Profile: Sanghvi Overseas is a manufacturer of carbon steel, alloy steel and stainless steel forgings. We are an ISO 9001:2008 certified company. Our different types of flanges include welding neck flanges, slip-on flanges, socket weld flanges, threaded flanges, lap joint flanges, blind flanges, and orifice flanges. Welding neck flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications.
