Pipe Outlet Fittings

Pipe Outlet Fittings

Description

Pipe outlet fittings are branch connection components used to create reinforced outlets from a main pipe without the need for a full tee fitting. These fittings are widely used in high-pressure and high-temperature piping systems where structural integrity and flow efficiency are critical.

Outlet fittings such as weldolet, sockolet and threadolet are typically manufactured in accordance with MSS SP-97 and ASME piping standards. In engineered piping systems, outlet fittings are often used together with stainless steel pipe fittings and forged steel flanges to form complete branch connection assemblies for industrial piping systems.

These fittings are commonly used in petrochemical plants, offshore platforms, refineries, LNG facilities, power plants and nuclear projects where branch connections must meet strict mechanical strength and inspection requirements.

Specifications / Standards

Pipe outlet fittings are manufactured in accordance with international piping and forging standards to ensure dimensional accuracy, pressure rating compliance and material traceability.

Typical manufacturing and inspection standards include:

MSS SP-97 – Integrally Reinforced Branch Outlet Fittings
ASME B16.11 – Forged Fittings
