FRP Tanks, Vessels and Sumps
CWS can extend service life of fiberglass tanks, vessels and sumps, both single-wall and dual-containment, through tank maintenance and modifications such as
- Relining
- Nozzle Repair and Repositioning
- Repair, Modifications, and Maintenance
- Field and Emergency Service
- Dual Containment Modifications
Relining
Field service teams specialize in extending the life of fiberglass tanks’ internal corrosion linings. By relining your existing FRP tanks, they can continue to safely store corrosive chemicals like sodium hypochlorite (NaClO), sodium hydroxide (NaOH), or ferric chloride (FeCl3). Any size tank or vessel can be relined, typically within scheduled turnarounds. Even steel tanks can benefit from a corrosion resistant FRP lining.
Nozzle Repair and Repositioning
Existing tank nozzles can be easily removed and replaced with the same or larger diameters, repositioned to a new location, removed and patched-over, new nozzles cut into existing tanks, typically all within a 1-day service, including curing. Existing nozzles can be modified with support gussets to receive loads like valves, instrumentation or piping. In cases where a replacement nozzle must be installed to work with existing piping, CWS Fiberglass technicians can position the new nozzle into alignment with that piping.
CWS works with tank manufacturers to ensure that the structural integrity is not compromised.
Repair, Modifications, and Maintenance
FRP tanks, vessels, sumps, ducting, scrubbers, and neutralizers can all be repaired and modified on-site by CWS Fiberglass field crews, allowing operators to have limited downtime while having the confidence that the repairs meet or exceed industry standards.
Products
All the products we use have been rigorously tested by us both in the shop and through years of service.
Derakane
Originally developed by Dow Chemical in 1965, Derakane epoxy vinyl-ester resins have become the industry standard for corrosion-resistant FRP equipment.
In the years since, high-performance derivatives have been developed for expanded the chemical environments, high-temperature performance, and improved toughness.
Derakane Signia
Building on the success of the original Derakane series, Derakane Signia resins leverage new production capabilities to modernize the resins with features including improved environmental performance, better workability, and identifiability.
