Blind Flange
PRODUCT PARAMETERS
The Blind Flange is a core sealing component in piping systems designed to close the pipeline end and isolate pressure. Manufactured through an integral forging process, it features a full-face sealing structure that blocks the flow of media.
It is suitable for harsh industrial conditions involving high temperature, high pressure, and corrosive media. Applications include pipeline end sealing, system maintenance, and temporary isolation. Full specification customization is available.
Application Fields: Widely used in petroleum, chemical, oil and gas transmission, power and energy, metallurgy, shipbuilding, pharmaceutical, heating systems, and long-distance pipelines. Ideal for steam, petroleum products, gases, flammable and explosive media, and corrosive substances. Especially suited for critical scenarios like pipeline end closure, system maintenance isolation, and temporary sealing.
