Most common boiler steel pipe can be devided into two kinds, one is midium pressure boiler pipe, the other is high pressure boiler pipe. Please kindly note that most of high pressure boiler pipe are made from seamless steel pipe.
Boiler pipe has been widely used at heat exchanger pipe and tubing services, high pressure boiler, petrochemical industry pipes, tube exchanger bundle, economizer, super heater, etc.
Based on different working temperature, the medium or high pressure boiler pipe shall be used. Normally classified as below cases:
The operation temperature of general boiler pipe is lower than 450℃. The medium pressure boiler pipe mainly adopts hot rolling process or cold drawing process.
High pressure boiler pipe are often used in high temperature and high pressure working conditions. Under the action of high temperature flue gas and steam, the pipe will occur oxidation and corrosion. It is required high pressure boiler pipe that has high endurable strength, high oxidation corrosion resistance and good tissue stability.
