Inconel 625 flanges are a commonly used connecting component in high temperature and high pressure environments with excellent corrosion resistance and high strength properties. The following is the general production process of Inconel 625 flanges:
1. Raw material preparation: the raw materials for producing Inconel 625 flanges are mainly nickel-based Inconel 625 and some other alloying elements. These raw materials need to be prepared according to specific ratios and undergo strict chemical analyses and testing to ensure that they meet the requirements of product standards.
2. Material melting: after weighing, the raw materials are put into vacuum induction melting furnace or electric arc furnace for melting. Under high temperature, the raw materials are gradually melted and mixed evenly to form the molten metal of Inconel 625.
3. Forging or Extrusion: The molten metal is cast or continuously cast to transform it into billets of Inconel 625. Billets are generally forged or extruded with large-scale forging and pressing equipment to form forgings or extrusion billets with predetermined shapes and sizes through continuous deformation and plasticity changes.
4. Heat treatment: The forging or extrusion billet is heat-treated to remove internal stresses and improve structure and properties. The heat treatment process consists of heating to a specific temperature and holding it for a certain period of time, followed by gradual cooling. 5.
5. Machining: Heat treated forgings or extrusions are machined to obtain the final flange shape. This includes machining processes such as turning, milling, drilling, grinding, etc. to ensure that the flanges meet the required dimensional and surface accuracy.
6. Inspection and quality control: During the production process, various inspections and tests are carried out on the Inconel 625 flanges to ensure that their quality and performance meet the standard requirements. Common tests include dimensional measurement, hardness test, non-destructive testing, chemical composition analysis and so on.
7. Surface treatment: The flanges are subjected to surface treatment after completion of processing, and common methods include polishing, sandblasting, acid washing, etc., in order to improve the surface quality and appearance of the flanges.
8. Packaging and Delivery: After testing and surface treatment, Inconel 625 flanges are finally packaged, usually in wooden or cardboard boxes, and labelled with relevant information and signs. Then it will be delivered to customers according to the order requirements
9. Customer requirements confirmation: before delivery, the manufacturer makes final confirmation with the customer to ensure that the Inconel 625 flanges produced meet the customer’s requirements and specifications. This includes confirming the size, material, pressure level, connection method and so on.
10. Transport and logistics arrangement: after completing the packaging, Inconel 625 flanges are ready for transport. According to the customer’s requirements and order agreement, choose the appropriate mode of transport, such as land, sea or air transport, and arrange the transport details in co-operation with the logistics company to ensure that the products are safely delivered to the destination.
11. Installation and application: once the Inconel 625 flanges are delivered to the customer, the customer can install the flanges directly on the corresponding equipment or pipelines as needed. According to the specific application requirements, correct installation and connection will be carried out to ensure that the flanges can operate properly and meet the working conditions.
To sum up, the production process of Inconel 625 flanges includes steps such as raw material preparation, material melting, forging or extrusion, heat treatment, processing and moulding, testing and quality control, surface treatment, packaging and delivery. These steps ensure the quality, performance and reliability of the final product to meet customer needs and industry standards.
