Advantages

Why operators choose Ratnaflow RTP.

Carbon steelinternal pitting, scale Ratnaflow RTPinert thermoplastic bore
Corrosion-Free

No rust, no scaling, no cathodic protection

The thermoplastic liner and jacket resist H₂S, CO₂, chlorides and produced water, so there is no internal or external corrosion over the design life.

Fast Installation

Lay kilometres in a day

Up to 2,000 m per spool means far fewer joints. No welding, X-ray or field coating.

Lower Lifecycle Cost

Less time to install, almost nothing to maintain

Lower installation, inspection and corrosion-control costs add up over the 25+ year design life.

High Pressure

6 – 30 MPa

Contra-helically wound reinforcement tapes carry hoop and axial loads at up to 30 MPa (4,500 psi).

Flexible & Spoolable

Follows the terrain

The pipe bends around obstacles and over uneven ground, reducing fittings and bends.

up to 2,000 m on one load
Lightweight

Easier to move and handle

A fraction of the weight of equivalent steel pipe, so lighter trucks and smaller lifting equipment.

smooth liner · resists wax and scale build-up
Smooth Bore

Better flow, less energy

The smooth liner resists wax and scale build-up and lowers friction losses.
