BS 3059-2:1990 requirements for tubes not exceeding 127 mm outside diameter and 12.5 mm thickness. Depending on the operating temperature, it can be divided into two kind’s general boiler pipes and high-pressure boiler pipes.
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 pipes.
