Gaskets are mechanical seals that can fill the space and any irregularities between two or more surfaces. They likewise help in preventing leakage from or into the objects while they are being subjected to different levels of compression.
While they are intended to fill spaces and prevent leaks, gaskets must be installed and applied correctly for them to perform their mentioned purposes. Without proper installation and application, gaskets are expected to suddenly fail and affect the overall condition of the objects or systems that utilise them. Damages and injuries might even happen due to improper installation and application of gaskets.
If you want to achieve a leak-free gasket installation and application, then here are some helpful tips that you can consider and apply.
Utilise Appropriate Material
Before the installation of gaskets, you must know first the compatible gasket material for your application. Some gasket materials may not easily conform to flange surfaces. Others might not even flow effectively into joint imperfections once they are compressed. For leak-free gasket installation, you must ensure that the material can fit with flange surfaces. It must also contain low required-seating stress for proper application. It must likewise be durable enough to resist changes in temperature and pressure.
Regulate Clamping Forces
One element that must be regulated in terms of gasket applications is the clamping force. If the clamping forces are not distributed properly, your gasket might leak and cause unwanted issues to the objects. Alternatively, clamping forces that are well-distributed can effectively promote less leakage among various gasket materials. And speaking of gasket materials, the gasket that you will be using must have low material factors so that the clamping force can be reduced in holding the seal.
Cut Flaws and Scratches
Radial flaws and scratches in gaskets, which can be found in the flange near the outer edge, must be removed and eliminated to avoid leak problems. Whenever the pressure is high, the outer portion of the gasket must be the only one that is clamped thoroughly. However, if you cannot cut and eliminate flaws and scratches, then you may want to fill them with a gasket material that has a high compression ratio.
Maintain Clean Flanges
Flanges are integral to the installation and application of gaskets. And for the gaskets to be effective, your flanges must be free from any dirt caused by daily use. The dirt on these flanges may be comprised of leachable solids and oxides that can promote the development of leak paths. Aside from being clean, the flanges must be stiff enough so that the gaskets will most likely not unload.
Tighten the Bolts Correctly
The bolts used for the gasket application must be tightened uniformly so that the gasket can effectively do its functions without expecting any leaks or problems. They must likewise be tightened in one-third increments to ensure proper bolting patterns are followed.
