Drive Rods and Pony Rods are manufactured from micro-alloyed, modified special quality hot rolled carbon or alloy steel. Bar and sucker rod dimensions and tolerances conform to API Spec 11B, latest edition, and AISI Steel Products Manual. It is used to connect the pumping unit on the ground and PCP. Sucker rod is an important part in the oil production system. Different grades of sucker rod has features of high strength, non-corrosive medium, good tensile and long service life.
Sucker Rods, Drive Rods and Pony Rods are manufactured from micro-alloyed, modified special quality hot rolled carbon or alloy steel. Bar and sucker rod dimensions and tolerances conform to API Spec 11B, latest edition, and AISI Steel Products Manual.
Sucker rods are available in 5/8" (15.88 mm), 3/4" (19.05 mm), 7/8" (22.23 mm), 1" (25.40 mm) and 1 1/8" (28.58 mm).
Drive Rods for Progressing Cavity Pump application are available in 1" (25.40 mm), 1 1/4" (31.75 mm), and 1 1/2" (38.10 mm) body diameter and in 25' (7.62 m) lengths.
1. All rods are straightened and inspected by Eddy Current/magnetic for surface defects.
2. Both ends are upset by automatic high-speed hot forging. Rods are full length normalized to relieve residual stresses, air-quenched, and tempered to refine and homogenize grain structure, and surface nor peened to remove any remaining heat treat scale.
3. All rods are also nor peened to improve fatigue life. Upset pin blanks are machined and dimensions gauged. Pin threads are cold-formed to strengthen the thread from fatigue.
4. An inhibitor-lubricant is applied to each pin and thread protector installed.
5. An oil soluble coating protects rods from atmospheric corrosion in storage.
6. All rods are bundled to prevent handling damage duringtransportation to the well location.
7. Quality control inspections are performed at each step of the manufacturing process.
