Product DescriptionProduct Introduction The geological drilling rod is made of geological alloy steel pipes that are friction welded, high-pressure treated, and refined.Drill rods have the characteristics of good strength, high bending strength, and firm welding, which can ensure the requirementsfor straightness during deep hole drilling. This product has high fatigue resistance and a long service lifeCommon specifications of geological drilling rodsΦ34*1m,Φ42*1m,Φ50*1m,Φ60*1m,Φ63.5*1m,Φ73*1mCommon connection methods for geological drilling rodsMale female connection (tapered thread), joint connection (rectangular internal thread)Geological drilling rod materialThe geological drilling rod body is made of geological special alloy steel pipes (R780, DZ50), and the geological drilling roddrill bit is made of high-quality alloy structural steel (42CrMo) that has been vacuum quenched and tempered, greatly improvingits fatigue strength and shear strength.Other productsIn addition to producing oil drill rods, our tubing&casing couplings, short joints, and pipe reducers have also received good feedback in the market!
