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---Intert atmosphere use
noble gases(Nitrogen and argon)Preventing Oxygen to contact with
marterial ---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
whithin +/-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.
