EN13445设计：无损检测

本文主要讲EN13445设备设计中的无损检测相关要求，无损探伤实操因为接触不多，也不好发表意见。

下图选自常规PED设备设计图纸的焊缝无损检测方法表。

常规设备的无损检测的质量等级是EN ISO 5817-C;

循环工况和蠕变工况的设备无损检测的质量等级是EN ISO 5817-B。

6.6.3.2   Quality level

The quality level shall be quality level C in accordance with EN ISO 5817:2014.

For cyclic loaded vessels, see Annex G;for vessels or parts subject to creep, see Annex F.

Annex G :To reflect this, Quality Level B of EN ISO 5817:2014 isthe reference quality level for maximum allowable welds imperfections in these critical areas.

Annex F:For vessels or vessel parts subject to creep, Quality Level B of EN ISO 5817:2014 is the reference quality level for maximum allowable imperfection in these areas.

 EN13445-5中对于无损检测检测技术及等级、验收标准直接引用EN ISO 17635标准的相关规定。 

6.6.3.5  Surface condition and preparation for non-destructive testing The surface condition necessary for performing all NDT shall be in accordance  with the standard for the corresponding testing technique as stated in EN ISO 17635:2010. 

EN ISO 17635: AnnexA :rules and standards to be applied
