Neck Butt Weld Titanium Flange, also known as Long Neck Butt Weld Flange or Long Neck Flange, is a Titanium Fitting used for piping connections. It is usually used where higher pressure and temperature ratings are required, as it has a longer neck to better distribute stress and improve the strength and sealing of the connection.
This Titanium Flange is characterized by:
1. structure: it has a neck (neck) that extends from the face of the flange, and this neck can increase the contact area of the flange welded to the pipe, thus improving the welding strength.
2. Application: It is widely used in high-pressure piping systems in petrochemical, electric power, shipbuilding and other industries.
3. Material: you can choose different materials according to the different use environment, common carbon steel, stainless steel, alloy steel and so on.
4. Standard: The design and production will follow the relevant international or national standards, such as ASME, DIN, etc.
Butt-welding flanges with neck are fixed on the pipeline by welding, and then bolted to other flanges to form a complete pipeline system. This type of flange is very common in applications that require high safety and reliability due to its excellent performance.
The sealing surface forms of necked butt weld flanges are:
Raised Face (RF), Concave Face (FM), Convex Face (M), Tongue and Groove (T), Groove Face (G), and Full Flat Face (FF).
Advantages:
Connection is not easy to deform, sealing effect is good, wide range of applications, suitable for temperature or pressure fluctuations in the pipeline or high temperature, high pressure and low temperature pipeline, but also used to transport expensive media, flammable and explosive media, toxic gases on the pipeline
Disadvantages:
Butt-welding flanges with necks are bulky, heavy, expensive and difficult to install and position. Therefore, it is easier to be bumped during transportation.
