At current, the foreign production of Power drill pipe tongs international locations are the main American, the former Soviet Union and Canada and other international locations. America primarily Ecker (ECKEL), hydraulic power tongs sequence merchandise; Wacker (VARCO) company’s TW a 60 iron roughneck and SSW Pipe spinner series products; Hillman Kelly (HILLMAN KELLEY), PDP a 7250 type of Power tongs. The former Soviet Union is mainly Ural heavy machinery plant of AKB 3M2 tongs, a pneumatic on BK sort three, BK type four on a pneumatic Pipe spinner and Canadian FARR firm robust hydraulic motor forceps and many others..
From a variety of specifications and manufacturing state of affairs, expertise growth degree of American is still within the main place. The corporate’s full product specs eikner, with hydraulic power tongs is extra superior, is a sort of hydraulic power, double pace motor and double pace mechanical transmission is an open type Energy tongs transmission system, the clamping mechanism adopts a cam clamping system. The facility tongs is geared up with superior pc control system, can automatically measure torque, every connecting pipe reaches a predetermined torque can routinely cease when the tongs operation, is conducive to the safety of drill pipe joint. However this Pipe spinner liquid path is extra advanced, the load and the volume is bigger, the worth is costly (hydraulic energy tongs is priced at $75000, the pc torque management system for $35000). American Varco firm Pipe spinner with four roller urgent drill pipe body, by the friction force between the roller and the rotating drill pipe drilling rod. Pipe spinner makes use of several aerodynamic torque in low, typically threaded rotating not to shoulder, but the clamping mechanism clamps the drill pipe body, excessive efficiency, time average spinner per 21.Four s (Pipe spinner and Tong closely time and), which. Pipe spinner accounts for under 5 ~ 6 S, spinning rope and Tong spinner round twice as quick as the drill using ratio. Pipe spinner relies on four roller roller friction transmission energy, subsequently, to drive the fabric and course of selection is essential, roller, Varco firm has accomplished petroleum gel totally different friction driven spinner gadget to test drill pipe harm, the test outcomes present that: the chain and belt sort Pipe spinner produces tension and make contact with wear.
