API 8C Oilfield Single String Elevator Links — 75 to 700 Tons for Deep Well Drilling
API 8C Oilfield Single String Elevator Links (50 to 750 Tons)
Product Description
Elevator Links (also known as weldless links) are designed to hang elevators from Top Drive Systems, Hooks, Beckets, or Link Adapters. They are essential handling tools in oil and gas well drilling operations, providing a secure connection between the hoisting equipment and the elevator that carries the drill string.
Each elevator link is forged from a single billet of high-strength alloy steel, heat-treated, and MPI (Magnetic Particle Inspection) tested. Additional material is added in critical wear areas for extended service life. The design safety factor and design verification conform to the requirements of API Spec 8C.
Every elevator link is proof-load tested to 1.5 times the working load before delivery, and each link is marked with a unique Serial Number for full traceability.
Key Features
- Integrally Forged Construction: Forged from a single billet of high-strength alloy steel, ensuring maximum structural integrity with no welded weak points.
- Extended Wear Life: Additional material is added in critical wear areas to significantly extend the link's lifespan.
- API Spec 8C Compliant: Design safety factor and design verification conform strictly to API 8C requirements.
- 1.5× Proof Load Tested: Every elevator link is proof-load tested to 1.5 times the working load before delivery.
- Full Traceability: Each elevator link is marked with a unique Serial Number for absolute safety and traceability.
- MPI Tested: 100% Magnetic Particle Inspection on every link to detect any surface defects.
