Cov lus nug nquag
Q1: NFPA 58 yog dab tsi thiab vim li cas nws thiaj li tseem ceeb rau kuv qhov system propane?
NFPA 58 (lub Liquefied Petroleum Gas Code) yog tus qauv kev lag luam tseem ceeb tswj kev teeb tsa, khaws cia, thiab siv cov propane hauv Tebchaws Meskas, thiab nws tseem ceeb rau koj qhov system propane vim tias nws tau txais kev cai lij choj hauv ntau lub xeev thiab hauv nroog - txhais tau tias koj qhov kev teeb tsa propane yuav tsum ua raws li nws lossis kev ua txhaum cai ntawm lub ntsej muag. NFPA 58 npog txhua yam los ntawm qhov deb tsawg kawg nkaus ntawm cov tso tsheb hlau luam thiab cov tsev (10 ko taw rau cov chaw nyob hauv tsev), mus rau qhov kev faus qhov tob rau cov tso tsheb hlau luam hauv av (12-24 ntiv tes tsawg kawg nkaus), rau cov khoom siv rau cov kav dej thiab cov khoom siv sib txuas, rau qhov yuav tsum tau ua rau lub tank anchoring thiab nyem valve installation. Txoj cai yog tsim los ntawm National Fire Protection Association, lub koom haum tsis muaj txiaj ntsig, thiab tau hloov kho txhua peb lub xyoos los koom nrog cov thev naus laus zis tshiab, cov lus qhia tau kawm los ntawm qhov xwm txheej, thiab txhim kho kev nyab xeeb. Raws li tus neeg siv khoom, koj tsis tas yuav cim NFPA 58, tab sis koj yuav tsum paub tias nws muaj thiab cov kws tshaj lij propane tau tso cai yuav tsum tau nruab thiab pab koj lub cev ua raws li nws. Yog tias koj puas tau nug seb puas ua haujlwm ntawm koj lub propane system puas tau ua tiav, nug koj tus kws kho mob kom paub meej tias kev ua raws li NFPA 58 yog ib lo lus nug tsim nyog thiab tsim nyog - txhua tus kws tshaj lij yuav tuaj yeem piav qhia seb lawv txoj haujlwm ua tau raws li txoj cai.
Q2: Kuv yuav paub li cas yog tias kuv lub tog raj kheej propane ua tau raws li DOT cov qauv?
Koj paub tias koj lub propane lub tog raj kheej ua tau raws li DOT cov qauv yog tias nws muaj DOT specification cim kos rau ntawm dab tshos - feem ntau rau cov neeg siv khoom propane tso tsheb hlau luam yog "DOT 4BW" - thiab yog tias nws nyob hauv nws lub sijhawm tam sim no raws li qhia los ntawm hnub tas sij hawm stamped. Daim ntawv qhia DOT qhia koj tus qauv twg lub tog raj kheej tau tsim los ua kom tau raws li, thiab nws yog cov chaw tsim khoom pov thawj tias lub tog raj kheej tau tsim, tsim, thiab sim tswj cov propane ntawm qhov kub thiab txias nws yuav ntsib nyob rau hauv ib txwm siv. Hnub tas sij hawm (stamped nyob rau hauv lub hli- xyoo format) qhia rau koj thaum lub sij hawm requalification tam sim no tas sij hawm - lub tog raj kheej tsis tuaj yeem rov qab raws li txoj cai tom qab hnub no yam tsis tau dhau qhov kev tshuaj ntsuam xyuas. Yog tias koj lub tog raj kheej dhau los ntawm hnub tas sij hawm, nws yuav tsum tsis txhob muab sau los ntawm ib tus neeg xa khoom muaj npe nrov, vim tias tus neeg muag khoom yuav ua txhaum DOT cov khoom siv phom sij thiab yuav raug cai yog tias muaj xwm txheej tshwm sim. Yog tias koj nrhiav tsis tau lossis nyeem DOT cim lossis hnub tas sij hawm ntawm koj lub tog raj kheej, coj lub tog raj kheej mus rau tus kws tshaj lij propane uas tsim nyog lossis hu rau lub tuam txhab lub tog raj kheej nrog tus lej xov tooj los saib nws. Lub tog raj kheej tsis muaj DOT cim tsis raug cai rau kev siv propane thiab yuav tsum tsis txhob muab sau rau hauv ib qho xwm txheej.
Q3: Puas yog cov qauv kev lag luam propane zoo ib yam hauv txhua lub xeev?
Cov qauv kev lag luam Propane tsis zoo ib yam hauv txhua lub xeev - thaum NFPA 58 thiab DOT cov kev cai muab cov ntsiab lus tseem ceeb hauv tsoomfwv, xeev thiab hauv nroog ntxiv lawv tus kheej cov cai, kev hloov kho, thiab kev tswj hwm cov txheej txheem uas tuaj yeem ua rau cov cai sib txawv ntawm ib cheeb tsam mus rau lwm qhov. Feem ntau lub xeev tau txais NFPA 58 nrog qee qhov kev hloov kho, tab sis cov xeev tuaj yeem txwv ntau dua li tus qauv code - qee lub xeev xav tau kev tshem tawm lub tank ntau dua li NFPA 58 qhia, qee qhov muaj cov kev xav tau ntxiv rau kev teeb tsa hauv av thiab kev saib xyuas, thiab qee qhov muaj cov ntawv tso cai tshwj xeeb rau cov kws tshaj lij propane uas nruj dua NFPA 58 kev taw qhia. Xeev propane gas commissions lossis pawg thawj coj saib (hauv xeev uas muaj lawv) tswj hwm cov cai no thiab ua kev soj ntsuam, thiab cov tub ceev xwm hauv zos tswj hwm cov cai hluav taws kub hauv nroog. Qhov no txhais tau hais tias dab tsi raug cai hauv ib lub xeev yuav xav tau cov kauj ruam ntxiv lossis cov cuab yeej sib txawv hauv lub xeev nyob sib ze. Qhov cuam tshuam rau cov neeg siv khoom yog tias koj yuav tsum tau kuaj xyuas nrog koj tus neeg muag khoom propane hauv zos lossis lub xeev propane gas commission kom paub meej cov kev cai tshwj xeeb hauv koj cheeb tsam, tsis yog tso siab rau cov ntaub ntawv dav dav. Koj tus kws tshaj lij propane muaj ntawv tso cai yuav tsum paub txog cov kev cai hauv zos thiab yuav tsum xyuas kom koj lub installation ua tau raws li lawv.
