What is Boiler Tube?

Boiler tube is a kind of seamless steel pipe. The manufacturing technology is the same as the seamless pipe, but it has strict requirements for the steel grades. According to the applications, boiler tubes can be divided into low or medium pressure boiler tube and high pressure boiler tube.

Product Name: Boiler Tube
Steel Grades:
High quality carbon steel: 20G、20MnG、25MnG
Alloy steel: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB etc.
Standards:
