Carbon Steel Heat Exchanger U-Tube OD 22mm from China
Bent seamless carbon steel U-tube with 22mm OD for shell-and-tube heat exchangers in refining and chemical processing. HTS 7304.39.0002 covers its non-alloy seamless circular profile and heat exchanger suitability, despite U-bend, as bending doesn't alter base tube classification. High fatigue resistance for thermal cycling.

Import Tips
• Document U-bend radius and tube sheet compatibility to affirm heat exchanger end use
• Require NDT (non-destructive testing) reports for seamless quality assurance at import
