Steam Pipe Insulation Thickness Table

The insulation thickness is the wall thickness of the fiberglass which varies from 1 2 up to 3 thick.

Steam pipe insulation thickness table.

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. T insulation thickness from table 120 3 a inches. 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. 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.

Fluid temperature range f conductivity range in btu inch per hour per square foot per f. Choosing the correct size. Equations displayed for easy reference. Steam pipes low to high pressure condensate lines.

There are two sizes you need to cho ose when ordering the pipe size and the insulation thickness. Heating pipes steam steam condensate and hot water. In each table minimum insulation thicknesses are referenced for both pipe size and for operating temperature. This table below can be used for fast calculation of steam pipes sch.

Refrigerated chilled liquid pipes. The minimum pipe insulation thicknesses are given in two tables 6 8 3a and 6 8 3b in the standard. Sizing steam pipes in si units. All steam steam condensate and hot water lines.

The values are in figures 1 and 2 complete with the footnotes. In general 80 ft sec is a recommended steam velocity. Online calculator to quickly determine economical insulation thickness of steam piping. Table 10 2 1 compares the actual bore sizes of different sized pipes for different schedule numbers.

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. For full table with larger dimensions rotate the screen. In the new standard these tables are also reproduced in metric units. In most new building construction the engineers will specify the thickness of fiberglass pipe insulation.
