Description

3-1/2" Seamless Tubing – API 5CT, Multiple Grades and Weights

The 3-1/2" Seamless Tubing is a common production tubing size in oil and gas wells, designed to deliver fluids from the reservoir to the surface safely and efficiently. Manufactured to API 5CT specifications, this tubing is available in a range of steel grades such as J55, N80, L80, and P110 to meet the mechanical and environmental requirements of shallow, deep, or corrosive wells.

Seamless tubing ensures uniform wall thickness and superior mechanical properties, providing better resistance to collapse, burst, and tensile failure under pressure. This size is frequently used in vertical and deviated wells, as well as in wells with artificial lift systems such as ESPs and rod pumps.

End finishes include EUE (External Upset End), NUE (Non-Upset End), and premium gas-tight connections such as TSH BLUE or VAM TOP, depending on service conditions. Tubing is typically supplied in R2 (28–32 ft) or R3 (40–42 ft) lengths.
