Intended application and service environment
Describe the duty and any operating conditions that affect selection.
Dimensions, connections and material requirements
Share a drawing or project specification if available.
Quantity and required documents
Include the items to supply and any applicable project standards or approvals.

For a quotation, also include the quantity, delivery destination and required delivery window. List project specifications and documents needed for your review.

Technical details

Large GRP storage tanks are fabricated on site by filament winding, jetting molding and contact molding, using fiberglass reinforcement and resin.

Dimensions and design conditions

Confirm the tank diameter, working volume, design pressure or vacuum, and operating temperature against a tank-specific drawing and datasheet. Ask IFGS to identify the applicable design conditions and document revision in the quotation.

On-site fabrication

Discuss the available working space, site access and installation sequence with IFGS. Request the proposed reinforcement and resin system, fabrication arrangement and design documentation for the project.

Information for an application review

For proposed oil storage, oilfield wastewater or chemical storage applications, provide the stored fluid, concentration, operating temperature and required working volume. Ask IFGS to confirm material compatibility and the conditions covered by the proposed design.

See the large GRP storage tank catalogue entry for the related product overview. Request technical documents for a specific tank.
