Socket Weld Fittings

Internal socket designed for use in small-diameter, high-pressure pipelines, providing high strength and excellent pressure resistance.

High Quality Socket Weld Fittings We Can Supply

SSM manufactures Forged Socket Weld Fittings designed to connect small-diameter pipes within piping systems. These fittings utilize the socket welding method, in which the pipe is inserted into the fitting socket and then welded externally to establish a strong and reliable connection. Typically, these fittings are manufactured using a forging process to ensure adequate strength and pressure resistance.

Our range of Socket Weld Fittings encompasses various types:

Types : Socket 45-deg Elbow/90-deg Elbow / Socket Cross / Socket Tee / Socket Coupling/Half-Coupling/Reducing Coupling / Socket Reducing Insert / Socket Cap / Socket Union (MSS SP-83) / Sockolet (MSS SP-97)
Size: 1/8″ – 2″
Pressure: 3000, 6000, 9000
Producing Standard: ASME B16.11, MSS SP-83, MSS SP-97
Materials: ASTM A105, A182, A350, B462, or B564

Common Types We Can Manufacture

We can manufacture according to ASME B16.11, MSS SP-83, and MSS SP-97 standards, or provide customized products for you.

Socket 90-deg Elbow

This fitting allows a pipe to make a 90-degree turn, changing the flow direction sharply and is essential for creating right-angle bends in a piping system.

Socket 45-deg Elbow

A fitting that alters the pipe’s direction by 45 degrees, providing a smoother transition than a 90-degree elbow and helping to make gradual bends in the system.

Socket Cross

This fitting features four openings and is designed to connect three pipes at a central point, forming a cross-shaped junction ideal for complex piping arrangements.

Socket Tee

A fitting that alters the pipe’s direction by 45 degrees, providing a smoother transition than a 90-degree elbow and helping to make gradual bends in the system.

Socket Coupling

Used to join two sections of pipe together end-to-end, this fitting ensures a seamless continuation of the pipe line.

Socket Half-Coupling

This fitting is designed for attaching a branch pipe to the main line, usually for smaller diameter pipes, facilitating the addition of additional sections.

Socket Reducing Coupling

A versatile fitting that connects pipes of different sizes, accommodating a transition from a larger diameter to a smaller one within the pipeline.

Socket Reducing Insert

This component fits inside a socket to reduce the pipe size, allowing for adjustments in diameter within the fitting connection.

Socket Cap

This fitting is used to close off the end of a pipe, effectively sealing the pipeline and preventing leakage or entry of external elements.

Socket Union

Designed to allow for quick and easy disconnection and reconnection of pipe sections, this fitting is useful for maintenance and repairs.

Sockolet

A robust fitting that branches off from a main pipe, offering a high-pressure and temperature solution similar to a tee but designed for demanding applications.

Application of Socket Weld Fittings

SSM manufactures socket weld fittings that are widely used in various high-pressure, small-diameter piping systems. These fittings offer high strength, reliable connections, and excellent sealing performance.

Oil and gas industry: Used for high-pressure, small-diameter fluid delivery pipelines.
Chemical and pharmaceutical industries: Suitable for pipeline systems for corrosive or hazardous media.
Boiler and pressure vessel systems: Suitable for connecting high-temperature, high-pressure steam, air, and liquid pipelines.
Shipbuilding and marine engineering: Used for various high-strength, corrosion-resistant pipeline connections.

Advantages of forged socket fittings

Our socket weld fittings are popular not only because of these advantages,

High strength and pressure resistance: Socket fittings are highly mechanically strong and pressure resistant due to the forging process.
Good sealing performance: Socket welding can provide a good seal and reduce the risk of leakage.
Wide range of applications: Suitable for various industrial pipeline systems, including high-pressure and high-temperature environments.

Disadvantages of forged socket fittings

SSM reminds you that while socket weld fittings offer many advantages in specific applications, they also have some drawbacks. When selecting our fittings, please consider the following issues:

Welding stress concentration: Stress concentration is easy to occur in the welding area, which may affect the reliability of the pipeline system.
Difficult to detect: The internal weld is located inside the pipe fitting, making it difficult to detect.
It is not suitable for large-diameter pipes but only for small-diameter pipes (generally less than 2 inches).

The Materials of Socket Welding Fittings We Can Provide

SSM’s socket weld fittings are manufactured from controllable raw materials with strict quality control. We commonly supply fittings made from the following materials:

Carbon Steel Socket Welding Fittings

SSM commonly provides carbon steel socket welding fittings including ASTM A105 carbon steel forgings suitable for high-temperature and high-pressure environments, and ASTM A350 LF2 low-temperature carbon steel suitable for low-temperature applications requiring impact toughness and strength.

Stainless Steel Socket Welding Fittings

SSM commonly provides stainless steel fittings including ASTM A182 F304 and F316, which offer good corrosion resistance and strength, and are typically used for general industrial applications.

Alloy Steel Socket Welding Fittings

SSM commonly provides alloy steel socket welding fittings, such as ASTM A182 F11 and ASTM A182 F22, which excel in applications requiring high temperature, high pressure, and high strength.

Nickel Alloys Socket Welding Fittings

SSM commonly provides nickel alloy socket welding fittings such as Inconel 600, 625, 718, Hastelloy C-276, and Monel 400/K500. These nickel alloy socket welding fittings excel in applications requiring high temperature resistance, corrosion resistance, and high strength.
