class ii vapor retarder. Pre slit polyethylene pipe insulation. For below ambient service by contrast the new pipe insulation thicknesses are not particularly noteworthy.

Range f insulation conductivity nominal pipe or tube size in conductivity. 2 0 role of pipe insulation for chilled water systems 33 f to 60 f 0 5 c to 15 6 c pipe insulation for chilled water systems is specified and installed primarily for process control condensation control and energy conservation. D recirculating system piping including the supply and return piping of a circulating tank type water heater. Use of 1 1 2 or 2 thick fiberglass pipe insulation will most likely not be cost effective on domestic hot water unless the size of the pipe is greater than 3 ips.

Very hot systems like hot water and steam systems should also be insulated to avoid potential personal injuries. Delete existing table 6 8 3 in its entirety and replace with tables 6 8 3a and 6 8 3b addendum bi to 90 1 2007 table 6 8 3 minimum pipe insulation thicknessesa fluid design operat ing temp. Table 6 8 3a minimum pipe insulation thickness.
