What is the maximum thickness generally supplied for coiled aluminum tubing?

The maximum thickness generally supplied for coiled aluminum tubing is 3/8 inch. This specification is significant because it aligns with industry standards and manufacturing capabilities for aluminum tubing, allowing for flexibility in applications while ensuring structural integrity. Coiled tubing is often used in various systems, especially in HVAC and refrigeration, where lightweight, corrosion-resistant materials are advantageous.

The choice of 3/8 inch reflects a balance between ease of handling and sufficient wall thickness for necessary strength and durability in common applications. Thicker aluminum tubing can be produced, but it is typically not supplied in coiled form due to the challenges in coiling and the increased rigidity that higher thicknesses provide. Understanding the limitations and applications of coiled aluminum tubing is crucial for pipe fitters to ensure they select the appropriate materials for a given job, maximizing efficiency and reliability in their work.
