yintoni umgangatho we-DOT we-lpg cylinder?

I-DOT imele iSebe lezoThutho eUnited States, kwaye ibhekisela kwiseti yemigaqo nemigangatho elawula ukuyilwa, ukwakhiwa, kunye nokuhlolwa kwezixhobo ezahlukeneyo ezinxulumene nezothutho, kuquka iisilinda zeLPG. Xa kubhekiswa kwi-LPG cylinder, iDOT ikholisa ukunxulumana nemigaqo ethile yeDOT esebenza kwiisilinda ezisetyenziselwa ukugcina okanye ukuthutha igesi yepetroleum engamanzi (LPG).

Nalu ucazululo lwendima yeDOT ngokunxulumene neesilinda zeLPG:

1. Iimpawu zeDOT zeeSilinda
I-DOT ibeka imigangatho yokwenziwa, ukuvavanya, kunye nokuleyibheli kweesilinda ezisetyenziselwa ukugcina izinto ezinobungozi, kubandakanywa ne-LPG. Le migaqo ijolise ngokukodwa ekuqinisekiseni ukhuseleko ngexesha lokuthutha kunye nokuphathwa kweesilinda zegesi.

Iisilinda ezivunyiweyo ze-DOT: Iisilinda ze-LPG ezilungiselelwe ukusetyenziswa kunye nokuthutha e-US kufuneka zihlangabezane neenkcukacha ze-DOT. Le mibhobho isoloko igximfizwa ngoonobumba “DOT” elandelwa yinombolo ethile ebonisa uhlobo kunye nomgangatho we-cylinder. Ngokomzekelo, i-DOT-3AA cylinder ngumgangatho weesilinda zensimbi ezisetyenziselwa ukugcina iigesi ezixinzelelweyo njenge-LPG.
2. I-DOT Cylinder Marking
I-cylinder nganye evunyiweyo ye-DOT iya kuba neempawu ezigxininiswe kwintsimbi enika ulwazi olubalulekileyo malunga neenkcukacha zayo, kuquka:

Inombolo ye-DOT: Oku kubonisa uhlobo oluthile lwe-cylinder kunye nokuthotyelwa kwayo nemigangatho ye-DOT (umz., i-DOT-3AA, i-DOT-4BA, i-DOT-3AL).
Inombolo yothotho: Isilinda ngasinye sinesichongi esisodwa.
Uphawu loMenzi: Igama okanye ikhowudi yomenzi owenze isilinda.
Umhla woVavanyo: Iisilinda kufuneka zivavanyelwe rhoqo ukhuseleko. Isitampu siya kubonisa umhla wokugqibela wokuvavanya kunye nomhla wokuvavanya olandelayo (ngokuqhelekileyo yonke iminyaka eyi-5-12, kuxhomekeke kuhlobo lwesilinda).
Uxinzelelo loxinzelelo: Uxinzelelo oluphezulu apho i-cylinder yenzelwe ukusebenza ngokukhuselekileyo.
3. Imigangatho ye-DOT Cylinder
Imimiselo ye-DOT iqinisekisa ukuba iisilinda zakhiwe ukuze zimelane ngokukhuselekileyo noxinzelelo oluphezulu. Oku kubaluleke ngakumbi kwi-LPG, egcinwa njengolwelo phantsi koxinzelelo ngaphakathi kweesilinda. Imigangatho yeDOT igubungela:

Izinto eziphathekayo: Iisilinda kufuneka zenziwe ngezinto ezomeleleyo ngokwaneleyo ukumelana noxinzelelo lwegesi ngaphakathi, njengentsimbi okanye i-aluminiyam.
Ukutyeba: Ubukhulu beendonga zentsimbi kufuneka buhlangabezane neemfuno ezithile zamandla kunye nokuqina.
Iindidi zeValve: I-valve yesilinda kufuneka ihambelane neenkcukacha ze-DOT ukuqinisekisa ukuphathwa ngokufanelekileyo kunye nokhuseleko xa i-cylinder ixhunyiwe kwizixhobo zombane okanye isetyenziselwa ukuthutha.
4. Ukuhlolwa noVavanyo
Uvavanyo lwe-Hydrostatic: I-DOT idinga ukuba zonke iisilinda ze-LPG zifumana uvavanyo lwe-hydrostatic rhoqo emva kweminyaka emi-5 okanye eyi-10 (kuxhomekeke kuhlobo lwesilinda). Olu vavanyo lubandakanya ukuzalisa isilinda ngamanzi kwaye uyicinezele ukuqinisekisa ukuba inokubamba ngokukhuselekileyo igesi kuxinzelelo olufunekayo.
Ukuhlolwa Okubonwayo: Iisilinda kufuneka kwakhona zijongwe ngokubonakalayo umonakalo onje ngomhlwa, izibonda, okanye iintanda phambi kokuba zisetyenziswe.
5. DOT vs. Eminye iMigangatho yeHlabathi
Nangona imimiselo ye-DOT isebenza ngokukodwa kwi-US, amanye amazwe anemigangatho yawo yeesilinda zegesi. Umzekelo:

I-ISO (I-International Organisation for Standardization): Amazwe amaninzi, ngakumbi eYurophu nase-Afrika, alandela imigangatho ye-ISO yokwenziwa nokuthutha iisilinda zegesi, ezifana nemigangatho ye-DOT kodwa zinokuba neeyantlukwano ezithile zengingqi.
I-TPED (I-Transportable Pressure Equipment Directive): Kwi-European Union, i-TPED ilawula imigangatho yokuthutha iinqanawa zoxinzelelo, kuquka iisilinda ze-LPG.
6. Iingqwalasela zoKhuseleko
Ukuphatha ngokufanelekileyo: Imimiselo ye-DOT iqinisekisa ukuba iisilinda zenzelwe ukuphathwa ngokukhuselekileyo, ukunciphisa ingozi yeengozi ngexesha lokuthutha okanye ukusetyenziswa.
Iivalve zoNcedo oluNgxamisekileyo: Iisilinda kufuneka zibe neempawu zokhuseleko ezifana neevalvu zoncedo loxinzelelo ukuthintela ukunyanzeliswa koxinzelelo oluyingozi.
Isishwankathelo:
Imimiselo ye-DOT (iSebe lezoThutho) iqinisekisa ukuba iisilinda ze-LPG ezisetyenziswa e-US zihlangabezana nemigangatho ephezulu yokhuseleko kunye nokuqina. Le mimiselo ilawula ukwakhiwa, ukuleyibhile, ukuhlolwa, kunye nokuvavanya iisilinda zegesi ukuqinisekisa ukuba ziyakwazi ukuqulatha ngokukhuselekileyo igesi enoxinzelelo ngaphandle kokusilela. Le migangatho ikwanceda ukukhokela abavelisi kunye nabasasazi ekuveliseni nasekusasazeni iisilinda ezikhuselekileyo, ezithembekileyo kubathengi.

Ukuba ubona uphawu lwe-DOT kwi-cylinder ye-LPG, oko kuthetha ukuba isilinda sakhiwe kwaye savavanywa ngokwale migaqo.
