drill pipe
Based on the comprehensive consideration of quality and cost, Teda Special Pipe Fittings Co., Ltd. has always insisted on providing drill pipes to meet various field needs to customers in the global oil field. Industry-leading design and processing equipment, experienced technical team, exquisite professional knowledge and strict quality control management system are important guarantees for the high quality performance of Teda drill pipe.
Characteristic:
Quality of raw materials
The physical properties of sulphur (< 0.003%) and phosphorus (< 0.015%) have reached the standard of high performance steel.
Extremely strong absorption energy
Absorption energy of drill pipe body and welding belt is much higher than API 5DP standard.
Traceability
Drill pipe fittings are made by welding the drill pipe joints to the tube body after thickening and heat treatment. The above important parts of the drill pipe have codes and records that can be traced.
Advanced Design
The transition zone of the thickening end is designed to be more smooth and extended according to the actual needs, so as to reduce stress concentration and prolong service life.
Accurate straightness
The eccentricity of the drill pipe body and the thickening end, the linearity of the pipe body and the joint, and the overall straightness of the drill pipe are much higher than the requirements of API 5DP.
