Stainless Steel Flange

As the professional manufacturer, SN Valve would like to provide you high quality stainless steel flange. Stainless steel flanges are a reinforced structure used to enhance the robustness of the design. They are widely used in water conservancy, electricity, power stations, pipe fittings, industry, pressure vessels and other fields.

Material and Characteristics

Material: Stainless steel flange is mainly made of stainless steel, stainless steel is stainless steel, corrosion resistance as the main characteristics, and the chromium content of at least 10.5%, the maximum carbon content of not more than 1.2% of the steel. Common stainless steel grades are 304, 304L, 316, 316L, etc. These grades of stainless steel have different corrosion resistance, heat resistance and mechanical properties, you can choose the right material according to the specific use environment.

Characteristics:

●Corrosion resistance: stainless steel flanges have excellent corrosion resistance and can maintain stable performance in a variety of corrosive media.

●High strength: stainless steel flanges have high strength and stiffness, capable of withstanding large pressures and loads.

●High temperature resistance: some grades of stainless steel flanges (such as 316L) have good high temperature resistance and are suitable for use in high temperature environments.


Types and Connections

●Types: Stainless steel flanges can be divided into various types according to different structures and uses, such as necked flat welding flanges, butt welding flanges, threaded flanges, sliding flanges, lap flanges and socket welding flanges.

●Connection: The connection of stainless steel flanges mainly includes flange nut and bolt connection. The two flanges are tightly connected together by bolts and nuts to form a reliable sealing structure.


Application Scenario and Precautions

1.Application Scenario: Stainless steel flanges are widely used in various piping systems and equipment connections, such as chemical, petroleum, natural gas, pharmaceutical, food and other industries. In these industries, the corrosion resistance and high strength characteristics of stainless steel flanges are fully utilized.

2.Precautions:

●When choosing stainless steel flanges, it is necessary to choose the appropriate material and model according to the specific use environment.

●During installation, it is necessary to ensure that the sealing surface of the flange is clean and flat, and the sealing gasket is correctly installed to ensure the sealing performance.

●Regular inspection and maintenance of stainless steel flanges, timely detection and treatment of potential problems.

Blind Flange

Blind Flange

A blind flange is a type of flange without a hole in the center, which is designed to seal off the end of a pipeline or used to remove debris from a pipeline during maintenance. It is usually made of high quality steel, such as carbon steel, alloy steel or stainless steel, to meet the needs of different working environments.

Welding Neck Flange

Welding Neck Flange

Chinese manufacturer SN Valve offers high-quality Welding Neck Flange. A butt-weld flange is a flange with a longer neck that usually matches the outer diameter of the pipe so that it can be welded to the pipe. This flange structural design improves the rigidity and strength of the flange, while improving the sealing performance of the connection. Butt-weld flanges are usually made of high-quality forged steel materials and can withstand high-pressure and high-temperature working environments.

Slip-On Flange

Slip-On Flange

As a professional manufacturer, SN Valve is willing to provide you with the best slip-on flanges. Slip-on flanges are a special type of flange made of a circular metal plate with one or more bolt holes on it. This type of flange is designed to easily slide and fix pipes or fittings together, allowing two or more parts to be connected. They are relatively simple in construction, usually matching the outer surface of the pipe, and can be welded directly to the pipe or secured to it by fasteners.

Plate (PL) Flanges

Plate (PL) Flanges

Find a huge selection of Plate (PL) Flanges from China at SN Valve. Plate flat welding flange is a kind of flange cut from steel plate with a full flat flange face and a round bore in the center for connection with pipes or other flanges. The connection is usually made by flat welding, i.e., the flange is aligned with the protruding part of the pipe or equipment and then firmly connected by welding.

Threaded Flange

Threaded Flange

Threaded flanges are flanges with internal or external threads that are connected by screwing the threads on the flange to the threads on the pipe or equipment against each other. This type of flange is usually used in low-pressure and low-temperature operating environments because of its relatively low connection strength, but easy installation and removal.

Socket Welded Flange

Socket Welded Flange

As the professional manufacturer, SN Valve would like to provide you high quality socket welded flange. Socket weld flange is a flange in which the end of the pipe is inserted into the step of the flange ring and welded at the end and outside of the pipe. It usually consists of flange body, bolt holes, sealing surface and other parts, and its structural form has two kinds of necked and non-necked. Necked socket weld flanges have good rigidity, small welding deformation and better sealing, so they are more common in practical applications.
