The Spray Metal Sucker Rod Coupling:  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 ***0,covers Full sizes,Slim hole and Over size ,and has many types like Standard,Sub OD ,with Big Chamfer ,with Wrench Flat,with Bidirectional Cambered surface protection. 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. API 5/8” Class SM Full Size Sucker Rod Coupling

Unique Strong point

1.It's much better than Class T sucker rod couplings especially under the bad condition and the service life lasts *0 times than before.

2.The wear of the tubing is reduced 3 times after using it.

3.The size of the coupling is not changed too much; there is also no additionnal requirement for the operation under the well. The

usage stays the same.

4.prolonging the period of repairing well(maintaining pipe),reducing the cost of well repair,increasing the productivity and using rate of the oil well.

5.Reducing the friction resistance by ****5%,saving land electricity waste, increasing the operating safety, decreasing the accident.

6.The connection of rod is simple and the technology management is convenient.
