ASME B16.11 / MSS SP-97 Welding Outlets | Stainless Steel Welding Outlets | Carbon Steel & Alloy Steel Branch Connections | Industrial Piping Fittings
Elite manufactures and supplies high-quality Welding Outlets for industrial piping systems, providing reliable branch connections for oil and gas, petrochemical, chemical processing, power generation and general engineering applications. Welding Outlets are branch connection fittings used to create a 90° branch from a main pipe where a standard tee may not be suitable. Designed for welded installation, these fittings provide a reinforced branch connection while maintaining piping system integrity.
Elite offers Welding Outlets in stainless steel, carbon steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other project-specified materials. Available configurations include standard and specialty branch outlets designed according to applicable dimensional standards, material specifications and customer requirements.
