Low and medium-pressure boiler tubes are used for manufacturing a variety of low and medium-pressure boilers, overheat steam tubes, boiling water tubes, water wall tubes, etc. They are applicable to environments where the temperature is lower than 450℃. Their working pressure is usually no greater than 5.88Mpa. Such tubes are made of carbon steel pipes through hot rolling or cold drawing.
