90 Degree Long Radius Elbow in 304SS & 316SS Stainless Steel with Seamless Forged Structure Compliant with ASME B16.9 Standard
Our 90-degree long radius elbow is a high-performance butt welding seamless pipe fitting, meticulously forged from premium 304SS and 316SS stainless steel. Fully compliant with ASME B16.9 international standards and certified by CE and ISO, this elbow features a long radius design (centerline radius = 1.5 * nominal diameter) that effectively reduces fluid resistance, avoids medium accumulation and pressure loss, ensuring efficient and safe operation of the entire pipeline system.
