Cavitation Damage in High-Pressure Let-Down Stations: When to Specify Cavitation-Resistant Alloys
2026/03/05In high-pressure piping systems, few phenomena are as destructive—and as misunderstood—as cavitation. Unlike erosion, which grinds away material like sandpaper, or corrosion, which dissolves it chemically, cavitation attacks through ...

Vacuum Service Considerations for Large-Diameter Duplex Steel Pipes: Wall Thickness and Collapse Pressure
2026/03/04When a piping system is designed for internal pressure, failure is dramatic—a burst. When it is designed for external pressure or full vacuum, failure is often silent and sudden—collapse. This distinction is critical when specifying large...
