What processes can make the inner diameter of ceramic pipes smaller?

Generally speaking, ceramic pipes can only increase their diameter because the inner wall can be ground slightly. However, the two processes introduced by Kezhong Ceramic Factory can reduce the inner diameter of zirconia ceramic pipes.

In the process of reducing the diameter of the inner hole of ceramic pipes, the process method of changing the pipe diameter mainly includes pipe sinking and reducing the framework of the coreless rolling process of the pipe rolling mill. There are generally two methods.

One is the operation during tube heating:

1. Tube tension-free reducing machine: a framework for reducing the tension during the rolling process of hollow tube mills without core rods, with the aim of obtaining long tubes and small diameters to expand product specifications and improve unit production capacity. The tension free reducing machine and the longitudinal rolling sizing machine are the same, but the number of grinding frames is reduced by 15-22.

2. Tube tension reducing machine: A continuous method of belt tension is used to reduce the frame without a core rod in a hollow tube mill, with the aim of obtaining both reduced and reduced wall finished tubes. The tension reduces the total wall thickness variation by -30% to+30%, so some specifications of pipelines can be used to produce specifications through tension reducing steel pipe mills.

The second is low-temperature operation:

Tube cooling reduction: A method of reducing the diameter of a tube at room temperature, where the deformation process involves similar heat dissipation. When cold is the basic characteristic of reducing the stability and deformation of the workpiece cross-section, it is not easy to experience rolling and folding.
