GNY Casing Clamps for Drilling
GNY Casing Clamps for Drilling
Casing Clamps, a mechanical device designed to facilitate the hoisting or suspension of casing in a borehole. Clamps are made by forming a half circle in a heavy steel plates and bars.
The Company was an early pioneer in the development of hydrant type aircraft refueling equipment and related aircraft ground support equipment. Experience in this field led to the designing and manufacturing of Aviation, Oil and Gas Equipment. The company had traded under the name Garsite TSR.
The Deer Park facility remained in New York as Garsite International until in December 1995, when GNY Equipment, LLC (GNY) was spun-off to an independent status, bringing with it, almost a half-century of experience in aviation fueling, in liquid, air, oil and gas equipment. The people at GNY have been manufacturing fueling equipment for over three decades.
GNY Equipment, offers Casing Clamps, a mechanical device designed to facilitate the hoisting or suspension of casing in a borehole. Clamps are made by forming a half circle in a heavy steel plates and bars. When bolted tighter, in pairs, the bar fits around the outside and tightly grips the casing. The size of the clamp is determined by the outside diameter of the casing to be handled. Generally used for Drilling Operations.
