Manufacturer nameplates are generally easier to locate than the ASME stamping. The ASME information is generally stamped on the drum (so that, even with component changes, the stamping is least likely to be removed). See ASME BPVC.I-2017 PG-111 “Location of Stampings” for more details. Pressure Vessel Nameplates Designed to safely house gases and liquids needed for tool and machine operation, pressure vessels play a pivotal role in most manufacturing and industrial processes. Improper identification, however, can cause unwanted downtime, workplace accidents, and even physical injury.

The Pressure Vessel Inspections article provides you information about the inspection of pressure vessels and pressure vessel tests in a manufacturing shop. You may want to review the pressure vessel inspection procedure and corresponding inspection and test plan.

Pressure Vessel Definition – Based on the ASME Code Section VIII, pressure vessels are containers for the containment of pressure, either internal or external.

This pressure may be obtained from an external source, or by the application of heat from a direct or indirect source, or any combination thereof.

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

This Code section addresses mandatory requirements, specific prohibitions, and non-mandatory guidance for pressure vessel materials, design, fabrication, examination, inspection, testing, certification, and pressure relief.

You may know that ASME Code Section 8 has three divisions. Division 1 covers pressure up to 3,000 psi, Division 2 has an alternative rule and covers up to 10,000 psi, and Division 3 can be used for pressure higher than 10,000 psi.

This section is divided into three parts: subsections, mandatory appendices, and non-mandatory appendices.

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.

Subsection C covers specific requirements applicable to the several classes of materials used in pressure vessel construction.

It consists of Parts UCS, UNF, UHA, UCI, UCL, UCD, UHT, ULW, and ULT dealing with carbon and low alloy steels, nonferrous metals, high alloy steels, cast iron, clad and lined material, cast ductile iron, ferritic steels with properties enhanced by heat treatment, layered construction, and low temperature materials, respectively.

Pressure Vessel Plate Material – You have to be careful when choosing 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 Code Sec VIII DIV 1 requires that materials that used for pressure containing parts are one of the materials specified in ASME section II, but with some restrictions which are stated in ASME Code Sec VIII Div 1 in subsection C e.g. UCS, UHF, UNF.

For example, SA 283 plate material is listed in ASME Sec II, but when you refer to subsection C in Sec VIII Div 1, you see it is not allowed to be used for lethal substance services as well as for unfired steam boilers. Also, you cannot use this material when you need your thickness to be greater than 5/8 of an inch.

ASME Pressure Vessel Joint Efficiencies – 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.

We have seen many professionals including inspectors and quality control engineers who are confused between RT1 and RT2, specifically when they see that the ASME Pressure Vessel Joint Efficiencies for both RT1 and RT2 is the same and is equal to 1(E=1);

They say both RT1 and RT2 are categorized in the “Full Radiography” part in UW-11 clause. So why are some joints in RT2 radiographed in spot? We are doing spot radiography, but it is categorized in full radiography!!!

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.

There 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;

So if you are in step 4 and you have not exempted, then you need to carry out the test. This article explains you this assessment process.

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 proceed 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.

But if not, you have to proceed to UCS-66(b). If you are exempted now, no need for more assessment, otherwise you have to proceed to UCS-68(c). Again, if you are still not exempted; you have to carry out impact testing.

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.

This 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.

Pressure Vessel Dimension Inspection – Do you know what the Pressure Vessel Dimension Inspection requirement is? You may know some fabrication tolerances have not been addressed in ASME Code Section VIII.

So you need to refer to other sources for inspection. Most dimensional controls of Pressure Vessels are either addressed or not addressed in the ASME Code. They consists of the following items:

Pressure Vessel Inspections – Dimension

  • Mill Undertolerance of Plates and Pipes
  • Tolerances for Formed Heads
  • Out of Roundness of Shell
  • Nozzles and Attachments Orientation
  • Nozzles and Attachments Projection
  • Nozzles and Attachments elevation
  • Nozzles and Attachments levelness
  • Weld Mismatch
  • Weld Reinforcement

Pressure Vessel RT Test – Do you know what your Pressure Vessel RT Tests Requirements are? Is full radiography mandatory for your vessel? When the full radiography is mandatory? What the acceptance criteria are? What the RT symbols are?

When one of following condition is existing, you need to do full radiography:

  1. All butt welds in vessels used to contain lethal substances
  2. All butt welds in vessels in which the nominal thickness exceeds specified values
  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

As you see, the item numbers 1, 2 and 3 are really mandatory for the full RT test;

But the pressure vessel manufacturer may make an optional decision for full radiography in item number 4.

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 – You need to do a hydro-static test after the completion of construction process, but before the internal parts assembly, and also before the painting process.

Please note that performing the pneumatic test instead of the hydro-static testing is not allowed and it can be replaced only when it is not possible due to design and process.

Vessel Pressure Testing requirements have been addressed in UG-99 and UG-100 in ASME Code Section VIII Div. 1.

The 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 – Do you know what the pressure vessel certification process is? How Pressure Vessel Manufacturers can be ASME Stamp Holders? How Third Party inspection companies can be certified by ASME and be Authorized Inspection Agencies? What is a “U” Stamped Pressure Vessel?

You may know pressure vessel manufacture certification is the same as the Authorization for the ASME Stamp.

