DIN 17175: Seamless Steel Tubes for Elevated Temperatures


Standard: DIN 17175
We can supply various grades of seamless boiler pipes, such as St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910, etc.

Applications

  • DIN 17175 seamless boiler tube is widely used in boiler industry, petroleum, chemical industry, chemical fiber, metallurgy, medicine, machinery, paper, heat preservation, refrigeration, mechanical equipment, food, electricity, water, construction, aviation, aerospace, marine, shipbuilding, environmental protection and boiler heat exchangers.
  • This seamless boiler pipe is also used for producing storage tanks of heat-resistant steels used in boiler-making and tool-making industries, and for constructing pressure reservoirs.
  • The seamless steel boiler tube is specially used as heating surface pipe in low and medium pressure boilers (The working pressure is not higher than 5.88 Mpa and the working temperature is below 450℃.). This seamless boiler pipe can also be used as heating surface pipe, economizer, superheater, reheater and petrochemical industrial pipe for high-pressure boilers (The working pressure is above 9.8 Mpa in general and the working temperature is between 450℃ to 650℃. ).

Size Range The size range of Bestar' seamless steel boiler tube is as follows:

  • Outer dimension is from 6.0 mm to 219.0 mm.
  • Wall thickness of DIN 17175 seamless boiler pipe ranges from 1 mm to 30 mm.
  • The maximum length is 12 m.

Competitive Advantages of DIN 17175 Boiler Tube

  • Bestar configures multiple inspection equipment and professional inspection personnel who have received rigorous pre-service inspection technician training. Only when they pass the appropriate examinations and obtain the corresponding qualification certificates, they can inspect seamless boiler pipes. We also conduct regular technical training to make them master the international advanced boiler tube inspection methods.
  • The production process is in accordance with circular comprehensive quality management system. We strictly control the production process and realize real-time monitoring of seamless boiler pipes.
  • Bestar does heat treatment for boiler tubes in accordance with the standard requirements. This treatment results in no oxidation layer on the surface. We also carry out kinds of inspections according to customers' requirements, such as eddy current inspection, magnetic particle testing, magnetic flux leakage testing, ultrasonic joint inspection and other inspections, in order to ensure stable performance of seamless boiler pipes. Our company also provides relevant inspection reports of boiler tubes.
  • According to customers' needs, Bestar can also provide other sizes or other grades of seamless boiler pipes.

Delivery Condition We deliver our seamless boiler pipes in the following conditions, such as hot rolled, cold worked, annealed, normalized and stress released states.
