The ASME B16.11 Alloy Steel 2000# Threaded Union is a high-performance three-piece fitting designed for high-temperature, medium-pressure piping. Forged from Chrome-Moly grades like F11 or F22, it ensures exceptional creep resistance and thermal stability. Featuring BSP or BSPT threads and a precision metal-to-metal ground joint, it allows for easy disassembly of steam and refinery lines. Rated for 2000 PSI, it is the industry standard for maintainable joints in extreme thermal environments.
