ROSCHEN always maintains certain advantages in technical equipment. There are two drill pipe production lines with an annual production capacity of 4000 tons. The main key equipment includes the intelligent full-automatic drill pipe intermediate frequency heat treatment production line. The equipment thread laser processor and 600t friction welding machine are welding machines with a diameter of 300 mm and a specification of J, 1000 ton thickening forging press, various intelligent CNC thread processing machines, wear-resistant automatic welding machine and other equipment.

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.

ROSCHEN management team declare "quality is the life of the enterprise, quality is the foundation of the brand", establishes a perfect drill pipe inspection center, and has all kinds of quality professionals and systematic inspection equipment. We has obtained ISO9001:2008, APIQ1 quality system certification.
