压力容器检验

该压力容器检验article provides you information about the inspection of pressure vessels and pressure vessel tests in a manufacturing shop. You may want to review thepressure vessel inspection procedureand corresponding检验和测试计划

Pressure Vessel Definition-根据ASME规范第八节,压力容器是容器的压力安全壳,无论是内部还是外部。

该压力可以从外部源,或通过将热从一个直接或间接的源,或它们的任意组合的应用程序来获得。

点击有关压力容器的定义,范围,以及基于ASME边界和API代码特异性集中于压力容器检查上面的链接以获取详细信息。

ASME Code Section 8-ASME Code Section 8 is the construction code for Pressure Vessels.

这个代码部分地址强制性要求,具体禁止和压力容器材料,设计,制造,检验,检验,检测,认证和泄压非强制性的指南。

你可能知道,ASME规范第8部分有三个部门。司1个覆盖压力可达3000磅,2区具有改变规则,并覆盖到高达10000psi,以及3分部可用于压力高于10,000psi下更高。

此部分被分成三个部分:小节,强制性附录,和非强制性附录。

Subsection A consists of Part UG, covering the general requirements applicable to all pressure vessels.

Subsection B covers specific requirements that are applicable to the various methods used in the fabrication of pressure vessels. It consists of Parts UW, UF, and UB, and deals with welded, forged, and brazed methods, respectively.

C小节覆盖适用于几类的压力容器结构中使用的材料的具体要求。

它由零件UCS,UNF,UHA,UCI,UCL,UCD,超高温灭菌,ULW,和ULT的处理碳钢和低合金钢,有色金属,高合金钢,铸铁,包层和衬里材料,球墨铸铁,铁素体钢通过热处理,分层结构,和低温材料,分别增强的性质。

Pressure Vessel Plate Material- 你必须要小心选择Pressure Vessel Plate Materials; there are lots of requirements and specific prohibitions in the ASME code.

Some of these requirements are ASME and Non ASME plate material, plate specification, inspection requirement and material test report.

ASME规范二段VIII DIV 1要求的材料是,用于含有压力部分在ASME第二节指定的材料中的一种,但与它们在ASME规范二段VIII 1区在C小节例如指出一些限制UCS,UHF,UNF。

例如,SA 283板材在ASME SEC II列出,但是当你指的C小节中二段VIII 1区,你看到它不允许用于致命物质服务,以及为燃式蒸汽锅炉。betway MGS真人此外,当您需要厚度大于5/8英寸的,你不能使用这种材料。

ASME压力容器联合效率-You may know ASME Pressure Vessel Joint Efficiencies are linked to the radiography testing grades, and there is concession for full radiography testing per the UW-11(a) (5) (b) clause, which it is a little bit confusing.

Based on ASME Code requirements, manufacturers have to mark the type of RT, e.g. RT1, RT2, RT3 and RT4, in the pressure vessel name plate and state the same in the Pressure Vessel Data Report.

我们看到很多专业人士,包括检查员和谁是RT1和RT2之间混淆的质量控制工程师,特别是当他们看到ASME压力容器联合效率两个RT1和RT2是相同的,等于1(E = 1);

他们说,RT1和RT2无论是在UW-11条款的“全放射学”部分进行分类。那么,为什么在一些RT2关节点射线照相?我们正在做现场摄片,但它是在全摄片分类!

点击上面的链接到这个问题的答案,其中特别侧重于压力容器检验上。

ASME Impact Test Requirement-You need to take care about ASME Impact Test Requirement. Suggest you have pressure vessel in the design process and construction has not started yet.

Based on ASME impact test requirements, you need to make an assessment to see that either your pressure vessel is exempted from impact testing or you need to carry out the test.

该re are 4 steps for impact test exemption assessment. You need to go through these steps, and you might be exempted in the first, second or third steps, and might not be exempted in step 4;

所以,如果你在步骤4,你有没有免除,那么你需要进行试验。本文介绍了这个评估过程。

First, you have to keep your pressure vessel design data available and then refer to UG-20 (f), if you are exempted from this clause, you do not need继续anymore.

But if you are not exempted by UG-20 (f), you have to proceed to UCS-66(a). Again if you are exempted, there is no need for more assessment.

但是,如果没有,你必须进行UCS-66(B)。如果你现在豁免,不再需要更多的评估,否则你必须进行UCS-68(C)。同样,如果你仍然不能免除;你必须进行冲击试验。

It means for some cases we might be exempted from ASME impact test requirement in first stage in UG-20 (f), in others in UCS-66(a) or UCS-66(b) or UCS-68(c) or might not be exempted and must prepare for doing this costly test.

Ťhis test would be more costly out of the US because of the Laboratory Accreditation requirement. The Accredited Laboratory based US accreditation system is not used too much in Europe, the Middle East and other locations.

压力容器检验尺寸-你知道压力容器检验尺寸的要求是什么?你可能知道一些制造公差,还没有ASME规范第八节得到解决。

所以,你需要参考其他来源进行检查。压力容器的大部分维控制要么解决或没有在ASME规范解决。它们包括以下各项:

压力容器检验-Dimension

  • 板,管轧机Undertolerance
  • 公差封头
  • Out of Roundness of Shell
  • Nozzles and Attachments Orientation
  • 喷嘴和附件投影
  • Nozzles and Attachments elevation
  • Nozzles and Attachments levelness
  • 焊缝不匹配
  • 焊缝余高

Pressure Vessel RT Test-你知道你的压力容器RT测试的要求是?充满摄片必须为你的船?当全摄片是强制性的?什么验收标准?什么RT符号?

