Information

Sockolet 1'' × 3'' SW A350 LF2 Class 3000 is a Socket Weld branch outlet designed for creating branch connections in high-pressure piping systems. The branch pipe is inserted into the socket before welding, producing a strong, leak-tight connection with excellent mechanical strength.

Socket Weld fittings belong to the high-pressure forged fitting category and are widely used where reliable welded branch connections are required.

Each fitting is permanently marked with its size, pressure class, material grade, and heat number, ensuring full traceability. A 3.1 material certificate is available on request.
