CUSTOM SOLUTIONS
In most situations, Colt can provide online leak sealing and repair solutions that allow critical equipment to remain in service. The appropriate method depends on the equipment, leak, pressure, temperature, materials and operating conditions.
We provide engineered online leak repair solutions for challenging pressure and temperature conditions. Contact Colt with the equipment and operating details so the appropriate repair approach can be evaluated.
Our professionals know how to manage valve repair and sealing solutions without shutdown, including valve-packing repairs and other engineered approaches based on the specific valve and operating conditions.
Colt provides online leak-sealing solutions for certain transformer and power-equipment leaks and the equipment can remain energized and in operation, when safe conditions can be maintained.
If conditions are safe to do so – absolutely. COLT provides line-stopping and isolation solutions designed to isolate portions of a water system while maintaining service elsewhere in the network.
