API 653 för inspektion av lagringstankar ovanför jorden (kredit: freepik)
Innehållsförteckning
Vad är API 653?
API 653 är en uppsättning standarder för att utföra inspektion, reparation, ändring och rekonstruktion av ovanjordiska lagringstankar (AST) som används i petroleum- och kemisk industri. API 653, utfärdat av American Petroleum Institute (API), säkerställer att tankägare och operatörer följer säkerhetsåtgärder och håller sina tankar på högsta prestanda. API 653-riktlinjer täcker flera aspekter:
- Obligatoriska krav på tankundersökning
- Rutiner för reparationer och förändringar
- De kvalifikationer som krävs för personal som arbetar med tankunderhåll
- Papper för inspektioner och reparationer.
Standarderna för API 653 är avgörande för att förhindra eventuella missöden som kan utsätta allmänheten för risker och orsaka miljöskador.
Vad omfattar API 653?
API 653 täcker standarden för tankar med en diameter större än 30 fot och en höjd högre än 50 fot. Dessa ovanjordiska lagringstankar (AST) är skapade för att lagra stora mängder vätskor eller gaser, inklusive men inte begränsat till vatten, petroleum, bensin, kemikalier och farligt avfall. Det gör API 653 till en nödvändig standardkod för petroleum- och petrokemisk industri.
Vilka är de kritiska komponenterna i API 653 (lagringstank) inspektion?
Några kritiska komponenter i en API 653-inspektion nämns i det följande.
- Allmän tankinformation
Informationen inkluderar tankspecifikationer, konstruktion, läckageidentifieringstekniker och spillkontroll. - Tankkomponenternas botten, skal och tak
Inspektioner av tankkomponenter måste inkludera radiografi, magnetisk flödesskanning, vakuumlåda, spårgas, visuell, ultraljud (punkt), ultraljud (scan), flytande penetreringsmedel, penetrerande olja och magnetiska partiklar. - Tankstrukturens botten, skal och tak
Tankkonstruktionerna måste klara minsta återstående tjocklek, minsta erforderliga tjocklek och maximal korrosionshastighet. Det gör att API 653 även inkluderar svetskrav för fältuppförda tankar. - Avvecklingsutvärderingar
Undersökningen fokuserar på hur tanken sätter sig i marken. API 653 bedömer följande faktorer: ur plan, stel kroppslutning, enhetlig, skåltyp, kantsättning och lokaliserade dispersioner.
Hur ofta är API 653 (lagringstank) inspektion?
En certifierad API 653-inspektör måste utvärdera tankens tillstånd och avgöra om den är lämplig för pågående drift. Det finns två typer av inspektioner av ackumulatortank ovanjord - intern och extern. API 653 extern inspektion måste göras vart femte år. Detta intervall kan förlängas om ägaren väljer att göra en bedömning av ultraljudstjocklek (UT).
API specificerar inte UT-metoden, men automatiserade UT-tekniker (AUT) kan producera korrekta data för att bestämma korrosionshastigheten. Inspektionsintervallet kan förlängas upp till 15 år om korrosionshastigheten är känd. Annars finns det kvar vart femte år.
Med tanke på hur viktigt underhåll av lagringstankar är, har API 653-certifieringsprogram för lagringsinspektör ovanjord blivit en av de mest populära certifieringarna. En besiktningsman med API 653-certifiering bör ha omfattande kunskaper om tankinspektion och reparation och måste uppfylla de kvalifikationer som anges i API Standard 653, som gäller för tankinspektion, reparation, ändring och ombyggnad.
Förbered din API 653-certifiering genom att anmäla dig till specificerad API 653-utbildning. Med en blandning av föreläsningar, fallstudier och diskussioner kan API 653-utbildning av PetroSync hjälpa dig att förvärva teoretiska och praktiska färdigheter inom området ovanjordiska lagringstankar som lätt kan tillämpas på ditt jobb. Registrera dig idag och ta din karriär till nästa nivå.
Hur ofta är API653 (Lagringstank) Intern inspektion?
De interna inspektionerna av API 653 krävs vart tionde år, men intervallet kan bli kortare baserat på olika faktorer, inklusive tankens ålder, service och korrosionshastigheter. API 653-inspektörer utför sedan icke-förstörande testningstekniker (NDT) som består av följande:
- Magnetisk partikeltestning (MPT)
- Röntgenundersökning (RT)
- Liquid Penetrant Testing (LPT)
Alla tester tillsammans hjälper till att identifiera eventuella skador, sprickor eller korrosion som kan utgöra en risk för tankens användbarhet. Ytterligare reparationer och modifieringar som följer API 653-standarderna måste göras om några defekter upptäcks.
Är Monthly API 653(Lagringstank) InspektionObligatorisk?
Utöver den erforderliga femåriga externa inspektionen och 10-åriga interna inspektionen, rekommenderas månatlig bedömning enligt API 653 att göras av platsägaren eller operatörerna. Dessa månatliga utvärderingar är till för en regulator att granska. Eventuella tankfel kan upptäckas tidigare genom att bedöma tankens totala tillstånd så omfattande som möjligt.
Hur reglerar API 653 återuppbyggnaden av lagringstanken?
Ovanjordiska lagringstankar (AST) kan bli föremål för omlokalisering eller rekonstruktion av olika skäl. API 653-standarderna reglerar också kraven för design, konstruktion och inspektion av tanken som placeras på den nya platsen eller efter ombyggnad. Tanken måste uppfylla gällande standarder för API 653, där fundamentet måste klara sin vikt och installeras på lämplig jord eller stenar.
Hur reglerar API 653 reparation eller förändring av lagringstanken?
API 653 tar också upp reparation och ändring av AST:er. Allt reparationsarbete som utförs på en tank måste stå under överinseende av API-certifierad inspektör eller en erfaren tankingenjör. Avsnitt 9 i API 653 beskriver de riktlinjer som en certifierad inspektör måste följa när han utför uppgifter som att ta bort eller byta skalplåtsmaterial, installera en dörrplåt, reparera eller installera en ny tankbas och andra relaterade uppgifter.
Vilka är API 653 (lagringstank) undersökningskrav?
För att vara berättigad till API 653-provet måste en kandidat uppfylla något av följande krav:
- Kandidatexamen eller högre inom ingenjörsvetenskap eller teknik: minst ett års erfarenhet av att övervaka eller utföra inspektionsaktiviteter som beskrivs i API 653.
- 2-årig Associate's degree eller certifikat inom ingenjörsvetenskap eller teknik: måste ha minst två års erfarenhet av konstruktion, tillverkning, reparation, drift eller inspektion av tryckkärl, med ett år av den tiden till att övervaka eller utföra inspektionsaktiviteter som beskrivs i API 653.
- En gymnasieexamen eller motsvarande: minst tre års erfarenhet av konstruktion, tillverkning, reparation, drift eller inspektion av tryckkärl, med ett år av den tiden till att övervaka eller utföra inspektionsaktiviteter som beskrivs i API 653.
- Ingen formell utbildning: minst fem års erfarenhet av konstruktion, tillverkning, reparation, drift eller inspektion av tryckkärl, med ett år av den tiden till att övervaka eller utföra inspektionsaktiviteter som beskrivs i API 653.
API 653-certifiering är inte begränsad till tankinspektörer, ingenjörer och arbetsledare som är ansvariga för att säkerställa säkerheten och integriteten hos AST:er. Underhålls- och driftpersonal, maskiningenjörer och korrosionsingenjörer kan också ta denna certifiering. Även om det inte krävs enligt lag, begärs API 653-certifiering ofta av arbetsgivare och tillsynsmyndigheter som bevis på expertis.
