ULTRA HIGH STRENGTH STEELS
High Grades For Drill Pipe

VM-140 DP, VM-150 DP and VM-165 DP are proprietary drill pipe grades offered by VAM Drilling, which are developed specifically for harsh drilling conditions present in extended reach drilling (ERD), ultra-ERD, deepwater applications, ultra-deep wells, as well as high temperature high pressure (HPHT) environments. In addition, higher grades can enhance your hydraulic performances, by reducing the wall thickness compared to API grades.

Proprietary chemistries and controlled quench & tempering heat treatment allow high tensile and torsional strengths, associated with enhanced toughness properties, which can provide you higher safety margins in the current most challenging drilling environments.
