A search for rtp pipe manufacturers usually means you already want spoolable composite line pipe — not stick GRE/FRP. The risk is mixing plants that quote reels, end fittings, and API Spec 15S language on unequal sheets. Use this guide to qualify suppliers before you ask for a price.
IFGS manufactures GRE, FRP/GRP, and RTP oilfield equipment in Dongying, China. We do not claim a USA factory. This page is a global qualify-supplier checklist for RTP — it is not a field case study and does not rewrite Iraq project content already on this site.
Freeze the product: RTP is a spoolable path (API Spec 15S)
Write one line that locks scope before you shortlist RTP pipe manufacturers:
- Spoolable RTP / reinforced thermoplastic / flexible composite line pipe — buyer and tender language usually sits with API Spec 15S.
- Stick GRE / FRP tubulars or line pipe — different plant, QA, and logistics; often discussed with 15HR / 15LR. Open a separate RFQ. Never label RTP as 15HR or 15LR on the same line item.
- Fittings, couplers, end terminations — name them with the reel plan; unequal bids often hide missing end-fitting scope.
If the inquiry only says “composite pipe” or “fiberglass,” stop and split stick vs spoolable before you compare manufacturers.
How to qualify an RTP / spoolable composite supplier
1. Manufacturing capability you can audit
- Reel / liner / reinforcement construction they actually run for your diameter and pressure class.
- ITP outline for this spoolable family — not a generic ISO poster.
- Traceability for reels and end fittings as your project requires.
2. Standards language without fake marks
- Keep RTP quotes in API Spec 15S language when that is your tender frame.
- Treat website “API” adjectives as marketing until the quote pack names construction, tests, and documents you will buy.
- Do not invent monogram or listing claims in the RFQ reply — ask the plant what they will document.
3. Capacity, reels, and lead realism
- Meterage per reel vs your line plan; max OD / pressure envelope they ship on reels.
- Monthly capacity vs your schedule; coupler / end-fitting lead if special.
- Winter or desert pad handling notes if the season changes crane and truck plans.
4. Export and logistics (reels change the plan)
- Reel packing, weight, and dimensional limits for road / port.
- Destination country and Incoterm preference (buyer-owned fields — not invented here).
- Unload and staging assumptions at the pad or yard.
5. End fittings and joints
- Named end-fitting / coupler system matched to the RTP construction.
- Spare kit policy and joint / termination test scope.
- Unequal manufacturer bids often diverge here before pipe meter price.
RFQ fields that make RTP manufacturer bids comparable
- Product = spoolable RTP / flexible composite (not stick GRE/FRP).
- Spec language = API Spec 15S when that is your frame.
- ID/OD or size class; design pressure and temperature as project fields.
- Fluid / medium (incl. H₂S, CO₂, salinity if known).
- Total length and preferred length per reel; burial vs surface.
- End fittings / couplers; documentation and inspection expectations.
- Destination, packing, and unload constraints.

FAQ
Is every RTP pipe manufacturer the same as a GRE stick-pipe plant?
No. Spoolable RTP (15S path) and stick GRE/FRP (often 15HR/15LR language) are different manufacturing and logistics paths. Split the RFQ.
Should this page replace an Iraq or other field case?
No. This is a global qualify-supplier guide. Field cases stay on their own URLs.
Does IFGS have a USA factory?
No. Dongying, China only on this page.
