Boiler pipe problem?
Boiler pipe problem?
(OP)
A 400 HP boiler steam outlet connection. A pipe connection of 6" diameter with a pressure of 150 psi and 366 F. I am trying to find out if sch 40 will be resist the pressure it will be given or should it be switched to a sch 80.
Thank you
Thank you

That being said, if you're using steel piping, chances are sch 40 piping will handle your pressure requirements with a lot to spare. The flange rating is generally the limiting factor in this pressure range.
A heads-up. If this is boiler external piping make sure you get the right pipe - SA-106 gr. B vs A-106 gr. B, etc.
One more thing - why is the pipe wall being questioned in the first place? Did you have a failure of some kind?
Good luck

It seems that your condition is condensate near saturated steam. Please check the design condition.

You are right. I worry for mechanical design. Normally for the design and operating conditions are difference. I always use the slightly superheated condition for the design.
Thanks for your advice.
