Flange are mainly used for connect the wellhead equipment . Christmas tree and other well control equipment .A wide variety of types including flange spool thread flange and Blank Flange etc.

Choke valve is a main component of Christmas tree and designed to control production output of the oil well, the materials of the body and components of choke valve are completely in conformity with API 6A and NACE MR-0175 Standard Specifications, and it is widely used for onshore and offshore petroleum drilling. The throttle valve is mainly used to adjust the flow and pressure of the manifold system; There are two types of flow control valves: fixed and adjustable. Adjustable throttle valves are divided into needle type, inner cage sleeve type, outer cage sleeve type and orifice plate type according to the structure; According to the operation mode, it can be divided into manual and hydraulic two. The end connection of choke Valve is thread or Flange, connected by non or flange. Choke valve falls into: positive choke valve, needle choke valve, adjustable choke valve, cage choke valve and orifice choke valve, etc.

Milling tools are used to milling fish and other downhole objects, clean up casing wall (hole wall) debris or repair casing. The principle is to grind the fish into debris under the rotation and pressure of the drill string by tungsten carbide that is welded on the cutting part of the milling tool, and debris can be recycle back to the ground with drilling fluid.
Most kinds of milling tools are common in structure, while according to different shapes of fish, corresponding cutting parts are needed. Commonly used cutting parts can be arranged in the interior, exterior and end of milling tools.
After innovative design and technological accumulation in recent years, they have met the actual needs of customers from China and abroad by virtue of reliable performance. Besides the types and sizes listed in the following content, we also welcome to produce according to special designation that can satisfy the customer needs.

Mud gate valves are solid gate, rising stem, gate valves with resilient seals, these valves are designed in accordance with API 6A standard. It is mainly used for mud, cement. fracturing and water service and are easy to operate and simple to maintain.

Plug valve is a necessary part in cementing and fracturing operation in oil and mining fields as well as similar high pressure liquid control. It features compact structure, easy maintenance, low torque, quick opening and easy operation that it is the most ideal valve among cementing and fracturing manifolds right now. (Remarks: valve can also be opened or closed easily under 10000psi.)

Kill manifold is a necessary equipment for controlling overflow and blowout, and implementing pressure control technology for oil and gas wells.
During the drilling process of oil and gas wells, once the drilling fluid in the wellbore is contaminated by the formation fluid, the balance between the static liquid column pressure of the drilling fluid and the formation pressure will be disrupted, leading to overflow and blowout.
When it is necessary to circulate contaminated drilling fluid or pump drilling hydraulic wells with adjusted performance in order to rebuild this balance relationship, but normal circulation cannot be achieved through the drill string, the drilling fluid with adjusted performance can be pumped into the well through the kill manifold to control the pressure of the oil and gas well.

Check valve is designed and produced entirely according to the requirements of API 6A 《Equipment Specifications for Wellhead and Christmas Tree》, able to be used interchangeably with corollary equipment at home and abroad that is inline with API 6A Standard. The core adopt sulfide-resistance steel and able to be used in H2S condition, valve body made by alloy steel forging with good performance. Two types of Check valves are offered by landrill: Swing type and Lift type.

Integral Blade Stabilizers are manufactured from 4145H alloy steel bar or forgings, quenched and tempered to 285-341 Brinell hardness;
Stabilizers are fairly short subs which have blades attached to their 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.
