Socketweld Fittings
Small Bore Socket Weld Pipe Fittings for High-Pressure Applications — Manufactured as per ASME B16.11 in Class 3000#, 6000# & 9000#
Product Overview
Socketweld Pipe Fittings
A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameter (small bore piping); generally for piping whose nominal diameter is NPS 2 or smaller.

Types
Fitting Range
Elbow 45°/90°
Socket weld elbows for changing flow direction at 45° and 90° in small bore piping.
Tee
Socket weld tee for branching flow in three directions in high-pressure systems.
Cross
Four-way socket weld cross fitting for multi-directional flow distribution.
End Caps
Socket weld end caps to seal and close pipe ends in pressure systems.
Full Coupling
Full socket weld coupling for joining two pipes of the same diameter.
Half Coupling
Half coupling for branch connections on pipes or pressure vessels.
Reducing Coupling
Socket weld reducing coupling for joining two pipes of different diameters.
Reducer Insert
Insert type reducer for pipe size reduction within a socket weld coupling.
Union
Socket weld union for easy disconnection and reconnection of pipe sections.
