Introducing RTP

What is Reinforced Thermoplastic Pipe?

Ratnaflow RTP on a reel

1 · Liner pipe

A thermoplastic inner tube (PE100, PERT, PA11, PA12 or PVDF) that carries the fluid and never corrodes.

2 · Reinforcement

Glass fibre, steel cord, aramid or carbon fibre tapes wound around the liner to carry pressure.

3 · Outer jacket

A UV-stabilised thermoplastic cover that resists abrasion and the environment.
