 2)Specification,

 size:OD0.2-10mm,Thickness:0.1-1.5mm,Other sizes could be customized .

We can do stainless steel pipe's deep-processing,such as Stamping,Punching holes,Welding,etc.

 3)Technology

Advanced precision welding machines, disc machine, high production efficiency, good product consistency, pipe size precision, it can be compete with seamless pipe, the price is more favorable.

 4)Testing equipment and instrument

 We have all kinds of mechanical equipment and experiment of physical chemistry experiment

equipment, Each batch of pipes through rigorous testing.
