What are Inconel 625 Flanges? Features & Chemistry
- Superb resistance to pitting, crevice corrosion, and intergranular attack
- High tensile and fatigue resistance at improved temperatures
- Foremost, weldability without post-weld heat treatment
Flange Mechanics: How Do Flanges Work?
Flanges act as mechanical connectors that create a tight seal around pipes or relative to pipes
and equipment. Here's how the mechanics break down:
- Sealing Mechanism: Flanges are joined using bolts and nuts, and a gasket is inserted in relation to their faces to confirm a leak-proof seal. The bolt tension compresses the gasket material, filling microscopic surface irregularities and forming a tight obstacle.
- Pressure Containment: Flanges must withstand internal pressure from the fluid or gas being transported. 625 Inconel flanges maintain structural integrity under both high pressure and fluctuating temperatures, resisting creep and fatigue.
- Load Distribution: The flange spreads the mechanical load of the bolts across a bigger surface, reducing the chances of joint failure, pipe deformation, or fatigue cracking.
- Easy Maintenance: Unlike welded joints, flanged links can be comfortably organized and disassembled, accommodating rushed inspection, cleaning, and repair of the piping workflow without cutting or grinding.
- Alignment and Fit-Up: Flanges ensure the exact positioning of piping components.
Misalignment can lead to turbulence, deterioration, and mechanical failure. Inconel 625’s high asset and dimensional stability under thermal stress ensure perfect synchronization in high-temperature services.
