Description:
The HDD drill rod has four different specifications for customer's choice: 50, 60, 73 and 89. And the length of drill rods and connection threads can be made totally according to specific requirements of clients. The normal length of our HDD drill rods is 3m.
Regarding its packaging, slotted steel frameworks are utilized to pack HDD drill rods in the forms of bundle, and each bundle has 20 to 50 drill rods.
Features of HDD Drill Rods:
1.Pipe end upsetting technology, self connecting mode and heat treatment have been used in the manufacture of this kind of HDD drill rod. Thus, our drill rods in different specifications possess excellent mechanical properties.
2.Double-step structure is used for its male and female threads, so this kind of drill rod has optimal sealing property and after torsion, there is little transformation in the rod.
3.Chemical plating (electroless plating) is used on the surfaces of threads so as to improve the hardness of surface and abrasive resistance of thread.
4.Our HDD drill rods can work together with various horizontal directional drill rigs within and beyond China.
Horizontal directional drilling rig I.Product description The horizontal directional drilling rig(hdd)is a kind of construction Machinery which can lay a variety of underground utilities (pipes, cables, etc.) without excavating the surface of the ground. Horizontal directional drilling technology is a new construction technology which combines the directional drilling technology to the oil industry and the traditional method of pipeline construction together. I.Used in the field of: 1.Water supply pipeline construction project 2.Electric power pipeline construction project 3.Telecommunication pipeline construction project 4.Natural gas pipeline construction project 5.Coal gas pipeline construction project 6.Oil pipeline construction project 7.Sewage pipeline construction project Ground conditions: sand clay, pebbles and other ground conditions. Ii.Features 1) lowest diesel fuel consumption.(cummins engine) 2) main components all adopt famous products from home and abroad. 3) powerful diesel engine, low noise, suitable for construction in downtown. 4) the power head is equipped with two engine; stable torque. 5) push/pull system is driven by double engine;fast and snow level, can move fast. 6) easy to control;ball valve can lead to fast/snow level;more safe to tow and can walk at a high speed. 7) mud pump is driven by hydraulic pressure; speed-changing flexibly according to different geological conditions and construction technology. 8) use long drill, main body moderately take the efficiency and construction requirements in narrow place into account. 9) hydraulic pressure leg can adjust machine more stable and convenient.
