4. Manufacturing process of SA210C steel pipe
The manufacturing process of SA210C steel pipe mainly includes the following steps:
4.1 Raw material preparation: Select appropriate raw materials for pipe making. Commonly used raw materials include hot-rolled steel billets, cold-drawn steel pipes, etc.
4.2 Heating treatment: Heating the raw materials to the appropriate temperature to improve their plasticity and processability.
4.3 Perforation: Perforation is performed on the heated raw material, and the raw steel billet is processed into a tube shape through a punching machine.
4.4 Hot rolling: The perforated tube blank is hot rolled, and the tube blank is gradually lengthened and thinned through the action of the roller table.
4.5 Final rolling: Final rolling is performed on the hot-rolled tube blanks to obtain the required specifications and dimensions.
4.6 Testing and packaging: Carry out quality inspection on the finished SA210C steel pipe, such as chemical composition analysis, mechanical performance test, etc. After passing the test, it will be packaged and shipped out of the factory.
