Imantt's Sliplining with Reinforced Thermoplastic Pipe (RTP) restores your pipeline's full operating pressure and structural integrity — zero open-trench, zero production shutdown, 50-year design life.
A proven 4-stage trenchless protocol engineered for zero-defect execution in demanding O&G environments.
CCTV internal survey + fitness-for-service analysis to determine host pipe condition and define liner parameters.
Mechanical pigging and high-pressure cleaning to remove scale, deposits, and debris. Critical for liner seating integrity.
Continuous RTP sections are precision-jointed with mechanical fittings to form a seamless liner sized to the host pipe.
RTP liner pulled via hydraulic traction. Annular grouting where required, followed by pressure testing and return-to-service.
| Parameter | RTP Sliplining (Imantt) | Carbon Steel | Result |
|---|---|---|---|
| Max Operating Pressure | Up to 3,000 PSI | Degrades with corrosion | Imantt Advantage |
| Design Life | 50+ Years | 15–20 Years | 3× Longer |
| Corrosion Susceptibility | Zero (polymeric composite) | High (electrochemical + MIC) | Immune |
| Installation Method | Trenchless — no excavation | Open trench required | No Disruption |
| Chemical Resistance | H₂S, CO₂, hydrocarbons, brine | Limited — requires coatings | Imantt Advantage |
| Temperature Range | −20°C to +85°C | Standard range | Comparable |
| Compliance | API 15S / 15SA / 15SIH · ASTM D2990 | API 5L · ASME B31.4/B31.8 | Fully Certified |
Polymeric composite construction is inherently immune to electrochemical and microbiological corrosion. No cathodic protection. No derating.
Restore maximum allowable operating pressure to original design values and keep assets in full production without derated flow restrictions.
Trenchless insertion eliminates the civil mobilization cycle. Projects complete in days, not months. Faster return to full operations.
No land clearance. No spoil disposal. No soil contamination risk. Dramatically lower ecological impact vs. dig-and-replace methods.
Lower total cost of ownership over 50 years. Eliminate recurrent replacement cycles and associated coating and inspection costs.
Multi-layer RTP structure conforms to bends and directional changes without structural compromise — ideal for complex brownfield geometries.
From onshore gathering systems to high-pressure flowlines, Imantt's sliplining performs across the full asset lifecycle — brownfield rehabilitation, capacity restoration, and pipeline life extension.
Restore corroded crude transfer lines without halting production. Maintain throughput throughout rehabilitation.
High-pressure gas lines rehabilitated with H₂S- and CO₂-resistant RTP. Zero stress corrosion cracking risk.
Aggressive brine and injection water service. Chemical resistance eliminates internal scaling and pitting.
Mixed-phase lines where fluctuating pressures accelerate metallic fatigue and accelerate corrosion failures.
We integrate RTP, Primus Line, and polymeric liner systems — selecting the right technology per asset condition, not locking you into a single product.
From engineering design and procurement to construction and commissioning, Imantt delivers turnkey non-metallic infrastructure projects.
Post-rehabilitation monitoring, SCADA integration, and lifecycle integrity services ensure performance across the full 50-year design life.
Deep regional expertise in Colombia, Venezuela, Peru, and Ecuador — we understand the operational, regulatory, and logistical realities of brownfield LATAM environments.
Established operations and supply chain infrastructure across Latin America enable rapid mobilization for both greenfield and brownfield programs.
