您可能需要与以下文章一起审查本文:
Fin Tube Heat Exchanger Inspection
This content guides you through all the necessary stages in the production of the鳍管热交换器,包括原材料,最终检查,保存和包装以及派遣到现场。beplay体育官网电脑
您需要考虑这一点:本文是为典型的鳍管热交换器and might not be detailed for special cases.
This content may be useful for second party inspectors,鳍管热交换器manufacturer quality control personnel, engineering companies, and purchasers, as well.
All鳍管热交换器inspection and testing is done against the approved drawings, purchase order specifications, purchasers or company standards, and within the practices and rules of the country, state or province and any government decrees, laws, ordinance or regulation as may apply.
.The applicable codes and specifications for a鳍管热交换器that is under the construction process is:
And the applicable codes and standard are:
The applicable codes and standard may be based other international standards, etc.该内容是一般的,如果设计代码与ASME和API代码不同,也可能有用。
Required Documents for Third Party Inspector Review:
通常在检查前的会议上同意文件列表,该会议是在实际开始检查工作前几周举行的。beplay体育官网电脑
参加这次会议的当事方是制造商,购买者和第三方检查机构代表。beplay体育官网电脑
This already explained in the Inspection and Test Plan for鳍管热交换器文章。
These are the list of documents which are normally agreed to be presented to the inspector:
The first actual inspection work on the鳍管热交换器是原材料检查。beplay体育官网电脑基于ASME代码,提供材料测试报告鳍管热交换器板是强制性的。对于其他组件,标记检查就足够了。beplay体育官网电脑
但是,如果采购订单要求为所有组件(例如喷嘴管,配件等)提供MTR,则制造商也需要提供它们。
For more details, you may review the thePressure Vessel Plate文章。
如上所述,通常可以在制造商的场所获得板块的原始或经过身份验证的磨机证书。
第三方检查员检查这些证书是否符合规格,并在适当的情况下进行图纸。
评论包括:
Then the inspector witnesses the plate material identification on the certificates against the plate marking. It is also necessary to check the identification with the鳍管热交换器drawing datasheet, material list and other specifications as appropriate.
还检查了切割板的转移标识。
Visual inspections for surface finish and probable defects are done and dimensional compliance with specification also needs to be controlled.
Structural support, pass partition, stiffener, plug, Louvre blade pivot pins, Louvre bearings,
钢百叶窗式叶片和帧、鳍、风机叶片,Plenums, fan decks, partitions, platforms and fan rings and Metal gasket materials are selected and inspected based of requirements of API 661 Clause 8.
当。。。的时候third party inspector carries out the material inspection, then provides the inspection visit report (IVR), the report contains the following items:
当。。。的时候鳍管热交换器raw material inspection is carried out, and the results were satisfactory or non-conformities were closed by remedial action, then the鳍管热交换器manufacturer will start fabrication.
第三方检查员检查了以下几点鳍管热交换器based on the inspection and test plan (ITP), which has already been agreed upon between the purchaser and the鳍管热交换器制造商。
The inspection scope is determined in the ITP. Some purchasers prefer to have stringent controls and assign the TPI for more “hold or witness points” for inspection and test activities, and some others prefer less “hold or witness points” and assign the TPI much more work in the “review document.”
这取决于购买者指定检查预算的预算。beplay体育官网电脑更多的检查将具有更大beplay体育官网电脑的成本和较小的风险,相反,较少的检查将具有更少的成本,但风险更多。
For more detail, review the Inspection and Test Plan for鳍管热交换器文章。本文中有ITP草案,我们认为这是最佳实践鳍管热交换器inspection.
