فلانش أعمى (Blind Flange)

Blind flanges are solid discs used to seal off the end of a pipe, valve, or pressure vessel opening. Unlike other flange types that have a bore for pipe passage, blind flanges are solid plates designed to withstand the full system pressure on one side. They are manufactured to ASME B16.5 with raised face, flat face, or ring-type joint facings, and are available in all standard pressure classes from Class 150 to Class 2500.

Blind flanges are commonly used at pipe ends for future expansion, at vessel manways and handholes, and for hydrostatic test isolation. They allow easy access to piping systems for inspection, cleaning, and maintenance, and can be removed to add future pipe extensions. Our blind flanges are forged with controlled grain flow and undergo 100% ultrasonic testing for material integrity before final machining.
