The drilling rotary hose, made according to API Spec. 7K standard, applies for flexible hose connection between the top of oil drilling stand pipe and vertical moved swivel joint in well drilling, well cementing, work-over and down hole servicing operation, and also for adjusting the installation mistake between drilling pipe line and stand pipe to avoid shake. It also applies for high pressure oil or water base mud with the lowest aniline point of 60º C from the swivel pipe in high pressure, and down-hole operation high medium such as water, oil and mud etc...A, B, C Rank Well Drilling Rotary Hose Specification and Basic Parameters I.D.
