What Are Socket Weld Flanges?
Socket weld flange is a flange for small diameter high pressure piping systems, which is welded by inserting the pipe into the flange socket and is suitable for scenarios that require a high degree of leak tightness.
Socket Weld flanges balance strength with ease of installation through socket welding, making them ideal for small-diameter, high-pressure systems.
Socket Weld Flange Structural Features:
- Socket design: The flange bore has a groove (socket), which is welded after the pipe end is inserted to form a firm connection.
- Single-side welding: After the pipe is inserted, fillet welding is performed on the outside of the contact surface between the flange and the pipe, no beveling is required.
- Sealing surface type: common convex surface (RF) or ring joint surface (RTJ), suitable for high pressure sealing.
- Gap reservation: After the pipe is inserted, a gap of about 1.6mm needs to be reserved with the bottom of the socket to compensate for the stress caused by thermal expansion.

Socket Weld Flanges Core Advantages:
- High-strength sealing: welding combined with socket structure, sealing is better than threaded connection, suitable for small diameter and high pressure system.
- Convenient installation: no need for complex bevel processing, welding operation is simple, suitable for space-constrained compact environment.
- Anti-vibration performance: high strength of weld seam, resistant to mechanical vibration and shock load.
- Economy: Compared with butt-welding weld neck flanges, less material is used, suitable for small pipe diameter scenarios.
Applications of Aluminum Socket Weld Flanges:
- High-pressure fluid system: steam, gas, hydraulic oil and other high-pressure small-diameter pipeline (such as instrumentation lines, sampling lines).
- Chemical and petrochemical industry: corrosive media small diameter connection (need to match the corrosion-resistant materials such as stainless steel).
- Power industry: boiler water piping, high pressure steam instrumentation lines.
- Valve and pump connection: need frequent maintenance or compact installation of the interface position.
