The internal and external surface finish of the tubes shall be typical of the manufacturing process and, where applicable, the heat treatment, and it shall be such that any surface imperfections such as ridges, dents or shallow grooves requiring dressing can be identified.

 

Any surface imperfections, whose depth cannot be clearly identified, or,

  • It shall be permissible to dress, only by grinding or machining, surface imperfections provided that, after doing so, the dimensions are within the specified tolerances. All dressed areas shall blend smoothly into the contour of the tube.
  • Surface imperfections which encroach on the specified minimum wall thickness shall be considered defects.

 

The tubes shall have smooth outer and inner surface. The roughness Ra shall be:

≤4 μm on the outer and inner surface of tubes in the delivery conditions +C and +LC.

≤4 μm on the outer surface of tubes in the delivery conditions +SR, +A and +N.

 

The tubes are tested by means of following norms

EN10002-1
