1.We adopts famous domestic large steel enterprises(such as Anshan Iron and Steel Group corporation and Hengyang Steel Group) production of material to produce drill pipe, and heat treatment of materials by using an integrated multi-processing furnace, professional CNC machining was applied in all of the connection thread processing, all the threads are configured thread gauge, which are in accordance with international standard, Internal thickening technology has carrued on the tempering process after friction welding, so the processing quality of drill pipe is stable, reliable, use cycle greatly extended. We can process different length, diameter and wall thickness and material of API standard thread rod, we also can design and manufacture drill pipe according to customers' requirement of the material, length, wall thicknessa and connection thread.
2.Our drill rods are of the highest quality ,are manufactured to exacting specifications using advancing maching technoogy.
3.They are manufactured from seamless steel tube by cold drawn.The materialwhich meets the global standard.
4. Drill rods are made from quality heat treated materials which ensure superior strength, wear resistance and toughness in the most demanding applications
5. Rods and casing are manufactured under stringent industry standards, and are field tested under a variety of conditions.
Advantages of API Standard Drill Rods:
1.applicable hard,very hard and medium soft rock formations.
2.Reliable quality, long service life, rare abnormal breakage during service life.
3.Good flushing effect to ensure high drilling rate
4.Strict quality warranty and compensation rules
