Seamless heat‑resistant alloy steel tubes manufactured to DIN 17175 in grade 13CrMo44, engineered for demanding high‑temperature and high‑pressure environments (service temperatures up to 600 °C). These tubes are produced as seamless pipes to ensure uniform mechanical properties and long‑term creep resistance required for boiler, pressure‑vessel and pipeline applications.
Key features
- Standard: DIN 17175
- Steel grade: 13CrMo44 (heat‑resistant alloy for elevated‑temperature service)
- Service temperature: up to 600 °C (depending on design and operating conditions)
- Manufacture: seamless construction for improved integrity under pressure and thermal stress
- Surface finish: supplied oiled or black‑painted to prevent rust during storage and transit
- Marking: per customer requirements
Available supply and processing options
- Heat treatment (full length as required): normalizing, subcritical annealing, hardening and tempering with continuous cooling, or hardening and tempering with isothermal treatment — selected according to the steel type and customer specification
- Sizes: available in a range of diameters and wall thicknesses (wall thicknesses up to 28 mm are offered); final dimensions, tolerances and lengths supplied on request
- Quality control: tubes are produced under controlled metallurgical and process conditions; inspection and test documentation can be supplied as required for B2B projects
Typical applications
- Construction of boilers and superheaters
- High‑pressure and high‑temperature pipelines
- Pressure vessels and headers
- Any equipment requiring heat‑resistant steel for operation at elevated temperatures and simultaneous high pressures
Ordering information
When requesting a quotation, please provide: required standard (DIN 17175), outer diameter and wall thickness, length per piece, quantity, required heat treatment, surface finish and any marking or certification requirements. Technical datasheets, mechanical/chemical test reports and special inspection certificates can be provided upon request to support procurement and qualification.
