First, the chemical composition and performance characteristics of 06Cr17Ni12Mo2N stainless steel seamless pipe
The products of 06Cr17Ni12Mo2N stainless steel seamless pipe should comply with the requirements of TSG D7002 pressure pipeline component type test rules.
Product specifications of 06Cr17Ni12Mo2N stainless steel seamless pipe: outer diameter 57mm~711mm, wall thickness: 2.0mm~80mm
Chemical composition of 06Cr17Ni12Mo2N stainless steel seamless pipe: carbon ≤0.08, silicon ≤1.00, manganese ≤2.00, phosphorus ≤0.035, sulfur ≤0.030, chromium 16.0~18.0, nickel 10.0~13.0, molybdenum 2.0~3.0, nitrogen: 0.10~0.16,
The high content of chromium and molybdenum gives 06Cr17Ni12Mo2N stainless steel excellent corrosion resistance, especially in an environment containing chloride ions; its corrosion resistance is significantly better than that of ordinary stainless steel. For example, in a variety of corrosive media such as seawater, salt water, acid, alkali, etc., the material can show good corrosion resistance. In addition, the addition of nickel improves the high-temperature resistance of the material, enabling it to maintain stable physical and chemical properties at high temperatures. Reasonable chemical composition design makes 06Cr17Ni12Mo2N stainless steel have high strength while maintaining good toughness, which can meet the needs of various high-strength structures.
Second, the manufacturing process of 06Cr17Ni12Mo2N stainless steel seamless steel pipe
The manufacturing process of 06Cr17Ni12Mo2N stainless steel seamless steel pipe includes raw material preparation, smelting, hot rolling, cold rolling, heat treatment, testing, and other links.
In the raw material preparation stage, high-quality 06Cr17Ni12Mo2 stainless steel plates or coils are selected as raw materials to ensure the quality of the finished product. The smelting process is carried out by an electric arc furnace or a vacuum induction furnace to accurately control the chemical composition and ensure the purity and uniformity of the material. In the hot rolling stage, the smelted billet is heated to an appropriate temperature and rolled through a hot rolling mill to form a preliminary tube billet. Subsequently, the hot-rolled tube billet is further cold-rolled to obtain precise dimensions and high surface quality. Heat treatment is an important part of the manufacturing process of 06Cr17Ni12Mo2N stainless steel seamless pipe, including solid solution treatment, aging treatment, and other processes. These processes can eliminate the stress inside the material and improve the mechanical properties and corrosion resistance of the material. Finally, the finished product is strictly tested, including chemical composition analysis, mechanical properties testing, non-destructive testing, etc., to ensure that each steel pipe meets the standards.
Third, the application field of 06Cr17Ni12Mo2N stainless steel seamless pipe
With its excellent performance, 06Cr17Ni12Mo2N stainless steel seamless pipe is widely used in many fields:
1. Petrochemical: In the petroleum refining, chemical production, and other industries, this material is widely used due to its excellent corrosion resistance. For example, pipelines and storage tanks that transport corrosive media often use 06Cr17Ni12Mo2N stainless steel seamless pipes.
2. Marine engineering: On the offshore platform, due to the need to withstand the erosion of harsh environments such as seawater and salt spray, extremely high requirements are placed on the corrosion resistance of the material. 06Cr17Ni12Mo2N stainless steel seamless pipe has become one of the preferred materials in marine engineering due to its excellent corrosion resistance.
3. New energy and environmental protection: In the fields of new energy, such as solar energy and wind energy, as well as environmental protection fields, such as wastewater treatment and exhaust gas purification, 06Cr17Ni12Mo2 stainless steel seamless pipe is also widely used due to its excellent performance. For example, when transporting high-temperature and high-pressure media (such as steam, hot water, etc.), the material can maintain stability and reliability.
Fourth, maintenance of 06Cr17Ni12Mo2N stainless steel seamless pipe
Although 06Cr17Ni12Mo2 stainless steel seamless pipe has excellent corrosion resistance, it still needs proper maintenance during use to extend its service life. Here are some maintenance suggestions:
1. Regular inspection: Check the pipeline regularly to promptly detect and deal with possible corrosion, wear, and other problems. This helps to ensure the safe operation of the pipeline and prevent safety accidents caused by aging or damage to the material.
2. Cleaning and maintenance: Clean the pipeline regularly to remove dirt and corrosion products from the surface. This helps maintain the good surface condition of the pipeline and improves its corrosion resistance. During the cleaning process, appropriate cleaning agents and tools should be used to avoid damage to the pipeline.
3. Avoid excessive stress: During installation and use, avoid applying excessive stress to the pipeline. Excessive stress may cause deformation or cracking of the material, thereby affecting its service life and safety. Therefore, during installation and use, operations should be strictly carried out in accordance with relevant specifications and requirements.
4. Reasonable storage: During storage, the pipeline should be placed in a dry and well-ventilated environment. Avoiding moisture and corrosion will help maintain its good performance and extend its service life.
