Down th hole drill pipes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability. Sinodrills DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe.The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.
Standard DTH drill pipe:
Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm,
Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;
Thread: 2 3/8 API REG, 2 7/8 API REG, 3 1/2 API REG, 4 1/2 API REG, 2 3/8 API IF, 3 1/2 API IF
Special DTH drill pipe:
The drill pipe for Atlas Copco Ingersol Rand T4, Schramm T64, Atlas Copco F6, L6 and L8, and the drill pipe for Sandvik Driltech D25/D40K.
The Spiral Drill Collar of Lake is made from AISI 4145H modified alloy steel, and completely meets the requirement of API Spec 7-1 and SY/T5144 Standard. It is a kind of drill collar which adds three dextrogyrate spiral groove on the outer circle of ordinary drill collar when processing, and the purpose is to reduce the area of contact and friction with the well wall, which can effectively prevent the pressure sticking. The single weight of the spiral drill collar is round about 4% lighter than the ordinary drill collar with the same specification, and the shape and thread of the both ends are the same with the drill collar.
Cemented Tungsten Carbide Oilfield Fittings are widely used in mining and quarrying and cutting process, also may be placed on a heavy excavators used in bit due to its high hardness of the cemented carbide and other characteristics
Cemented Tungsten carbide is a hard material composed of a metal matrix composite where carbide particles act as the aggregate and a metallic binder serves as the matrix. It is one of the most successful composite engineering materials ever produced. Its unique combination of strength, hardness and toughness satisfies the most demanding applications.
There has been a rapid development in tungsten carbide mining and stone cutting tools, with improved performance which has led to the increasing substitution of steel tools by cemented carbide tools, in particular in the oil industry. Notably, the use of very coarse grained hardmetals is growing in this application area.

Type b stands for reduce type: one crossover sub has two sizes.
Type c for left hand thread type: the connection thread is left hand type.
Use:
it plays a role of connectivity and conversion in different specifications drilling tools.
Characters:
crossover subs are complied with SY5200-93 or API Spec7. All products must be ultrasonic nondestructive tested and the surface copper coated. Crossover subs of various types and lengths are available.

Traceability:
Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies.
Rigid Inspection Procedures:
We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar.
Cold Rolling:
Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation.
Phosphate-coated or Copper Plating:
All connections are phosphate-coated or copper plated to improve resistance to corrosion.
Slip Groove, Elevator Groove and Size:
Lake offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines.
Thread Protectors:
Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.
Downhole motor is a kind of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters.
ADVANTAGES OF DOWNHOLE MOTOR
Increased rate of penetration.
Better hole deviation control.
Reduction in drill string failure rate.
Reduction in wear and tear of the swivel, Kelly, and rotary drives.
Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.
