第三方检查储罐beplay体育官网电脑- Procedure

The Third Partybeplay体育官网电脑储罐的检查文章提供了在商店和现场进行储罐检查和测试的示例程序。beplay体育官网电脑您可以查看storage tank inspection and test planwith this procedure.

This content guides about all necessary stages in the production of the storage Tanks from the examination of material, welding, fabrication, NDE, dimensional inspection to the final inspection, preservation and packing to despatch to site. This content is primarily for mill and prefabrication stages with site erection being covered in outline only.

You need to take this point in account this article is written for a typical storage Tank and might not be complete for special cases.

All storage Tank inspections and tests are carried out 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 the Storage Tank which is under construction process are:

  • Design code
  • Purchase order specification
  • 购买者的标准
  • 批准的图纸

适用的代码和标准是:

  • API 650
  • API 620

The applicable codes and standard may be based other international standards such as BS 2654 and etc. This content is general and can be useful if even the design code is different from API Code.

第三方检查员审查所需的文件:

The list of documents normally is agreed in the Pre Inspection meeting which is hold several weeks before actual commencement of inspection work. The parties which are participated in this meeting are manufacture, purchaser andthird party inspection agencyrepresentatives.

These are the list of documents which are normally agreed to be presented to the inspector:

第三方检查储罐beplay体育官网电脑- Material Inspection

The first actual inspection work in the storage Tank is raw materials inspection.

The original or authenticated copies ofmill test certificatesof material normally are available at manufacturer's premises.

The third party inspector examines these certificates for compliance with specifications and where appropriate, drawings.

评论包括:

  • 证书号码。
  • Heat or cast No.
  • Chemical composition.
  • Mechanical properties.
  • Heat treated condition.
  • NDE applied and results.
  • Surface finish

Then the inspector witnesses the materials identification on the certificates against materials marking. It is also necessary to check with storage Tank drawing datasheet, material list and other specification as appropriate.

The identification such as Heat No. needs to be transferred to cut off components.

目视检查表面表beplay体育官网电脑面表面和可能的缺陷,还需要控制对规范的维数。

When the third party inspector carried out the material inspection, then provides inspection visit report (IVR), the report contains following items:

  • 确认令人满意的文件审查
  • Record of the endorsement of certification reviewed/witnessed
  • Record of all non-conformities
  • 目睹的任何测试的记录和结果

第三方检查储罐beplay体育官网电脑- Fabrication Inspection

When the storage tank material inspection carried out and result was satisfactory or non-conformities closed by remedial action, then storage tank manufacture will be authorised to start fabrication.

检查范围beplay体育官网电脑是在ITP中确定的,一些客户更喜欢拥有严格的控制,并将TPI检查员放入更多“hold points” in fabrication activities and some others may take lesser “hold points” and put TPI much more in the review document.

This depend to the inspection budget which client assign for inspection, much more inspection will have much more costs and less risks and conversely less more inspection will have less costs but more risks.

Third party Inspector is pays attention to the following points on a basis to be outlined in the purchaser's documentation, quality plan, test and inspection plan, or other document, as notified to the inspector.

第三方检查储罐准备beplay体育官网电脑

Third party inspection carries out visual and dimensional check to ensure compliance with WPS and specification. Where specified, weld bevels are examined by MT or PT after grinding/machining.

Edges and weld bevels need to be clean, dry and free from surface defects,laminations, cracks, voids, notches, etc.

These are causes for rejection unless suitable/satisfactory remedial action can be taken. Welding repairs to bevels are not permitted, without approval from the engineer/inspector. Inspectors needs report excessive or serious defects.

Plates subject to forming, rolling or dishing may require additional heat treatment and NDE to meet code requirements.

第三方检查储罐壳式课程和beplay体育官网电脑包含焊接接缝的底​​板

This stage inspection is carried out when plates have been tacked using welding consumables and other parameters from an approved WPS.

Third party Inspector checks and report on:

  • Cleanliness and fit up accuracy of weld preparation.
  • 板的平坦度,预防失真的方法,例如测序的焊接,强力,后退等。
  • Application of preheat.
  • Storage and handling of welding consumables.
  • 焊接正在进行的相互通行条件。
  • 清洁焊缝。
  • 完成测试优惠券(指定)
  • NDE。结果需要满足规格或代码要求。
  • Hardness tests - when specified.
  • Impact tests - when specified.

Weld repair may be permitted in accordance with the code requirements and is carried out only after investigation of the probable cause and in accordance with approved WPS documents.

所有焊接维修都需要由第三方检查员报告给客户。
