ASME B16.9 A234 GR WPB long radius elbows
Key Features of ASME B16.9 Long Radius Elbows
Smooth Flow and Reduced Pressure Drop: Long radius elbows have a center-to-end dimension of 1.5 times the nominal pipe size (NPS), providing a smoother flow and minimizing pressure loss.
Wide Range of Sizes: Available in sizes ranging from ½ inch to 48 inches, suitable for diverse industrial needs.
High-Quality Materials: Manufactured from carbon and low-alloy steels(ASTM A234/A234M and ASTM A420/420M), austenitic and duplex stainless steels(ASTM A403/403M and ASTM A815/815M), nickel alloys(ASTM B366/B366M), aluminum alloys(ASTM B361),and titanium alloys(ASTM B363),ensuring durability and compatibility with different piping systems.
Precision Manufacturing: Each elbow is manufactured to precise dimensions and tolerances, ensuring seamless integration into your piping systems.
