Stainless Steel Buttweld Pipe Fitting， ASTM A403 WP310S 90 Degree LR Elbow
The stainless steel 310S elbow is a type of pipe fitting that is commonly used in various industries for changing the direction of the flow of fluids or gases. It is made from stainless steel alloy 310S， which is a high-grade austenitic stainless steel known for its excellent resistance to high temperatures， corrosion， and oxidation.
The 310S elbow is designed to facilitate the smooth flow of fluids or gases through piping systems. It typically has a 90-degree bend， although other angle options such as 45 degrees and 180 degrees are also available.
Key features of the 310S elbow include its high strength， durability， and ability to withstand extreme temperatures. This makes it suitable for applications in industries such as chemical processing， oil and gas refineries， power generation， and food processing.
The 310S elbow can be welded or threaded onto the pipes to provide a secure and leak-free connection. It is available in various sizes and wall thicknesses to suit different piping requirements.
