ISO 3183 L245B steel pipe manufacturing process

The manufacturing process for ISO 3183 L245B steel pipe may include the following steps and processes:

1. Raw material preparation: Select L245B grade steel plate or billet that meets the requirements of ISO 3183 standard as raw material.

2. Hot rolling production:
- Steel plate heating: Heat the steel plate to the appropriate temperature.
- Hot rolling: The steel plate is rolled into blank tubes by hot rolling machinery.

3. Perforation: The perforation machine is used to form a pipe hole in the center of the tube blank.

4. Hot extrusion: Through hot extrusion, the tube billet is further extended, heated and rolled to form ISO 3183 L245B steel pipe.

5. Heating treatment: Normalizing or annealing ISO 3183 L245B steel pipe to adjust its organizational structure and improve strength and toughness.

6. Cold processing: Through cold drawing, cold drawing and other processes, to further improve the dimensional accuracy and surface quality of the steel pipe.

7. Cutting: According to customer requirements or standard specifications, the steel pipe is cut to obtain products that meet the length requirements.

8. Inspection and quality control:
- Perform various tests on ISO 3183 L245B steel pipe, such as chemical composition analysis, mechanical properties testing, dimensional inspection, etc.
- Ensure that the product meets the quality requirements of ISO 3183 standard.

9. Surface treatment: clean, rust removal, anti-corrosion coating and other surface treatment to protect the steel pipe from environmental erosion.

10. Packaging and delivery: According to the requirements of the ISO 3183 L245B steel pipe packaging, and make the corresponding identification and records, ready to be shipped to the customer site or storage.
