Wholesales Forged Steel Blind Flange Supplier China - China

What Are Blind Flanges? Blind flanges (also termed “closure plate flanges”) serve as permanent or temporary termination points in piping systems.

Unlike standard flanges, they feature a solid center without a borehole, creating an impenetrable seal when bolted to pipe ends, valves, or pressure vessels.

At JSFITTING, we manufacture industry-compliant blind flanges in all sizes and pressure classes, offering three sealing face variants: Flat Face (FF) Raised Face (RF) Ring-Type Joint (RTJ) Blind flange Our Blind Flanges Core Features & Benefits 1 - Flow Isolation No central opening ensures zero media leakage—critical for system maintenance or pressurization testing.

2 - Multi-Functional Adaptability Convertible to slip-on flanges via drilling Threadable for threaded flange applications 3 - Material Versatility Available in: Carbon Steel (ASTM A105) Stainless Steel (A182 F304/316) Alloy Steel (F11/F22/F91) 4 - Pressure-Containment Ready Designs comply with ASME B16.5/B16.47 pressure ratings from Class 150 to 2500 - Key Applications Oil & Gas Platforms Pipeline pigging isolation Wellhead termination Chemical Plants Reactor vessel sealing Water Treatment Pump discharge termination System expansion cap points More blind flange Application, please click here.
