Product Description

Structural Features
Socket Welding Connection: There is a socket hole at one end of the flange, and the pipeline is inserted into this hole for welding connection. This connection method makes the connection between the pipeline and the flange tighter, and it can withstand higher pressure and tensile force.
Necked Structure: It usually has a neck. The presence of the neck increases the strength and stability of the flange. At the same time, it also helps to reduce the concentration of welding stress and improve the reliability of the connection.
Specification Parameters
Nominal Diameter: The range is usually from DN15 to DN200 or even larger, covering the connection requirements of various pipeline sizes. For example, a socket welding flange with a nominal diameter of DN15 is suitable for pipelines with an outer diameter of about 21.3mm, while a flange with a nominal diameter of DN200 corresponds to a pipeline with an outer diameter of 219.1mm.
Nominal Pressure: Common ones include different grades such as PN2.0MPa, PN5.0MPa, and PN10.0MPa. A higher nominal pressure indicates that the flange can withstand greater internal pressure and is suitable for high-pressure pipeline systems. For example, in some petrochemical plants, socket welding flanges with a nominal pressure of PN10.0MPa and above may be used.
Outer Diameter of the Flange, Diameter of the Bolt Hole Center Circle, Quantity and Diameter of Bolt Holes: These dimensions vary according to different nominal diameters and nominal pressures. Taking a socket welding flange with a nominal diameter of DN15 and a nominal pressure of PN2.0MPa as an example, its outer diameter of the flange may be 90mm, the diameter of the bolt hole center circle is 60.5mm, and there are 4 bolt holes with a diameter of 16mm.
Material Selection
Carbon Steel: Such as A105 steel, it has good strength and toughness, and the price is relatively low. It is suitable for general industrial pipeline systems, such as water supply and drainage, heating, ventilation, and air conditioning and other fields.
Stainless Steel: Common materials include 304, 316, etc. 304 stainless steel has good corrosion resistance and oxidation resistance, and is suitable for some occasions with high requirements for corrosion resistance, such as the food processing, pharmaceutical and other industries; 316 stainless steel further improves the corrosion resistance on the basis of 304, especially has better resistance to some media containing chloride ions, and is often used in marine engineering, chemical industry and other fields.
Alloy Steel: It has higher strength and special properties, such as high-temperature resistance, low-temperature resistance, etc., and is suitable for pipeline systems under some special working conditions, such as high-temperature and high-pressure steam pipelines, low-temperature cryogenic pipelines, etc.
Sealing Surface Forms
Raised Face (RF): It is the most common form of sealing surface, with simple processing and wide application. It is suitable for general media and pressure conditions and can meet the sealing requirements of most industrial pipelines.
Male and Female Face (MFM): It is composed of a male face and a female face, with good sealing performance, and can effectively prevent the leakage of media. It is often used in occasions with high requirements for sealing, such as pipeline systems for toxic, flammable and explosive media.
Tongue and Groove Face (TG): The tongue and groove of the sealing surface cooperate with each other, and the sealing effect is better. Moreover, it has a good positioning effect on the gasket, which can ensure that the gasket will not be displaced during installation and use. It is suitable for pipeline connections with high pressure and high sealing requirements.
Ring Joint Face (RJ): An octagonal or oval metal ring is used as the sealing element, and the sealing performance is very good. It is suitable for pipeline systems for high-temperature, high-pressure, and highly corrosive media, such as the key parts of the refining, chemical industry and other industries.
Application Fields
Petrochemical Industry: In the processes of petroleum refining, chemical production, etc., it is necessary to transport various flammable, explosive, toxic and harmful media. Socket welding flanges are widely used in various pipeline systems with their reliable connection and sealing performance to ensure the safe and stable operation of the production process.
Power Industry: Whether it is thermal power generation, hydropower generation or nuclear power generation, it is inseparable from a large number of pipeline systems to transport media such as steam, water, and oil. Socket welding flanges play an important role in connecting and sealing these pipeline systems, ensuring the normal operation of power production.
Pharmaceutical and Food & Beverage Industries: These two industries have high requirements for hygiene. Socket welding flanges made of stainless steel are widely used in pipeline systems due to their good corrosion resistance and hygienic performance to prevent the media from being contaminated and ensure product quality and safety.
Installation and Maintenance
Installation: During installation, first ensure that the socket parts of the pipeline and the flange are clean and free of impurities. Then insert the pipeline accurately into the socket hole of the flange and carry out the welding operation. During the welding process, it is necessary to strictly follow the requirements of the welding process, control the welding parameters, and ensure the welding quality. After the welding is completed, it is necessary to conduct non-destructive testing on the weld, such as radiographic testing, ultrasonic testing, etc., to check whether there are defects in the weld.
Maintenance: Regularly check the connection parts of the flange to see if the bolts are loose and whether there is any leakage on the sealing surface. For flanges in a corrosive environment, pay attention to checking their corrosion conditions and take anti-corrosion measures in a timely manner, such as painting, galvanizing, etc. If problems such as damage or leakage of the flange are found, repairs or replacements should be carried out in a timely manner.

Socket welding flange is an important type in flange connection.
