Einsatzbeispiele

Application limits<br />Quality grades I: Tubes with OD ≤ 63.5 mm are for temperature of conveyed fluid ≤ 450°C and permissible working pressure p ≤ 80 bar; Tubes with OD > 63.5 mm are for temperature of conveyed fluid ≤ 450°C and permissible working pressure p ≤ 32 bar<br />Quality grades III: Tubes with OD ≤ 63.5 mm are for temperature of conveyed fluid > 450°C and permissible working pressure p > 80 bar; Tubes with OD > 63.5 mm are for temperature of conveyed fluid > 450°C and permissible working pressure p > 32 bar.<br />Used in the construction of boilers, pipelines, pressure vessels and equipment for service up to 600°C and at simultaneous high pressures, where the total stress and the relevant scaling conditions can raise or lower the temperature limit.
Mainly intended for use in chemical plants for high pressure applications at service temperatures of 200°C or more and simultaneous exposure to hydrogen (e.g. boiler or heat exchanger tubes).
