Description
This spreadsheet calculates the minimum required tube wall thickness at the U-bend region of U-tube heat exchangers per TEMA standards. It applies the TEMA thinning factor for bent tubes to determine required pre-bend wall thickness. Key inputs include tube outside diameter, bend radius, operating pressure, temperature, and material allowable stress. Key outputs include straight-section minimum thickness, U-bend minimum thickness, and recommended pre-bend wall thickness. Used by heat exchanger designers, mechanical engineers, and tube fabricators. Editable Excel format. Engineering support available — contact 3D-LABS.
