Correct - with a small adjustment. Supplier (me) is "Stack Engineering / Manufacturing / Fabricating". i.e we are not just a steel supplier. Customer 2 will purchase an Engineered Stack from me and we will deliver it to Customer 1 / 2 at the job site.
Thanks all for chiming in. I've never been to this site and great support.
Our customer, a boiler manufacture, sold an "A-36" exhaust stack as part of their package to their customer, a Canadian petrochemical company. This boiler supplier offered a higher grade material for the stack but that...
Thanks for the very detailed replies!
Dhengr- normal operating temperature of the stack is 400F. Of course the -46 C will only occur when the unit is not operating and during an extremely cold day.
The job site is near Edmonton Canada.
Thanks for the replies.
ASME STS 1 Steel Stacks is what governs stack designs and they don’t address cold weather material selection or what temperature charpy testing is recommended.
ASME STS - 1 Steel Stacks does not address this issue.
There is a requirement from the client to charpy test lifting lugs and weld procedures at -46C.
Correct the client specifies a minimum design temperature of -46C and A-36 materials.
It still comes down to 1) Is A-36 an acceptable material...
Don't know if this should be in the Structural Engineer or Materials section.
The project is a self supporting stack that would be behind a natural gas fired boiler.
We always use A-36 material but are aware of brittleness at low temperatures.
Is there a general "rule" when to switch to a...
