Steam Pipe Insulation Thickness Table

All steam steam condensate and hot water lines.

Steam pipe insulation thickness table.

The insulation thickness is the wall thickness of the fiberglass which varies from 1 2 up to 3 thick. The values are in figures 1 and 2 complete with the footnotes. 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. The minimum pipe insulation thicknesses are given in two tables 6 8 3a and 6 8 3b in the standard.

There are two sizes you need to cho ose when ordering the pipe size and the insulation thickness. 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. Equations displayed for easy reference. Includes 53 different calculations.

In the new standard these tables are also reproduced in metric units. In each table minimum insulation thicknesses are referenced for both pipe size and for operating temperature. Heating pipes steam steam condensate and hot water. 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.

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. 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. In most new building construction the engineers will specify the thickness of fiberglass pipe insulation. T insulation thickness from table 120 3 a inches.

In general 80 ft sec is a recommended steam velocity. This table below can be used for fast calculation of steam pipes sch. For full table with larger dimensions rotate the screen. Sizing steam pipes in si units.

Table 120 3 a pipe insulation thickness. Online calculator to quickly determine economical insulation thickness of steam piping. 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.
