| Commodity hot-sales features |
Cold Drawn Production Process Method Seamless Steel Pipes is one of our hot-sale commodities, which is newly developed these years. Due to cold rolling products' features like good precision size and bright surface, it is getting more and more attention and acception from cleints. We are giving its magnificent advantages as follows:
Main Advantages of cold rollong precision steel pipes:
A. High precision size and much smaller tolerance, this pipe is produced under cold drawn process method. The pipe OD and ID tolerance can be with -0.15/+0.15mm. There is no oxide skin layer on both inside and outside surfaces, degree of finish is very well.
B.High precision cold rolling seamless steel pipes have good comprehensive mechanical property. It can bear high pressure, cold bending, expanding, pressing flat without crack, and other complex size change and mechanical handling.
C.High precision cold rolling seamless steel pipes being used largely will help save the steel materials, promote the machining efficiency, reduce the expense and decrease processing time on large extent.
So this kind of pipes are widely as deformed bar connection, automobile components, mechanical engineering parts, hydraulic fittings, peneumatic components, oil cylinder, boiler equipment and so on.
