Fluid Grip Tong

For years running expensive corrosion resistant alloy tubulars without causing damaging die marks has been a problem. Traditional power tong gripping systems rely on metal toothed inserts which penetrate the pipe surface to obtain sufficient gripping force needed to generate torques required during make-up. These damaging indentions reduce wall thickness and create stress concentrations in localized areas which accelerate corrosion. Pipe body failures frequently occur in these areas.

 

FINALLY! A SOLUTION...

The search for a solution to this problem has been underway at Frank’s since the late 1960’s when Frank’s was granted its first U.S. patent for a dieless tong. The research and development continued and has led to the introduction of the new FLUID GRIP Power Tong.

 

The FLUID GRIP concept has completely revolutionized the approach to gripping tubulars by encircling it with fluid pressure. The gripping surface is completely non-metallic and does not alter the pipe surface in any way. When pressure is applied to the circumference of the tube body, it is done in a uniform manner regardless of the pipe’s degree of roundness or surface finish. Unlike other friction grip devices which have rigid jaw mechanisms the FLUID GRIP conforms to the pipe. The FLUID GRIP features an integral back up tong which utilizes the same gripping device as the power tong. The entire system is hydraulically controlled by the tong operator. Built in safe-guards prevent pressurization of the system while the tong is in the open position.
