Discover the differences between Ceramic Liners and Bi-metal Liners, focusing on their distinct advantages, applications, and lifespans in drilling operations.
With the ongoing growth in the economy, the adoption of zirconia ceramic liners has become widespread. You might wonder, what sets Zirconia Ceramic Liners apart from Bi-metal Liners? Here's a detailed comparison:
Our company stands as the world’s premier supplier of ceramic liners mud pumps. We provide comprehensive solutions to meet all your requirements, supported by a specialized team ready to assist you in finding the perfect product.
Understanding Bi-metal Liners
Bi-metal liners combine the benefits of a forged wear-resistant outer sleeve with a high-chromium, corrosion-resistant inner sleeve. The outer sleeve undergoes free forging, while the high chromium inner sleeve is produced through centrifugal casting; post heat treatment, its hardness reaches 62 Rockwell C grade. The 45# forging material boasts a tensile strength greater than 610 MPa, yield strength over 450 MPa, an elongation exceeding 17%, and a hardness of HB180-200 (casting jacket at HB160-200). Depending on environmental conditions, the lifespan of these liners can last up to 800 hours.
The Advantages of Ceramic Liners
- Ceramic Liners are engineered from oxygen oxidation zirconium ceramics (sourced from non-metallic minerals), offering greater toughness than bi-metallic liners. They can exceed 4,000 hours of operational time.
- Zirconia Ceramic Liners excel in resisting oxygen-induced wear and corrosion. However, issues such as cylinder pulling involve complex factors, including material selection, gap size determination, installation accuracy, structural layout, surface roughness, and lubrication and cooling efficiency.
- The extended service life of Zirconia Ceramic Liners significantly cuts down costs related to transportation, labor, and storage in drilling activities and minimizes piston wear. They are particularly advantageous for deep oil reservoirs, challenging geological conditions, and offshore oil and gas extraction.
