Which steam trap is best for this application?
(OP)
I have 1250psi superheated steam as supply to a turbine. There are 400psi and 175psi saturated steam extraction lines coming off the turbine.
Which steam traps are best for the drip legs on each line? I am leaning towards sarco thermodynamic traps for all lines but the bucket trap looks appealing too.
All traps will be indoors so freezing is not an issue. I want traps I can socket-weld.
Thanks.

In addition to Spirax Sarco, also check out Armstrong Int'l. in Three Rivers Mich.
Hope this helps.

Condensate would go to a condensate receiver tank from where it would be fed into the condensate polishing resin beds.
Each of the 3 headers are approx 150' long. 400# header is 12". 175# header is 30". And the 1250# header is 18". Lines will be well-insulated so condensate loads should be relatively light during steady-state operation.
The manufacturers' websites seem fairly vague and even contradictory when it comes to recommending specific types of traps for certain applications.

More important than the type of trap is the design of the actual drip leg that the trap is installed on. The boot should be large enough to collect the water and the deep enough to allow seperation of liquid/gas. The trap should be off the side of the boot.

Now, I have my own question to ask; do you have provisions for start-up, and/or transient conditions when condensate loads might not be "light" or are you depending on the trap to do that for you as well?? That factor alone might well pick your trap for you.

For start-up conditions where condensate loads will be relatively heavy, operators will open manual valves to quickly evacuate condensate and air.
Our driplegs are large and well-designed.
