Figure 10: Main Steam Line Requirements
MAIN RULES FOR ATMOSPHERIC STEAM LINES
 Steam lines must not have any restrictions which could result in back pressure.
 Follow recommended materials, size and length, see tables.
 Slope the steam lines.
 Insulate with 1.0 in. (2.5 cm) pipe insulation
 Trap condensate (Use full size ‘T’ for Traps)
 Do not over tighten hose clamp at cylinder steam outlet. The maximum torque is 12
in-lbs.
 Support steam line so weight is not on cylinder.
 Condensate traps must be a minimum of 6 in. (15 cm) in height or duct static
pressure + 2 in. (5 cm), whichever is greater.
 Trapping by P-trap or pigtail. Support line as necessary to ensure it remains free of
kinks.
