Annealing:

?

Spezilla offers the following thermal treatment processes to produce customers& acute; desired surface finish.

?

Bright Anneal: we utilize?annealing atmospheres, which create surface finishes that are free of heavy oxides or scales. The bright annealed final product has exceptional corrosion resistance and does not require post heat treatment pickling or grinding.


Open Air Anneal: Webco performs annealing in open air to create an oxidized surface finish. This oxide layer can either be left on the tubing, or it can be removed by grinding and polishing operations. The oxidized surface finish has been beneficial to some customers during forming of the tubing.


Grinding and Polishing:


Spezilla& acute;s manufacturing process includes the capability to grind and polish tube. These processes yield a tube with a smooth weld seam area and consistent tube body appearance.
