It’s no secret that gaskets were designed to prevent gas and fluid leaks for flange face and joints. In fact, they were developed because there’s no way to create a leak-proof joint without using them. Custom gaskets are designed to provide compressible material that fit precisely between the faces of a joint, particularly flange faces, to combat internal pressure and to create a reliable seal.
At Precision Cutting Service, we’ve manufactured hundreds of different types of gaskets, among them constant seating stress gaskets. Here’s a bit more information about them.
Uneven Loading on Gaskets
Often, when the flanges of a joint are bolted together there can be an uneven load on the gasket, causing issues down the road. Improper loading on gaskets will put unnecessary pressure on their outer edges, causing an uneven compression. However, with constant seating stress gaskets, you’ll minimize maintenance costs and issues caused by vibration and high internal pressures.
Uniform Sealing Stress
Some applications require uniform sealing stress, and constant seating stress gaskets can provide this by inserting a steel annulus between the flanges that completely resists compression. Doing this creates a small gap on either side of the annulus that’s then filled with the custom gasket.
Often, constant seating stress gaskets are manufactured out of vermiculite or graphite that is then layered onto a metal backing attached to the annulus. As the flanges come together, the material of the gasket is compressed, but only until the flanges close around the annulus. This makes the sealing stress completely even, providing an expanded lifespan for your joints.
Sealing Joints that Have Issues
When you replace a failed gasket, inspect it to determine where the wear and tear on it took place. If it failed on the outer edges, your joint may require a constant seating stress gasket to prevent failure or unnecessary maintenance costs in the future.
