Forged Outlet Fittings (Olet Fittings) – Weldolet, Sockolet, Threadolet & More | High-Pressure Branch Connections


Release Time:

Jul 31,2025

Forged Outlet Fittings (Olet Fittings) are high-performance branch connectors used to join smaller pipes to larger header pipes. Available in various types like Weldolet, Sockolet, Threadolet, Latrolet, Elbolet, Nipolet, and others, they provide a reinforced, leak-proof connection and reduce stress at junctions. Manufactured in compliance with ASME B16.11 and MSS SP-97, these fittings support pressure classes 3000, 6000, 9000, and are available in carbon steel, stainless steel, alloy steel, and exotic materials such as Inconel, Monel, Duplex. Applications: Widely used in oil & gas, petrochemical, pressure vessels, power plants, and marine platforms, forged outlet fittings are cost-effective alternatives to standard tees, ideal for high-pressure and high-temperature piping systems.

FORGED FITTINGS – OUTLET (OLET FITTINGS)

Structural Features:

Outlet fittings, commonly known as Olets, are forged branch fittings used to create a branch connection from a larger (header) pipe to a smaller (branch) pipe.

They are designed to provide a smooth, reinforced, and strong transition, reducing stress concentration at the junction.

Olets are widely used as alternatives to standard tees, especially when welding to the run pipe is more practical or cost-effective.

Common Types of Outlet Fittings:

Weldolet – for butt weld connections

Sockolet – for socket weld connections

Threadolet – for threaded connections

Latrolet – for angled branches

Elbolet – for elbows

Nipolet / Sweepolet / Flangolet – for special applications

Each type is chosen based on the connection method and pipe configuration.

 

Standards:

ASME B16.11 (partial)

MSS SP-97 – Standard for Integrally Reinforced Forged Branch Outlet Fittings

Custom dimensions also available based on project needs

 

Pressure Ratings:

Generally designed to match the pressure class of the run pipe

Available in Class 3000 / 6000 / 9000 and customized ratings

 

Applications:

Outlet fittings are widely used in:

Oil and gas pipelines

Petrochemical processing

Pressure vessels

Power generation systems

Shipbuilding and offshore platforms

General industrial piping networks

They provide a cost-effective and structurally sound way to add branches without full tees or reinforcement pads.

 

Common Materials:

Carbon Steel (ASTM A105)

 

Stainless Steel (ASTM A182 F304, F316)

 

Alloy Steel (ASTM A182 F11, F22)

 

Also available in Duplex, Monel, Inconel, and other exotic alloys

 

Recommendation:

Outlet fittings are ideal for applications where customized branch connections are needed in high-pressure or high-temperature environments.

They help ensure safe, durable, and efficient distribution of flow in complex piping systems.
