Tank Maintenance

Many years can be added to the service life cycle of fiberglass storage vessels through tank maintenance and modifications such as

  • Tank Inspections
  • Relining
  • Nozzle Repair and Repositioning
  • Repair, Modifications, and Maintenance
  • Field and Emergency Service
  • Custom FRP Supports
  • Sump Dual Containment Modifications

Tank Inspections

With 25 years of experience, CWS Fiberglass inspectors perform internal and external FRP tank inspections, complete with comprehensive report and repair recommendations. Inspections can be customized to our clients’ unique requirements. With regular inspection, you can be confident that your FRP assets will remain in service for their entire life cycle.

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.

Repair, Modifications, and Maintenance

FRP tanks, vessels, 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.

Field and Emergency Service

Field service teams will mobilize to any client’s location to perform required repairs and routine maintenance. Examples of these services include nozzle repairs, tank leaks, and shell cracks.

CWS keeps an inventory of specialized resins to meet a variety of service conditions commonly found in Energy, Pulp&Paper, Chemical, and other Industrial facilities.

In emergency situations, CWS Fiberglass field service teams can be mobilized in 24 hours.

Supports

Custom FRP Supports

Existing tanks that are designed with internal piping face exorbitant costs when repositioning or adding new steel supports. Clients can save the expense of re-coating steel tanks when installing new FRP tank internal piping by using CWS Fiberglass custom FRP supports.

Sump Dual Containment Modifications

The AER mandates that all sumps require dual containment. Existing sumps can be modified using custom-fabricated FRP inserts to achieve dual containment. CWS has modified many different configurations of overflow drainage systems. Runoff trenches can be relined or piping installed using FRP to meet AER requirements.
