Finite Element Analysis (FEA) is extremely important in critical seal design. JST conducted PR2 tests as per API6A, as well as FEA to its FS seal, S seal, valve stem packing seal, valve face seal. So why FEA is important and necessary? FEA capabilities make possible: 1. Seal failure prediction from cracks, leaks, or deformation, allowing a better-designed product or reverse-engineering of existing...

Choosing the right seal for your application is not easy. If you want a reliable and long-lasting performance, it’s crucial to consider the following operational conditions. Working Pressure: High pressure applications require higher durometer seals to resist extrusion. Working Temperature: Different elastomers have different low and high temperature capabilities. Installation Parameters...

In oil and gas well completion, production, or workover operations, controlling fluid communication between the annular area (the space between the casing and production tubing) and the interior of the production tubing is critical. To achieve this, the Seal Stack serves as an efficient sealing solution, widely used in wellbore tools, especially in key equipment like sliding sleeves. This article ...
