CUSTOM FRP FABRICATION
Made-to-Order FRP & Dual-Laminate Equipment
Troy Dualam Inc. fabricates made-to-order FRP and dual-laminate equipment for corrosive industrial service at its Elizabethtown, Ontario shop. Shop-fabricated products include custom tanks and vessels, process piping and spools, ducting, scrubbers, towers and other project-specific equipment. Materials, laminate construction, interfaces, inspection and testing are defined from the service conditions and project requirements.
Custom FRP Manufacturing Capabilities
Tanks and Vessels
Custom FRP and dual-laminate tanks and vessels designed around chemistry, dimensions, pressure or vacuum, loads, connections and site conditions. Explore Custom FRP Tanks & Vessels.
Piping, Spools and Ducting
Custom FRP and dual-laminate spools, fittings, headers, manifolds and duct sections fabricated to approved dimensions and documented service requirements. Explore FRP & Dual-Laminate Piping.
Scrubbers and Towers
Custom FRP and dual-laminate scrubbers, absorbers and process towers with project-specific connections, supports and internals. Explore FRP Scrubbers & Packed Towers.
Dual-Laminate Equipment
Thermoplastic-lined equipment in which the project-selected liner provides the chemical barrier and the structural FRP backing carries the loads. The complete liner and laminate system is selected for the documented chemical and operating service. Explore Dual-Laminate Tanks & Vessels.
Materials Selected for the Complete Service
Conventional FRP uses a project-selected thermoset resin system, commonly vinyl ester, with a resin-rich corrosion barrier and a separate load-carrying FRP laminate. Dual-laminate construction uses a project-selected thermoplastic liner backed by structural FRP.
Material suitability is evaluated against the complete fluid or mixture, concentration, temperature, contaminants, solids, operating cycle, and upset or cleaning conditions. Candidate thermoplastic liner families can include PVC-U, CPVC, PP, PVDF, ECTFE, FEP and PFA, subject to compatibility with the complete service.
Materials Matched to Documented Service Conditions
What to Provide for Project Review
To define the fabrication scope, provide the available project information:
- Equipment type, quantity and intended function
- Complete fluid or mixture, concentration range, contaminants, solids and cleaning chemicals
- Normal, design and upset temperatures; density or specific gravity; operating level and capacity
- Internal pressure, external pressure or vacuum requirements
- Dimensions, orientation, drawings, nozzles, flanges, spool isometrics and tie-in points
- Agitation, internals, connected-equipment loads, supports and foundation details
- Wind, seismic, snow, environmental exposure, shipping limits and site access
- Applicable code, project specification, certification requirements and owner standards
- Required inspections, testing, quality records and turnover documentation
- Any separately defined field-assembly or installation scope
Fabrication Methods & Project-Specific Quality
Fabrication methods selected for the design
TDI provides project-defined engineering support and shop fabrication. The fabrication method is selected for the approved design and geometry. Methods can include hand lay-up (contact moulding), filament winding for suitable cylindrical components, thermoplastic forming and welding for dual-laminate liners, secondary bonding, fitting and spool fabrication, controlled curing and shop assembly.
Project-specific quality and inspection
Fabrication is performed under controlled procedures. Quality controls are established for the applicable equipment, design basis and project quality plan. Depending on the scope, they may include material traceability, resin mixing and cure records, visual and dimensional inspection, laminate-thickness checks, Barcol hardness or acetone-sensitivity checks, thermoplastic-weld inspection, holiday or spark testing, and leak or hydrostatic testing.
Inspection, testing, documentation and acceptance requirements are confirmed for each project rather than represented as universal tests.
ASME RTP scope
Troy Dualam Inc. holds an active ASME RTP Certificate of Authorization for shop fabrication within its stated scope: reinforced thermoset plastic corrosion-resistant vessels fabricated using hand lay-up and filament winding, including vessels with fabric- and chemically bonded thermoplastic linings used in dual-laminate construction.
ASME RTP-1 applicability and use of the ASME Certification Mark with RTP Designator are confirmed for each project. The certificate scope does not include piping, ducting, field fabrication, field assembly or field repair. Review Troy Dualam’s Certificate Scope.
