Boiler flue
Thread Content
What standards are generally used for flue ducts through which the cooled flue gas from boilers passes? Is it based on the standard for ordinary steel pipes? I would appreciate some guidance from experts, thank you!
We directly welded it using steel plates with a thickness of 4 mm
What standard is used for the outer diameter? This kind of flue should be called a duct, right? It shouldn’t be called a pipe, right? Please give me some advice. Thank you!
The pressure is not high; the temperature is around 150°C. There is no proper design – it’s a square-shaped pipe, approximately 1000*1000 mm in size
Bends and elbows at the appropriate pressure and temperature can be used to weld them together into pipes
It’s much easier than using steel plates, and the flanged valves also allow for regulation
It can be processed in accordance with the requirements for manufacturing welded pipes specified in GB150.
