★‌Kub Rolling lossis Cold Drawing: Lub plhaub yog elongated thiab me me los ntawm precision dov lossis kos duab kom ua tiav qhov xav tau qhov ntev.

‌★Kev kho cua sov: Tubes undergoannealing, normalizing, los yog temperingkom optimize microstructure thiab mechanical zog.

★‌Kev Ntsuas & Kev Tshuaj Xyuas‌:

Txhua lub raj yuav raug:

1.Hydrostatic siab kuaj.

2.Eddy tam sim no los yog ultrasonic tsis pom kev.

3.Dimensional thiab nto zoo xyuas.

Cov ntawv thov thoob ntiaj teb
