FOSV2
Full Opening Safety Valve (FOSV)
The full opening safety valve, also called TIW valves, is a crucial component in the drilling industry, designed to protect personnel, equipment and the environment during high-pressure drilling operations. It rapidly releases excess fluid or gas to prevent dangerous pressure build-up, mitigating the risk of well control events.
-
Full opening safety valve (FOSV), knows as TIW valves, is a hand control valve in drill string circulating system, and it is one of the effective tools to prevent blowout. In the drilling operation, in order to avoid malignant accidents, full opening safety valve shall be connected between drill pipes in drilling process. The special wrench of full opening safety valve may rotate 90 °according instruction to switch on and off. In well repair operation, whether need to lift the drill pipe or not, it is best to install opening safety valve as prevention.

Lifting Sub
Lifting sub is the special tools for lifting of the drill tools in petroleum, natural gas industry and geologic exploration. With their multifunctional design, lifting subs are instrumental in a wide array of lifting operations, including equipment installation, well servicing, and rigging applications.¥ 0.00Details

Sucker Rod
Sucker rod, as known as polish rod, is a kind of special sucker rod connected with sucker rod and beam hanger. It is at the top of sucker rod, need to bear the most strength, so with bigger diameter and higher steel grade than sucker rod, and the surface is very smooth.¥ 0.00Details
-
Drill Pipe
The drill pipe is a critical component in the drilling process, playing a pivotal role in oil and gas exploration. It is a high-strength tubular conduit used to transmit drilling fluid and rotational torque from the surface to the drilling bit deep below the Earth's surface.¥ 0.00Details
-
Drilling Stabilizers
Drilling stabilizers are fairly short subs which have blades attached to external surface. By providing support for the BHA (Bottom Hole Assembly) at certain points they can be used to control the trajectory of the well. The blades can be either straight or spiral in shape. Spiral blades can give 360° contact with the borehole.¥ 0.00Details
