Unitesteel Drilling provides a complete line of drill string 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.
Unitesteel Drilling drill pipe is designed to provide superior technical performance and a service lifetime exceeding most current industry standards. Unitesteel Drilling drill pipe is available with:
- Proprietary oversized minimum internal upset (miu), for better fatigue resistance (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.
Unitesteel Drilling tool joint forgings meet or exceed API specifications and tolerance requirements. Each joint is inspected to guarantee visual and dimensional properties, and tested to ensure proper mechanical characteristics. All Unitesteel Drilling tool joint forgings are:
- 100% thread-gauged;
- 100% magnetic-particle inspected;
- Phos-coated (anti-galling treatment); and
- Hardness-tested.
Do not hesitate to contact our sales representatives with special needs to evaluate feasibility.
One of the most critical sections in welded drill pipe is the transition zone between the tool joint and the pipe body. A smooth, gradual transition linked to the superior nature of the purity of our steel ensures minimum stress concentration and greatly improves the fatigue life of the pipe.
