Polished Rod Clamps Used in Oilfield Applications

We are capable of producing single bolt polished rod clamp, double bolts polished rod clamp, as well as three bolts polished rod clamp. This can help us to meet customers’ special demand as the working load of our API polished rod clamp is largely improved.

Polished rod clamps can be classified as single bolt polished rod clamp, double bolts polished rod clamp and three bolts polished rod clamp according to the number of bolts.

Overview

All Skinner Clamps are forged from high-grade, heat treated steel. Bolts are cadmium plated. Hinge pins are 4140 heat treated steel.



The clamping surface of each Skinner clamp is bored and reamed to the exact size of the polished rod. Additionally, both ends are machine-squared with the hole to prevent eccentric loading if the hanger bar is flat.



The Skinner clamp exerts a 2:1 mechanical advantage in the ratio of distance from the center of the rod to the center of the bolt and from the center of the rod to the center of the pin. Contact areas are spaced to give maximum clamping effect.
