Product Description

Product Description

JX Petro Sinker Bars are manufactured from special quality hot rolled carbon manganese steel bars. Sinker bar dimensions and tolerances conform to API Spec. 11B, latest edition and AISI steel products manual. Sinker bars have a reduced section on one end for elevator seating and lifting. Pin blanks are machined and dimensions gauged. Pin threads are rolled cold-formed to strengthen the thread from fatigue. An inhibitor lubricant is applied to each pin and thread protector installed. An oil soluble coating protects sinker bars from atmospheric corrosion in storage. Sinker bars are bundled to prevent handling damage during transportation.
Special sizes and materials are available upon request.


JX Petro sinker bars with several combinations of body diameter and pin size. Some of these combinations are furnished with a Sucker Rod pin and others come with a Polished Rod pin. The table below lists each size of sinker bar. 

 

Sinker bars provide extra weight on the rod string to help keep the rod string straight, and in tension. If no sinker bars are present on the bottom of the rod string in deep, deviated, or big bore pumps, the rods will buckle, bend, and go into compression, causing rod parting and pump failure. sinker bars can Increase production by keeping the rods in tension and making the total rod stretch decrease, which allows the pump to be more efficient.
