Seamless Steel Tube for Low-pressure and Medium-pressure Boilers
The pipes for low/Medium Pressure Boiler service are used for over-heat steam piping and boiling water piping in low/medium pressure boilers and over-heat steam piping, and large/small of taker in boilers of lo-comotiver.
Low temperature service seamless pipes are application for low-temperature pressure container piping by the main standard GB/T18984-2003, ASTM/ASME A/SA333 with steel grade 16MnDG, 10MnDG, A333 Gr.1, A333 Gr.6, A333Gr.3.
GB/T18984-2003 standard suitable for -49 to -148 degrees F cryogenic pressure vessel piping, and low-temperature heat exchanger tubes Seamless Steel Pipe.
ASTM/ASME A/SA-333 Grades allow for cold temperature service to minus 150 degrees F. Material is always provided in the normalized condition at a minimum and Charpy Impact tested to a specific temperature range to assure compliance with the required service temperature.
