A Flat flange has a gasket floor in the equal airplane as the bolting circle face. The Applications the usage of flat flanges are regularly these in which the mating flange or flanged becoming is made from a casting. Flat flanges are in no way to be bolted to a raised face flange. ANSI B16.5 says that when connecting flat face forged iron flanges to carbon metal flanges, the raised face on the carbon metal flange ought to be eliminated and that a full face gasket is required.
Product Advantages
1. Strong corrosion resistance: stainless steel flat flanges can be used in various environments with corrosive media such as strong acids, weak acids, salts, and oxidants.
2. Good high temperature resistance: stainless steel flat flange has good high temperature resistance and can be used for a long time under high temperature conditions.
3. High hardness: The stainless steel flat flange has high strength and high hardness, is not easy to deform, and has a long service life.
4. Good functional processability: stainless steel flat flange is easy to cut, drill, weld and other thermal processing processes, and the production cost is low.
5. Environmental protection: The stainless steel material itself has environmental protection characteristics and will not pollute the environment.
Based on the above advantages, stainless steel flat flanges are widely used in chemical industry, petroleum, natural gas, water treatment, fire protection, construction and other fields, and become an important part of pipeline connection.
Product Process
The manufacturing process of stainless steel flat flange PN1.0 mainly includes the following steps: 1. Raw material preparation: Stainless steel plates, rods, pipes, etc. are selected as raw materials for production, which meet relevant standards and requirements. 2. Cutting processing: According to the required specifications and dimensions, use processing equipment such as shearing machines, bending machines, CNC lathes, etc. to cut, bend, and open holes for materials. 3. Drilling and thread processing: process flange connection holes and threaded holes to adapt to the installation and connection of pipelines. 4. Surface treatment: Polish and pickle the surface of the flange to improve the surface finish and corrosion resistance. 5. Assembly and welding: Assemble and weld the processed flange parts to form a complete flange structure. 6. Inspection and testing: inspect and test the manufactured flanges to verify whether their dimensional accuracy, material quality and connection performance meet the standards and requirements. 7. Packaging and transportation: Packaging and labeling the qualified flanges to facilitate transportation, installation and use.
