Specification

SEODescription

The Φ325 Normal Expansion Flange with 8x80 Bolt Expansion Joint is designed for high-pressure piping systems requiring reliable thermal expansion compensation. Featuring a 325mm diameter flange, this expansion joint supports direct connection to pipelines or modules via 8x80 high-tensile bolts, ensuring robust sealing under pressures up to 25 bar. It operates within a temperature range of -30°C to +250°C and is compatible with standard industrial voltage (24V DC/120V AC). Ideal for oil/gas, power generation, and chemical processing, the High Pressure 325mm Flange excels in durability and leak resistance. Its modular design allows seamless integration with existing systems but may require precise alignment during installation. Communication interfaces like RS485 enable optional sensor integration for real-time monitoring. Key drawbacks include higher weight and limited flexibility in extreme cyclic conditions.
