Sinker bar is a steel rod of a specified length, normally in a larger diameter than sucker rods, is provided in standard sizes with externally threaded ends offered to add weight and stability to the sucker rod string. 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 a thread protector is 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.
