Choosing the right carbon steel grade
This is the shortcut we use when a customer describes the job rather than quoting a spec number.
| Grade | Standard | Pick it when |
|---|---|---|
| A106 Grade B | ASTM A106 | General process and refinery piping running hot, up to about 427°C. The default choice for plant piping in elevated-temperature service. |
| A53 Grade B | ASTM A53 | Structural and low-pressure utility lines where A106’s tighter chemistry is not required. Cheaper, less commonly used for pressure piping. |
| A333 Grade 6 | ASTM A333 | Low-temperature service down to minus 45°C. Impact tested — specify this for cold climates or any line that could see sub-zero conditions. |
| API 5L X42 to X60 PSL1/2 | API 5L | Standard-pressure gas and oil transmission pipelines. PSL2 adds mandatory impact testing and tighter carbon equivalent limits over PSL1. |
| API 5L X65 to X80 PSL1/2 | API 5L | High-pressure, long-distance transmission where a thinner wall at higher yield strength cuts total steel weight and freight cost. |
| API 5L LSAW / SAW | API 5L | Large diameters, typically above 20″, where seamless manufacturing is not practical or cost-effective. |
| API 5L IBR | Indian Boiler Regulations | Boiler and pressure vessel piping supplied into India, where IBR certification is a regulatory requirement, not optional. |
| ASTM A671 / A672 | ASTM A671 / A672 | Electric-fusion-welded pipe from plate, for moderate-temperature, high-pressure service — boiler feed lines, refinery process piping. Not the same product family as API 5L transmission pipe. |
Sizes and wall thicknesses
Carbon steel schedules follow ASME B36.10M. Density is 7.85 g/cm³: kg per metre = (OD minus WT) x WT x 0.02466, both dimensions in mm.
| NPS | OD (mm) | SCH 40 | SCH 80 | SCH 160 |
|---|---|---|---|---|
| 2″ | 60.3 | 3.91 | 5.54 | 8.74 |
| 4″ | 114.3 | 6.02 | 8.56 | 13.49 |
| 6″ | 168.3 | 7.11 | 10.97 | 18.26 |
| 8″ | 219.1 | 8.18 | 12.70 | 23.01 |
| 12″ | 323.9 | 10.31 | 17.48 | 33.32 |
