Case Study

Petrochemical Industry Plant,

Czech Republic



November 2023



5 days


The Challenge:

Stopping of CO2 leak on pipe elbow and avoid shutdown

The Solution:


A petrochemical plant in the Czech Republic experienced a CO2 pipeline elbow leak that had the potential to take a section of the facility offline for several days. The leaking externals of a carbon steel pipeline elbow had previous unsuccessful coating repair attempts to stop the leak. Expensive downtime due to offsite repair or full replacement could be avoided with an online repair solution utilising Corrocoat products.


Following an inspection, surface preparation of contact area was undertaken onsite whilst work got underway with preparation of a 4 mm thick component (Lamination Resin 600 + Multiaxial Fiber Glass Cloth 600 g/m² in the workshop. This was then taken to site for installation and filled with Corrofill VE onsite. Strength was further bolstered with the lamination wrap over the component and application of Polyglass VE HA over the lamination reinforcement.
