API Drill Pipe
Advantages:
Based on the first generation of DT-S 95, DT-S 105 anti-sulfur
drill pipes for use in moderate H2S corrosion environment,we have
developed the second-generation anti drill pipe DT-SS 75,DT-SS
95,DT-SS 105 used in severe H2S corrosion environment by optimizing
materials chemical composition and heat treatment
technologt.Performance index of SS series anti-sulfur drill pipe
are in line with IRP1.8,NACE MR0175 and ISO15156 and other
standards.
Specification:
Size:Cobers API standard all spectifications from 2-3/8"-6-5/8"
Steel grade: DT-SS 75,DT-SS 95,DT-SS 105
