Raised Face Blind Flange
A blind flange raised face is a type of blind flange that features a raised portion around the bore, typically extending outwards from the flange’s face. This raised face serves multiple purposes, including facilitating alignment during installation and providing a surface for creating a seal when the blind flange is installed in a piping system. When a blind raised face flange is bolted against a mating flange or fitting, the raised face compresses the gasket, creating a tight seal to prevent leakage.

Raised Face Blind Flange Models
Blind Raised Face Flange Materials
Carbon steel raised face blind flange known for its strength and affordability, carbon steel blind flanges are widely used in general-purpose applications where corrosion resistance is not a primary concern.
Stainless steel blind flanges raised face are preferred for applications requiring corrosion resistance.
Alloy steel blind raised face flanges are chosen for applications involving high temperatures, pressures, or corrosive environments. These flanges offer enhanced mechanical properties and resistance to corrosion and are commonly used in industries such as oil and gas, petrochemicals, and power generation.
Design Features Of Blind Flange Raised Face
The raised face is a prominent feature encircling the blind raised face flange. This raised surface serves as a contact area for compressing the gasket against a mating flange or fitting, creating a tight and leak-proof seal when the flange is bolted in place. The height of the raised face is standardized according to industry specifications to ensure proper compression of the gasket and optimal sealing performance.
The Raised face blind flange has a solid, circular disc or plate with a machined bore to match the pipe’s diameter. The hub, located at the center of the flange, provides reinforcement and support for the bolting mechanism. The bore and hub dimensions are carefully machined to ensure compatibility and alignment with the mating flange or fitting.
Raised face blind flanges feature bolt holes arranged in a circular pattern around the perimeter of the flange. These bolt holes allow for the insertion of bolts to secure the blind flange to the mating flange or fitting.
Applications Of Raised Face Blind Flange
1. Blind flanges raised face are utilized in chemical processing plants for isolating sections of pipelines or vessels during equipment maintenance, cleaning, or inspection. They provide a secure seal to prevent the escape of hazardous chemicals and facilitate safe working conditions for operators;
2. In petrochemical facilities, blind raised face flanges are crucial for isolating process streams, reactors, and other equipment during turnaround activities. They enable efficient maintenance procedures, minimize downtime, and ensure operational safety and reliability;
3. In offshore projects, raised face blind flanges serve critical functions across various industrial applications, ensuring the integrity, safety, and efficiency of piping systems and equipment. These flanges are utilized for pipeline isolation during maintenance, repair, or pressure testing activities, enabling safe work environments and preventing fluid releases into the surrounding environment.
Blind Flange Raised Face Installation
- Align the blind raised face flange with the mating flange or fitting, ensuring that the bolt holes are properly matched;
- Place the gasket on the raised face of the raised face blind flange, ensuring that it sits evenly and covers the entire sealing surface;
- Insert bolts through the bolt holes of the raised face blind flange and mating flange or fitting. Tighten the bolts gradually and evenly in a crisscross pattern to ensure uniform compression of the gasket;
- Torque the bolts using a calibrated torque wrench. Avoid over-tightening, as this can damage the blind flanges raised face or cause the gasket to extrude;
- Conduct a visual inspection to verify that the blind raised face flanges are properly aligned, the gasket is correctly positioned, and the bolts are tightened to the specified torque.
Blind Raised Face Flange Maintenance
- Check bolt tightness periodically to ensure that the blind flanges raised face remain securely fastened;
- Inspect the raised face surface for any corrosion, pitting, or damage that may affect sealing performance. Address any issues promptly to prevent leakage or loss of containment;
- Implement corrosion protection measures to extend the service life of raised face blind flanges and maintain their integrity in corrosive environments. This may include applying protective coatings or using corrosion-resistant materials.
Advantages Of Raised Face Blind Flange
- The raised face design provides a flat and smooth surface for compressing gaskets, ensuring a tight and reliable seal. This feature minimizes the risk of leaks and ensures the integrity of the piping system;
- The raised face helps in aligning the blind flange raised face with the mating flange or fitting during installation. This facilitates proper alignment, reducing the likelihood of misalignment issues that could compromise the seal;
- Blind raised face flanges are capable of withstanding high pressures and temperatures, making them suitable for demanding industrial environments where pressure containment is critical.
