We offer These Flanges as per DIN, ISO, JIS or ANSI Standard.

Carbon Steel Long Weld Neck Flanges are used extensively in high-temperature and high-pressure services because of their heavy-duty construction and long neck, which gives maximum reinforcement at the flange junction. These flanges are used extensively in oil and gas, petrochemical, power generation, and shipbuilding industries, among others. They are particularly suitable for use in pipelines that transport dangerous or corrosive fluids. Their construction reduces stress concentration and thus are appropriate for use in high-stress piping systems, heat exchangers, and reactors. They are also used in applications that demand frequent maintenance and inspection.
