THE COAT LAYER IS NI60A.
API 3/4” Class T Slim Hole Sucker Rod Coupling
1)Material: AISI 5140
2)Standard: API Spec 11B
3)Specification:
O.D.: 1-1/2”(38.10mm)
I.D.: 1-1/16”(26.99mm)
Length: 4”(101.6mm)
Weight: 0.47kg
4)Other Size: 5/8”; 7/8”;1”; 1-1/8"
5)Features: The Class T sucker rod couplings are manufactured with a through hardness of between 16 and 23 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.
We are the manufacturer of sucker rod couplings and can supply the high quality sucker rod couplings in low price with the hope to establish a long-term relationship with you.
