What is the DIN 17175 standard?

The DIN 17175 standard is a technical specification developed by the Deutsches Institut für Normung (German Institute for Standardization) for seamless tubes made from heat-resistant steels. These tubes are intended for use in high-temperature and high-pressure environments, such as in boilers, pipelines, and heat exchangers.

Two quality grades, I and III, are offered.

DIN 17175 Seamless Steel Tubes For Elevated Temperatures

DIN 17175 applies to seamless steel pipes. DIN 17175 Alloy Steel Pipes can be used to manufacture steam boilers, pipes, pressure vessels, and instruments operating at temperatures up to 600°C and at high temperatures. Due to the total load and special oxidation conditions, these pipes can be lowered or raised. High listed temperature limits.

Applications of DIN 17175 Tubes

DIN 17175 seamless steel tubes find extensive application in industries where heat exchange and fluid transport are critical:

  1. Power Generation: These tubes are widely used in boilers, superheaters, and heat exchangers within power plants, ensuring efficient energy conversion.
  2. Petrochemical Industry: DIN 17175 tubes facilitate heat exchange in processes like refining, distillation, and catalysis, contributing to the production of various petrochemical products.
  3. Chemical Processing: In chemical plants, these tubes play a crucial role in maintaining consistent temperatures during reactions and distillation.
