Alloy steel flanges are made of a combination of iron and other alloying elements, such as chromium, molybdenum, nickel, and vanadium. These elements are added to improve the strength, toughness, and corrosion resistance of the steel. Alloy steel flanges are typically used in applications where there is a high risk of corrosion or where the flanges need to be able to withstand high pressures or temperatures. Alloy steel flanges are available in a variety of types, including: Weld neck flanges: These flanges have a welded neck that allows them to be welded to a pipe. Slip-on flanges: These flanges slide over a pipe and are secured with bolts. Socket weld flanges: These flanges have a socket that is welded to a pipe. Lap joint flanges: These flanges have overlapping faces that are bolted together. Blind flanges: These flanges have a closed face and are used to seal off a pipe. â?¢ Alloy Steel Flange : ASTM A182 / ASME SA182 & A387 F1, F5, F9, F11, F12, F22, F91 Flanges

Common material grades include ASTM A182 F304 and F316. Face type: The face type is the shape of the flange's face. Common face types include raised face (RF), flat face (FF), and ring-type joint (RTJ). Bolting arrangement: The bolting arrangement is the number and size of the bolts that are used to connect the flanges. Here is a more detailed description of the different types of stainless steel flanges: Weld neck flange: A weld neck flange is a type of flange that has a neck that is welded to the pipe. This type of flange is typically used for high-pressure applications. Slip-on flange: A slip-on flange is a type of flange that is slipped over the pipe and then secured with bolts. This type of flange is typically used for lower-pressure applications. Socket weld flange: A socket weld flange is a type of flange that has a socket that is welded to the pipe. This type of flange is typically used for smaller pipes. Lap joint flange: A lap joint flange is a type of flange that is joined to the pipe by overlapping the flanges and then welding them together. This type of flange is typically used for low-pressure applications. Blind flange: A blind flange is a type of flange that does not have a hole in the center. This type of flange is typically used to terminate a pipe. Stainless steel flanges are a versatile and reliable component that can be used in a wide variety of applications. They are available in a variety of types, sizes, and pressure ratings to meet the specific needs of each application.

Steel flange.
We manufacture flanges in a variety of sizes and material standards. We have a large stock of carbon steel, alloy steel and stainless steel flanges. We can also manufacture your specific flange requirements within a short lead time. Changhao is a leading steel flanges exporter and manufacturer in China and we produce most of our carbon steel flanges and stainless steel flanges for export from China to the world. Steel flanges are available in a variety of shapes and sizes to suit different applications. Flanges are usually in the shape of a disc and are used to connect two pipes together or to connect pipes to pressure vessels, valves, pumps, integral flange assemblies or other components. Flanges have bolt holes around the rim. The bolts are used to connect two flanges, which are usually attached to the pipe end with a gasket in between. Flanges come in a variety of shapes, such as threaded (the pipe is screwed onto the flange), weld neck (the pipe is welded to the collar of the flange), socket weld (fillet weld connection), lap joint (connection at the short end used)), sliding, etc. The flange can also be used to cover or close the plate at the end of the pipe. This is called a blind flange. Therefore, flanges are considered to be internal components used to support mechanical parts. The ASME B16.5 and ASME B16.47 codes cover American standard pipe flanges and the EN 1092-1 code covers European steel flanges. Flanges can be manufactured and designed for specific pressure ratings; 150 lb, 300 lb, 400 lb, 600 lb, 900 lb, 1500 lb and 2500 lb.
We can manufacture flange in all carbon & steel grade in 310,904L, 316,304 in all the grades export wooden box packing
