ASME B16.11 Threaded Tees
ASME B16.11 threaded tees are forged fittings designed for use in high-pressure piping systems. ASME B16.11 threaded tees are integral components in high-pressure piping systems, providing a threaded connection for creating T-shaped junctions in pipelines.
Threaded tees are manufactured from materials that conform to specifications outlined in relevant ASTM standards. Common materials include carbon steel, alloy steel, stainless steel, and other alloys suitable for high-pressure and high-temperature service.Threaded Tees come in different pressure classes, such as 2000, 3000, 6000, and 9000.
