• Pump diameter
• Fluid density
• Well deviation
• Tubing condition
• H₂S and CO₂ concentration
• Chloride content
• Corrosion-inhibitor program

Standard Pin End

The standard API pin end consists of:

• Rod-body transition
• Forged upset
• Wrench square
• Pin shoulder
• Thread relief
• API sucker-rod pin thread
• Rounded stress-transition areas

The upset section increases the cross-sectional area around the connection and transfers cyclic load between the rod body, pin and coupling.

Reinforced Pin Sucker Rod

The Reinforced Pin configuration uses a larger pin connection on a smaller rod body.

Common configurations include:

• 3/4 in rod body with 7/8 in pin
• 7/8 in rod body with 1 in pin

Reinforced pins provide:

• Increased thread-root area
• Larger pin shoulder
• Increased connection load capacity
• Reduced connection stress concentration
• Improved fatigue performance
• Increased resistance to pin failure

Reinforced Pin Rods are used where the connection experiences greater cyclic stress than the central rod body.

API Sucker Rod Threads

The pin threads provide the mechanical connection between the Sucker Rod and coupling.

Thread quality controls include:

• Thread form
• Pitch diameter
• Lead
• Taper
• Crest and root profile
• Thread length
• Pin-shoulder position
• Shoulder perpendicularity
• Surface finish
• Gauge compliance

Pin threads are manufactured by precision machining or cold forming.

Cold-formed threads create a favorable grain-flow pattern and compressive surface stress around the thread root.

Rod Couplings

Goldenman supplies full-size and slim-hole couplings for all standard Sucker Rod sizes.

The coupling has:

• Two internal box threads
• Central wrench surface
• Controlled outside diameter
• Internal thread relief
• Corrosion-protective surface
• Permanent size and grade markings

Available coupling types include:

• API Class T Coupling
• Spray-Metal Coupling
• High-Strength Coupling
• Slim-Hole Coupling
• Polished-Rod Coupling
• Sub-Coupling
• PCP Coupling

API Class T Couplings

Class T Couplings are manufactured from heat-treated alloy steel.

Typical coupling dimensions include:

Rod Size	Coupling Outside Diameter	Coupling Length
5/8 in	38.1 mm	101.6 mm
3/4 in	41.3 mm	101.6 mm
7/8 in	46.0 mm	101.6 mm
1 in	55.6 mm	114.3 mm
1-1/8 in	Heavy-duty API configuration	API configuration

Class T Couplings are used in conventional rod strings with controlled tubing contact and corrosion conditions.

Spray-Metal Couplings

Spray-Metal Couplings have a wear-resistant metallic coating on the coupling outside diameter.

They provide:

• Reduced coupling-to-tubing wear
• Increased surface hardness
• Lower friction
• Improved corrosion resistance
• Reduced galling
• Extended coupling life in deviated wells

Spray-Metal Couplings are used in:

• Deviated wells
• Directional wells
• High side-load sections
• Wells with frequent rod-tubing contact
• High-cycle artificial-lift systems

Sucker Rod Guides

Rod Guides centralize the rod string inside the production tubing.

Available types include:

• Molded-on rod guides
• Snap-on guides
• Rotating rod guides
• High-temperature guides
• Abrasion-resistant polymer guides
• Chemical-resistant guides

Rod Guides reduce:

• Rod-to-tubing contact
• Tubing wear
• Coupling wear
• Rod-string vibration
• Buckling
• Localized corrosion

Guide spacing is based on well deviation, tubing diameter, rod size, side load and operating stroke.

Sinker Bars

Sinker Bars are heavy rod-string components installed near the downhole pump.

Their functions include:

• Maintaining rod-string tension
• Reducing lower-string buckling
• Supporting downstroke movement
• Stabilizing the pump connection
• Reducing compressive stress
• Improving rod-string alignment

Sinker Bars are supplied with API sucker-rod connections matching the selected rod string.

