Sanjack oilfield rod clamp manufacturer according to the requirement of the customer can produce Sanjack no-dent polished rod clamp that the nominal diameter and dimension accuracy are not standard.

Sanjack polished rod is no dent, can effectively reduce the damage to the polished rod and the packing of the stuffing box.

If the viscosity of crude in the well is high, and the impact happens due to the downstroke lag of polished rod, Sanjack oilfield rod clamp manufacturer recommends changing a clamp of larger working load or use two clamps of the same model and same load to increase the working load.

Operation Manual of oil recovery tools–Polished Rod Clamp

1). The nominal diameter of polished rod rated center bore should be the same as that of matching polished rod clamp.

2). The rated working load for polished rod clamp should be more than or equal to the needed polished rod load.

3). Before using, clean polished rod inner bore and oil stains on polished rod surface to guarantee that the surface is bright and clean.

4). During installation, polished rod clamp lower end should be tightly close to pumping unit carrier bar to avoid impact when started.

5). If the viscosity of crude oil in the oil well is too big, polished rod lagging down and occurs impacting phenomenon, our suggestion is to change bigger working load or use two polished rod clamp in the same type, the same working load together to increase the working load. The two polished rod clamp ends should be closed tight when installation.

6). Two bolts should be fastened evenly for the two-bolt polished rod clamp.
