Drilling Rod type:
QO series drilling rod is interchangeable with Q series coring drilling rod that is common in the international geological exploration industry. Taper threaded connection is adopted to facilitate connection and prevent stuck, and thread surface is hardened to greatly prolong service life of the thread.
Pipe body: Quality alloy steel pipe is adopted and 100% test is conducted for each raw material to ensure uniform concentricity, straightness and heat treatment.
Thread: Taper threaded connection (3 threads per inch) is adopted to facilitate connection and prevent thread stuck. Each thread is under relatively even stress, providing sufficient strength for product application.
Heat treatment: The whole undergoes heat treatment process to improve service life of products. Threads at both ends of the product undergo special process treatment to provide about 140% of material strength. Service life of inner thread improves obviously.
Thread surface hardening: after special process treatment, outer thread surface hardness is up to about 55HRC, which effectively avoids "sticking thread" and reduces abrasion and "stuck" due to engagement of thread;
RQO series product undergoes technical upgrading on the basis of QO product. 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 uniform concentricity, straightness and heat treatment.
Thread: RQO thread product adopts taper (3 threads per inch) connection and taper and reverse load angle are increased simultaneously to enhance connection strength and assembling and disassembling convenience.
Heat treatment: The whole undergoes heat treatment process to improve service life of products. Threads at both ends of the product undergo special process treatment on the basis of QO series product to improve about 175% of material strength to further improve strength of material. Service life of inner thread improves obviously.
