OD 102mm Well Drilling Rods API 3 1/2'' REG Thread DTH Drill Pipe with 65mm Wrench Flat
Product Description:
DTH drill rods (also called as drill tubes or drill pipes) are the mechanism to transmit impact force and rotation torque to DTH hammers and bits, as well as offer pass for the air flow. In principle, the lighter the rod is, the better it is for the drilling operation. So a thinner one is always preferable than a thicker one if other parameters were the same. While in the mean time, the yield strength and the tensile strength must also be taken into accounts, which means relatively rod wall thickness would be needed to obtain enough strength. Of course, once the thickness is rigidly requested as thin as possible to minimize the drill string weight, there is also another method to get optimum drill tubes that using better grade steels.
Our down the hole drill pipe is manufactured based on the API standards. And according to specific requirements, we also provide this kind of DTH drill pipe in different Chinese and American specifications.
As for its advantages, it has features of big rigidity, good sealing capacity, flat outer structure, and low torque and resistance when rotating.
As to the packaging, a bundle of DTH drill pipes will be packed by one set of steel frame, and a bundle will have 30 to 40 drill pipes.
