Derun Drill Pipe

Supplier: 304 stainless steel pipes, carbon steel pipes, galvanized steel pipes, seamless pipes, stainless steel pipes, used drill bits
Buyer: Used drill bits and drill pipes, tubing, casing

DERUN provides all type of drill pipes, include oil drill pipe, water well/geothermal well drill pipe, coalbed methane/shale gas drill pipe and flush joint drill pipe, also various kind of tool joints.

Derun drilling motor is a positive displacement motor. High pressure drilling fluid flows into the drilling motors, thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling. Derun produces LZ73, LZ89, LZ95, LZ102, LZ120, LZ127, LZ146, LZ165, LZ172, LZ185, LZ197, LZ203, LZ216, LZ244, LZ286 and other types of drilling motors. They are for drilling diameter of 88.9 to 660mm. Derun also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties. At present, in addition to ordinary straight drilling motors, Derun can also provide the following types of drilling motors: Bent drilling motors The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available. Bent angle adjustable drilling motors The bent angle of the drilling motors can be adjusted on well surface which enhance the extension of kicking off. Extension drilling motors On the basis of the ordinary drilling motor, improve motor torque to make the bit drilling quickly by increasing motor stage. Hollow drilling motors To meet the needs of high flow rate solids carrying in drilling, hollow rotors with carbide nozzles of different sizes are adopted, which can increase the input flow rate and the horsepower of drill bit. Drilling motors with high kick-off rate: Unique structural design, shorter body, bent point closer to the drill bit, and kick-off rate of up to 1 m. Saturated saltwater mud-resistant drilling motors: To maintain long time operation of drilling motors in saturated saltwater mud, special rotor coating is adopted to provide better corrosion and wear resistance. High temperature drilling motors In order to improve the high temperature resistance of the stator rubber of the drilling motors, to meet the drilling requirements in high geothermal gradient region and deep and ultra-deep well drilling requirements, high temperature resistant rubber is adopted to increase the temperature resistance of motor above 150 degree Sealed driving shaft drilling motors The ordinary mud lubricated driving shaft is replaced with oil lubricated seal driving shaft, which improves the working conditions of the thrust and radial bearings, thus extending the service life of the drilling motors.

Derun non-magnetic drill collars are made from non-magnetic materials with low-magnetic permeability. Api monogram, serial number, od, id, type and size of connections are stamped on recessed mill flats.

Derun mechanical drilling jar is a full mechanical drilling jar, it also can be use as fishing tool. It generates upward jarring as well as downward jarring which can solve tight pull or sticking troubles during drilling. It is the first optional drilling jar for vertical well, deep well, directional well and complicated well operations

d we get the right to use the api 5d logo. Material: stainless steel. Quality: drill pipe requires cutting edge equipment. Our drill pipe product line is completely automated with equipment from germany & the u.S., such as the friction weld machine, hardbending weld machine, ipsen furnace and siemans cnc lathe. The tool joints are made of aisi 4137h premium alloy steel fully q&t with the ipsen furnace. All the joints are inspected by florescence magnetic particle and the ultrasonic method. The pipe body goes under very serious inspection in conformance with api. 5d. The welding between the drill pipe an tool joint is accomplished with the friction welding machine, the welding process is swift & steady under computer control. The weld zone is quenched and tempered through the induction process which is computer controlled in real time. Packaged in bundle. Size: 9.5m x 3.5m x 5m. Weight: 5-25 mt
