Corrosion is the primary factor affecting the longevity and reliability of pipelines that transport crucial energy sources throughout the global. The average annual corrosion-related cost is estimated at $7 billion to monitor, replace, and maintain these assets. The corrosion-related cost of operation and maintenance makes up 80% of this cost. Learn how to prevent, mitgate and reduce corrosion cost. 


Identifying and selecting the correct seal for the application is vital in ensuring the integrity, safety and longevity of fluids passing through pipe penetrations, pipeline transmission, distribution and process piping systems.


Pipe Penetration seals are a modular, elastomer sealing system that creates a permanent, hydrostatic seal for nearly any cylindrical object as it passes through a barrier (wall, floor or ceiling).
