Products Description
In engineering, when standard flanges cannot be matched with pipe fittings and pipelines, reducing flanges are used instead.
There are two major categories of flange standards in China: national standards (GB) and chemical industry standards (HG). The latest chemical industry flange standards HG/T20592-20635-2009 also adopt the European pipe flange standard represented by the European Union EN (nominal pressure expressed in PN) and the American pipe flange system represented by the American ASME (nominal pressure expressed in Class), and their characteristic dimensions also differ between the nominal dimensions of the same level; Furthermore, the diameter series of pipelines in China are also divided into metric series and English series, which also have differences in nominal sizes at the same level; In addition, when there are special process requirements, such as instrument joints and flanges with glass lining, there are also some special requirements for their characteristics (a separate standard HG/T2140-2009 has been established for them). Therefore, there has been an inevitable situation of mixing in engineering, and reducing the inner diameter size of the flange is the simplest and most effective solution, resulting in non-standard reducing flanges.

The main applications of Reducing nickel flange
Connection: Flanges can connect equipment such as pipelines, valves, pumps, and containers. By fixing flanges with screws or nuts, different equipment, pipelines, or components can be tightly connected together.
Sealing: The flange adopts the principle of surface sealing, which can effectively ensure that the connection will not leak air, water, or oil. Good sealing effect can ensure safe and stable operation during the production process.
Support: Flanges can serve as supporting components for pipelines or equipment, improving their stability and reducing vibration and deformation caused by stress.
Easy disassembly: The flange disassembly is simple and convenient, suitable for equipment and pipelines that require frequent cleaning, maintenance, or replacement, and also convenient for maintenance personnel.
Products advantages
Reliability: The flange adopts the principle of surface sealing, with strong connection tightness, which can ensure the safe and reliable operation of the fluid conveying system. And it can still operate stably under high temperature or high pressure working conditions.
Economy: The manufacturing cost of flanges is relatively low, and assembly through fixing methods such as screws or nuts is simple, which can improve production efficiency and reduce production costs.
Easy installation: The flange is designed considering factors such as disassembly, cleaning, maintenance, and replacement, which has good operability and can reduce labor, material, and time costs.
Universality: The flange adopts standardized design, meeting the standards and specifications of multiple countries and regions, and can be used in conjunction with various brands of equipment and pipelines.
Wide connection range: The flange has a wide range of applications and can connect various materials, specifications, and types of equipment and pipelines, such as steel, chemical, petroleum, natural gas, power, and water conservancy.
Diversified selection: There are many types and specifications of flanges, and suitable flange types and specifications can be selected according to different needs, which can meet various production processes and customer needs.
Production Process
Centrifugal flanges belong to the precision casting method for producing flanges. This type of casting has a much finer structure and improved quality compared to ordinary sand casting, and is less prone to problems such as loose structure, air holes, and sand holes.
centrifugal casting:
① Place the selected raw material steel into an intermediate frequency electric furnace for melting, so that the temperature of the molten steel reaches 1600-1700 ℃;
② Preheat the metal mold to 800-900 ℃ and maintain a constant temperature;
③ Start the centrifuge and inject the molten steel in step ① into the preheated metal mold in step ②;
④ The casting should be naturally cooled to 800-900 ℃ for 1-10 minutes;
⑤ Cool with water to near room temperature, demould and remove the casting.
