• 7.”SDD” Tong covers drill pipe or casing sizes from 4″ through 17″ OD and is rugged in design and allows the operator greater torque when needed. The tong is made from alloy steel, heat treated and magnetic particle inspected, and complies to API 7K.
• 8.Manual Tongs Type LF are tools for unloading and unbuckling various types of pipe strings and tools during workover operations. By changing the buckle heads and buckling steps, it can meet the needs of different sizes of pipe diameters and unbuckling. Applicable pipe diameter: 2.3/8-7in; maximum torque: 48kN.m; products are designed and manufactured according to API Spec 7K specifications.
• 9.Workover manual Tong is a kind of tool used for make-up/break-out drilling tools and pipes during workover and drilling water well operation or other drilling operations. The workover manual tong consists of tong handle, long jaw, short jaw, latch, locking handle, dies, etc.; the utility model workover manual tong reduces the sectional area and size of original tong, and changes the tooth-form on dies into double-arc rhombic-like convex shape, and a locking piece is installed at the tail end of the workover manual tong to prevent the wireline from sliding out and balance the tong head.

This workover manual tong is compact, light, and easy to operate with strong latching performance, and it is an ideal tool for well services. andling size of this type tong can be adjusted by changing latch lug jaws.

Product maintenance:
