HRQ series drill rods undergoes technical upgrading on the basis of Q drill rods. Well drilling capability is improved and well drilling cost is decreased due to its stable and reliable connection.
Pipe Body: Quality alloy steel pipe is adopted and 100% test is conducted for each raw material to ensure completely concentricity, straightness and heat treatment.
Thread: RQ thread drill rods adopt taper (3 threads per inch) connection and taper and reverse load angle are increased simultaneously to enhance connection strength and making up and breaking convenience.
Heat Treatment: The whole undergoes heat treatment process to improve service life of rods. Threads at both ends of the product undergo special process treatment on the basis of Q series product to improve about 175% of material strength to further improve strength of material. Service life of inner thread improves obviously.
Thread Surface Hardening: after special process treatment, outer thread surface hardness is up to about 60HRC, which further improves service life of the product;
Good RQ thread product series provides high performance, strength and quality assurance for wireline coring, enjoying wide application.
