ASME formed an Ad Hoc Task Group asem Post Construction in in response to an vownload for recognized and generally accepted engineering standards for the inspection and mainte-nance of pressure equipment after it has been placed in service.
The scope of this committee was to develop and maintainstandards addressing common issues and technologies related to post-construction activities andto work with other consensus committees in the development of separate, product-specific codesand standards addressing issues encountered after initial construction for equipment and pipingcovered by Pressure Technology Codes and Standards.
Frew BPTCS covers non-nuclear boilers,pressure vessels including heat exchangerspiping and piping components, pipelines, andstorage tanks. The PCC selects asme pcc-1-2013 free download to be developed based on identified needs and the availability ofvolunteers. Other topics are under consideration asme pcc-1-2013 free download may possibly be developedinto future guideline documents. The subcommittees were charged with preparing standards dealing with several aspects of thein-service inspection and maintenance of pressure equipment and piping.
If it is determined that repairs are required, guidance on repair proce-dures is provided in the appropriate portion of the Repair of Pressure Equipment and Piping Standard PCC To provide all stakeholders involved in asme pcc-1-2013 free download equipment with asme pcc-1-2013 free download guide to identifypublications related to pressure equipment integrity, a Guide frde Life Cycle Management ddownload PressureEquipment Integrity has been prepared PTB None of these documents are Codes.

The bolted flange joint assembly BFJA guidelinesdescribed in this document apply asme pcc-1-2013 free download pressure-boundaryflanged joints with pcc--12013 gaskets that are entirelywithin the circle enclosed by the bolt holes and with nocontact outside fref circle. Diwnload of the activities essential to leak-free per-formance is the joint assembly iis 6 windows server. It isrecommended that written procedures, aasme features of these guidelines that are deemed suitableto the x8 free download for pc application under consideration, be devel-oped for use by the joint assemblers.
Alternative featuresand methods for specific applications may be used sub-ject to endorsement by the user or his designated agent. It is recommended that the user or his designatedagent provide, or arrange to have provided, as appro-priate, essential training and qualification testing of thejoint assembly personnel asme pcc-1-2013 free download will больше информации expected to followprocedures developed from this Guideline.
See section F-2 of Appendix F for comments onaccepting flange joint assembly procedures not currentlylisted in these guidelines. Before assembly is started, clean and examine flangeand fastener contact surfaces as described in this section. Pcx-1-2013 usingcarbon steel brushes on downlpad steel flanges. The exception based on experience is flexible graphitethat may remain in the surface finish eownload wheneither a flexible graphite clad or a spiral-wound gasketwith flexible graphite filler is to be dlwnload as the replace-ment gasket.
Indica-tions running radially across the facing are of particularconcern. Refer to Appendix D for guidelines coveringrecommended limits on gasket contact surface imperfec-tions and their locations. Appendix C provides recom-mended final surface finishes. This may beaccomplished in many cases using a machinists straightedge and feeler gages, but using a securely mountedrun-out gage or field machining equipment capable of.
Appendix Dprovides flatness tolerance recommendations. Appendix C provides recommendedfinal surface finishes. If sepa-rate washers are scored or cupped from previous use,replace with new through-hardened washers3. For larger bolt страница, it is recom-mended that the cost of cleaning, deburring, and recon-ditioning be compared to the replacement cost andconsidered in the assessment of critical issues of theassembly. When assessing the cost, consider that work-ing with and reconditioning fasteners asme pcc-1-2013 free download the field maybe more expensive than the cost of replacement and thatthe results of reconditioning can be unpredictable.
Whencoated asme pcc-1-2013 free download are used, the remaining corrosion protectionand self-lubricating functions are additional considera-tions with respect to continued нажмите для деталей or replacement.
The process will remove thread material;therefore, the user is cautioned to ensure the tolerancelimits of ASME B1. However, it is generally recognizedthat the use asme pcc-1-2013 free download through-hardened diwnload washers will improve thetranslation of torque input into residual pc-1-2013 stretch. See Appen-dix M for a suitable through-hardened washer specificationguideline.
Any fastener with thread dimensionsless than the minimum major diameter or the minimumpitch diameter should be replaced. Appendix N provides supplementary information onthe bolt reuse topic. Coatings over approxi-mately 0. Roughness, gouges, and protrusionsshould be removed xownload these surfaces. On severelydamaged flanges, machining this area may be required,in which case the minimum asme pcc-1-2013 free download residual flangethickness must be considered.
The use of through-hard-ened, flat washers4 may be appropriate to providesmooth and square nut-bearing surfaces. Proper alignment of all joint members is the essentialelement of flange joint assembly. It results in maximumsealing surface contact, maximum opportunity for uni-form and design-level gasket loading, and reduced fric-tion between the nut and the flange. Guidelines foraligning flanged joints pcc-1-013 provided in Appendix E.
Place a new gasket in position after determining theabsence of or having made correction for unacceptablegasket sealing surface imperfections and asme pcc-1-2013 free download toler-ance deviations, as well as joint alignment considera-tions see Appendices D and E. Reuse of a gasket is generally not recommended. Onecurrent exception is large, grooved metal gaskets withfacing layers see Appendix C that are reused in someinstances after having been reconditioned and refacedin ssme manner consistent with the original product specifi-cations.
Use of gaskets so refurbished is not consideredas gasket reuse in the context of the first sentence. Forother gasket types, experience has clearly shown thatonly a new gasket will reliably provide the necessaryplastic deformation and elastic recovery characteristicsessential to achieve an effective seal.
Visual or physicalinspection of a used gasket for apparent damage is not. These are important considerations when torquingmethods either manual or hydraulic are used for bolt tightening.
Flat washers aske promote improved load distribution. See Appen-dix M for a suitable through-hardened washer purchase specifica-tion guideline. M 85M M See section 12 Target Torque Determination.
The root areas are based on coarse-thread series for sizes M27 and smaller,and 3 mm pitch thread series for sizes M30 and larger. Examination of Flange and Fastener Contact Surfaces and section 7 Lubrication of WorkingSurfacesand the asme pcc-1-2013 free download coefficients of friction: 0. These coefficients were selected to make the computed Target Torques consistentwith that needed for a Target Ссылка на страницу of MPa as independently verified by accurate boltelongation measurements больше информации several users.
See Appendix K for equivalent nut factors. See Appendix K forequivalent nut factor. For second and frer tightening by torquing methods,use of lubricants and torque values as specified for noncoated bolts is recommended. The root areas are based больше информации coarse-thread series for sizes asme pcc-1-2013 free download in. These coefficients were selected to make the computed Target Torques consistentwith that needed for a Target Читать далее of 50 ksi as independently verified by accurate boltelongation measurements by several users.
Noportion правы. download elsword indonesia exe это the gasket should project into the flow path. Downloax care should be taken to avoid adhesive chem-istry that is incompatible with the process asme pcc-1-2013 free download or couldresult in stress corrosion cracking or pitting of the flangesurfaces. Do not use tape strips radially across the gasket tohold it in position.
Do not use grease.
