SLD 5 1/2 hydraulic power tong with micro tooth marks and no tooth marks

The SLD 5 1/2 hydraulic power tong is an open hydraulic power tong suitable for testing and well repair operations in oil and gas fields, marine oil fields, and for loading and unloading 2 3/8 "to 4 1/2" oil pipes and 4 1/2 "to 5 1/2" casing. This specification of power clamp is redesigned and improved based on the advantages of similar foreign products. The main clamp adopts a special structure clamp head, and the back clamp adopts a dual oil cylinder clamping structure, with a large clamping area and stable clamping performance.

Characteristics：

The clamp head structure is open-type, which allows quick and convenient entry and exit from the working position, and the integral clamp head has good strength stiffness.

Swinging double-jaw plate tong head, extremely convenient to install and remove, with the best cutting diameter ratio design, ensures reliable clamping and easy unloading;

Band brake, large braking torque, simple operation, easy to repair and replace

The open large gear support structure greatly improves the strength and stiffness of the open large gear.

 Fully hydraulic, using mechanical shifting, with simple and reliable structure;

The shell uses alloy steel plates, increasing the strength. Each jaw plate uses precision casting technology, with beautiful appearance and high strength;

The back vise uses double cylinder hydraulic clamping, which ensures reliable clamping performance and minimizes damage to the surface of the tubing

To be used along with Torque and rotational speed test system and Double pump hydraulic power station can precisely control the make up torque and rotation speed,it can display、control、storage、print torque parameters and etc.,and it can apply to the make up of FOX、VAM TOP、BGT1、3SB、NSCC、WSP type of tubing and casing.
