[0002] When steel pipes are produced, internal and external grinding operations are often required. Internal and external grinding is a steel pipe processing process, which is mainly used to process the inner and outer surfaces of steel pipes. This process usually involves the use of professional grinding equipment, such as internal and external weld grinding machines, to remove uneven parts of the steel pipe surface to achieve a specific surface roughness and dimensional accuracy.

However, when grinding the inner surface of the steel pipe, the steel pipe is often rotated within a certain range, and then the grinding head is inserted into the steel pipe for grinding. The dust generated by grinding cannot be sucked out in time, which can easily cause environmental impact when the steel pipe is moved to the back-end process. Utility Model Content
