Product Description

SUCKER ROD COUPLING 

Sucker Rod Coupling is a joint for Sucker rod, used in oil well downhole for oil pumping and Production. Sucker rod couplings are manufactured from high quality Alloy Steel AISI 5140, fully in accordance with API Spec 11B standard, including class SM coupling, class T coupling, Sub coupling, Full Size, Slim Hole and Over Size, and the thread size are available at 5/8", 3/4", 7/8", 1" and 1 1/8".
  
advantage for our sucker rod coupling 
1.Steel round bars for raw material, good alloy AISI 5140.
2.CNC precision sizes.
3.Rolled Thread, made by API standard Extrusion Tap, 10 thds/inch.
4.Manganides Phosphating on coupling whole body
5.Several times fine grinding make couplings excellent quality and a beautiful outlook.

TECHNICAL PROCESS 

Preparing material→Drill hole→Heat treatment→Rough turning( Lathe outer circle→Flat end face→Lather Chamfer→Mill wrench flat)→Surface treatment/ball blast→Spray weld→Mill out circle→Flat end face→Fine turning(Lathe inner hole→Flat end face→Lathe sunk hole→lather inner chamfer) → Thread tapping→Phosphating→Grind outer bevel→Grind wrench flat→Grind outer circle→Washing→Rust-proof treatment→Punching mark→Packaging→Leave the factory
