FEA Simulation Finite element analysis (FEA) is a computer-based technique used to calculate the performance of components in practical applications. This advanced technology can determine how components are affected by extreme temperatures and pressures, specific stresses, and aggressive chemical environments. Proficient use of FEA simulations enables accurate modeling by predicting behavior, eli...

Sour gases containing hydrogen sulfide/sulfide (H2S) can have a very adverse effect on elastomers. The elasticity that is not resistant to corrosion becomes hard and brittle, losing elasticity and sealing ability, ultimately leading to sealing failure. JST has developed various sour gas resistant elastomer materials for the oil, natural gas, and petrochemical processing industries with the third-p...

Every machine or system that relies on seals understands the seriousness of a leak or premature seal failure. The subject involves significant financial, operational, and sometimes environmental issues that require in-depth understanding. The Basics of Seal Leakage What is Seal Leakage?: Beyond the basic definition, seal leakage can be understood as any unintended escape of fluid or gas due to the...
