The material of the cylinder tube is mainly made of hot-rolled seamless steel tube

When changing rolls, first check the rolls, do not use severely corroded rolls

The pitting of the quilting tube is characterized by the uneven surface of the product

The characteristics of the rolling tube are as follows

High-precision cold-drawn tubes require maintenance

Mainly process cylindrical holes: through holes, axial and radial intermittent holes

High processing accuracy

The basic processes of cold-rolled and cold-drawn tubes are

The complete equipment combination for the production of pipes using cold rolling

Under normal circumstances, there will be little holes on the surface of these parts

In the shedding and cutting stage of honing tube processing

Even if the high-precision cold-drawn tube is processed
