The Class T Sucker Rod Coupling:Our Class T coupling is using AISI ***0 to manufacturer.The coupling is coated using phosphate chemical treatment .The couplings are availble in full size,slim hole andover size.
Material: AISI ***0 Standard: API Spec *1B
Specification: O.D.: 1_1/2”(*8.*0mm) I.D.: *5/*6”(*3.*1mm) Length: 4”(**1.6mm) Weight: 0.*6kg
Other Size: 3/4”; 7/8”;1”; 1_1/8”5
Features: The Class T sucker rod couplings are manufactured with a through hardness of between *6and *3 Rc. This results in high tensile and fatigue strength for the sucker rod couplings. The outside diameter of the sucker rod couplings is smooth to minimize stress concentrations, and an accurate chamfer allows for controlled contact stress.
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
