Product Description


HDD Drill Pipe 6 5/8" , 7 5/8"

 

Technology highlights

 

After the scientific design of the thickening end and the accurate calculation of the thickening process, the advanced thickening equipment is used for thickening to ensure the long and smooth inner transition zone.

The multi-point temperature measuring natural gas walking furnace widely accepted by the oil drilling tool manufacturing industry is used to heat treat the pipe body to ensure the best fit of strength and toughness.

 

After long-term cooperation with international mainstream drilling companies, they fully understood their thread design concept and thread processing method, greatly improving their thread design ability.

QPQ method is used to treat the thread surface. The wear resistance and anti sticking level of the thread are leading in the world.

 

Quality control system 

 

The quality system is established according to API Q1. The professional quality system personnel have trained the whole staff for many times. Effective operation of quality system.

 

According to the requirements of API 5dp, 100% of drill pipe is subject to ultrasonic and magnetic flux leakage detection.

 

With all the required physical and chemical testing equipment, the drill pipe can be tested for all-round mechanical properties according to the requirements of API 5dp standard. All testing equipment is purchased from Mts.

 

Independent thread gauge storage room, 100% inspection of key thread parameters and keeping inspection records.

 

Raw material

Raw materials are from china top steel supplier Baosteel, the most advanced steel manufacturer in China.
