ASTM A403 / A403M WP316 Stainless Steel Pipe Fittings 4 Inch Long Radius Pipe Elbow 90°
Our 4 Inch 90° Long Radius Elbow is a high-performance stainless steel pipe fitting, strictly manufactured in accordance with ASTM A403/A403M standard and made of premium WP316 stainless steel. As a key component for changing fluid flow direction in industrial pipelines, it features a long radius design (CLR = 1.5×4 Inch) to ensure smooth fluid transmission, minimal pressure loss and no medium accumulation, perfectly suitable for 4-inch industrial pipeline systems.
WP316 stainless steel, containing molybdenum element, offers superior corrosion resistance, especially against pitting, saltwater, chloride and chemical media, making it ideal for harsh environments such as coastal, marine, chemical and pharmaceutical industries. The elbow adopts precision forming and seamless processing, with uniform wall thickness, high structural strength and excellent weldability, compatible with standard butt-weld connection to ensure tight sealing and long-term stable operation.
