In comparison to classic joining methods, the cold pressing of tube joints has numerous advantages in the application. Installers value the quick, convenient and reliable installation that is also possible in difficult to access spaces. In addition, the large number of available tube dimensions give fitting manufacturers and end customers maximum flexibility so they can offer and realise tailored solutions.

Tube requirements

  • Excellent formability
  • Homogeneous strength and elongation
  • Minimised fluctuations in wall thickness
  • Very good weld seam quality
  • Homogeneous, fine-grain microstructure in weld seam
  • and basic material
  • Excellent welding properties
  • Excellent surface condition (internal and external)
  • Minimised surface discontinuities (adhesions, scratches, dents etc.)
