What is the wall thickness error of steel pipe
The wall thickness of the steel pipe is not the same, different uses have different wall thickness, for many aspects of the wall thickness of the steel pipe is also has different errors, according to the production technology, production requirements, performance reflects the wall thickness of the city has different errors, as long as it is in a reasonable extent, the steel pipe will not affect the use and performance of the play.
The actual wall thickness deviation of steel pipe has several aspects:
1. Deviation during the perforating process of the perforator.
2. Equipment manufacturing precision and structure
3. Installation and adjustment of equipment cables
4. Heating process of tube blank
5. Blanking of tube blank
6. Influence of tool accuracy
7. Use an automatic pipe mill
