API SPEC 11B Sucker Rod Couplings, Class T

API SPEC 11B Sucker Rod Couplings, Class T
Product Detailed
Made in accordance with API standard, the couplings are high in quality and low in price. The basic material is AISI 5140.

Yunsheng is the professional manufacturer of API sucker rod couplings and has been in this business for many years.

We got the API certifivate on June 1, 2009. The couplings have been exported to many countries and enjoy high reputation from our customer.

1.API Class T Full Size sucker rod coupling 1)Material: Seamless Alloy Steel 40Cr (AISI 5140) 2)Standard: API Spec 11B  3)Size: 5/8"; 3/4"; 7/8"; 1"; 1-1/8"4)Features: The Class T coupling is manufactured with a through hardness of between 16 and 23 Rc. This result in high tensile and fatigue strengh for the coupling. The outside diameter is smooth to minimize stress concerntrations, and an accurate chamfer allows for controlled contact stress. The threads are rolled full form which results in compressive stresses at the thread root and improved fatigue resistance.

2. API Class T Slim Hole sucker rod coupling 1)Material: Seamless Alloy Steel 40Cr (AISI 5140) 2)Standard: API Spec 11B  3)Size: 5/8"; 3/4"; 7/8"; 1"; 1-1/8"4)Features: The Class T coupling is manufactured with a through hardness of between 16 and 23 Rc. This result in high tensile and fatigue strengh for the coupling. The outside diameter is smooth to minimize stress concerntrations, and an accurate chamfer allows for controlled contact stress. The threads are rolled full form which results in compressive stresses at the thread root and improved fatigue resistance.
