ASME 质保书要求

我司正在进行的一个项目，ASME敲钢印的，这次来的AIS说，钢板是必须要质保书的，钢管和锻件质保书规范中没有强制要求提供质保书，AI可以尽义务帮助审查下钢管与锻件的质保书，但是钢管和锻件的质保书AI不需要签字；换证的时候，AI也会建议持证单位不要主动拿出钢管和锻件的质保书，只有要求了才拿出来。请问各位遇到过此问题吗？另外，规范中何处的依据？

我也参加过原来公司ASME U 钢印申请，但是我们钢板，无缝管，还有法兰都是有供应商提供的质保书的，所以保险起见，这三样还是要主动向供应商索要，特别是在取换证的时候，对于质保书的规范性联检组会有比较高的要求，在向供应商索要质保书的时候，最好先征求AI的意见，尽可可能的要求供应商按要求提供合格的质保书。

是的，这个我们目前也是这样做的，都要质保书，都要AI审查，如果不行就要供应商改换，但是AI说的规范上只需要钢板要质保书，出自那一条？

UG-93, see below quotation:
(1) For plates, the vessel Manufacturer shall ensure
all requirements of the material specification, and all special
requirements of this Division, that are to be fulfilled
by the materials manufacturer have been complied with.
The Manufacturer shall accomplish this by obtaining certificates
of compliance or Material Test Reports. The
Inspector shall determine if these documents represent the
material and meet the requirements of the material specification.
(2) For all other product forms, the material shall be
accepted as complying with the material specification if
the material specification provides for the marking of each
piece with the specification designation, including the
grade, type, and class if applicable, and each piece is so
marked.
i think either AIS or AI has the obligation to tell you the source of such requirement if you ask the question.

thank you very much, well noted, fred_king !
