use cases
- 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).
