Diameter (DN/INCH)	DN10 - DN2000 / ½In - 24In / S.A 12In - 60In
Materials	Carbon Steel (ASTM A105, P235GH, P245GH, P250GH, P265GH, ST37-2), Stainless Steel (ASTM A182, 304, 306)
Standards Compliance	ASME, EN, JIS, DIN, BS, KS, GOST, SABS, ATK
Surface Coating	Black paint, Galvanize, Grease, Epoxy paint

Applications in Industrial Systems

Blind flanges are critical components in piping systems where temporary or permanent sealing is required. They are commonly used in the following scenarios:

• System Expansion: Providing access points for future pipeline extensions or modifications.
• Maintenance and Inspection: Allowing easy removal for cleaning, testing, or component replacement.
• High-Pressure Environments: Ensuring secure seals in oil and gas, petrochemical, and power generation sectors.

Installation and Maintenance Best Practices

Proper installation is crucial to ensure the effectiveness of blind flanges. Follow these steps for optimal performance:

1. Preparation: Clean flange faces and gaskets to remove debris. Use a gasket compatible with the system's fluid and pressure (e.g., NIST-certified materials).
2. Alignment: Match bolt holes and insert bolts. Ensure the correct grade and number of bolts as per the flange rating.
3. Tightening: Use a torque wrench to apply even pressure in a crisscross pattern. Refer to manufacturer guidelines for torque specifications.
4. Testing: Conduct pressure tests post-installation to verify leak-proof seals.

Regular maintenance, including inspection for wear and corrosion, is recommended to prolong the lifespan of blind flanges.
