Product Description

SM  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".

The Spray Metal Sucker Rod Coupling is our most competitive product, which is processed with some special technology, and sprayed with a layer of abrasion-proof, wear-proof and lessening friction Nickel based alloy coat on the surface in a high temperature. It can not only protect itself but also the rod, preventing and slowing down the wear. The coupling has many types and sizes, and it is made of good quality steel alloy AISI 5140,covers Full Size, Slim Hole and Over Size, and has many types like Standard, Sub O.D, with big Chamfer, with Wrench Flat, with Bidirectional cambered surface protection, and so on. It has three basic functions: wear proof, corrosion-resisting and reducing the friction and its lifetime is also longer, even twice of class T coupling.

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
