Corrosion Resistant L80 Oil Tubing 139 7mm - China

Item Details

Product Overview L80 oil casing is a high corrosion-resistant pipe specifically designed for oil and gas extraction in harsh environments.

The external diameter of this product is 139.7mm, capable of meeting the demands of high-temperature and high-pressure oil wells, particularly excelling in environments containing carbon dioxide and hydrogen sulfide.

L80 casing meets API 5CT standards and is widely used in the petroleum and natural gas industry.

Technical Specifications - Outer Diameter: 139.7mm - Wall Thickness: 7.11mm (various specifications available upon request) - Material: L80 alloy steel - Yield Strength: ≥ 552 - Tensile Strength: ≥ 655 - Length: Standard length is 9.14 meters (30 feet), can be customized.

- Connection Types: Various connection methods available to adapt to different downhole conditions.

- Temperature Range: Suitable for use in environments ranging from -20°C to +80°C.

- Corrosion Resistance: Optimized for environments containing H₂S and CO₂.

Product Features The L80 casing has excellent corrosion resistance, especially suitable for use in high-acid environments.

Its unique alloy composition allows it to effectively extend service life when facing corrosive media.

Additionally, the high-strength design of the L80 casing enables it to withstand higher downhole pressures, ensuring the safety of oil and gas extraction.

Through advanced manufacturing processes and strict quality control, the L80 casing demonstrates exceptional performance in mechanical properties and durability.

The surface of the L80 casing undergoes special anti-corrosion treatment, significantly reducing the corrosion rate and extending the service life of the pipe.

Application Scenarios The L80 casing is suitable for deepwater oil fields, shale gas wells, and other oil and gas extraction operations in highly corrosive environments.

Due to its corrosion resistance, the L80 casing can effectively prevent wellbore corrosion during long-term use, reducing maintenance costs.

In practical applications, the L80 casing has become the preferred material for many large oil and gas conies, widely used in complex oil and gas extraction projects.

Particularly in gas fields with high concentrations of carbon dioxide and hydrogen sulfide, the L80 casing demonstrates its superior anti-corrosion capabilities.
