Nipple Welding Outlet
Product Details
Nipple Welding Outlet
We manufacture a wide range of high-strength, corrosion-resistant welding outlets (olet fittings) in materials such as Stainless Steel, Carbon Steel, and various alloys to ensure reliable, integral branch connections even in high-pressure and high-temperature environments.
Description
A Nipple Welding Outlet, commonly known as a Nipolet, is a unique one-piece forged branch fitting that combines an outlet with a built-in, pre-attached pipe nipple. This integrated design is highly efficient as it eliminates one full weld during installation, saving time and labor. It provides a high-strength, 90° integrally reinforced connection from a run pipe, extending out to a socket weld or threaded end. Manufactured from carbon steel, stainless steel, and alloy steels, Nipolets are ideal for high-pressure and high-temperature applications, especially for vents, drains, and instrument connections in oil & gas, petrochemical, and power plants.
