Fiberglass Tube & Epoxy Resin Tube: What Buyers Spec Before RFQ
A fiberglass tube for fluid or pressure service is a glass-fiber-reinforced epoxy tube supplied to an agreed dimensional and connection specification. Buyers confirm size basis, pressure-temperature conditions, and ends against the offered drawing—not a brochure rating.
IFGS sources composite oilfield products from licensed partner factories in China and worldwide and handles spec confirmation, procurement and pre-shipment QC. IFGS has no factory of its own; it connects buyers to licensed partner factories in China and worldwide. This buyer RFQ guide covers fiberglass tube, fiberglass tubing, epoxy tubing, and epoxy resin tube (also searched as fibreglass tube) for fluid or pressure service. It is not about small structural pultruded FRP tubes for frames or handles, and it does not claim IFGS supplies those. For the family tubing path see GRE Tubing; for the named catalogue designation see the 2-7/8 in. 2500 PSI fiberglass tube RFQ. No API monogram or certification is claimed here.

What the IFGS tube pages actually publish
Open Epoxy Resin Tube. The page says: “Fiberglass-reinforced epoxy tube supplied to an agreed dimensional and connection specification. Identify the catalogue configuration and provide the service conditions to confirm the offered drawing and pressure-temperature rating.”
The sister page, 2-7/8 in. 2500 PSI Fiberglass Tube, asks you to request that catalogue designation and to “confirm the dimensional basis, connection and applicable pressure-temperature conditions against the offered drawing and datasheet.” A designation alone is insufficient to confirm compatibility with an existing tubing string.
Both pages share the same buying logic:
- Application, fluid, and temperature conditions (with units).
- Internal and external pressure on an operating/design basis.
- Dimensions, connections, and installation interfaces.
- Drawings, inspection documents, quantity, and delivery destination.
Both also state that a technical datasheet is not published on the page. Partial information is enough to start—mark undecided fields “Not sure yet.” Request the drawing and technical data for the exact configuration offered. Catalogue figures printed elsewhere on a product page are labels to confirm against that drawing, not ratings this guide repeats.
Fluid-service fiberglass/epoxy tube vs steel vs thermoplastic
A qualitative comparison only. No ratings.

- Fiberglass/epoxy (GRE) tube. Glass fiber in an epoxy matrix for corrosive produced fluids, injection water, or transfer where steel would need heavy protection. Lighter handling than steel. The buyer must confirm size basis, pressure-temperature conditions, connection, and fluid chemistry against the offered drawing and datasheet.
- Steel tube. Familiar strength, temperature tolerance, and make-up practice. Heavier and corrosion-prone in aggressive brines or produced water unless coated or alloyed. Still the default when compression, fire, or installer familiarity dominate.
- Thermoplastic tube. Often chosen for corrosion resistance and flexible or spoolable layouts. Pressure-temperature envelope, joint family, and chemical compatibility are different from thermoset GRE. Do not paste a GRE connection list into a thermoplastic RFQ, or the reverse.
Tube vs tubing vs pipe
Buyers search “fiberglass tube,” “fiberglass tubing,” and “GRE pipe” for overlapping scopes. On IFGS pages, GRE tubing usually means a well or completion-adjacent tubular string; GRE pipe usually means rigid surface line pipe. Freeze the family before you compare bids. The terminology page GRE tubing vs GRE pipe covers that split—link, don’t rehash. Screen or slotted duty belongs on GRE Screen Tube.
Qualifying fiberglass tubing suppliers and tube manufacturers
Searches for fiberglass tubing suppliers and fiberglass tube manufacturer should turn into a document list, not a logo check. Ask any shortlisted factory (IFGS requests this from its partner factory) for:
- A dimensioned drawing for the offered size and connection.
- A datasheet for that specific size, not a generic brochure.
- The pressure-temperature basis that applies to the offer (fluid, joint, design or test basis).
- Test and inspection documents named in your tender.
- Connection detail (mating thread or joint drawing, seals, gauges).
- Packing method and delivery destination from the manufacturing site.
Buyers may ask which API Spec 15HR or 15LR language applies to a GRE tubular enquiry; request the documents that go with the offered configuration. Never label this fluid-service tube API 15S—that is spoolable RTP. This page does not claim IFGS conformance, a monogram, or any certification. For plant QA questions use the fiberglass manufacturer buyer checklist. For the family envelope bridge see API 15HR / 15LR GRE tubing RFQ. For material-class context see the non-metallic pipe selector.

RFQ field checklist
- Application and fluid: well, transfer, or surface duty; chemistry notes that affect resin and liner choice.
- Size basis: state whether you mean nominal size or finished OD/ID/wall, and request those dimensions with tolerances on one drawing.
- Operating and design pressure: internal and external, with the design or test basis and units.
- Temperature: operating and design, with units.
- Connection / end type: mating thread or joint drawing, seals, and any gauge requirements.
- Length: useful length per piece and total length, with permitted tolerance.
- Quantity, including spares and accessories.
- Destination and delivery window. Supply: the licensed partner factory selected for your order.
- Documents required: drawing, datasheet, connection information, qualification and test documents. Name any standard your tender references.
Mark unknown fields “Not sure yet”. The product pages say partial information is enough to start a technical discussion. If size basis, pressure-temperature conditions, or connection is blank, quotes will not line up. When your inquiry already names the catalogue designation 2-7/8 in. 2500 PSI fiberglass tube, use that path and confirm the designation against the offered drawing—do not treat it as a rating guarantee.
How IFGS works on this order
IFGS is a sourcing and QC partner: it connects buyers to licensed partner factories in China and worldwide and handles spec confirmation, procurement and pre-shipment QC. Set the tube family and service here, then confirm the plant and documents with the drawing and the manufacturer checklist. IFGS has no factory of its own, holds no API Monogram, and quotes no rating the catalog does not print as a confirmed datasheet. Browse IFGS products.

FAQ
Is fiberglass tube the same as GRE tubing?
Often the same material class, but procurement labels differ. “Fiberglass tube” or “epoxy resin tube” may mean a catalogue configuration; “GRE tubing” usually means a project-specific well or completion-adjacent string. Freeze the family, then open the matching product path.
Epoxy vs other resins — what do I specify?
IFGS lists this product as fiberglass-reinforced epoxy. If your tender names polyester, vinyl ester, or another resin, say so and ask which resin system the offered tube uses. Confirm fluid and temperature against that datasheet.
Can you match an existing tubing string?
A catalogue designation alone is not enough. Send the mating connection drawing, size basis (OD/ID/wall), and the pressure-temperature conditions that apply, then request a size-specific drawing and datasheet for the offered configuration.
