Circular Geological Drill Rod

Geological exploration Drill RodBody of alloy geological drill rod is made of high quality special alloy steel pipe that used in geology and drill rod joints is made of high quality alloy constructional steel. The drilling depth will depends on physical properties and parameters of the actual rod material while working in hard rock,Website:http://www.qianruidrill.com, coal or other special circumstances.Product Characteristics:Friction welding process is applied on geological alloy drill rod to guarantee the requirement for straightness as the deep drilling with the higher fatigue resistance and longer service life. Geological alloy drill rod composes of the special geological drill pipe and the matching joints by means of friction welding, therefore, geological alloy drill rod has the excellent mobility and higher tensile strength, which could be used to the regular drilling and firedamp drainage.Product Application:Geological alloy drill rod is used to the advanced detection of the working seam in coal mine industry, such as water detection and methane extraction drilling. Meantime, geological alloy drill rod has the high torque property same as that of outward flat geological drill rod, which enable to proceed the regular boring and construction in the rock gangway. Geological alloy drill rod is widely used in boring construction of drilling, anchoring and blasting of many industries, such as drilling and anchoring in petroleum, coal mine, metal ore extraction, railway and highway, tunnel and bridge, hydraulic engineering and so on.Technical Parameter:Itemmm  Specification MMProduction ProcessConnection MethodDiameterLongType of Thread1Ф34500～3000Tapered ThreadFriction WeldingBox-pin Connection2Ф42500～3000Tapered ThreadFriction WeldingBox-pin Connection3Ф50500～3000Tapered ThreadFriction WeldingBox-pin Connection4Ф63.5500～3000Tapered ThreadFriction WeldingBox-pin Connection5Ф73500～3000Tapered ThreadFriction WeldingBox-pin Connection6Ф89500～3000Tapered ThreadFriction WeldingBox-pin Connection7Ф35500～3000Rectangular Internal ThreadLathing Thread on BodyJoint Connection8Ф42500～3000Rectangular Internal ThreadLathing Thread on BodyJoint Connection9Ф50500～3000Rectangular Internal ThreadLathing Thread on BodyJoint Connection10Ф60500～3000Rectangular Internal ThreadLathing Thread on BodyJoint Connection
