VAM DRILLING STEEL GRADES
High Strength And Performance

VAM Drilling has inherited of Vallourec & Mannesmann strong experience in steel developments.

Taking advantage of Vallourec & Mannesmann Tubes leading position in the Oil & Gas market for premium products, VAM Drilling is increasingly supplying top-of-the-range grades such as VM-150 and VM-105 DP SS to meet the performance and economic demands associated with increasingly harsh drilling conditions.

All standard API grades (E-75, X-95, G-105, S-135) and all proprietary Sour Service grades, such as
VM-95 DP SS and VM-105 DP SS, are manufactured in Range 2 and Range 3 lengths and are available in the full range of pipe sizes meeting the most stringent service requirements of clients.
