Instructions for use

·  In the following annealing process the remaining film of the drawing oil evaporates practically residue free

·  It is beneficial to purge the tubes with the protective gas prior to annealing

·  Drawing oil remnants in relevant solvents can also be removed easily

·  After the finishing pass, brass tubes can either be galvanised or, because of the bright surface, be used in the furniture industry.

·  Storage : Container to be stored under dry and frost protected conditions. Temperature range +5 °C to +60 °C
