Heat Treatment
We are equipped to carry out heat treatment of bends plus a minimum 150mm of leg.
Heat treatment equipment is computer controlled with the added facility of data recording.
An argon protective atmopshere is used inside stainless and special alloy tubes during heat treatment.
We can provide all types of annealing; solution annealing and stress relieving.
Measuring, Cutting, Deburring and Cleaning
'U' bends are produced, controlled and measured fully in accordance with relevant standards.
All tubes are cut to the specified leg lenghts, ends deburred and the bores are internally cleaned with dried air.
Packing
For roadfreight in timber fingers or skids.
In strong open or closed wooden boxes depending destination.
Each bundle is protected with plastic sheets.
Customers can provide their own packing or Spezilla can prepare a packing plan.
Detailed packings lists are attached to wooden cases to give quick and clear identification of contents.