当以下条件之一存在,你需要做的全摄片:

  1. All butt welds in vessels used to contain lethal substances
  2. 在容器的所有对接焊缝,其中所述标称厚度超过指定值
  3. All butt welds in unfired steam boilers with design pressure > 50 psi
  4. All category A and D butt welds in a vessel when “Full Radiography” is optionally selected

正如你看到的,项目编号1,2和3是充分RT测试真的强制性的;

但是,压力容器制造商可在项目数4全摄影的可选判定。

Why would pressure vessel manufacturers want to spent more money for full radiography in item Number 4?

Because joint efficiency in full radiography condition is 1, and the higher joint efficiency in the pressure vessel wall thickness formula causes less wall thickness, so the manufacturer might save lots of money with a lower thickness plate material.

But code has given some bonuses to the manufacturer in item 4, because it is not mandated to do really full radiography in all butt welds. The manufacturer can do spot radiography in B and C joints with the same joint efficiency of 1.

Vessel Pressure Testing-你需要施工过程完成后做一个液压静力试验,但内部零件组装前,也是绘画过程之前。

请注意执行ins气动测试tead of the hydro-static testing is not allowed and it can be replaced only when it is not possible due to design and process.

容器压力测试的要求已经在UG-99和UG-100在ASME规范第八节事业部解决。1。

该activities are done in 3 stages; the activities before start of the test, the activities during test and the activities after the test.

Pressure Vessel Certification-你知道,压力容器认证过程是怎样的?如何压力容器制造商可以ASME邮票持有人?如何第三方检验公司可以通过ASME认证和授权检验机构?什么是“U”标记的压力容器?

你可能知道压力容器制造认证是一样的授权的ASME邮票。

该pressure vessel manufacturers can implement the ASME Quality Control System and then apply for ASME Stamp.

这意味着如果一个制造认可的SME organization for pressure vessel per ASME Code Section VIII Div. 1 can stamp the letter “U” in the pressure vessel nameplate. These are the processes for ASME Stamp Accreditation:

  • 获得ASME申请表格
  • 签署的授权检验机构(AIA)服务协议 -Authorized inspection Agencies are Third Party Inspection Companies that have been accredited by the ASME organization and their inspectors certified by the National Board Inspection Code (NBIC).该se Inspectors are named Authorized Inspectors and hold Commission Cards issued by the NBIC organization.Summary: AIAs are accredited by ASME, but the inspectors are certified by NBIC.
  • Submit Application Forms to ASME and Transfer Fees
  • Purchase ASME Code Books
  • Describe a QC-System according to the ASME Code Quality Control manual and have the procedures prepared by the manufacturer.
  • 准备一个示范项目 -一位代表演示压力容器需要构建和所有图​​纸,计算书,零件清单,采购订单,材料检测报告,捏造,检查,测试和报告应根据ASME规范第八节的要求。
  • 资格规程和工作人员 -品质管制Procedures and Personnel also need to be approved by manufacture.
  • 前联合审查通过AIA的主管 - 它需要近4 months to fulfill the above requirements. Then an audit needs to be conducted by a supervisor authorized inspector, which is designated by the authorized inspection agency, which is under contract with the manufacturer.该审计报告将在审计过程中发现的不符合项,然后制造商将有一些时间来改正。
  • Joint Review (Audit) with ASME Designee, Inspector and Supervisor -最后,审计将通过指定人员的ASME进行,监事授权检验师及授权检验师。Ťhat is the reason this audit is called a joint review.
  • 证书的颁发和邮票由ASME

如果审计的结果是令人满意的,该证书将通过ASME颁发,然后制造商将被授权邮票铭牌与“U”钢印。

Pressure Vessel Heads-How many standard Pressure Vessel Heads are in the ASME Code? What are their characteristics?

椭圆封头,半球形封头和蝶形封头三种类型ASME压力容器碟形首脑。

在相同的设计条件,如设计压力,设计温度和材料,在内部压力下的计算的壁厚为椭圆形头将约等于所述外壳的厚度。对于准球形头,该厚度等于的1.77倍ellipsoidal, and the shell thickness and for a hemispherical head is equal to half the shell thickness.

For example, if you have calculated your shell thickness under internal pressure and obtained 12 mm, your thickness for an ellipsoidal head will be approximately 12 mm; for a torispherical head, 20.4 mm; and for hemispherical head, 6 mm.

Ťhird Party Inspection for Pressure Vessel-What is the third party inspection requirement for pressure vessel inspection in a manufacturing shop?

Ťhis article provides information about pressure vessel inspection from material inspection to final inspection and dispatch to site.

检验和试验计划的压力容器-该Inspection and testing requirement is distributed in a different part of the construction code.

检验和测试计划有一个表格格式,并收集所有在一个简单的表格,这些要求,并确定了负责每一方,即制造商,第三方检查和购买。

Pressure Vessel Handbook-当有ASME规范第八节,为什么我们需要压力容器手册?哪些应用?所有的设计公式和计算方法都没有在ASME规范解决,也有在ASME规范没有制造公差。

So the Pressure Vessel Handbook assists us in covering all these requirements.

压力容器手册支持压力容器检验工程师,设计师,压力容器制造商的质量控制技术人员和工程师,以及谁与压力容器处理任何其他人。
