This 5.5″ 23# 13CRM-110 VAM TOP R3 tubing is manufactured from Modified 13 Chrome (13CRM), a quenched and tempered martensitic stainless steel designed for improved performance in sweet (CO₂) environments with moderate to high chloride exposure. Offering enhanced strength and corrosion resistance up to 350°F, it’s well-suited for deeper, high-pressure wells. The VAM TOP connection provides premium gas-tight sealing and structural reliability, making this a strong choice for demanding downhole applications where standard 13Cr may fall short.
