1.外平钻杆 flat drill该型钻杆主要适应潜孔锤冲击回转（含液、气）钻进需要，具有刚性的，密封好，外平的结构特点，回转时扭矩低、阻力小优势。
The flat drill pipe is mainly appliable for the needs of Hydro-hammer percussive-rotary drill (liquid and gas),which is feathered by such advantages as high rigidity ,good airtightness,flat external structure,low rotary torsion and less resistance.
2.地质钻杆 geological drill pipe
适用于地质、水文、煤田、地热、工程钻探。
Geological drill pipe is applicable for geological,hydrographical,coal mining,terrestrial heat and engineeringdrilling.
3.非开挖钻杆 non-dig drill pipe
非开挖钻杆是用于在定向钻进施工中传递钻机扭矩与拉力的一种工具，由于它在定向施工中需要承受扭矩、拉力、弯曲、摩擦、震动，所以它的制作过程需要非常严格。
Non-dig drill pipe is a tool applicable for transfering torque and tension of drillers in the process of directional drilling construction.Due to the fact that
it has to bear torsion,tension,bending,friction and vibration in the process of directional construction ,the requirements for processing are very strict.
4.水井钻杆 water well drill pipe
应用于矿山爆破、水井钻孔，地热井钻孔，管棚支护，煤炭及有色金属采矿工程等径向成孔的钻孔工程。
Using to projects of mine blasting,water well drill ,geothermal well drill,pipe-shed support drilling,coal mining and non-ferrous mental mining and so on.
