14、ure 3.1 Seamless tube for pressure system Unless otherwise specified by the material standard or order, the method of production shall be at the option of the manufacturer. Heat treatment shall be carried out under vacuum or protective atmosphere. Subsequent to a final reduction of the tube and prio
15、r to chemical milling, external surfaces may be conditioned by belt polishing with a grit of 38 pm, or finer. Internal surfaces may be conditioned by grit blasting with a grit not larger than 150 pm. After final reduction and conditioning, tubes shall be chemically milled to remove a minimum depth o
16、f 50 pm from the external surface and a minimum depth of 25 pm from the internal surface. After final heat treatment, rotary straightening of the tubes is not allowed. Stretch straightening up to a maximum of 2 % and light hand straightening is permissible. Straightening and stress relieving shall n
17、ot cause any defects prejudicial to the intended use. 3.2 Tube for purposes other than pressure system For seamless and welded tubes for purposes other than pressure system all requirements shall be defined on the order . 4 Inspection and testing 4.1 Non-destructive tests 4.1 . 1 Dimensions shall co
18、nform to the requirements of the order. Dimensions and tolerances Tolerances shall conform to the relevant dimensional standard stated by the material standard or order. Except for the measurements of wall thickness and diameters of tubes under pressure, the method and frequency adopted by the manuf
19、acturer shall be sufficient to enable him to certify compliance with the requirements. The wall thickness and outer diameter of each tube for pressure purposes shall be continuously determined and recorded over the entire length by either an ultrasonic method of measurement or an alternative method
20、agreed between manufacturer and purchaser. For all methods of measurement an agreed resolution shall be established. The internal diameter of these tubes shall be calculated from the measurements made. 4.1.2 Visual examination Tube shall be examined for internal and external surface defects by visua
21、l examination. Assessment of the surface quality shall be carried out by comparison with visual samples agreed between manufacturer and purchaser. Each tube shall be examined. Where necessary, boroscope examination shall be used to investigate suspected bore defects. The internal surface quality sha
22、ll also be assessed by examining longitudinally cut samples from the flattening and bending test (see 4.2.3 and 4.2.4).
