Precision seamless steel tube for hydraulic and pneumatic cylinder which belongs to cold drawn or cold rolled type with precise inside diameter can be applied in the transmission of fluid like water, fuel and gas.

As adopting quality hot rolled steel tube produced by BAOSTEEL as ingot while being in accordance with the production standard, DIN2391/EN10305, the product can be processed into the precision seamless steel tube with high precision and good fineness by accurate and unique cold drawn/cold rolled technology. Trough the glazed hot treatment with oxygen free medium as protective atmosphere, no oxide skin(film) may appear inthe internal or external surface of finished product. Due to that, no only the original dimension, precision and cleanliness can be maintained but also the performance of steel tube shall be improved which is suitable for different deep processing. It can be applied to fuel, gas(air brake) and liquid systems of manufacturing industry of different vehicles including car, coach, rolling stock(locomtive) and varied engineering machineries (like digger, bulldozer, overhead wording truck, sweeper, concrete pump truck and others) as well as in hydraulic tube fitting system for different hydraulic machinery. It shall be especially suitable for different ferrule joint connections; and the effect of which can be far better than the traditional weding connection. It can replace the imported seamless steal tube at the same standard completely.
