ASME cov lej rau cov khoom siv hluav taws xob
ASME yog American Society of Mechanical Engineers, nrhiav tau nyob rau hauv 1880. Lawv ua hauj lwm nyob rau hauv ntau yam sectors thiab tau tsim ntau tshaj 500 txawv qauv rau manufacturing. Qhov no suav nrog cov lej rau boilers thiab cov hlab ntsha siab, nyob rau hauv uas cov cua sov exchangers poob.
Dab tsi yog ASME cov lej?
ASME's International Boiler thiab Pressure Vessel Code (BPVC) muaj 11 ntu, nrog ntau dua 15 ntu thiab sub-sections. Nws yog ib daim ntawv qhia uas npog ntau yam ntawm cov boilers sib txawv thiab cov hlab ntsha siab.
Saib ASME daim ntawv qhia ntawm International Boiler thiab Pressure Vessel Code.
Ntu uas siv rau feem ntau cov khoom siv hluav taws xob yog ASME VIII.
Nws suav nrog cov cai thiab cov lus pom zoo rau:
- Cov ntaub ntawv (ASME II-A, B, C, D)
- Tsim (ASME VIII Div I & Div II)
- Kev Ntsuas & Kev Ntsuas (ASME V)
- Vuam (ASME IX)
Cov lis dej num npog yuav luag txhua qhov chaw ntawm kev tsim kho cov khoom siv hluav taws xob. Qhov tsuas yog qhov tshwj xeeb yog hom kev pabcuam thauj khoom (tshwj tsis yog lub siab) thiab thermal tsim. Txhua lub chaw tsim khoom siv hluav taws xob yuav siv nws tus kheej cov qauv thermal los tsim cov khoom siv hluav taws xob.
Koj tuaj yeem nyeem cov ntaub ntawv ntau ntxiv txog yuav ua li cas cov khoom siv hluav taws xob tau tsim hauv peb qhov blog.
European Standards
Muaj ntau yam kev hloov pauv hluav taws xob ntxiv siv nyob rau hauv European manufacturing.
PIB 5500
PD 5500: 2021 tus qauv yog rau cov tsis muaj hluav taws kub, fusion-welded siab hlab ntsha. Zoo li lwm cov qauv zoo sib xws, nws suav nrog cov kev qhia tshwj xeeb ntsig txog kev tsim, tsim, thiab tshuaj xyuas cov hlab ntsha, nrog rau cov khoom siv hluav taws xob.
Nws yog yav dhau los tus qauv British hu ua BS 5500.
EN 13445 Cov Qauv
BS EN 13445 series suav nrog txhua qhov chaw ntawm European siab cov hlab ntsha cov qauv. Nws tau sau mus nrog PED.
Ib tug tshiab version tau tso tawm nyob rau hauv 2021 thiab npog:
- Cov ntaub ntawv dav dav ntawm kev tsim thiab kev tsim khoom
- Khoom siv
- Tsim
- Fabrication
- Kev tshuaj xyuas thiab kuaj
- Cam khwb cia hlau hlab ntsha
- Aluminium
- Nickel
CODAP
CODAP (Code de construction des Appareils à Pression) yog Fab Kis txoj cai rau kev tsim cov khoom siv hluav taws xob tsis muaj hluav taws xob, xws li cov khoom siv hluav taws xob. Zoo ib yam li lwm cov qauv siv hluav taws xob sib txawv thoob ntiaj teb, CODAP code ua kom ntseeg tau tias cov khoom siv hluav taws xob muaj kev nyab xeeb thiab zoo.
Kev cai
Cov Khoom Siv Hluav Taws Xob Kev Nyab Xeeb Kev Nyab Xeeb 2016 (PER)
Cov no yog UK tsuas yog cov kev cai uas tau pib siv thaum UK tawm ntawm European Union. Lawv siv rau kev tsim thiab tsim cov khoom siv siab tshaj qhov siab tshaj plaws tso cai ntawm 0.5 bar. Nws kuj tseem siv tau rau cov khoom siv ntxiv uas siv rau hauv cov cuab yeej siv siab uas haum rau qhov kev ua haujlwm no, xws li kev hloov pauv kev nyab xeeb.
Cov Txheej Txheem Kev Nyab Xeeb Kev Ruaj Ntseg Ua Haujlwm ua ke nrog cov qauv tsim rau PER.
Cov Lus Qhia Cov Khoom Siv Siab
Cov Lus Qhia Cov Khoom Siv Siab (PED) yog qhov yuav tsum tau ua nyob rau hauv European Union thaum tsim cov khoom siv siab, lossis muag rau hauv EU. Nws siv rau cov khoom siv nrog qhov siab tshaj plaws tso cai siab tshaj 0.5 bar ntsuas.
PED yog tsim los txhim kho thiab ua kom cov txheej txheem kev cai lij choj kom lub chaw tsim khoom tsis tas yuav dhau los ntawm tsoomfwv kev pom zoo hauv txhua lub tebchaws ntawm EU.
