ASME B16.11 | Forged Threaded / Screwed 45° Elbows | Class 2000–6000 | NPS 1/8–4
Elite provides high-quality Forged Threaded / Screwed 45° Elbows for industrial piping, process systems, oil & gas, petrochemical, chemical, power generation and general engineering applications. Manufactured using controlled forging and precision machining processes, these fittings are designed to provide reliable dimensional accuracy, material integrity and long-term service performance.
Threaded / Screwed 45° Elbows provide a 45-degree change in piping direction through threaded connections. They offer a compact alternative to welded fittings where threaded connections are preferred. Elite can supply standard and project-specific configurations in carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel and nickel alloys.
