Manual Tong
Manual Tongs are necessary tools applied to make up and break out pipes. Changing lug jaws and latch steps can adjust different handling sizes of the tongs. They are completely interchangeable with other major manufacturer's tongs (Varco BJ, Woolley, and National Oilwell Varco). Each tong features tough, heavy -duty designs with heat-treated hinge pins and long-lasting "stagger tooth" tong dies (Blue Diamond, Pyramid). They are designed and manufactured according to API Spec 7K.
