Super Duplex 2507 Pipe Hot Rolling Production Process:
1. Raw material preparation: Firstly, the raw materials needed for duplex stainless steel 2507 pipe production need to be prepared, including iron ore, alloy, and other auxiliary materials.
2. Smelting and casting: The above raw materials are smelted and cast to form the base material of the super duplex 2507 pipeline.
3. Billet hot rolling: After heating the steel billet to a certain temperature, hot rolling is carried out to process the base material into the required pipe shape.
4. Pickling: Pickling the surface of the hot-rolled pipe to remove surface oxides.
5. Diameter straightening: straighten the diameter of the super duplex 2507 pipe to ensure that the pipe diameter is consistent.
6. Annealing treatment: Annealing the pipe to eliminate stress and defects in the hot rolling process and improve the mechanical properties of the pipe.
7. Gas-shielded welding: Use gas-shielded welding technology to weld the joints of the pipeline to ensure the quality and reliability of the entire pipeline.
8. Bright annealing: Bright annealing treatment is carried out on the welded pipes to obtain good surface cleanliness.
9. Surface treatment: Surface treatment of S32750 super duplex pipe, coating with anti-corrosion layer, etc.
10. Hydrostatic test: Carry out hydrostatic test to ensure the reliability and safety of the pipeline.
11. Packing and shipping: Pack the super duplex 2507 pipes according to the specifications, and have a special person conduct a quality inspection, and finally ship to the customer.
