Description
Product Description ASME B16.11 Elbow
ASME B16.11 Elbow Socket Weld Elbow is used in piping systems to change the direction of flow at an angle of 90° or 45°. Designed for small bore piping, these fittings are suitable for high-pressure and high-temperature applications. Manufactured according to ASME standards, they ensure precision, durability, and safety in operations.
Key Features:
- Material: Available in Carbon Steel, Stainless Steel, Alloy Steel, and other custom materials.
- Sizes: Typically produced in sizes between 1/8″ and 4″.
- Pressure Ratings: Available in Class 3000, Class 6000, and Class 9000.
- Connection: Socket weld for a secure and leak-proof joint.
- Angles: Standard angles include 90° and 45°.
- Standards: Compliant with ASME B16.11 and other international standards.
