A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers average or minimum-wallthickness

3、welded tubes made from various grades of austeniticalloy steel materials in which the (1) external tube surface, (2)internal tube surface, or (3) both internal and external tubesurfaces have a textured configuration for improved heattransfer or fluid flow or both. Texture surface(s) are producedby c

4、old forming a specified configuration on the surface(s) ofbase strip material, prior to welding. The produced weldedtextured tubes may be used in boilers, superheaters,condensers, evaporators, heat exchangers, and other similarheat transfer apparatus in diameters up to and including 1.5 in.38 mm for
