Nipple Outlets (Nipolets)
Nipple Outlets | MSS SP-97 Branch Connection Fittings | Carbon Steel, Stainless Steel, Duplex & Nickel Alloy Nipolets
Elite manufactures and supplies Nipple Outlets, also known as Nipolets, for industrial piping systems requiring a branch connection from a main pipe. These fittings feature an extended outlet body with a plain, beveled, or threaded end, depending on the specified configuration. They are used to connect smaller-bore piping, drains, vents and instrument connections to larger piping systems and equipment.
Elite offers Nipple Outlets in carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other project-specified materials. Available configurations include butt-weld, socket-weld and threaded connections, subject to the applicable product design and customer requirements.
Our Nipple Outlets are suitable for selected applications in oil and gas, chemical processing, power generation, petrochemical plants and industrial facilities. Material grades, outlet dimensions, pressure requirements and connection types can be specified according to the operating conditions and project requirements.
