Standard Specification for Welded Austenitic Stainless Steel Feedwater Heater Tubes
|Publication Date:||1 September 2004|
|ICS Code (Iron and steel pipes):||23.040.10|
The tubing sizes covered shall be ⅝ to 1 in. [15.9 to 25.4 mm] inclusive outside diameter, and average or minimum wall thicknesses of 0.028 in. [0.7 mm] and heavier.
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
