Industry forged Blind Flange hot sales

Blind flanges are used to close off the ends of pipes, valves, or other
equipment, providing a secure seal.
Blind Flanges – The Essential Pipeline Closure Solution
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)
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

Installation Best Practices
1. Gasket Selection Guide:

RF Flanges: Use ring gaskets (RTJ for high-pressure)

FF Flanges: Require full-face gaskets to distribute bolt loads

2. Critical Placement Locations:

Upstream/downstream of block valves

Equipment nozzle termination
