DIN 17175 13CrMo44 Steel Seamless Boiler Tube High Pressure Application

 

 

DIN 17175 seamless boiler tube cover several grades: St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910. DIN 17175 13CrMo44 seamless boiler tubes are heat-resistant steel tubes commonly used in construction projects, such as boilers, pipelines, and pressure vessels, where high-temperature resistance and durability are essential. 

 

 

DIN 17175 Steel Seamless Tube Manufacturing process:

A. Hot Rolling:

  • A billet (solid cylindrical steel block) is heated to a high temperature.
  • The billet is pierced and elongated into a hollow shape with the help of a mandrel.
  • The tube is rolled into the specified dimensions and reduced for uniform wall thickness.

B. Cold Drawing (Optional):

  • To achieve precise dimensions or finer surface finishes, the hot-rolled tubes may undergo a cold drawing process.
  • In this process, the tube is pulled (drawn) through a die to reduce its diameter and achieve tighter tolerances.