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

It means that if a manufacture accredited by the ASME 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:

  • Obtain Application Forms from ASME
  • Sign a Service Agreement with an Authorized Inspection Agency (AIA) – 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).These 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.
  • Prepare a Demonstration Item – A representative demo pressure vessel needs to be constructed and all drawings, calculations, parts lists, purchase orders, material test reports, fabrications, inspections, tests and reports should be based on the ASME code section VIII requirement.
  • Qualify Procedures and Personnel – Quality Control Procedures and Personnel also need to be approved by manufacture.
  • Pre-Joint Review by the Supervisor of AIA – It takes almost 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. This auditor would report non-conformities found in the audit process, and then manufacturer would have some time to correct them.
  • Joint Review (Audit) with ASME Designee, Inspector and Supervisor – Finally the Audit would be conducted by an ASME designated Person, Supervisor Authorized Inspector and Authorized Inspector. That is the reason this audit is called a joint review.
  • Issuance of Certificate and Stamp by ASME

If the result of the audit was satisfactory, the certificate would be issued by ASME, and then the manufacturer would be authorized to stamps nameplates with the “U” Stamp.

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

Ellipsoidal Head, Hemispherical Head and Torispherical Head are three types of ASME Pressure Vessel Dished Heads.

Under the same design conditions, such as design pressure, design temperature and material, your calculated wall thickness under internal pressure for ellipsoidal head will be approximately equal to the shell thickness. For a torispherical head, the thickness is equal to 1.77 times that of the 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.

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

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

Inspection and Test Plan for Pressure Vessel – The Inspection and testing requirement is distributed in a different part of the construction code.

The inspection and test plan have a tabulated format and collect all these requirements in a simple table and determine the responsibly of each party, i.e. the manufacturer, third party inspector and purchaser.

Pressure Vessel Handbook – When there is ASME Code Section VIII, why do we need the Pressure Vessel Handbook? What are the applications? All design formulas and calculations methods have not been addressed in ASME Code, and also, there are no fabrication tolerances in ASME Code.

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

The Pressure Vessel Handbook supports pressure vessel inspections engineers, designers, pressure vessel manufacturer quality control technicians and engineers, and any other people who deal with pressure vessels.

Pressure Vessel Inspections and ASME IX

The ASME Code Section VIII refers to the ASME Code Section IX for welding procedure specification, procedure qualification record and welding performance qualification.

Essential variables are variables (such as P number, A number, F number) that directly affect the mechanical property of material so need the re-qualification of procedure qualification.

The nonessential variable is the variables that are not affecting the mechanical property. The WPS must be revised and no need to be re-qualified. The supplementary essential variable will be essential variable when construction code requires impact testing. An example of the supplementary essential variable is Group number.

ASME Section IX Bend Test – Provides information about bend test acceptance criteria for both Welding procedure qualification and welder performance qualification.

ASME Section IX Heat Input – The heat input calculation applicable to the WPS’s which impact test is a requirement by construction code e.g., ASME Section VIII Div. 1

ASME Section IX Radiography – ASME Section IX Radiography – The requirement only is applicable for welder and welding operator qualification.

The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels.[1] The document is written and maintained by volunteers chosen for their technical expertise .[2] The ASME works as an accreditation body and entitles independent third parties (such as verification, testing and certification agencies) to inspect and ensure compliance to the BPVC.[3]

History[edit]

The BPVC was created in response to public outcry after several serious explosions in the state of Massachusetts. A fire-tube boiler exploded at the Grover Shoe Factory in Brockton, Massachusetts, on March 20, 1905, which resulted in the deaths of 58 people and injured 150. Then on December 6, 1906, a boiler in the factory of the P.J. Harney Shoe Company exploded in Lynn, Massachusetts. As a result, the state of Massachusetts enacted the first legal code based on ASME's rules for the construction of steam boilers in 1907.[4][5]

Pressure Vessel Nameplate Information

ASME convened the Board of Boiler Rules before it became the ASME Boiler Code Committee which was formed in 1911. This committee put in the form work for the first edition of the ASME Boiler Code - Rules for the Construction of Stationary Boilers and for the Allowable Working Pressures, which was issued in 1914 and published in 1915.[5]

The first edition of the Boiler and Pressure Vessel Code, known as the 1914 edition, was a single 114-page volume.[6][7] It developed over time into the ASME Boiler and Pressure Vessel code, which today has over 92,000 copies in use, in over 100 countries around the world.[5] As of March 2011 the document consisted of 16,000 pages in 28 volumes.[7]

After the first edition of the Code, the verifications required by the Code were performed by independent inspectors, which resulted in a wide range of interpretations. Hence in February 1919, the National Board of Boiler and Pressure Vessel Inspectors was formed.[5]

Division 2 - Alternative Rules[edit]

This division covers the mandatory requirements, specific prohibitions and nonmandatory guidance for materials, design, fabrication, inspection and testing, markings and reports, overpressure protection and certification of pressure vessels having an internal or external pressure which exceeds 3000 psi (20700 kPa) but less than 10,000 psi.[18]

The pressure vessel can be either fired or unfired.[17] The pressure may be from external sources, or by the application of heating from an indirect or direct source as a result of a process, or any combination of the two.[18]

The rules contained in this section can be used as an alternative to the minimum requirements specified in Division 1. Generally the Division 2 rules are more onerous than in Division 1 with respect to materials, design and nondestructive examinations but higher design stress intensity values are allowed.[17] Division 2 has also provisions for the use of finite element analysis to determine expected stress in pressure equipment, in addition to the traditional approach of design by formula (Part 5: 'Design by Analysis requirements').

Division 3 - Alternative Rules for Construction of High Pressure Vessels[edit]

This division covers the mandatory requirements, specific prohibitions and nonmandatory guidance for materials, design, fabrication, inspection and testing, markings and reports, overpressure protection and certification of pressure vessels having an internal or external pressure which exceeds 10,000 psi (70,000 kPa).[19]

The pressure vessel can be either fired or unfired.[17] The pressure may be from external sources, by the application of heating from an indirect or direct source, process reaction or any combination thereof.[19]
