Introduction
Adapter fittings/connectors are made of 35CrMo or 42CrMo round steel. Heat treatment after rough machining. After finishing, the surface is nitrided, which effectively eliminates the failure probability of seizing, breaking and outer diameter cracking. It is more wear-resistant and easy to disassemble.
Tips
1. New drill pipe tool joints should be coated with thread oil before connecting
2. Make at least 3 combinations and fractures before drilling
3. Hard bending and plastic coating can be processed according to the special requirements of customers
