With the increasing use of large-diameter rolling pipes

Fang Gang is a kind of bar and is solid. In its production process,

It is also necessary to pay attention to the following points

A steel pipe generally obtained by honing process is called honing pipe.

Today we come to understand what are the characteristics of the production of cold drawn steel pipes.

High-precision cold-drawn pipe is a kind of steel pipe

Because high-precision cold-drawn tubes have good mechanical properties

Longitudinal rolling or cross rolling without small deformation of the mandrel on the rolling tube on the longitudinal rolling or cross rolling sizing machine

There are many people who do not pay much attention to the surface problems when choosing honing rollers.

Cylinder, if its expression is 16 × 320, it means that the cylinder bore is 16 mm

In fact, the work of the rolling tube is simple to reduce the surface roughness of the workpiece

During the quenching heat treatment of the cold drawn tube
