1、波纹管应采用液压、滚压或冲压等整体成形方法成形
2、波纹管成形用的薄板卷制管坯只允许有全焊透的对接型纵向焊缝，不许有环向焊缝
3、膨胀节的焊接应符合ASME Ⅸ的规定
4、波纹管成形之前应对管坯纵向焊缝按ASMEⅤ进行100%射线探伤，成型后应对膨胀节焊缝按 ASMEⅧ-Ⅰ附录8进行100%渗透检测

1st, the corrugated pipe should use the hydraulic pressure, rolling orwhole forming method forming and so on the ramming
2nd, the corrugated pipe forming uses the thin steel platevolume system 管坯 only allows to have the entire penetration thedocking longitudinal welded joint, must not have the link to thewelded joint
3rd, the inflation festival welding should conform to the ASMEIX stipulation
4th, before corrugated pipe forming should V carry on 100% beamcrack detection to 管坯 the longitudinal welded joint according toASME, after takes shape should to inflate the festival welded joint 8to carry on 100% seepage examination according to the ASME VIII - Iappendix
