Method for improving accuracy of capillary wall thickness

Strictly follow the process requirements

The cold drawn tube is drawn by a mold of a certain shape and size under the action of force.

For the steel pipe without pre-treatment

The cold-drawn cylinder is made of hot-rolled tube.

The production characteristics of the cold processing tube unit

Cold-drawn steel pipe, cold-rolled steel pipe unit is a complete set of equipment for the production of pipes

During cold drawing, the steel pipe undergoes plastic deformation through a die of a certain shape

The cold drawn steel pipe is work hardened.

Cold drawn steel pipe is a kind of steel pipe

The cold drawn tube has no oxide layer on the inner and outer walls

Hot-rolled seamless steel tubes are generally produced on automatic tube rolling units.
