Products Advantages
High strength mechanical properties
Special smelting engineering design is selected for joint and tube body with special chemical composition and strict control of manufacturing process.
Long service life
All threads and sealing surfaces shall be phosphated to prevent sticking and corrosion.
The wear-resistant belt and pad of the joint can prolong service life.
Production equipments imported from germany
Each heat treatment welding zone is quenched and tempered by heat treatment system to ensure the strength and toughness of the welding zone and the quality is stable.
Drill pipe quality control
1. Before order to be confirmed, the raw material of pipe body and tool joint should be booked from famous big steel enterprises in China.
2. Raw material’s size, quantity, length, mechanical property are checked by our QC staff and factory own laboratory.
3. Every drill pipe has nondestructive inspection , cleaned and thread oil before packing.
4. Before delivery clients could send one QC or point the third party to check the quality such SGS, BV or others.
Advanced manufacturing technology
The drill rods adopt advanced thread manufacturing technology and advanced surface treatment technology, and are manufactured according to precise tolerances.
They have the characteristics of tight connection, good energy transmission effect, strong wear resistance and easy disassembly.
