DIN17175 is a heating surface pipes

DIN17175 is a federal German industrial standard, mainly used to stipulate the heating surface pipes, economizers, superheaters, reheaters, petrochemical boilers (working pressure is generally above 9.8Mpa, working temperature is between 450°C and 650°C) Manufacturing standards for industrial pipes, etc. The DIN 17175 standard also covers a variety of other steel pipe grades, such as St35.8, St45.8, 13CrMo44 and 10CrMo910, etc.

The chemical composition of steel pipes in the DIN17175 standard varies with different grades. Taking 15Mo3 (or 15MoG) as an example, its chemical composition mainly includes: carbon (C) content between 0.12~0.20%, silicon (Si) content between 0.10~0.35%, and manganese (Mn) content between 0.40 ~0.80%, the content of phosphorus (P) and sulfur (S) does not exceed 0.035%, while the content of molybdenum (Mo) is between 0.25~0.35%.

During the production process, the control of the chemical composition of steel pipes is crucial. By precisely controlling the content of each element, the performance and quality of steel pipes can be ensured to be stable and reliable. At the same time, the selection of production processes and parameter settings will also have an impact on the performance of steel pipes. Therefore, when producing DIN 17175 standard steel pipes, it is necessary to strictly comply with relevant standards and specifications to ensure that the quality and performance of the steel pipes reach the best level.

Steel pipes under the DIN17175 standard have the following salient features:

1. High quality and durability: It has excellent durability and can operate stably for a long time in harsh environments such as high pressure and high temperature.

2. Excellent heat resistance: It has excellent heat resistance. This allows them to maintain stable performance in high-temperature environments and not be easily deformed or damaged.

3. Precise chemical composition control: This standard precisely controls the chemical composition of steel pipes to ensure that the mechanical properties and corrosion resistance of steel pipes are optimal.

Steel pipes under the DIN17175 standard have a wide range of applications, mainly involving the following fields: Boiler manufacturing: used to manufacture heating surface pipes for high-pressure boilers, such as superheaters, reheaters, economizers, etc. Petrochemical industry: In the petrochemical industry, it is used to manufacture various pipelines, reactors, heat exchangers and other equipment. Its good corrosion resistance and high temperature stability enable steel pipes to cope with complex chemical reactions and high temperature environments. Electric power industry: In the electric power industry, it is used to construct key components such as superheaters, reheaters and main steam pipes of power station boilers. Used in thermal systems, metallurgical industry, shipbuilding industry, paper industry and other fields.
