Exporter of Buttweld 3D Bend Fittings | ASME/ANSI B16.9, ANSI B16.28, MSS-SP-43
A Buttweld 3D Elbow is a critical component in piping systems, designed to redirect the flow of fluids or gases at an angle while maintaining efficiency and minimizing disruptions. Characterized by a centerline radius that is three times the nominal diameter of the connected pipe, this type of elbow ensures smoother transitions with minimal pressure drop and reduced flow turbulence. Its design is particularly advantageous in applications requiring long service life and high flow efficiency, such as in the oil and gas, petrochemical, and power generation sectors.
Constructed from materials like carbon steel, stainless steel, and specialty alloys, 3D bends are engineered to handle various pressures and temperatures. Their seamless or welded construction complies with global standards such as ASME B16.9, ensuring reliability and performance across diverse industrial environments.
Ample Alloys committed to delivering the highest quality Buttweld 3D Bends by adhering to stringent manufacturing and quality control policies. We prioritize the use of premium-grade materials such as carbon steel, stainless steel, and alloys to ensure durability and performance under diverse operating conditions. All products are manufactured in compliance with international standards like ASME B16.9 and MSS SP-75, ensuring precise dimensions, superior strength, and reliable performance.

- A 3D Elbow refers to a pre-fabricated elbow fitting with a defined angle (e.g., 90°, 45°), which also follows a 3D radius.
- Cold Bending: A process that involves using specialized machines to bend the pipe at room temperature.
- Hot Bending: Involves heating the pipe to a specific temperature to make it more malleable before bending.
- Induction Bending: Uses electromagnetic induction to heat the pipe locally, making it easier to form the bend.
