Appearance

The tubes shall be free from external and internal surface defects that can be detected by visual examination.

The internal and external surface finish of the tubes shall be typical of the manufacturing process and,where applicable, the heat treatment employed. Normally the finish and surface condition shall be such that any surface imperfections requiring dressing can be identified.

It shall be permissible to dress, only by grinding or machining, surface imperfections provided that, after doing so, the wall thickness in the dressed area is not less than the specified minimum wall thickness. 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 and tubes containing these shall be deemed not to conform to this Part of this EN 10216.

Internal soundness

Leak-tightness

The tubes shall pass a hydrostatic test or electromagnetic test for leak-tightness.

Non-Destructive Testing

Option 6: The tubes of quality TR2 shall pass a non-destructive test for the detection

Straightness

The deviation from straightness, of any tube length L shall not exceed 0,0015 L. Deviations from straightness over any one metre length shall not exceed 3 mm.

Preparation of ends

Tubes shall be delivered with square cut ends. The ends shall be free from excessive burrs.

Tolerances

Tolerances on diameter and thickness

Out-of-roundness is included in the tolerances on outside diameter and eccentricity is included in the tolerances on wall thickness

Tolerances on outside diameter and on wall thickness

Outside diameter (D mm)	Tolerances on D	Tolerances on T for a T/D ratio

Marking

The marking shall be indelibly marked on each tube at least at one end. For tubes with outside diameter D 51 mm the marking on tubes may be replaced by the marking on a lable attached to the bundle or box.
