Marine oil drilling riser with corrosion protection
I. Structure
Marine oil drilling riser with corrosion protection is produced from high-quality synthetic rubber with special ingredients, a corrosion protection layer and a marine organism protection layer.
II. Use
It is applicable to riser splash zones of submarine pipeline, ship contact zones and ice layer zones, where marine drilling operation has to be done in poor conditions, and especially applicable to oilfield exploration and utilization at locations with poor ground and marine conditions, such as tidal and continental shelf zones.
III. Working temperature
-40°C~+100°C
IV. Performance indicators
Specifications of our marine oil drilling riser with corrosion protection are in compliance with standard: Q/HOY05-2011.
