Diverters for well-control while drilling in the surface layer
Diverters are primarily used for well-control while drilling in the surface layer in the exploration of oil and gas. Diverters are used together with hydraulic control systems, spools and valve gates. The streams (liquid, gas) under control are transmitted to safe zones along a given route to ensure the security of well operators and equipment. It may be used to seal Kelly, drill pipes, drill pipe joints, drill collars and casings of any shape and size, at the same time it can divert or discharge the streams in well.
Diverters offer an advanced level of well control, improving safety measures while boosting drilling efficiency. These versatile devices boast a resilient design that allows for swift and effective responses to unexpected drilling challenges such as overflows or gas influxes.

Choke Manifold and kill Manifold
·Control pressure to prevent overflow and blowout.
·Reduce wellhead casing pressure by relief function of the choke valve.
·Full-bore and two-way metal seal
·The internal of the choke is constructed with hard alloy, exhibiting a high level of resistance to erosion and corrosion.
·The relief valve helps to reduce casing pressure and protect BOP.
·Configuration type: single-wing, double-wing, multiple-wing or riser manifold
·Control type: manual, hydraulic, RTU
Kill Manifold
·Kill manifold is mainly used to kill well, prevent fire and assist in fire extinction.

API 6A Manual Adjustable Choke Valve
Our Plug and Cage style choke valve features a tungsten carbide cage as the throttling mechanism with a protective steel carrier around it
Outer Steel carrier is for protection against impacts from debris in the production fluid
The trim characteristics are an equal percentage that provides superior flow control, however, we can provide the linear trim as well on-demand
Pressure-balanced trim considerably reduces the torque required to operate the choke
Plug is fully guided at the ID of the sleeve and is rigidly attached to the stem to resist any induced vibration damage

API Low Torque Control Plug Valve
The plug valve is mainly made up of the body, the hand wheel, the plunger and the others.
The 1502 union connection is applied to connect its inlet and outlet to the pipeline (this can be custom-made according to different requirements). the precise fit between the valve body and the liner is ensured by means of cylindrical fitting, and the sealant is inlaid through the outer cylindrical surface of the liner to make sure that it is hermetically sealed.
The cylindrical meal-to-meal fit between the liner and the plunger is adopted to ensure a high fitting accuracy and thereby reliable sealing performance.
Note: even under a pressure of 15000PSI, the valve can be opened or closed with ease.

Oil and gas Production Wellhead Equipment
Single Composite Tree
Used on low-pressure (up to 3000 PSI) oil wells; this type of tree is in common use worldwide. A number of joints and potential leakage points make it unsuitable for high-pressure applications or for use in gas wells. Composite dual trees are also available but are not in common use.
Single Solid Block Tree
For higher-pressure applications, the valve seats and components are installed in a one-piece solid block body. Trees of this type are available up to 10,000 PSI or even higher if required.
