Hydraulic slip system
Elevator link (single arm) 1. Implement API 8C, 7K and other relevant implementation standards and obtain national production license 2. Selection of high-quality alloy steel die forging forming 3. Strength check with ABAQUS finite element analysis, and electrical method for stress testing 4. Adopt secondary shot peening surface strengthening process
Elevator link (both arms) 1. Implement API 8C, 7K and other relevant implementation standards and obtain national production license 2. Selection of high-quality alloy steel die forging forming 3. Used for shallow wells and workover operations. 4. This double arm rings are used in pairs.
