API Thread Drill Pipe Rod Matched Up with High Air Pressure Drill Rig-- We're doing pretty well! 1. Standard API thread forming and orientating processed at one step, which is our technical highlight. 2. Hardness and wear resistance combined alloy steel, supplied by national top-level special-steel manufacturer.(Pipe thickness and material can be user's choice) 3. Not all friction welding is strong, after a specialized friction welding process, welding outcome can be ensured. 4. Pipe curvature correction is a must process for each drill pipe. 5. Each processing step is stringently controlled, all Rarcs are CNC machined. 6. Premium alloy steel made joints strictly controlled heat treatment process and standard API thread processing technology; we pay high attention to all these easily ignored details to ensure pipe stability and thread durability.
