Roundness: Ensures precise dimensional accuracy for smooth operation.
Coaxiality: Optimizes the alignment between components, reducing wear during transmission.
Surface Roughness: Creates a smoother surface to minimize friction.Additionally, the extrusion forming in cold heading generates residual compressive stress on the surface of bushings and rollers, significantly improving their fatigue strength and durability under cyclic loads.
Widened Waist Dimension: Compared with standard chains, the waist of oil field chain plates is widened to increase the stress-bearing area. This modification boosts three core capabilities: load-carrying capacity, fatigue resistance, and operational stability, enabling the chain to withstand extreme tensile forces during oil field operations.
Steel Ball Hole Extrusion Post-Heat Treatment: After heat treatment, the link plates undergo a specialized process where hardened steel balls are used as "extruders." Through forced pressing or reciprocating extrusion, the surface layer of the hole wall undergoes plastic deformation and forms residual compressive stress. This stress counteracts part of the tensile stress exerted on the workpiece during operation, effectively inhibiting the initiation and propagation of cracks.
Adaptability to harsh environments: Capable of operating stably in the severe conditions of oil drilling and extraction.
High load-bearing capacity: Widened link plates and optimized component design enable the chain to bear ultra-high operational loads.
Excellent fatigue resistance: Residual compressive stress from cold heading and steel ball extrusion enhances the chain's service life under cyclic impacts.
Operational stability: Precise manufacturing and structural optimization ensure smooth transmission even at high speeds.
