Chilled Water Pipe Insulation Thickness Table

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.

Chilled water pipe insulation thickness table.

Section 120 3 requirements for pipe insulation. Is sufficient thickness for all sizes on chilled water lines with an assumed operating temperature in the 40 f to 60 f range. For below ambient service by contrast the new pipe insulation thicknesses are not particularly noteworthy. Insulating chilled water systems requires special attention.

T insulation thickness from table 120 3 a inches. 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. Table 6 8 3a minimum pipe insulation thickness. Pipe unions in heating systems steam steam con densate and hot water.

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. View more view all jump to. 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. D recirculating system piping including the supply and return piping of a circulating tank type water heater.

To avoid heat loss and reduced system efficiency pipe work in heating systems should always be insulated. Very hot systems like hot water and steam systems should also be insulated to avoid potential personal injuries. Pre slit polyethylene pipe insulation. When piping and equipment.

All penetrations and joints of which shall be sealed. 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. Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs. Water pipe insulation the following piping shall be insulated to levels shown in section 6 table 6 8 3.

The table below indicates recommended insulation thickness. 6 7 bs5422 table table referencepage no 6 minimum insulation thickness for chilled and cold water steel pipes to control condensation on a high emissivity outer surface 0 9 with an ambient temperature of 25 c and a relative humidity of 80. For example 1 in.
