10305-6 Welded Cold Drawn Steel Tube For Hydraulic And Pneumatic Power Systems

10305-6 Welded Steel Tubes manufacture

The tubes shall be manufactured from hot finished welded tubes by cold drawing. Other suitable methods of cold working are permitted. The tubes shall be delivered in the delivery condition +N which means that after the final cold drawing operation the tubes are normalized in a controlled atmosphere.All non-destructive testing (NDT) activities shall be carried out by qualified and competent level 1, 2 and/or 3 personnel authorised to operate.

10305-6 Welded Steel Tubes Appearance

The internal and external surface finish of the tubes shall be typical of the manufacturing process and the heat treatment, and it shall be such that any surface imperfections such as ridges, dents or shallow grooves requiring dressing can be identified. It shall be permissible to dress, 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 and tubes containing these shall be deemed not to conform to this part of EN 10305.The tubes shall have smooth outer and inner surfaces with a roughness Ra 4 um, unless a reduced roughness of Ra 2 um is specified for the inner surface is specified.

Preparation of ends

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