Centralizer Maintenance Guide

Regularly inspect centralizers for wear, paying close attention to blade edges and hinge points. Replace immediately if cracks or deformation are found. Use specialized cleaning agents to remove drilling fluid residue during cleaning. Apply high-temperature grease to bearing areas every 50 hours.

Store centralizers vertically in a dry environment, avoiding contact between rubber components and oil-based solvents. Perform a no-load test before downhole operations to ensure the hydraulic system is leak-free and the spring mechanism rebounds normally. Record the pressure curve as baseline data.
