VAM Drilling provides a complete line of drillstring products, including a full range of jointed drill pipe in nominal sizes from 2-3/8 to 6-5/8 and in a wide range of wall thicknesses.

VAM Drilling drill pipe is designed to provide superior technical performance and a service life time exceeding most current industry standards. VAM Drilling drill pipe is available with:

Proprietary oversized minimum internal upset (miu), where applicable; Longer tool joints, providing a maximum re-cut capability for longer service life; and Higher toughness specification on pipe body, weld and tool joint, providing greater safety margins in extreme drilling conditions.

VAM Drilling drill pipe meets or exceeds API specifications to satisfy the most stringent drilling conditions.

VAM Drilling tool joints meet or exceed API specifications and tolerance requirements. Each joint is inspected to monitor visual and dimensional properties, and tested to ensure the proper mechanical characteristics. All VAM Drilling tool joints are:

100 percent thread-gauged; 100 percent magnetic-particle inspected; Phos-coated (anti-galling treatment); and Hardness-tested.

One of the more critical sections in welded drill pipe is the transition zone between the tool joint and the pipe body. A smooth, gradual transition ensures the minimum stress concentration and greatly improves the fatigue life of the pipe.
