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.
Strict process testing
100% of the friction welding areas pass the ultrasonic and magnetic particle inspection, and the hardness test is carried out in the heat affected zone.
Application
Tunnelling, Mining, Quarrying, Blasting and Infrastructure Construction
Facedrilling and Bolting, Bench Drilling, Production drilling, Long hole drilling
Drill pipe quality control:
1. Before order to be confirmed, the raw material of pipe and tool joint body should be booked from famous big steel enterprises in China.
2. Checked by our QC staff and factory own laboratory.
3. Every drill pipe has nondestructive inspection , cleaned and breach 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.
