casing power tong
TQ series of casing power tongs are widely used to unload the threads of casing or pipe during casing operation in oil field. They have the advantages of lightweight structure, high efficiency and safe and reliable operation. They can greatly reduce the labor intensity of workers and improve the connection quality of pipe string threads. The clamp head is open type and adopts advanced swinging double jaw plate clamp to ensure reliable clamping. It can be equipped with a torque meter to monitor and manage the pressure, torque and number of cycles by computer. It conforms to SY/T5074 standard and API Spec 7K specification.
