Final answer:
When bolting a metallic flange to a non-metallic flange, material compatibility and sealing integrity are crucial. Differences in the coefficient of thermal expansion and proper sealing techniques must be considered. This practice is common in various industries and requires precise alignment and appropriate materials to prevent leaks.
Step-by-step explanation:
Where a Metallic Flange is Bolted to a Non-Metallic Flange
When a metallic flange is bolted to a non-metallic flange, it is crucial to ensure that the materials are compatible and can create a seal that is both strong and leak-proof. One of the main concerns in this application is the difference in the coefficient of thermal expansion between the two materials, which can cause issues such as gasket creep or bolt stress relaxation over time. The use of proper gaskets, appropriate bolting techniques, and sometimes insulating kits are essential to maintain flange integrity in varying temperature and pressure conditions. This application is commonly seen in industries such as petrochemical, water treatment, and food processing where piping systems involve both metallic and non-metallic components. Ensuring the correct alignment and the use of a compatible sealing material is key in preventing leaks and maintaining system integrity.
