Pipe Thermal Insulation Thickness

Inches recommended minimum thickness of insulation inches.

Pipe thermal insulation thickness.

Temperature range oc 50 90. Thicknesses of thermal pipe insulation used for saving energy vary but as a general rule pipes operating at more extreme temperatures exhibit a greater heat flow and larger thicknesses are applied due to the greater potential savings. The location of pipework also influences the selection of insulation thickness. Fiberglass pipe insulation and accessories are an ideal solution to meet or even exceed commercial and industrial project requirements.

This very rigid insulation offers the lowest heat flow rate of our pipe insulation and restricts absorption of water air and gas. Is sufficient thickness for all sizes on chilled water lines with an assumed operating temperature in the 40 f to 60 f range. It is typically used in process piping and chiller plants and performs best in applications below 50 f. Personnel protection burn protection.

Very hot systems like hot water and steam systems should also be insulated to avoid potential personal injuries. Thickness 305 7 203 2 102 5 mm some margin should be taken on the insulation thickness because if the conductive heat transfer rate happens to be higher than the convective heat transfer rate outside the insulation wall the outer insulation wall temperature will shoot up to higher values than 50 0 c. Minimum thicknesses to meet ashrae 90. The table below indicates recommended insulation thickness.

The pareto solution with thicker insulation thickness 20 cm in the south facade and 21 cm in all the other surfaces is the one presenting lower effect on the human health caused by ionizing radiation which is at the same time the worst from the carcinogenics impact and the economic cost standpoints. Pipe insulation plays an important role in the design and construction of buildings where pipe temperatures can range from 0 f to 1000 f 18 c to 538 c in copper iron pvc cpvc and stainless steel piping. Insulation thickness 77 7 mm. Extra margin must be taken on insulation thickness as sometimes conducting heat transfer through insulation may become higher than convective heat transfer due to air on outside wall of insulation.

For example 1 in. For below ambient service by contrast the new pipe insulation thicknesses are not particularly noteworthy.
