Coil tubing/Coiled tube
What Is Coil Tube?
A coil tube refers to a continuous length of steel tubing that is wound into a coil shape for compact storage, transportation, and ease of use in various applications. Coil tubing is commonly made from materials like stainless steel, copper, or other alloys. It is used across industries for its durability, flexibility, and ability to minimize the number of joints or fittings in a system.

Test Requirements for ASTM A269 Tubes
- Chemical Composition Analysis:
- Tensile Testing:
- Hardness Testing
- Flare Test (for Seamless Tubes):
- Flattening Test:
- Hydrostatic or Nondestructive Electric Test:
- Hydrostatic Test: Tubes are subjected to internal pressure higher than their operating pressure for a specified time.
- Nondestructive Test: Ultrasonic or eddy current testing is performed as an alternative to hydrostatic testing.
- Dimension Testing.
