Chilled water pipe insulation thickness table.

To avoid heat loss and reduced system efficiency pipe work in heating systems should always be insulated. 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. Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs. The table below indicates recommended insulation thickness.

Pre slit polyethylene pipe insulation. T insulation thickness from table 120 3 a inches. Table 6 8 3a minimum pipe insulation thickness. Very hot systems like hot water and steam systems should also be insulated to avoid potential personal injuries.

For below ambient service by contrast the new pipe insulation thicknesses are not particularly noteworthy. D recirculating system piping including the supply and return piping of a circulating tank type water heater. 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. All penetrations and joints of which shall be sealed.

Range f insulation conductivity nominal pipe or tube size in conductivity. Pipe unions in heating systems steam steam con densate and hot water. For example 1 in. Section 120 3 requirements for pipe insulation.

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.

Water pipe insulation the following piping shall be insulated to levels shown in section 6 table 6 8 3. 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. Is sufficient thickness for all sizes on chilled water lines with an assumed operating temperature in the 40 f to 60 f range.
