MTSCO has been dedicated to producing bright annealed tubes since
2014 , owning complete producing technology and abundant managing
experience . And the raw material such as mother tube , round bar
we use is from Chinese biggest and well-known steel mill : Walsin ,
Yongxing etc . Also we have advanced NDT equipments for the tests
such as Eddy Current test , Ultrasonic test , Hydraulic test and so
on . Welcome you contact us in free !
Stainless steel seamless bright annealed tube’s final surface is
polished and bright annealed. And the polished grade is includes
180 # , 320 # , 400 # , 600 # , 800 # . According to standard very
strictly , tubes which produced by us always have correct OD and WT
tolerance. And they are very suitable for chromatography industry.
