IMRI’s L80-1 high-quality seamless tubing is manufactured in strict accordance with API 5CT standards. The addition of chromium (0.40%-0.60%) significantly improves corrosion resistance, making it suitable for harsh well conditions containing CO₂/H₂S. It also offers high strength (80,000 psi yield strength), crack resistance, and long-term reliability.

N80 VS L80
Selecting the right casing pipe grade is critical for the success and safety of drilling and production operations in the oil and gas industry. Here is a summary to help make an informed decision:
N80 tubing Pipes: Suitable for standard drilling operations where moderate strength and toughness are required. They are cost-effective and appropriate for non-sour environments and moderate well depths.
L80 tubing Pipes: Designed for challenging environments, including those with sour gas (H2S) presence. They offer superior corrosion resistance and mechanical properties, making them ideal for deeper, highpressure, and high-temperature wells.
