- High-Pressure Environments: Resisting extreme temperatures and pressures in oil & gas and power generation sectors.
Installation Guide
Proper installation of the Blind Flange ensures optimal performance and safety. Follow these steps:
- Preparation: Clean flange faces and gaskets thoroughly to remove debris or contaminants.
- Gasket Selection: Choose a gasket compatible with the fluid type, pressure, and temperature of the system.
- Alignment: Match bolt holes of the blind flange and mating flange, ensuring precise alignment.
- Bolt Installation: Insert bolts of the specified grade and number, tightening them in a crisscross pattern for even pressure distribution.
- Torque Application: Use a torque wrench to apply the manufacturer’s recommended torque values, preventing leaks or damage.
- Testing: Conduct pressure tests to verify the seal’s integrity and identify potential leaks.
Always prioritize safety in pressurized systems, adhering to industry protocols and protective measures.
