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.

Pressure Vessel Flange

Pressure Vessel Flange

Pressure vessel flange, i.e. pressure vessel flange, is a key component on the pressure vessel used to connect piping, valves, instruments and other equipment.Pressure vessel flange is a standardized connecting part, which is connected to the inlet and outlet of the pressure vessel or other parts that need to be connected to achieve a reliable connection between the pressure vessel and other equipment or pipelines. In the pressure vessel, the flange not only plays the role of connection, but also bears the important task of ensuring the sealing performance and bearing pressure.

Non Standard Flange

Non Standard Flange

Non standard flanges are relative to standard flanges, which refer to those flanges that do not conform to the standard sizes, shapes or materials stipulated by the state or industry.
Non-standard: the size, shape or material of non-standard flanges usually do not conform to common national or industry standards.
Customization: due to the special nature of non-standard flanges, it usually needs to be customized and produced according to the specific needs of customers.

Long Weld Neck Flange

Long Weld Neck Flange

Long Weld Neck Flange (LWN) is an extended form of butt welded flange with a neck, whose neck height is significantly higher than that of ordinary butt welded flanges. The neck is usually designed in a straight cylindrical shape, and the height is adjusted according to the nominal diameter (DN): when DN ≤ 100, the neck height is 229mm, and when DN>100, it is 305mm. The thickness of the neck wall gradually transitions to the thickness of the pipe wall, effectively improving the stress distribution, enhancing the rigidity and bearing capacity of the flange, making it suitable for working conditions with high pressure, high temperature and frequent temperature changes.

Flat Face Flange

Flat Face Flange

Flat Face Flange is a type of flange in which the sealing surface and the overall end face of the flange are in the same plane. Its design feature is that the sealing contact surface is flat, without protrusions or depressions, suitable for sealing scenarios that require large areas of uniform contact.
