-
TQ series of casing tongs are widely
used for making up and breaking out pipes or casings in
diameters of 4″-13 3/8″.
-
The tong heads are designed “open”
type and can freely clamp and escape from the casing. It is
safe, reliable and easy to handle with high mobility.
-
TQ casing tangs can be connected to
computer controlling units and can serve as ideal well
mechanical tools for surface operation.
-
The tong is designed and
manufactured according to API 7K specification for drilling
equipment.
