Manufacture :Tubes shall be made by the seamlessprocess and shall be cold drawn.
Heat Treatment:
1)Cold-drawn tubes shall be heat treated after the finalcold-draw pass at a temperature of 1 200F [640C] or higher toensure ductility satis factory for rolling into tube sheets and tomeet mechanical properties as specified.
2)If stress -relief anneal of the U-bends is specified, theanneal shall consist of heating the bent portion within a rangeof 1100 to 1200F [585 to 640C].
Outside diameter and wall thickness allow deviation mm
