Expert Fiberglass Tank Nozzle Repair

Fiberglass tank nozzle repair restores or modifies the FRP connections used for piping, valves, ports, and manways. Work may include removing damaged nozzles, relocating connections, resizing ports, adding new openings, or blocking off unused nozzles. Proper repair ties the new assembly into both the structural tank shell and interior corrosion lining.

Yes. A new nozzle can be added by cutting a properly prepared tank-body port, fabricating a compatible nozzle assembly, positioning it for piping alignment, and laminating it into the tank shell. The internal corrosion barrier must also be restored so stored chemicals do not migrate behind the lining or weaken the laminate.

Repair is often appropriate when the tank body remains serviceable but the nozzle is leaking, misaligned, damaged, undersized, unused, or no longer compatible with the current piping layout. A field repair can preserve the existing vessel, reduce capital expense, and avoid the long lead time associated with replacing an entire FRP tank.

Materials are selected for the tank’s stored product, chemical concentration, and operating temperature. American Fiberglass Tank Repair works with custom blended isophthalic and terephthalic polyester, vinylester, and epoxy resins, along with fiberglass mat and veil laminates. Matching the nozzle materials and installation laminates is critical for chemical resistance and service life.

Yes. Field service can be scheduled around shutdowns, night shifts, weekends, and other planned outages. This is especially useful for chemical, water, wastewater, and process facilities where tank downtime must be tightly controlled. Crews can mobilize with resins, laminates, and repair equipment prepared for the specified tank service.

Yes. In addition to FRP nozzles, service can include manway repair, entry-port preparation, port resizing, blocking off obsolete openings, and installing new tank-body ports. Each modification is integrated into the structural laminate and interior corrosion lining to help maintain tank strength, access integrity, and chemical containment performance.

Preventing weeping requires more than attaching a new fitting. The internal area must be sealed back to the structural laminated body, and the corrosion lining must be restored with compatible resin and reinforcement. Proper surface preparation, laminate schedule, cure control, and post-repair inspection all help reduce the risk of product migration.

American Fiberglass Tank Repair provides field service across all 50 U.S. states, including Hawaii and Puerto Rico, as well as Canada, Mexico, the Caribbean, and select international situations. Strategically positioned personnel and Service-Pack mobilization help support routine repairs, planned outages, and emergency response for FRP tank assets.
