What is the advantages of our drill pipe and drill rod?
- Good raw materials ,carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;
- A highly specialized heat treatment process and High precision tolerances
- Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these drilling rods, thereby helping the consumer save the cost.
