            • Float Valve Model F and Model GFloat Valve Model F and Model G

                Float (check) valve is usually installed in float subs (long subs bored out for a specific float) and prevent fluids from backing up in your drill string while adding/removing rods. The type available of float valve as below:
                Model F (plunger valve):Instantaneous shut off against high or low pressure, assuring continuous control of fluid flow during drilling.
                Model FC (Automatic Fill valve) Automatic feature allows drill pipe to fill from the bottom, removing the mess, hazards, and lost time from filing. When running in the hole, automatic fill feature eliminates the ‘ram effect’ preventing the down hole pressure surges that can cause formation damage.
                Model G (Full open valve, flapper type):When circulation stops, flapper closes instantly to prevent cuttings from entering drill string and plugging bit. Valve opens when the first joint is raised out of hole assuring the first joints drain and are not pulled wet. Saves mud and avoids safety hazard and downtime.
                Model GA (Differential Pressure Monitoring Valve):Hardened 1/4in. diameter tungsten carbide orifice bean insert in flapper to provide automatic partial filling of drill pipe during running in.
                Model GC (Automatic Fill Flapper Valve)Uses low carbon steel “automatic fill” key assembly that allows pipe to fill from bottom.
                Model GCA (Automatic Fill with differential pressure monitoring valve)Incorporate both GC and GA
                Model GS (non-ported flapper) and GAS (ported flapper)For high flow and erosion resistance,
                made of alloy steel and unique flapper relief to reduce flapper spring and pin wear. Option to have tungsten carbide coating on flapper face.

              • Kelly Cock ValveKelly Cock Valve

                  The MDX Ball Type Kelly Valve provides a quick, sure shutoff in the drill string that can repay the cost of the valve quickly in the mud savings and kick protection.This valve can be used as either an upper or lower kelly cock. It has an exclusive corrugated spring to insure a positive seal. Standard pressure rating is 10,000 pound test, but higher pressure ratings are available on special order. The ball is stainless steel, and closes easily. The MDX Kelly valve is full-opening, so it does not interfere with the running of tools such as core barrels or survey instruments. Its streamlined O.D. is the same as the tool joint O.D.
                  Upper Kelly Valve:The MDX Kelly Valve is also available with left-hand threads for use as an upper kelly cock. When used between the kelly and swivel, it provides a positive means for shutting off flow in the drill string at any time. The inline body design will not hang up on the cat line or interfere with operations.
                  Lower Kelly Valve:When used as a lower kelly cock, the MDX Kelly Valve provides a closure to stop mud loss when the kelly is disconnected from the drilling string. Just close the valve before disconnecting and mud in the kelly and hoses stays there. With the cost of oil mud, biopolymers and other costly drilling fluids, the valve can pay for itself quickly. The rig floor and substructure stays much cleaner and safer as well. Its streamlined O.D. allows it to pass through the blowout preventer smoothly.

                • Drilling stabilizerDrilling stabilizer

                    Drilling stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process. The types of it can be divided into drill string type and near bit type. At present,we developed HF3000 and HF4000 type stabilizer, which are widely used in international drilling operation. Drill collars, when used without stabilizers, tend to buckle and cause unwanted deviation. A typical bottom hole assembly (BHA) will include one or two stabilizers placed in the drill string to increase stiffness. Sometimes additional stabilizers are added to the drill string to further increase BHA rigidity to ensure that well bore deviation is minimized.
                    Stabilizers also prevent differential sticking of the drill string by stabilizing the BHA and keeping drill collars and drill pipe away from the borehole wall. This reduces vibration, drill pipe whirl, and well bore tortuosity; moreover, the stabilization maintains drilling trajectory whether drilling straight, horizontal, or directional wells.
                    Options for Stabilization
                    Our factory downhole offers stabilizers in straight and spiral orientation with two material options:
                    Alloy Steel Stabilizers non-Magnetic Stabilizers
                    The Integral Blade alloy Steel Stabilizer is a product of exact manufacturing and is engineered to stabilize your drill string in the most challenging drilling conditions. The rib surface shall be hard faced with HF4000 (Insert tungsten carbide buttons on the surface ) OR HF 3000( low temperature welding tungsten carbide pieces) .
                    When drilling through hard formations, the required weight on bit to drill the well bore exerts tremendous side loads on the blades of the stabilizer. The Integral Blade Stabilizer's one-piece construction ensures you have the reliability and durability to drill with confidence. MDX Downhole Integral Blade Stabilizers are available in both Straight and Spiral Blade designs.
                    Reduces vibration
                    Decreases drill pipe whirl
                    Reduces well bore tortuosity
                    The Non-Magnetic Stabilizers will centralize the drill string in all conditions, but are specifically engineered to be used in applications requiring magnetic isolation, making them ideal for directional drilling.
                    Features:The non-magnetic steel properties allow MWD tools to operate without interfering with the accuracy of their directional measurements. The non-magnetic stabilizers are compatible with other standard drill string components and are available in both spiral and straight blade configurations.
