What are common coiled tubing sizes?

Here are some of the most common coiled tubing sizes used in the oil and gas industry:

Outer Diameter (OD):
- 1 inch (25.4 mm)
- 1.25 inches (31.75 mm)
- 1.5 inches (38.1 mm)
- 1.75 inches (44.45 mm)
- 2 inches (50.8 mm)
- 2.375 inches (60.325 mm)
- 2.875 inches (73.025 mm)

Wall Thickness:
- 0.087 inches (2.21 mm)
- 0.109 inches (2.77 mm)
- 0.134 inches (3.40 mm)
- 0.156 inches (3.96 mm)
- 0.175 inches (4.45 mm)
- 0.203 inches (5.16 mm)

Typical lengths range from 15,000 to 30,000 feet (4,572 to 9,144 meters), though exact lengths vary based on the specific application and equipment capabilities.

The choice of size depends on factors like well depth, pressure requirements, fluid flow needs, and the specific operation being performed. Smaller diameters are often used for deeper wells or higher pressure applications, while larger diameters allow for greater fluid flow rates.
