Butt Weld Pipe Fittings
A stainless steel flange is a type of pipe fitting used to connect two pipes or to connect a pipe to a valve, pump, or other equipment. It is typically made from stainless steel, which provides corrosion resistance and durability.Stainless steel flanges come in various types, including:Weld neck flange: This type of flange has a tapered neck and is welded to the pipe. It provides excellent strength and is commonly used in high-pressure and high-temperature applications.Slip-on flange: This flange is slipped onto the pipe and then welded in place, as it has a flat face and a bore slightly larger than the outer diameter of the pipe.Blind flange: Used to close off the end of a pipe, a blind flange is solid and has no opening. It is commonly used to block off sections or ends of piping systems.Threaded flange: This flange has internal threading that matches the external threading on the pipe. It is easier to install and is commonly used in low-pressure applications.Lap joint flange: This flange does not have a raised face or hub and is designed to slide over the pipe. It is commonly used in systems that require frequent dismantling.Stainless steel flanges are used in a variety of industries, including petrochemical, oil and gas, food and beverage, pharmaceutical, and water treatment, among others. They are chosen for their resistance to corrosion, high temperatures, and strength.When selecting a stainless steel flange, factors like size, pressure rating, temperature range, and type of connection (welded, threaded, etc.) need to be considered to ensure the flange is suitable for the specific application. It is advisable to consult with a professional or refer to industry standards and specifications for the proper selection and installation of stainless steel flanges.
