Steam Pipe Insulation Thickness Table

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.

Steam pipe insulation thickness table.

Fluid temperature range f conductivity range in btu inch per hour per square foot per f. In each table minimum insulation thicknesses are referenced for both pipe size and for operating temperature. T insulation thickness from table 120 3 a inches. Choosing the correct size.

Table 120 3 a pipe insulation thickness. Sizing steam pipes in si units. All steam steam condensate and hot water lines. Online calculator to quickly determine economical insulation thickness of steam piping.

In general 80 ft sec is a recommended steam velocity. Tables of schedule numbers can be obtained from bs 1600 which are used as a reference for the nominal pipe size and wall thickness in millimetres. Equations displayed for easy reference. In most new building construction the engineers will specify the thickness of fiberglass pipe insulation.

The minimum pipe insulation thicknesses are given in two tables 6 8 3a and 6 8 3b in the standard. This is by far one of our most popular commmerical uses of our fiberglass pipe insulation due to the large energy savings for building owners. In the new standard these tables are also reproduced in metric units. The insulation thickness is the wall thickness of the fiberglass which varies from 1 2 up to 3 thick.

Recommended insulation thickness of heating systems like hot water low medium or high pressure steam systems sponsored links to avoid heat loss and reduced system efficiency pipe work in heating systems should always be insulated. 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. Heating pipes steam steam condensate and hot water. There are two sizes you need to cho ose when ordering the pipe size and the insulation thickness.

This table below can be used for fast calculation of steam pipes sch. Steam pipes low to high pressure condensate lines. Table 10 2 1 compares the actual bore sizes of different sized pipes for different schedule numbers. The values are in figures 1 and 2 complete with the footnotes.
