TREATING PRESSURE VESSELS |
| 摘要 |
<p>A pressure vessel has a cylindrical side wall and a closed end joined to the side wall at a knuckle. The fatigue resistance of the pressure vessel is improved by autofrettage which moves a region of peak stress from the internal surface of the vessel to a region within the knuckle. Preferred are pressurised gas vessels of 6000 or 7000 series aluminium alloys.</p> |
