Created on：2021-08-08 17:44
Wireline triple tube core barrels are primarily used in deep coring. With an overshots device, they eliminate the need to couple and uncouple the rod string each time the core is retrieved.
Our head assembly features long life span, goods compatibility with parts like inner tube and outer tube from other vendors, and availability in all spare parts.
All products with ISO Certificate & quality control.