Full-Length Heat Treatment

Heat-treatment routes include:

• Normalizing
• Quenching and tempering
• Air quenching and tempering
• Stress relieving
• Grade-specific controlled cooling

Heat treatment controls:

• Yield strength
• Tensile strength
• Ductility
• Toughness
• Hardness
• Grain structure
• Residual stress
• Fatigue performance

The rod body and upset ends are processed to obtain consistent properties across the complete component.

Shot Peening

Shot peening creates compressive residual stress on the rod surface.

It improves resistance to fatigue cracks originating from:

• Surface scratches
• Handling damage
• Small corrosion pits
• Cyclic bending
• Rod-tubing contact
• Repeated tensile loading

Shot-peened rods are used in high-cycle and high-load artificial-lift systems.

Protective Coatings

Available surface systems include:

• Oil-soluble storage coating
• Corrosion-inhibiting coating
• Black oxide
• Phosphate coating
• Epoxy coating
• Polymer coating
• Project-specific corrosion-resistant coating

The coating protects the rod during:

• Storage
• Ocean transportation
• Outdoor handling
• Wellsite preparation
• Initial installation

Thread protectors remain installed until the rod is prepared for makeup.

Beam-Pumping Applications

In a beam-pumping system, the rod string transfers reciprocating motion from the surface Pumping Unit to the downhole Rod Pump.

The rod string experiences:

• Alternating tensile load
• Cyclic stress
• Fluid load
• Rod weight
• Dynamic acceleration
• Bending stress
• Rod-tubing contact
• Corrosion fatigue

Rod size and grade are selected using the complete load cycle rather than maximum static weight alone.

Progressive Cavity Pump Applications

In a PCP system, the rod string transfers rotation and torque from the surface drive to the downhole rotor.

The rods experience:

• Axial tension
• Continuous torque
• Torsional cycling
• Bending
• Rod-tubing contact
• Dynamic vibration
• Corrosion fatigue

D Alloy, D Special, KD and high-strength rods provide the strength and toughness required for combined axial and torsional loading.

Tapered Rod Strings

A tapered rod string uses larger-diameter rods near the surface and smaller rods toward the pump.

A typical string can include:

• 1 in rods in the upper section
• 7/8 in rods in the middle section
• 3/4 in rods in the lower section
• Pony Rods for final length adjustment

A tapered design reduces:

• Total rod-string weight
• Surface polished-rod load
• Stress concentration
• Energy consumption
• Unnecessary material cost

The taper program is selected from well depth, pump size, fluid load, stroke length and allowable stress.

Corrosion and Fatigue Control

Premature rod failure commonly results from the interaction of cyclic stress and corrosion.

The complete corrosion-control strategy includes:

• Correct rod grade
• Controlled material hardness
• Smooth rod-body surface
• Shot peening
• Corrosion-resistant coating
• Chemical inhibition
• Water-chemistry control
• Oxygen exclusion
• Correct rod-guide spacing
• Correct coupling makeup
• Regular failure analysis

A high-strength grade does not replace fluid-treatment and mechanical-load control.

Installation and Makeup

Installation procedure:

1. Verify rod size, grade and length.
2. Inspect the rod body and upset ends.
3. Remove thread protectors.
4. Clean the pin and coupling threads.
5. Inspect the pin shoulder.
6. Apply the specified thread lubricant.
7. Start the coupling by hand.
8. Use calibrated rod tongs.
9. Apply controlled makeup displacement or torque.
10. Avoid gripping the rod body.
11. Install rod guides according to the well program.
12. Record the rod sequence and Pony Rod positions.
13. Protect the polished-rod connection.
14. Complete the rod-string load check.

Under-makeup permits cyclic connection movement. Excessive makeup damages the pin shoulder, coupling thread and stress-transition area.

Handling and Storage

Sucker Rods are handled using equipment that prevents:

• Rod bending
• Body impact
• Thread damage
• Shoulder damage
• Surface scratches
• Coating damage
• Contact with corrosive chemicals

Storage requirements include:
