DIN2632 PN10 Weld Neck Flange mainly increase the rigidity and bearing capacity of the flange due to the higher neck. Its purpose is to transfer the pressure of the pipeline, thereby reducing the high stress concentration in the flange base, butt-welded flanges, also known as high-neck flanges, have greater rigidity and are suitable for occasions with higher pressure and temperature. The main production processes include integral forging, forging manufacturing and casting, rolling and so on. The main production equipment includes lathes, drilling machines, CNC machine tools, etc. Applications: Boiler and pressure vessel, petroleum, chemical, shipbuilding, pharmacy, metallurgy, machinery, stamping elbow food and other industries. On-site installation is more convenient, and the process of welding seam scratching can be omitted. According to the standard, there are mainly flat butt-welded steel pipe flanges---GB9115.1, and convex face-welded steel pipe flanges---GB9115.6. DIN2632 PN10 Weld Neck Flange is your good choice.
