Product Structure and Working Principle
The DB Manual Tong uses a tong body, latch lug jaw, hinge pin, latch step and handle structure to grip oilfield tubulars and transfer torque. Before operation, the crew selects the correct latch lug jaw and hinge pin hole according to the pipe outside diameter.
During make-up operations, the tong grips the pipe and helps tighten the threaded connection. During break-out operations, it helps loosen the connection so the crew can separate the pipe string, casing joint, tubing section or downhole tool.
This simple working principle gives operators direct control on the rig floor. It also makes inspection and maintenance easier in field environments where mud, oil, vibration and frequent pipe movement are common.
Advantages for Oilfield Contractors
The SGPE Q 3.1/2~17-90 DB Manual Tong helps drilling and workover crews improve daily rig floor efficiency. One tong body can cover tubulars from 3-1/2 inch to 17 inch through different jaw and hinge pin configurations, so contractors can reduce tool inventory and improve field flexibility.
With the correct jaw configuration, the tong grips the pipe firmly and helps reduce slipping during make-up and break-out work. This stable grip supports smoother torque application and helps crews handle threaded connections more confidently.
The manual structure also simplifies inspection and maintenance. Rig crews can check the tong body, jaws, pins and latch components during routine checks, which helps reduce downtime and keeps the tool ready for field service.
In addition, the API Spec 7K design gives buyers more confidence when sourcing manual tongs for professional drilling, workover and well service projects.
