Why choose bright annealed tube?

1.Superior Surface Finish

The traditional annealing :Open furnace---Oxygen atmosphere---form Scale, tarnish the material,For more than 12m tubes this method is hard to clean inner surface.

A special bright annealing:Closed furnace---Insert atmosphere use noble gases(Nitrogen and argon)Preventing Oxygen to contact with material ---Surface finish is clean,bright and precision,which is an excellent starting point for further process,like electro-polishing and mechanical polishing. For more than 12m tubes,this method is much cleaner smoother on both inner and outer surface.

2.Better Mechanical Property

The temperature of furnace can reach more than 1350℃,and the tolerance for setting and real temperature can be controlled within +/-2℃,which is impossible for the traditional annealing.

3.Perfect Inspection Method And Inspection Equipment

100%PMI test

100%Hydraulic test

100%Inner cleaned by sponge

100%Dimension test

100%Surface test

Quality of precision drawn tubing is same to precision rolling.

4.More Precision Dimension

Advanced cold drawn technology from Japan and Korean,Making the close dimension controls.
