Extracting, pressure forming, sawing, cutting, hammering, bending:
some pipes need this.

Even if some materials tests are “destructive”, they naturally do not affect the entire pipe order batch. Instead, random inspections are carried out. However, these are very important if specific pipe characteristics cannot be inspected in another way. Will the component be mechanically or thermally tested? That depends on the planned use of the pipe, as well as the applicable standards and technical regulations. To enable you to specify the application limits of your material, our highly qualified partner companies determine the mechanical, chemical and metallographic characteristics of seamless pipes.

Mechanical-technological material testing:

  • Tensile test
  • Hot tensile test
  • Compression test
  • Impact test
  • Energy release rate
  • Hardness test based on Brinell, Rockwell or Vickers
  • Hardness test based on the UCI procedure (ultrasonic contact impedance)
  • Technological testing (dynamic-mechanical analysis and roughness measuring)
  • Flattening test
  • Ring expanding test
  • Ring tensile test
  • Drift expanding test

Materialography and analysis, such as:

  • Reflected and transmitted light microscopy with a scanning electron microscope, DIC, polarisation
  • Image and pore analysis
  • Determination of the purity grade, grain size and structure
  • Damage analysis
  • Corrosion tests, stability against intergranular corrosion and pitting corrosion
  • Test in the field of classic metallography

Analytic material testing, such as:

  • Determination of all important chemical elements
