'safely withstand'

DIN 2627 stainless steel flanges PN 400 are precision-engineered blind flanges manufactured according to the DIN 2627 standard. Designed to withstand ultra-high-pressure conditions up to 400 bar (5800 psi), these flanges are used to terminate or isolate piping systems safely and effectively. Fabricated from high-grade stainless steels, including 304, 316, and 321, these blind flanges provide superior mechanical strength, corrosion resistance, and long service life in aggressive industrial environments. Ladhani Metal Corporation is a globally recognized manufacturer and exporter of stainless steel flanges. Our DIN 2627 PN 400 blind flanges are widely trusted in sectors such as oil and gas, chemical processing, marine, energy, and high-pressure utility systems for their durability, quality, and performance under extreme conditions. Pressure Rating: • PN 400 (400 bar / 5800 psi): Suitable for high-pressure pipelines and critical systems where absolute sealing and structural integrity are required. Flange Type: • Blind Flanges Solid, non-bored flanges used to block pipeline ends or vessel nozzles. These flanges are essential for system isolation during maintenance, testing, or future expansions. • Flat Face (FF) Flanges Flat face flanges are designed to mate with flat gaskets and flat-faced components. They provide even gasket compression and are ideal when used with cast iron or brittle materials to avoid flange distortion.
