Choosing proper materials is key to ensuring the rigs’ performance.rock core drilling rig

 

  1. Structural materials: Use high-strength, corrosion-resistant titanium alloys or special steels. They withstand deep-sea pressure and resist seawater, sulfide corrosion.
  2. Sealing materials: Pick elastic materials resistant to temperature extremes and chemicals. They ensure waterproofing, protecting internal electrical components.
  3. Drill bit materials: Adopt super-hard materials like diamond composites, matching sulfide hardness to boost efficiency and lifespan.
