Ensuring proper operation of machines, tools and other applications requires properly functioning gaskets. This is due to the fact that malfunctions or damaged gaskets can lead to expensive repairs depending on their intended purpose. To prevent these costly mishaps, let’s explore ways for selecting and diagnosing your gaskets with precision and accuracy!
To prevent issues when selecting a gasket material or diagnosing a gasket problem, it’s critical to ensure the compatibility of the media and temperature with any prospective materials. With their susceptibility to chemical degradation and broad range of safe temperatures, there are an abundance of options for almost any combination you could come across.
Thicker Isn’t Necessarily Better
It’s a frequent misbelief that thicker materials provide better sealing than thinner ones. However, this isn’t always accurate. Thicker gaskets can be advantageous when it comes to fixing irregularities on flanges like pitted surfaces or uneven flanges; however, for all other scenarios thin material is more effective in terms of less leakage and higher blow out resistance.
Flange gaskets often leak due to inadequate torque or bolt load. Standard ANSI flanges have published tables of proven torque values, while custom designs can use formulas to estimate the necessary levels. One essential aspect is lubrication – it drastically improves the amount of required torque for a dry versus a dry bolt. Therefore, when determining necessary force and load on your bolts in relation to its material composition and size, be certain that you’ve factored in proper lubrication if needed!
