Ratnaflow RTP cut-away showing liner pipe, reinforcement and jacket layer
What is RTP

Multilayer, corrosion-resistant pipe. Up to 2,000 m without a joint.

Ratnaflow RTP combines a thermoplastic liner, a contra-helically wound reinforcement of glass fibre, steel cord, aramid or carbon fibre tape, and a UV-stabilised outer jacket.

Because the pipe is flexible it is made in long continuous lengths and wound onto spools, so a line goes in with a fraction of the joints a steel line needs.
