A Comprehensive Explanation of NA Vortex Gaskets Balancing Cost and Reliability

A thorough explanation of why NA vortex gaskets are commonly adopted as standard in many utility lines!

"I want to choose a reliable gasket for the plant's steam and cooling water lines while keeping costs down." "The joint sheet cannot withstand it, but the highest performance graphite filler is over-spec." "Is there a spiral gasket that is easy to install and economical for medium and low-pressure piping?" To ensure stable operation of the plant, it is essential to maintain not only the main process lines but also the utility lines such as steam, cooling water, and compressed air. In these lines, the balance between "cost performance" and "stable reliability" is prioritized over extremely high performance. To accurately respond to such on-site needs, Nichias Corporation has developed the standard semi-metallic gasket "TOMBO No. 1834R-NA Series (commonly known as NA Vortex Gasket)." *For more details, you can view the related links.
