Oil Well Drilling Tools

Oil Well Drilling Tools API Tool Joint for Drill Pipe with High Machining Accuracy Tool joint is an important tool to connect up drill pipes; however, it is one of the weakest part of a drill stem because it has to bear alternating tensile stress and alternating torque during the whole process of well drilling. Thus requirements of best wear resistance, best welding and best mechanical properties are highly important to tool joints. Tiptop tool joints possesses high accuracy

Oil Well Drilling Tools Crossover Sub for Drill Pipe, Drill Collar and Kelly Crossover sub is mainly used to connect upper and lower drill tools in different connectors in drilling operations. Also it can be used to protect other tooling in drill stem (called saver sub) or be used to deliver outgoing air to the bit face just above the bit (called bit sub). The length of crossover subs is generally measured from shoulder to shoulder. Typical lengths range from 6" - 28" long

Drilling Tools Lifting Sub, 18° and 90° Shoulder, API Connection The Lifting sub is a tool for lifting down hole drilling tools such as drill collars, drill pipes etc. in oil, gas and geology field drilling operations. The structure is divided to two types: "A" and "B". The shoulder of Type A is 18°, type B is 90°, which could be chosen according to the elevator structures. The connections should suit to the drill string which is connected to it. The lifting groove is clamped

Top Drive Saver Sub for Lower IBOP, Low Temperature, 187~219mm Top Drive Saver Sub is a kind of sub connected with Lower IBOP and drill pipe, mainly used in the top drive system. Not only acting as crossover sub, but also protecting lower IBOP. Top drive saver sub can be divided into general top drive saver sub and low temperature top drive saver sub. Tiptop top drive saver subs are manufactured to customers request, based on API requirements. The top drive sub serves as the

High Pressure IBOP for Top Drive, Upper / Lower Safety Valve IBOP for top drive can be divided into Upper IBOP and Lower IBOP; they are control valves which are used with the top drive system. Usually the two valves connected to the top drive drilling device. The IBOP adopts high reliable metal seal. So it can bear high pressure upward and downward. The working pressure can be achieved 10000 psi or 15000 psi. When well kick occurring, The upper IBOP can be closed by remote
