Purpose-engineered for the dredging and marine construction industry, this flexible long-length RTP composite pipe redefines how sand, silt, mud, and dredged spoils are transported from cutter suction dredgers to disposal sites. By replacing cumbersome steel pipelines with a spoolable composite solution, contractors achieve faster mobilization and dramatically lower operational costs.
| Parameter | Specification |
|---|---|
| Composite Layer Build-Up | Thermoplastic Inner Liner + Fiber/Steel Reinforcement + Outer Protective Layer |
| Rated Pressure Capacity | Up to 32 MPa (engineered to project specifications) |
| Diameter Offering | 2 inch to 12 inch (non-standard diameters by request) |
| Temperature Envelope | -40°C to +90°C |
| Joint Assembly Type | High-pressure swaged fittings, flanged joints, or electrofusion |
The spoolable nature allows delivery in lengths that dwarf conventional pipe segments, translating to 70-80% fewer field connections compared to steel. This directly reduces labor hours, joint material costs, and connection-related failure risks during high-flow dredging.
Dredged materials are inherently abrasive. Our HDPE inner liner is formulated with advanced wear-resistant polymers that outperform standard steel in sliding abrasion tests. The smooth bore maintains low-friction characteristics over extended service periods.
The inherent flexibility accommodates wave action, tidal movements, and seabed contours without requiring articulated ball joints. Equally suitable for floating hose lines and submerged pipelines, adapting naturally to the marine environment.
We supply RTP pipe pre-cut to exact lengths specified in your dredging alignment sheets. No field cutting, no wasted offcuts. Each section arrives labeled and ready for immediate connection, streamlining mobilization and reducing on-site handling.
Traditional steel dredge pipes require hundreds of flanged joints, heavy lifting equipment, and days of assembly per kilometer. Our flexible RTP composite pipe arrives on reels in extended continuous sections, enabling a single crew to deploy kilometers in a fraction of the time.
