A buttweld 90 degree long radius elbow is a type of pipe fitting that is used to change the direction of flow in a pipeline by 90 degrees. The elbow has a longer radius than a standard 90 siku darjah, which helps to reduce friction and flow resistance in the pipeline. The fitting is typically made from steel or other alloys and is designed to be welded to the ends of two pipes. This creates a permanent and leak-free connection that is ideal for use in high-pressure applications. The buttweld 90 degree long radius elbow is commonly used in the oil and gas industry, as well as in power generation and other industrial applications.
