Overview of precision cold drawn tubes:
Precision cold drawn tube (fine tube) is a high-precision steel tube material that uses cold drawn tube as the raw material for tolerance control and surface finishing. The precision cold drawn tube has the characteristics of high precision, high smoothness, good cleanness of the inner wall, high pressure and no leakage of the steel tube, no deformation of cold bending, flaring, flattening without cracks, etc., and can be used for various complex deformations and mechanical processing. The chemical composition of the precision cold drawn tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
The use of precision tubes:
Main uses: Automotive, motorcycle, refrigeration equipment, hydraulic parts, bearings, pneumatic cylinders, and other customers who have high requirements for precision, finish, cleanliness and mechanical properties of steel pipes.
Precision cold drawn tube difference:
1. The main feature of ordinary seamless steel pipe is that it has no welded joint and can withstand large pressure. The product can be very rough cast or cold drawn.
2, precision cold drawn tube is mainly the inner hole, the outer wall size has strict tolerance and roughness, the precision is extremely high.
