Boiler tubes and heat exchanger tubes

A high temperature and pressure resistance, depending on the application – an increased or reduced heat transmission as well as good processing properties in regard to bending techniques are essential properties of boiler tubes and heat exchanger tubes.  

Thanks to our close business ties to leading steel tube manufacturers, we can, in addition to the standard grades EN, ASTM, ASME and AD, also supply special dimensions and grades such as Duplex, Super Duplex or Hastelloy, Incoloy and titanium alloys on short notice. Furthermore, we offer the complete range of processing techniques relevant in today’s market.
