Blind Flanges
VEFLOX engineers high-pressure blind flanges designed to securely terminate the ends of piping systems, valves, and pressure vessel openings. Forged as a solid steel disk with no center bore, our blind flanges withstand severe mechanical bending stress, providing absolute fluid isolation while allowing straightforward access for future line expansion or maintenance.
Detailed Technical Specifications
Spectacle Blind (Figure-8): Reversible line blind (one solid end, one open ring) used for temporary or regular operational line isolation.
DIN/EN: PN6, PN10, PN16, PN25, PN40, PN64, PN100
Stainless Steel: ASTM A182 F304/304L, F316/316L, F321, F347
Alloy & Exotic: ASTM A182 F11, F22, F51 (Duplex), Inconel, Monel, Hastelloy
Core Advantages
Maximum Stress Tolerance
Because it lacks a center bore, a blind flange is subjected to the highest internal bending stresses of any flange type. Our forging process ensures absolute structural rigidity at the dead-center.
Accessible Line Termination
Unlike welded pipe caps, blind flanges allow a pipeline to be safely terminated while retaining the ability to quickly unbolt the joint for internal inspection, pigging, or cleaning.
Future Expansion Ready
Engineers frequently cap manifolds and main headers with blind flanges to "future-proof" the system, allowing pipelines to be easily extended later without cutting steel.
