One of the key benefits of using stainless steel flanges is their resistance to corrosion. They can withstand harsh environments, high temperatures, and exposure to corrosive chemicals and fluids. This makes them ideal for use in industries such as oil and gas, chemical processing, food and beverage, and pharmaceuticals, where corrosion resistance is critical. Stainless steel flanges also offer high strength and reliability. They can withstand high pressure and temperature without warping, cracking, or leaking. They are designed to provide a tight and secure connection between different components, ensuring the safety and efficiency of the system. There are several types of stainless steel flanges, including weld neck flanges, slip-on flanges, threaded flanges, blind flanges, and lap joint flanges.
Stainless steel flanges typically range in size from ½ inch to 48 inches in diameter, although larger sizes are also available for specialized applications. The thickness of the flange also varies depending on the size and pressure rating of the flange. In addition to standard sizes, custom-made flanges can also be manufactured to meet specific requirements. This includes flanges with non-standard dimensions, flanges with a specific facing type, and flanges made from exotic materials.
Flange Size (Nominal Diameter) | Outside Diameter (OD) | Bolt Circle Diameter (BCD) | Number of Bolt Holes | Bolt Hole Diameter | Thickness | Pressure Rating |
---|---|---|---|---|---|---|
½ inch | 3.50 inches | 2.38 inches | 4 | 0.62 inches | 0.44 inches | 150 lbs |
1 inch | 4.25 inches | 2.75 inches | 4 | 0.62 inches | 0.50 inches | 150 lbs |
2 inch | 6.00 inches | 4.75 inches | 4 | 0.75 inches | 0.63 inches | 150 lbs |
4 inch | 9.00 inches | 7.50 inches | 8 | 0.75 inches | 0.94 inches | 150 lbs |
6 inch | 11.00 inches | 9.50 inches | 8 | 0.75 inches | 1.12 inches | 150 lbs |
8 inch | 13.50 inches | 11.75 inches | 8 | 0.75 inches | 1.25 inches | 150 lbs |
10 inch | 16.00 inches | 14.25 inches | 12 | 0.88 inches | 1.38 inches | 150 lbs |
These are magnetic and have lower corrosion resistance than austenitic stainless steels. They are often used in automotive and architectural applications due to their good formability and high-temperature oxidation resistance. Examples include 430 and 446 stainless steels. These are magnetic and have high strength and hardness. They are often used in cutlery, aerospace, and medical equipment applications. Examples include 410 and 420 stainless steels. These are a combination of austenitic and ferritic stainless steels, offering high strength and excellent corrosion resistance. They are often used in chemical processing, oil and gas, and marine applications. Examples include 2205 and 2507 stainless steels.
Stainless steel flanges are used to connect pipes, valves, and other equipment in chemical and petrochemical processing plants. They offer excellent resistance to corrosion and high temperatures, making them ideal for use in harsh environments. Stainless steel flanges are used in oil and gas production, transportation, and processing. They provide a secure connection between pipes and equipment, and their corrosion resistance ensures that they can withstand exposure to harsh chemicals and environments. Stainless steel flanges are commonly used in the food and beverage industry, where hygiene and cleanliness are essential.
