Stainless Steel Socket Weld Flanges

Stainless Steel Socket Weld Flanges

Stainless steel socket weld flanges are specialized components used in piping systems to provide safe and leak-proof connections. There is a socket-like groove on the inside that allows pipe to be inserted and welded for a strong and reliable connection. This welding method provides a long-lasting connection that is resistant to leakage and vibration. Commonly used in high pressure and high temperature applications such as chemical, oil and gas, pharmaceutical, food and beverage, and water treatment industries.

What‘s The Feature Of Socket Weld Flange?

Stainless Steel Socket Weld Flanges have a socket or recess that fits over the pipe end, allowing for a fillet weld on both the inner and outer sides of the flange. This socket weld connection provides a strong and leak-free joint between the flange and the pipe.

Socket Weld Flanges have a compact design compared to other flange types. The absence of an external weld neck reduces the overall size and weight of the flange, making it suitable for space-constrained applications.

Socket Weld Flanges are designed to withstand high-pressure and high-temperature applications. The socket weld joint provides added strength and integrity, making them suitable for demanding operating conditions.

Stainless Steel Socket Weld Flanges are made from corrosion-resistant stainless steel materials, such as 304 or 316 grades. This ensures durability and protection against corrosion, making them well-suited for use in corrosive environments.

Socket Weld Flanges can have either a raised face or a flat face on the flange’s sealing surface. The choice of face type depends on the specific application and the requirements for sealing and gasket compatibility.

Socket Weld Flanges are versatile and can be used in various industries and applications. They are commonly used in oil and gas, chemical processing, petrochemical, power generation, and other high-pressure piping systems.

Socket Weld Flanges are relatively easy to install and align. The socket weld joint allows for a secure connection, and the absence of external weld necks simplifies alignment during installation.

It’s important to note that Socket Weld Flanges have some limitations. They are not suitable for applications with cyclic loading, as the welds may be prone to fatigue. Additionally, disassembly and repair of socket weld joints can be more challenging compared to flange types that allow for easier removal and replacement.
