2 - INSTALLATION
8. High point bleeds/air vents are to be installed at
all high points in the system piping.
9. All pipes should be installed with a pitch to
facilitate draining and venting.
(Boilers with a maximum operating pressure of 125 psig, 150 psig max. trim pressure)
Service
Blowoff
Water bottle nipples
Note: downstream of the water bottle
drain valve to follow surface blowdown
piping requirements
Surface Blowdown Piping
Condensate (i.e., any piping that may
come in contact with the condensate that
is not deaerated – water piping).
Feedwater – between the pump and the
boiler/steampac++
Pump Recirculation orifice piping
Steam Headers/Deaerator steam piping to
125 psig incoming steam pressure+++
Overflow/Drain piping (water) including
DA liquid drainer piping
Blowdown tank drain and outlet piping
100% fresh cold water make up (including:
DA tanks, water softener, etc)
Note: Piping within the boiler's ASME code piping boundary supersedes the information in this table.
++ If there is no preheat in the feedwater tank, feed water piping between the feedwater tank and the boiler should be sch 80, SA 106B.
+++ Welded/flanged pipe (3" and greater) may be sch. 40.
