Guidelines
1 Nortec steam hose should only be used on short steam runs of less than 10 feet.
2 Ensure that no condensate produced in steam line will remain trapped. Steam naturally
flows upward and condensate naturally flows downward.
3 See material recommended for use in below chart. To eliminate metal corrosion, Nortec
does not recommend the use of steel piping.
4 Consult below charts for steam and condensate sizing guidelines when using steam
distributors.
5 Be sure to include fitting equivalent lengths in total steam run lengths (see below).
In general, match steam-line size to outlet size of distributor.
When using an SETC with less than 15 psig steam supply pressure, a reducer (Nortec part
number 2526110 – 3” to 1.5” reducer or 2526111 – 4” to 3” reducer) is required to
prevent over-sizing of steam lines.
All steam lines should be insulated with at least 1”-thick steam insulation.
