The "Tubes for condensers and other heat exchangers for the operation of steam turbine plants" guidelines are currently split into three material groups (VGB-R 106e "Copper Alloys", VGB-R 113e "Stainless Steels" and VGB-R 114e "Titanium").

The guidelines are intended to provide information to the operating company of combined heat and thermal power plants so that they can order the correct piping for condensers and heat exchangers and also to help them prevent faults and damage. To allow a better understanding and to assess pipe damage, the guidelines contain material-specific explanations and information in the form of photos illustrating typical damage symptoms.
