The 7-5/8" Casing Tong with the integral 8-5/8" Back-Up is the ideal casing tong for running casing and tubing from 7-5/8" down to 2-1/16"
For running tubulars with (high) chrome content OWS has fitted the Chrome Master Head on the 7-5/8" Casing tongs. With this Chrome Master Head OWS can ensure a full 360° wrap on the body of the tubular with limited indentation on both steel and coating.
The 7-5/8" Casing tong is an open-throat design that can handle tubulars from as small as 2-1/16" to as large as 7-5/8" in diameter. The system features two jaws in the tong and three jaws in the backup, which encircle the pipe. Wraparound jaws and dies, combined with our low-friction jaw technology, constant radial load cam system, and compensating jaw design, provide exceptional gripping capabilities with reduced pipe deformation, stress, and marking. Using our non-marking aluminum die system or GRIT FACE™ Dies in the tong and backup will allow stainless steel corrosion-resistant alloy (CRA) to be run as quickly and easily as traditional tongs run conventional steel tubulars.
The 7-5/8" Casing tong can be fitted with Chrome Master accessory upon clients request. With the Chrome Master the operator can manually operate and control the pressure intensifier system. This allows non-marking of thinwalled, low strength or expandable tubular goods.
