Cosmic Alloys is leading manufacturer, exporter, stockist and supplier of weldneck flanges or weldneck raised face flanges in india.When connecting pipes, tubes, and valves in a pipeline system, flanges act as structural components. An extensive tapered hub or bore makes up a weld neck flange. Superior strength and increased hardness are features of these flanges. Both high and low pressure and temperature applications make extensive use of them. When pipes are moved erratically and violently inside a system, the long tapered hub of the Wnrf Flange provides structural support for the pipes.Flanges also aid in reducing low cycle fatigue, which is another problem brought on by extending the line. The stainless steel weld neck flange has excellent corrosion and oxidation resistance in all environments. Superior tensile and yield strength can be found in these flanges. They are simple to machine or extend. The best producers of Weld neck flanges in India are us. Our organisation strives to create the greatest products that are affordably priced and available to everyone.
In order to increase the carbon content, a carbon steel weld neck flange was created. These flanges have improved strength and ductility as a result of the increased carbon present. Their melting point is likewise low. A leak-proof seal is provided to the piping system by the flange in weld neck pipe flanges. These flanges have holes cut into them to make the inner diameter match the pipe joining. Because of this, fluids or gases can flow smoothly and with little turbulence. Reduce the surface area on the seal by using a raised surface on a raised face weld neck flange that is located above the welding area. In order to form a solid joint, this helps apply pressure to the flange junction.
The upper surface of the Flat Face Weld Neck Flange is entirely flattened through machine work. When they are fastened or torqued, some flanges experience bending pressure that damages or destroys them. When connecting pipes of various sizes together in piping systems, a reducing weld neck flange is frequently employed. The diameter of the pipe may also be decreased by using these flanges. In hostile and volatile settings, the Long Weld Neck Flange is the best option. Refineries for the processing of petroleum, oil, gas, and chemicals frequently use these flanges. We are one of the few companies that produce Long Weld Neck Flanges using the best raw materials and cutting-edge technologies.
