API 7-1 Drill Pipe

Drill Pipe

Tiptop has full production process to perform pipe end upsetting, heat treatment, friction welding and threading. Our production capacity of drill pipe with API Standard, Non API Standard and special connections is about 20,000MT per year.

Green Pipe

Seamless green pipe is made from high grade chrome-molybdenum steel. Ends of pipes are upset twice with smooth to reduce damage to property of pipe body. Our drill pipe product has good fatigue endurance performance and long working life.

Key Process Control

Friction Welding

We have two sets of heavy duty friction welders. These two welders can optimize parameter of welding by automatic memory of previous parameters to improve the quality of welding lines.

Heat Treatment

Our induction machine can automatically adjust temperature, heating time, wind cooling time in order to have a better mechanical property and stable metallography in weld zone.

Quality Inspection

All the data of procedure of inspection and final inspection are recorded by ERP online to ensure the traceability. 100% of samples are tested through visual inspection, hardness testing, magnetic particle inspection and ultrasonic inspection to ensure the quality of each batch of drill pipe.