Thaum koj ua tau raws li qhov yuav tsum tau ua ntawm Cov Lus Qhia, koj tuaj yeem siv CE kos rau cov khoom.
CE vs UKCA cim
Qhov txawv ntawm CE thiab UKCA cov cim tsuas yog seb cov khoom puas tau pom zoo muag hauv EU lossis UK.
CE marking yog siv rau ntau yam khoom lag luam hauv Kev Lag Luam Ib Leeg hauv European Economic Area (EEA). Yog tias ib yam khoom muaj CE cim, nws qhia tau tias cov khoom tau raug soj ntsuam thiab ua tau raws li cov qauv kev nyab xeeb, kev noj qab haus huv thiab kev tiv thaiv ib puag ncig hauv EU.
Lub UK tsis yog ib feem ntawm EU lawm thiab, txij li xyoo 2021, siv UKCA - txawm hais tias feem ntau cov khoom tseem tuaj yeem siv CE mus txog rau xyoo 2023 los pab rau kev hloov pauv. Nws sawv cev rau UK Kev Ntsuam Xyuas Kev Ua Raws Cai thiab siv rau cov khoom muag hauv Great Britain.
Cov kev xav tau ntawm ob qho tib si yog ntau yam zoo ib yam, xws li cov txheej txheem kev ntsuas kev sib haum xeeb thiab cov qauv uas tuaj yeem siv los ua kom pom kev sib haum xeeb.
NORSOK
NORSOK cov qauv tsim los ntawm Norwegian roj av kev lag luam thiab yog qhov tseem ceeb rau kev tsim cov khoom siv hluav taws xob los muag hauv Norway.
Muaj ntau yam qauv hauv NORSOK. Piv txwv li, R-001 piav qhia txog cov kev xav tau ntawm cov cuab yeej siv tshuab, suav nrog cov cuab yeej siv siab xws li cov khoom siv hluav taws xob. M-001 piav qhia txog kev xaiv cov khoom, thiab P-001 piav qhia txog tus txheej txheem tsim.
TEMA Standards
TEMA cov qauv yog kab tias feem ntau siv cov khoom siv hluav taws xob sib txawv rau kev tsim cov plhaub thiab cov raj kub hloov cov qauv tsim. TEMA yog tus
Tubular Exchanger Manufacturers Association, ib lub koom haum ntawm manufacturers ntawm plhaub thiab raj kub exchangers. Qhov no yuav ntxiv rau Txoj Cai Kev Lag Luam lossis yog thawj txoj cai hu ua thaum tsis muaj kev lag luam Code raug siv los tsim cov khoom siv hluav taws xob.
TEMA tau tsim cov txheej txheem los xyuas kom meej qhov zoo ntawm lub plhaub thiab lub raj cua kub exchanger tsim thiab tsim khoom.
Feem ntau lub plhaub thiab lub raj xa hluav taws xob tsim tawm thoob ntiaj teb tau ua tiav raws li TEMA cov qauv. TEMA Standard suav nrog 10 ntu uas suav nrog cov npe nkag mus rau lub cev ntawm cov kua dej siv hauv cov khoom siv hluav taws xob.
API
API cov qauv muaj feem xyuam rau kev tsim khoom thiab cov khoom siv rau kev lag luam roj thiab roj. Ob tus qauv API uas feem ntau cuam tshuam rau kev tsim cov khoom siv hluav taws xob sib txawv yog API 12 thiab API 560 (Cov Cuab Yeej Hluav Taws Xob rau Kev Pabcuam General Refinery) - ob qho tib si peb siv ntawm GNEE.
- API 660 yog siv rau ntawm Plhaub thiab Tube Thaum tshav kub kub Exchangers
- API 661 yog siv rau ntawm Cua -txias Thaum tshav kub kub Exchangers / Cua blast / Fin Ntxuam Coolers
- API 560 yog siv rau cua preheaters, piv txwv li.
ISO Certification
Cov chaw tsim khoom ntawm cov khoom siv hluav taws xob yuav tsum tau lees paub nrog ISO 9001: 2015. Qhov no ua kom zoo ib yam ntawm cov khoom siv hluav taws xob sib txawv.
Ob qho ntawm peb qhov chaw tsim khoom ntawm Sterling TT (hauv Aylesbury thiab Birmingham) tau lees paub ISO 9001: 2015.
Sterling TT yog raws li nyob rau hauv UK tab sis tsim thiab manufactures bespoke tshav kub exchangers thoob ntiaj teb. Peb cov khoom siv hluav taws xob ua raws li cov qauv thoob ntiaj teb, thiab peb muaj kev paub ua haujlwm rau cov qauv thoob ntiaj teb. Peb tsis tu ncua ua haujlwm nrog NKK (Nyiv), ABS (US) thiab DNV (Norway) los ua ob peb lub npe.
