Product Features
The Blind Flange is a solid disk used to block off a pipeline, valve, or pressure vessel opening. It is engineered for easy installation and removal, making it ideal for systems requiring frequent inspection or maintenance. Available in a range of materials, including carbon steel, stainless steel, and alloy steel, these flanges offer exceptional strength, durability, and resistance to pressure and temperature.
Key features include:
- Material Variety: Carbon steel (ASTM A105, P235GH, P245GH, etc.), stainless steel (ASTM A182, 304, 306), and alloy steel.
- Pressure Ratings: ANSI/ASME, DIN, JIS, and other international standards (PN6–PN40, Class 150–Class 2500).
- Surface Coating Options: Black paint, galvanization, grease, and epoxy paint for corrosion resistance.
- Compatibility: Designed to work with various flange types, including flat-surface and raised-surface flanges.

Applications in Industrial Systems
Blind Flanges are widely used in industries such as oil and gas, petrochemicals, power generation, and water treatment. Their applications include:
- Pipeline Sealing: Blocking the end of a pipeline during maintenance or expansion.
- System Testing: Providing a secure seal during pressure testing to ensure safety.
- Future Expansion: Allowing for temporary or permanent closure of piping systems.
- Corrosion Resistance: Available in materials like stainless steel for use in corrosive environments.
Installation Guide
Proper installation of a Blind Flange ensures a secure, leak-proof connection. Follow these steps:
- Prepare Surfaces: Clean the flange faces and gasket to remove debris.
- Install Gasket: Place a compatible gasket between the blind flange and mating flange.
- Align and Bolt: Match bolt holes and insert bolts, tightening them in a crisscross pattern for even pressure.
- Apply Torque: Use a torque wrench to meet manufacturer specifications.
- Test for Leaks: Conduct a pressure test to verify the seal.
