An Elbow Welding Outlet, often called an Elbolet, is a specialized integrally reinforced branch fitting designed to create a branch connection directly from an elbow. This unique design is contoured to fit the radius of an elbow, eliminating the need for a separate tee fitting and making it ideal for space-saving applications. Manufactured using a high-strength forging process from materials like carbon steel, stainless steel, and alloy steels, Elbolets provide a reliable, high-strength connection for high-pressure and high-temperature services. They are widely used in oil & gas, petrochemical, and power generation industries and are available with socket weld, threaded, or butt weld outlet connections.

| Elbolet Design Features |
Contoured Base: Specifically designed to fit the unique radius of a 90° or 45°
elbow. Forged Strength: Provides superior strength and fatigue resistance at the branch connection. Versatile Outlets: Available in Socket Weld, Threaded, and Butt Weld connections. Space Efficiency: Eliminates the need for a separate tee fitting, ideal for tight spaces. Standard Compliance: Manufactured per MSS-SP-97. |
Designed with a contoured base to fit perfectly onto the radius of 90° or 45° elbows, eliminating the need for a tee fitting in tight spaces.
Manufactured using advanced forging techniques to provide integral reinforcement, ensuring a high-strength, durable connection that can handle high pressure.
Available with Socket Weld (SW), Threaded (NPT/BSP), or Butt Weld (BW) outlets to easily integrate with various branch piping requirements.
Conforms to MSS-SP-97 and relevant ASTM material specifications to ensure global compatibility, quality, and safe operation in critical systems.
Available in carbon steel, stainless steel, and alloy steels to withstand corrosion, high temperatures, and harsh industrial environments.
The contoured design provides a smooth transition from the elbow to the branch, minimizing flow restriction and turbulence at the connection point.
