Cov yeeb nkab dub feem ntau zoo dua thiab yog cov qauv kev xaiv rau sab hauv tsev cov pa roj carbon monoxide thiab propane kab. Thaum cov yeeb nkab galvanized tuaj yeem siv rau hauv cov xwm txheej tshwj xeeb, nws feem ntau txwv los yog txwv tsis pub los ntawm cov cai hauv zos rau kev ua haujlwm hauv cov pa roj.
Vim li cas cov yeeb nkab dub ua haujlwm rau roj?
Cov yeeb nkab dub (feem ntau hu ua cov yeeb nkab hlau dub) yog lub hom phiaj- ua rau roj.
- Uncoated carbon steel nrog nyias dub zeb oxide txheej, tsis muaj zinc plating.
- Threaded pob qij txha kaw kev ntseeg siab nrog cov roj yeeb nkab dope; tsis muaj flaking internal txheej.
- Kev kub siab ua haujlwm, muaj zog, tsoo- tiv taus, kev nyab xeeb hluav taws zoo heev rau cov kab roj.
- Kev pab lub neej ntev nyob hauv tsev, universal code pom zoo rau cov nkev thiab propane.
- Tsis muaj cov khoom uas tuaj yeem ua rau cov roj regulators, valves, lossis burners.
Vim li cas galvanized yeeb nkab tsis pom zoo siv rau roj?
Galvanized yeeb nkab muaj tuab zinc tiv thaiv txheej sab hauv thiab tawm:
Zinc flakes tev tawm hauv cov yeeb nkab thaum cov roj ntws, kev co tshwm sim, lossis kub hloov pauv. Cov pob zeb zinc nyuaj no taug kev mus rau hauv qab dej thiab jam gas regulators, clog valve orifices, thiab thaiv cov khoom siv hluav taws xob - tsim cov roj ntws tsis ua hauj lwm thiab hluav taws kub / tawg.
Zinc reacts nrog noo noo nyob rau hauv cov roj kab los tsim cov deposits uas nqaim cov yeeb nkab bore thiab txo cov roj mov siab.
Ib qho tshwj xeeb (Qhov twg Galvanized zoo dua)
International Fuel Gas Code (IFGC): Tsis txwv tsis pub galvanized yeeb nkab. Nws tso cai rau nws, yog tias cov roj tsis muaj ntau tshaj 0.3 nplej ntawm hydrogen sulfide ib 100 cubic feet (uas niaj hnub siv roj av feem ntau tsis muaj).
Thaum twg Galvanized yeeb nkab siv rau roj?
Tib qhov chaw uas cov yeeb nkab galvanized feem ntau suav hais tias yog qhov zoo tshaj plaws yog sab nraum zoov, saum av.
Galvanized yeeb nkab tuaj yeem tso cai rau qee qhov kev txiav txim, tshwj xeeb tshaj yog rau:
- Cov kav dej sab nraum zoov raug cov dej noo
- Corrosive ib puag ncig
- Daim ntawv thov kev lag luam tshwj xeeb
Qhov zoo ntawm Galvanized yeeb nkab
- Zoo dua tiv thaiv atmospheric corrosion
- Lub neej ntev dua nyob rau hauv cov av ntub lossis sab nraum zoov
Qhov tsis zoo
- Cov khoom siv ntau dua
- Cov cai hauv zos yuav txwv tsis pub nws siv rau cov roj siv hluav taws xob
- Ntxiv dag zog rau threading vim zinc txheej
Dab tsi yog cov yeeb nkab zoo tshaj plaws rau cov kab hluav taws xob ntuj?
Rau feem ntau ntawm cov khoom siv roj av hauv tsev: Cov yeeb nkab dub yog qhov kev xaiv zoo dua vim tias nws yog tus nqi - siv tau, tau txais dav, thiab tshwj xeeb rau kev pabcuam roj.
Rau cov kav dej sab nraum zoov hauv qhov chaw corrosive: Galvanized yeeb nkab tuaj yeem muab kev tiv thaiv corrosion ntxiv, yog tias cov kev cai hauv zos tso cai rau nws siv.
Txawm li cas los xij, los ntawm kev pom zoo thiab kev lag luam, cov yeeb nkab dub tseem yog cov yeeb nkab uas feem ntau tau teev tseg rau cov tshuab hluav taws xob, thaum cov yeeb nkab galvanized feem ntau tshwj tseg rau cov xwm txheej uas xav tau kev txhim kho corrosion thiab kev pom zoo code tau lees paub.
