Sunrise Petro: A Pioneer in Sinker Bar Manufacturing in China

Sunrise petro owns a strong ability about research, design and production of sinker bar with decades of manufacturing experience. Sunrise has been certified by ISO9001, API Q1, ISO14001.Sunrise adopts the principle of combining API standards, national standards and user  views for design.

Sinker bars of Sunrise are exported to the United States, Canada, Europe, Africa and Middle East, and we establish cooperative relationships with international customers all over the world.

Description

Sinker Bar is heavier than the conventional rod. It is used at the bottom of the sucker rod string to keep the rod string under tension and reduce crooks of the sucker rod string during downward travel. Sinker bars provide concentrated weight above the pump to help keep the rod string straight and in tension, which reduces buckling of the sucker rods or the pump plunger. Sinker bars are made of hot rolled carbon manganese steel bar. Sinker bars are surface turned and have API double sucker rod pins, shoulders, and wrench flats on both ends. One end has a reduced section for elevator seating and lifting.

Grade and material

The current edition of API Specification 11B recognizes two grades of sinker bars, Grade 1 Carbon steel and Grade 2 Alloy steel.

Below are the material examples.

1. AISI 1024 Plain Carbon Steel 65,000 psi minimum tensile
2. AISI 4623 Nickel-Molybdenum Alloy Steel 90,000 psi minimum tensile.

In general, API Grade 1 is referred to as Grade C while API Grade 2 is referred to as Grade K depending on material alloy type.

Data sheet

The following is the data sheet of common sizes and mechanical properties of sinker bar.
