Tube hold by expansion in water tube boiler
Tube hold by expansion in water tube boiler
(OP)
Dear all
Typically tubes are held to the drum by tube expansion.
In what case does the tube (other than superheater, downcomer, and waterwall) need be held on the drum by welding?
Thanks
Aida

Thanks for your response. May I know at what pressure partial penetration welds are required?
Thanks
