In geological exploration work, the role of drill pipe cannot be underestimated, through which special operations such as applying drilling pressure, transmitting power, conveying drilling fluid, squeezing cement and dealing with downhole accidents can be carried out. With the advantages of fast drilling speed, long life of diamond bit, high time utilization and low labor intensity of workers, core drilling rods are widely used in geological exploration and coalfield exploration.

Core drilling rods have many advantages, such as controlling hole deflection, improving drilling efficiency, reducing project cost, increasing coring rate and reducing in-hole accidents. There are so many brands of drill pipes in the market that you need to do your homework and choose the right one. For this reason, we introduce to you the following guidelines for the purchase of core drilling rods.

1. The material of the drill pipe is crucial to the quality of the drill pipe. Ordinary drill pipes are not enough to withstand the high pressure and high impact force generated during the drilling process and are prone to fracture and failure and short service life, but the rope coring drill pipes produced by AUPROSPECT are free from such worries because the main body of our drill pipes is made of geological special alloy steel tubes and the drill bits are made of high quality alloy structural steel. Our drill pipes have high bending strength and strong weldability, which can guarantee the straightness required for deep hole drilling. The performance is more stable and the service life is longer.

2. Good coring drill pipes have high requirements on production and processing technology. The quality of core drilling rods mainly depends on the choice of materials and the strength of the threads at the rod ends.AU series rods are commonly used in the international geological exploration industry. With tapered thread connection, the connection is easy and prevents seizure, and the thread surface is hardened to greatly extend the life of the thread. Our RAU series products are technically upgraded on the basis of AU products, which improve drilling capacity and reduce drilling cost due to their stable and reliable connections.

3. Core drilling rods are upsetting by both ends. It is used in the field of geological exploration to transfer the drilling rig torque to the bit at the bottom of the well and is responsible for transferring the drilling fluid to the drilling tool. Traditionally, geological drill pipes are divided into two types: inner thickened drill pipes and outer thickened drill pipes, usually Φ60 and below diameters are inner thickened and Φ60 and above diameters are outer thickened. Drill pipes of different lengths and specifications have different drilling depths and working strengths, so we have to choose according to our actual needs.

4、The manufacturer has strong comprehensive strength, more sophisticated equipment, more exquisite technology, more considerate service and better product quality performance. AUPROSPECT specializes in drilling tools in the field of R7D drilling technology, manufacturing all downhole tools, serving the drilling industry and its accessories. We are your reliable choice.
