DIN17175 Seamless Precision Steel Tube 13CrMo44 Seamless Heat Exchanger Tubes
DIN 17175 boiler tubes
applies to seamless tubs including tubes for headers of heat-resistant steels according to standards that are used in the construction of boilers, pipe-lines, pressure vessels, and equipment for service up to 600 °C and simultaneous high pressures, where the total stress and the relevant scaling conditions can raise or lower the temperature limit.
Manufacturing process
Tubes to this standard shall be manufactured by hot or cold rolling, hot pressing, hot or cold drawing
The steels used for tubes shall be made by the oxygen-blowing process, the open hearth furnace, or the electric furnace.
All steels shall be killed.
