Shanghai Zhongze Yi Metal Materials Co., LTD. Stainless steel pipe production process:
1. Raw material preparation: The production of stainless steel pipes begins with the selection of high-quality stainless steel raw materials, usually made of iron, chromium, nickel, manganese and other elements of the alloy.
2. Melting: Raw materials are heated to high temperatures, through the process of melting, so that it becomes a liquid metal.
3. Tube blank preparation: Pour the melted metal into the mold to form the tube blank.
4. Perforation: Through the perforation machine, the tube blank is heated and rotated, so that it forms pipe holes on both sides of the inside and outside.
5. Extrusion or stretching: By extrusion or stretching, the tube blank is gradually thinned to form a seamless tube.
6. Pickling: pickling the pipe to remove surface oxides and impurities.
7. Cold drawing or cold rolling: cold drawing or cold rolling of the pipe to improve the accuracy and surface finish of the pipe.
8. Annealing: Through heating treatment, eliminate the internal stress and improve the physical properties of the pipe.
9. Cutting and sizing: the pipe will be cut to the appropriate length according to customer needs.
10. Testing and packaging: the quality of the pipe is tested, including size, chemical composition, etc., and then packaged.
Introduction of stainless steel pipe:
Stainless steel pipe is a kind of corrosion-resistant, high-strength metal pipe, because of its excellent corrosion resistance and high temperature resistance, widely used in petroleum, chemical, pharmaceutical, food industry and other fields. Stainless steel pipe is divided into two kinds of welded pipe and seamless pipe, according to the use and requirements of different, choose different production process.
Advantages of stainless steel pipe:
1. Corrosion resistance: Stainless steel pipes have excellent corrosion resistance and can maintain their performance in harsh environments for a long time.
2. High strength: stainless steel pipe has a high strength, suitable for withstand high pressure and large load occasions.
3. High temperature resistance: stainless steel pipe maintains strength and durability in high temperature environment, suitable for high temperature process and transportation.
4. Health and safety: Due to the smooth surface of stainless steel, it is not easy to attach dirt, so it meets health standards and is suitable for medicine and food industry.
Application of stainless steel pipe:
1. Oil and gas industry: used to transport oil and gas, petrochemical equipment.
2. Chemical industry: Used to manufacture chemical equipment, pipes and containers.
3. Medicine and food industry: due to good hygiene, it is used to manufacture medical equipment and food processing equipment.
4. Building and structural engineering: used to make building structures, handrails, stairs, etc.
5. Automobile manufacturing: Used to manufacture automobile exhaust pipes and other parts.
Shanghai Zhongze Yi Metal Materials Co., Ltd. is committed to providing high-quality stainless steel pipe products, through advanced production process and strict quality control, to provide customers with reliable stainless steel solutions.
