Blind flanges are essential components used to seal the ends of piping systems or pressure vessel openings. Unlike other flanges, blind flanges do not have a bore and are typically used to stop flow or allow future expansion. At Unifit Metalloys, we are one of the most trusted blind flange manufacturers and suppliers in India, offering a wide range of materials including carbon steel blind flanges, copper nickel blind flanges, and titanium blind flanges.
What Is a Blind Flange?
A blind flange is a solid disk used to block off a pipeline or create a stop. It is bolted in place and allows easy access to a pipe when needed. These flanges are ideal for systems that may require future extensions or maintenance.
Applications of Blind Flanges
They are used across various industries, including:
- Oil & Gas
- Petrochemical
- Power Generation
- Water Treatment
- Shipbuilding
They are particularly beneficial in high-pressure environments due to their strength and tight sealing capabilities.
Types of Blind Flanges by Material
We manufacture this type of flange in several material grades to meet diverse industrial requirements:
1. Carbon Steel Blind Flanges
Perfect for high-pressure pipelines, carbon steel blind flanges offer durability and strength. Widely used in oil and gas pipelines.
2. Stainless Steel Blind Flanges
These offer excellent corrosion resistance and are ideal for food, pharma, and chemical applications.
3. Copper Nickel Blind Flanges
Copper nickel blind flanges provide excellent resistance to marine environments and are commonly used in shipbuilding and seawater systems.
4. Titanium Blind Flanges
Titanium blind flanges are corrosion-resistant and lightweight, making them suitable for aerospace and medical applications.
Key Advantages of Using Blind Flanges
- Easy removal for inspection or maintenance
- Prevents overpressure by blocking flow
- Allows future pipeline extensions
- Strong sealing for high-pressure systems
