Usually, the dimensional tolerance of the bright precision tube can be guaranteed within 10 wires. Size can be customized. The production process of bright precision tube: round steel perforation - pickling - mill rolling - dimension measurement - delivery Ordinary precision tubes are easy to break during the bending process. Therefore, it is necessary to anneal the bright precision tube to improve the mechanical properties. The annealed precision tubes are called fine-rolled annealed seamless steel tubes, which are widely used in the production and processing.
