BUTTING was recently commissioned by a renowned customer to manufacture casings for a new geothermal project: 2,656 m of 273.1 × 10.16 mm casings made of Superduplex as well as 823 m of 339.7 × 12.19 mm casings made of Alloy 625, in production lengths between 30 ft (approx. 9.15 m) and 38 ft. (approx. 11.6 m) in each case.
BUTTING has been a reliable partner for casings used in geothermal drilling in the Salton Sea in Southern California for many years. These pipes are used to line boreholes. In this region, special challenges have to be mastered: high temperatures, heavy corrosion and difficult drilling.
