Rotary Hose

Detailed parameter

1. Function: apply for flexible hose connection between the top of oil drilling standpipe and vertical moved swivel joint in well drilling, well cementing, work over and downhole servicing operation, and for adjusting the installation mistake between well drilling pipeline and standpipe to avoid of shake, also apply for the high pressure oil or water base mud with the lowest aniline point of 66℃ from the swivel pipe in high pressure, and downhole operation high medium such as water, oil and mud etc.

2. Structure: made in inner rubber layer, carbon fibre reinforcement layer, mid rubber layer, steel line reinforcement layer (steel catenarian reinforcement layer) and carbon fibre outer rubber layer.

3. Classify: steel reinforcement model and steel catenarian reinforcement model.

4. Exeutive standard: API Spec 7k SY/T 5469-92
