What Makes Corrugated Metal Gaskets a Reliable Solution for High Temperature Sealing?

A corrugated metal gasket is a sealing component pressed from thin metal sheet into a wave-like profile, built to compress and recover under load so it keeps a tight seal between flange surfaces even as temperature and pressure shift during operation.

How the Corrugated Profile Creates a Seal

When compressed between two flanges, the corrugated metal core generates contact pressure at each wave crest rather than across a flat surface. This concentrates sealing force where it matters most, compensates for surface irregularities and thermal expansion, and lets the gasket recover slightly as pressure and temperature fluctuate during service.

Gasket Construction Types

Why It Holds Up Under Heat and Pressure

• Excellent high-temperature resistance in boilers, furnaces, and steam systems
• High-pressure sealing capability for pipelines and pressure vessels
• Strong elastic recovery that compensates for flange movement
• Chemical and corrosion resistance depending on metal selection
• Long service life with lower maintenance and replacement costs

Where Corrugated Metal Gaskets Are Used

Corrugated metal gaskets are common across petrochemical pipelines and reactors, power generation equipment such as boilers and steam turbines, chemical processing systems, oil and gas pipelines and offshore platforms, and heat exchangers that see repeated temperature cycling.
