PTFE-lined chemical hose wanted

We are interested in 300 meters of PTFE-lined flexible hoses, for
experimental use in the ocean near Aukland, New Zealand. Ideally, the hose will be reinforced with stainless steel coils and/or fiberglass braid.

The hose must be as thick (WT) and/or thermal insulative (W/m/K) as high as possible because we want to minimise heat loss and tolerate pressures as high as 150 psi.

While the internal fluid temperature may be as high as 200 degree C, the outside ocean water temperature will be < 20 degree C. So there will be a strong temperature gradient across the wall. +130 deg C temperature tolerance may thus be okay for all but the thick PTFE inner layers.

Please send costs and technical details for 300 meters of ~100mm ID, ~150mm ID, ~200mm ID sections of such composite flexible hose.

If hose sections are very long and must be coiled, please include bending radiuses. Pipe sections should be as long as possible. How long could they be? 300 meters?

Yours truly,
