The GB/T 34204 standard specifies the requirements for seamless low carbon alloy steel tubes used in coiled tubing applications in the petroleum industry. These tubes are designed to withstand high pressures and temperatures, making them suitable for various oil and gas extraction processes.
The standard outlines the specifications for different grades of coiled tubing, including CT55, CT60, CT70, CT80, and CT90. Each grade has specific mechanical properties and chemical compositions tailored for various operational requirements.
The chemical composition of the low carbon alloy steel tubes is critical for ensuring their performance in demanding environments. Below is a table summarizing the chemical composition for each grade:
| Grade | C (%) | Mn (%) | P (%) | S (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|
| CT55 | 0.10 | 0.30-0.60 | ≤0.020 | ≤0.010 | 0.50-1.00 | ≤0.50 | ≤0.10 |
| CT60 | 0.10 | 0.30-0.60 | ≤0.020 | ≤0.010 | 0.50-1.00 | ≤0.50 | ≤0.10 |
| CT70 | 0.10 | 0.30-0.60 | ≤0.020 | ≤0.010 | 0.50-1.00 | ≤0.50 | ≤0.10 |
| CT80 | 0.10 | 0.30-0.60 | ≤0.020 | ≤0.010 | 0.50-1.00 | ≤0.50 | ≤0.10 |
| CT90 | 0.10 | 0.30-0.60 | ≤0.020 | ≤0.010 | 0.50-1.00 | ≤0.50 | ≤0.10 |
The mechanical properties of the coiled tubing are essential for ensuring their durability and performance under operational conditions. The following table presents the mechanical properties for each grade:
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| CT55 | ≥ 380 | 450-550 | ≥ 20 | ≤ 200 |
| CT60 | ≥ 450 | 500-600 | ≥ 18 | ≤ 210 |
| CT70 | ≥ 500 | 550-650 | ≥ 16 | ≤ 220 |
| CT80 | ≥ 550 | 600-700 | ≥ 14 | ≤ 230 |
| CT90 | ≥ 600 | 650-750 | ≥ 12 | ≤ 240 |
