Stainless Steel Flange
Definition and Usage
Stainless steel flange, as a kind of flange, is mainly made of stainless steel, which is a part of the mutual connection between shafts, usually used for the connection between pipe ends and the connection between the import and export of equipments, such as the speed reducer flange. It is widely used in construction, light and heavy industry, plumbing, electric power and other fields, especially in the need to withstand greater pressure and corrosive environment.
Classification and Characteristics
Classification
According to the connection method, stainless steel flanges can be divided into plate flat welding flanges, necked flat welding flanges, necked butt welding flanges, socket welding flanges, threaded flanges, flange covers and so on.
According to the pressure level, stainless steel flanges have a wide range of pressure levels, such as 0.6Mpa32Mpa, 150Lb2500Lb and so on.
Features
Corrosion resistance: Due to the excellent corrosion resistance of stainless steel material, stainless steel flanges are able to resist the erosion of many chemical media.
High strength: Stainless steel flanges have high strength and can withstand greater pressure.
Easy Connection: Flange connection is a convenient and fast connection, through the cooperation of bolts and gaskets, it can realize fast and firm connection.
Material and Manufacturing
The main material of stainless steel flanges is stainless steel, and the specific grades include ASTM A182 F304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti and so on. These materials have different corrosion resistance and mechanical properties, and can be selected according to the specific use environment.
In the manufacturing process, stainless steel flanges need to go through forging, casting, welding and other process steps. Forged flanges have high strength and toughness, and are suitable for high pressure, high temperature and other harsh environments; casting flanges have lower manufacturing costs and are suitable for general occasions. Welded flanges, on the other hand, connect the flanges with pipes or equipment by welding, which has greater flexibility and adaptability.

Pipeline systems: Stainless steel flanges are widely used in pipelines for various industries, including oil and gas, chemical processing, and water treatment. They allow for easy assembly and disassembly of pipe sections, making maintenance and repairs more accessible.
Pressure vessels: They are used in the construction of pressure vessels, such as boilers and tanks. They ensure a tight seal to contain high-pressure fluids or gases safely.
Petrochemical industry: In refineries and chemical plants, ss flanges are crucial for connecting pipes, valves, and equipment that handle corrosive and high-temperature materials.
Food and beverage industry: They are preferred in the food and beverage industry due to their hygienic properties. They are used in the construction of processing equipment and pipelines.
Shipbuilding: Stainless steel flanges are used extensively in shipbuilding for their resistance to saltwater corrosion. They connect various components in a ship’s piping systems.
Power generation: Power plants, including nuclear, fossil fuel, and renewable energy facilities, use ss flanges to connect pipes and valves in critical systems.
Aerospace: They are used in aircraft and aerospace applications where high strength and resistance to extreme temperatures are required.
Construction: In construction, ss flanges are used in building hvac systems, plumbing, and fire protection systems to connect pipes and ensure a secure and leak-free installation.
Wastewater treatment: Stainless steel flanges are used in wastewater treatment plants to connect pipes and components in various treatment processes.

Customizable options of Stainless Steel Flange
Our stainless steel flange is crafted from high-quality stainless steel, ensuring a long-lasting and corrosion-resistant performance in industrial applications. We offer both standard and non-standard sizes, ranging from dn 10 to dn 2000, as well as 1/2"- 48" sizes, to cater to diverse user requirements, including user input on specific size needs.
Prior to installation, ensure that flange surfaces are impeccably smooth and clean. Thoroughly remove any oil stains and rust spots.
Opt for gaskets boasting exceptional oil resistance, aging resistance, elasticity, and mechanical strength. Tailor gasket selection based on joint shape, ensuring proper installation. When welding stainless steel flanges, meticulously control welding current to prevent flange overheating, which could compromise performance.
Distribute tightening force evenly across stainless steel flanges, with gasket tightening kept within an appropriate range, typically around 1/3 of the flange pressure. Enhance flange stability by incorporating suitable stabilizing components.
The production workshop shall select appropriate raw materials for blanking according to the process requirements. Before heating, the surface of the materials must be checked. If there are visible cracks, folds, inclusions and other defects, they must be removed by peeling or other removal methods before being allowed to enter the furnace for heating.
For forging, the principle of light hitting with small deformation and heavy hitting after plasticity is improved is adopted. And forge in the form of square, polygon and square. If cracks or other defects are found on the surface during forging, they shall be timely reported to the quality inspector and technologist for reasonable removal and treatment. During upsetting, the upper and lower ends shall be chamfered or the circumference shall be blanked first, and then the blank shall be laid flat and pasted with a heavy blow. The blank shall rotate continuously around its axis to make uniform deformation. When the blank section is large, “pressing iron” can be used for flattening and upsetting.
After forging of stainless steel (1Cr18Ni9Ti) flange, in order to prevent intergranular corrosion, improve plasticity, eliminate work hardening and obtain the best corrosion resistance, heat treatment must be carried out, usually solution treatment. Heat the forging to 1050 ° C-10,709 ° C to dissolve all carbides in austenite, and then rapidly cool it to obtain single-phase austenite structure to improve its stress corrosion resistance and crystal corrosion resistance.
