BS 3059 II 440 requirements specification for carbon, alloy and
austenitic stainless steel tubes with specified elevated
The method of manufacturing boiler tube is the same with seamless
steel pipe,but this pipe has a requirement of the steel grades.
Depending on the operating temperature, it can be divided into two
kinds: general boiler pipes and high-pressure boiler tubes.
A general boiler pipe is able to work below the temperature
450°C.It’s made of hot finished or cold rolled carbon steel pipes.
While high-pressure boiler tube is used to produce high-pressure or
ultrahigh pressure super heater tube,reheater tube,gas-guide
tube,main steam pipe and so on. Our product BS3059-II 440 belongs
to this boiler tube.
Size range of BS3059-II 440 boiler tube
- Out diameter:19.05-114.3mm
- Wall thickness:2-14mm
- Max length:16m
