Gaskets for Fluid Catalytic Cracking Units (FCCU) and Hydrocracking
The increase in fuel standards, operational efficiency and stress on green resources is expected to contribute to the increase in fluid catalytic cracking requirements. This demand to increase yield requires an increase in temperature putting pressure on the performance of any sealing materials and potentially compromising safety.
Operating temperatures over 500°C (932°F), place sealing materials under significant strain and often leads to gasket failure.
Often caused by routine shutdowns, rapid temperature changes cause repeated expansion and contraction, putting unmanageable stress on gasketed joints
Gaskets contain a series of bonds holding the structure of the material together. The bonds lose their adhesion as the temperature reaches the material limits, resulting in gasket failure.
