Drill Pipe 2 3/8''~6 5/8'' API 5DP Standard for Oil Well Downhole
Drilling
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 of the drill 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.
