Customized pure nickel 200 seamless pipe ni 200 nickel tube

Nickel 200 (UNS N02200) Nickel 201 (UNS N02201)

Ni200 and Ni201 are two common pure nickel materials that have similar chemical compositions but are slightly different.

Ni200 is a commercial purity nickel material containing approximately 99.2% nickel, with the remainder being impurity elements. It has excellent corrosion resistance and high temperature performance and can operate stably in various corrosive media. Ni200 has good mechanical properties and can be processed and formed by cold working and hot working. It is widely used in chemical industry, petroleum, electric power, aerospace and other fields to manufacture chemical equipment, petroleum refining equipment, nuclear industry equipment, power generation equipment and aerospace components.

Ni201 is a high-purity nickel material with a nickel content of approximately 99.5%. It is a higher-purity version of Ni200. Compared with Ni200, Ni201 has a lower carbon content, so in some special application scenarios, such as the nuclear industry and high temperature and high vacuum environments, Ni201 is more suitable. Ni201 has similar corrosion resistance and high temperature performance to Ni200, and can also be formed and processed through cold working and hot working. It is commonly used in the manufacture of nuclear reactor components, chemical processing equipment, electronic equipment, and high-temperature heat exchangers.

Production Process:

The production process of pure nickel tubes can be summarized as the following main steps:

Material preparation: First, high-purity nickel raw materials need to be prepared. These raw materials can be nickel powder, nickel blocks or other forms of nickel alloys. Ensuring the purity and quality of raw materials is crucial to obtaining high-quality pure nickel pipes.

Smelting and casting: Nickel raw materials are put into high-temperature furnaces for melting. Once the nickel is completely melted, it can be cast using a variety of methods, such as continuous casting, static casting, centrifugal casting, etc. By casting, a primary blank of the desired shape and size can be obtained.

Heat treatment: Heat treatment is performed on the primary blank to eliminate internal stress and improve the grain structure. The temperature and time of heat treatment are controlled according to specific requirements to obtain the required mechanical properties and organizational structure.

Hot and cold rolling: Heat-treated blanks usually require further processing through hot and cold rolling processes. Hot rolling refers to heating the blank to a high temperature and then continuously rolling it through a rolling mill to reduce the cross-sectional size and improve uniformity. Cold rolling refers to further rolling and dimensional adjustment through rolling mills at room temperature.

Cold drawing: By cold-drawing the cold-rolled blank, the diameter and wall thickness are gradually reduced through multiple drawing processes, while the mechanical properties and surface quality of the pipe are improved.

Finishing and annealing: After cold drawing, pure nickel pipes need to be finished, that is, they are cut to length through processes such as cutting, cutting, and trimming, and necessary annealing is performed to restore the plasticity of the material and improve its physical properties.

Surface treatment: Finally, pure nickel pipes can be surface treated, such as pickling, polishing, plating, etc., to improve their surface quality, corrosion resistance and aesthetics.

Inspection and quality control: Strict inspection and quality control are required at all stages throughout the production process to ensure that pure nickel pipes meet the prescribed technical standards and customer requirements.

Precautions:

Safety measures: When producing and processing pure nickel pipes, relevant safety operating procedures and operating specifications should be followed, including wearing personal protective equipment (such as gloves, goggles, protective clothing, etc.) to ensure a safe working environment.

Material quality control: Ensure the use of high-quality nickel raw materials, and conduct necessary material testing and quality control to ensure that the pure nickel tubes produced meet the required technical requirements and standards.

Processing temperature control: Pure nickel pipes are sensitive to temperature during processing. The processing temperature range should be controlled to avoid material deterioration caused by too high temperatures or processing performance affected by too low temperatures.

Surface treatment: For some special applications, pure nickel pipe may require surface treatment, such as pickling, polishing or plating. When performing surface treatment, attention should be paid to selecting appropriate treatment methods and chemical reagents, and following correct operating procedures to ensure safety and quality.

Corrosion and corrosion protection: Pure nickel pipes generally have good corrosion resistance, but may still be subject to corrosion in special environments. When selecting pure nickel pipe for use in a specific environment, it is necessary to fully understand the environmental conditions and corrosion characteristics, and take appropriate corrosion protection measures, such as surface coating, anti-corrosion treatment, etc.
