45° & 90° Elbows ASME B16.11 Forged Fittings| Ample Alloys

Forged 90° & 45° Elbow Fittings | ASME B16.11, MSS SP-79, 95, 83, 95, 97, BS 3799

Socket weld 90° and 45° elbows are designed for strong, permanent, leak-tight connections in pipe systems. The elbows fit into a socket at the pipe’s end and are welded, ensuring no leakage, even under high pressure. The Socket weld 90° elbow provides a sharp turn, while the Threaded 45° elbow offers a more gradual redirection. Typically used in smaller bore pipelines (2 inches or smaller), they are ideal for high-pressure and high-temperature applications, such as in oil and gas, aerospace, and chemical industries, due to their durability and strength.

Threaded 90° and 45° elbows offer an easy solution for changing the direction of flow in piping systems. With internal threads, they screw onto external threads of the pipe, making installation and removal simple. The 90° elbow offers a sharp turn, and the 45° elbow provides a smoother transition. Often used in low-pressure systems, these elbows are suitable for plumbing, HVAC, and temporary installations due to their ease of maintenance and cost-effectiveness, though they’re not recommended for high-pressure systems.
