Api sucker rod coupling

Key Attributes.

Based on the spray metal sucker rod coupling, sucker rod coupling with big chamfer increases a big chamfer at both ends, greatly reducing the contact area with the pipeline, but also slowing down the wear. So it can not only protect itself better, but also the pipeline. so that the life of the coupling and pipeline are significantly Prolonged,and the operating costs of oil reduced, oil production increased. API Sucker Rod Coupling with Big Chamfer 1) Standard: API Spec 11B 2) Basic Material: AISI5140(high quality carbon steel ) 3) Coat Material:Ni60A Alloy Coating 4)Type: full size and slim hole 5) Coupling diameter :5/8"; 3/4"; 7/8"; 1"; 1-1/8" Moreover, Yunsheng sucker rod coupling includes SM sucker rod coupling,T sucker rod coupling, Sub sucker rod coupling, Full Size sucker rod coupling, all of them are up to API 11 B and available in size of 5/8", 3/4", 7/8", 1"and 1-1/8" If you are interested in any of our sucker rod couplings, please contact us freely.
