Nipolets
Nipolets are one-piece branch connection fittings with an extended pipe body, designed for valve take-offs, drains, and vents, featuring male socket-weld or male threaded outlets.
Ideal for high-pressure and high-temperature piping systems, Nipolets are widely used in oil and gas, petrochemical, and power generation industries for efficient branch connections.
Nipolets combine the functionality of a Weldolet with an integrated nipple, offering a self-reinforced branch connection with an extended body for specialized applications like valve take-offs, drains, and vents. Available with male socket-weld or male threaded outlets, they provide versatility in connecting branch pipes without additional fittings. Typically ranging from 3.5 to 6.5 inches in length, Nipolets are manufactured for Extra Strong (XS) and Double Extra Strong (XXS) schedules, ensuring durability in demanding conditions. Their design simplifies installation and enhances system integrity in high-pressure environments.
