Spiral-Wate drill pipe, spiraled heavy-wall drill pipe, is designed to handle maximum stress to save time and reduce drilling costs, especially in tough drilling environments. Intermediate drill string members are constantly subjected to some of the most severe tasks in drilling today. The critical transition zone between stiff, heavy drill collars (under compression) and the light, more flexible drill pipe (in tension) is critical to the performance of the drill string. Spiral-Wate drill pipe’s unique patented spiral design reduces differential sticking problems, minimizes wear and improves circulation. Precision tool joint alignment cuts down on excessive tool joint wear for longer service life and reduced fatigue.
