地質勘探鉆桿/ Geological exploration drill

地質勘探鉆杄是用于煤礦探水、探瓦斯及地質勘探用鉆孔施工工具。我公司生產的地質勘探鉆杄，又稱仿英鉆杄、圓鉆杄、外平鉆杄、地質合金鉆杄和煤礦坑道常規鉆杄，包含石油鉆探用直徑89mm以下的勘探鉆桿和礦山鑿巖開采用潛孔鉆杄。鉆杄杄體選用優質地質專用合金鋼管，鉆杄接頭選用優質合金結構鋼，經真空調質處理，大大提高了抗疲勞強度和抗剪切強度。采用先進的摩擦焊焊接工藝生產加工，鉆桿具有抗彎強度高，焊接牢固等特點。生產設備完全采用先進的數控加工設備，具有生產效率高質量穩定的特點。能夠保證深孔鉆進時對直線度的要求，該產品具有較高的抗疲勞強度和較長的使用壽命。

Geological exploration and drill pipe is used in coal mine ground water, gas and geological exploration drilling construction tools. Geological exploration drill pipe made in our company, also called imitation of hen drill pipe outside flat, round drill pipe, drill pipe, geological alloy pipe and coal tunnel conventional drillpipe, contains oil drilling drill pipe with a diameter of 89 mm below the exploration and mining drilling with DIH dril pipe. Special geological drill rod body selection of quality alloy steel, alloy structural steel tool joint selection of quality by true air conditioning process, greatly improving the fatigue strength and the shear strength. Advanced friction welding welding technology production and processing, drill pipe hashigh bending strength, welding firm, etc. Production equipment complete advanced CNC processing equipment, has the characteristics of high efficiency stable quality. To meet the requirements of deep hole drilling on straightness, the product has high fatigue strength and longer service life.
