Uphahla Olundizayo Lwangaphakathi Vs Uphahla Olundizayo Lwangaphandle
Kwadalwa ngo Ngokwamukisa
Uphahla Oluntantayo Lwangaphakathi Vs Uphahla Oluntantayo Lwangaphandle
Uphahla Oluntantayo Lwangaphakathi Vs Uphahla Oluntantayo Lwangaphandle kunqunywa umkhiqizo ogciniwe, ububanzi bethangi, umthetho wokukhishwa kwegesi kanye nezindleko zomjikelezo wokuphila - hhayi ukuthanda okujwayelekile. Inketho ngayinye iyawina endaweni echaziwe.
Yini Inketho Ngayinye
Uphahla oluntantayo lwangaphakathi kanye nophahla oluntantayo lwangaphandle luxazulula izinkinga ezihlangana kodwa ezingafani. Isinyathelo sokuqala ukubiza umsebenzi womsebenzisi: ukulawula umhwamuko, ukuvalwa kwesikhala sengqondo, umkhawulo wezindleko noma ukufinyelela kokunakekela, ngoba impendulo efanele iyashintsha ngomsebenzi.
Imigomo Yesinqumo
· Ukuguquguquka komkhiqizo ogciniwe kanye nephuzu lokushisa.
· Ububanzi bethangi kanye nohlobo lwegobolondo (olugxilile noma oluvulekile phezulu).
· Ikhodi yokukhishwa komoya kanye nekhodi yomlilo esebenzayo.
· Izindleko zomjikelezo wokuphila uma ziqhathaniswa nezindleko zokuqala.
· Ukufinyelela kokunakekela kanye nesikhathi sokuhlola.
Lapho i-Internal floating roof Ifaneleka Khona
I-Internal floating roof iyathandwa lapho inzuzo yayo ethile ihambisana nomsebenzi. Ayikhethwa ngokuzenzakalela; ukushintshana kufanele kubhalwe ukuze umhloli wakamuva abone ukuthi kungani enye indlela yenqatshiwe.
Lapho i-External floating roof Ifaneleka Khona
I-External floating roof ifaneleka emkhakheni ohambisanayo. Ukuyisebenzisa ngaphandle kwalowo mkhakha kudala izinkinga zezindleko noma zokuhambisana nezimiso ezifihlwa ukukhetha okujwayelekile.
Indlela Yokukhetha Nokuklama
Indlela ephindwayo igcina ukukhetha kuvikelekile kumathangi afanayo:
1. Bhala umsebenzi womsebenzisi ngomusho owodwa ngaphambi kokuqhathanisa uphahla oluntantayo lwangaphakathi kanye nophahla oluntantayo lwangaphandle.
2. Bhala ukuguquguquka, ububanzi kanye nekhodi ebopha ukukhetha.
3. Hlunga uphahla oluntantayo lwangaphakathi kanye nophahla oluntantayo lwangaphandle ngokumelene nezindleko zomjikelezo wokuphila, hhayi intengo yokuthenga.
4. Rekhoda inketho enqatshiwe (uphahla oluntantayo lwangaphakathi noma uphahla oluntantayo lwangaphandle) kanye nesizathu, ukuze kuhlolwe.
5. Qinisekisa ukukhethwa ngokuhambisana nohlelo lokuhlola nokunakekela.
Uhlaka Lokulinganisa (Oluyisibonelo, Hhayi Isibalo Sephrojekthi)
Sebenzisa lobu budlelwano ukuhlola umjikelezo wokuphila we-Internal Floating Roof Vs External Floating Roof ngaphambi kokuzibophezela enombolweni:
Izindleko zomjikelezo wokuphila ≈ izindleko zokuqala + (ukulungisa + amandla + isikhathi sokuphazamiseka) phakathi nempilo yesevisi; qhathanisa emkhakheni ofanayo.
Konke okokufaka okusohlwini lokuhlolwa komjikelezo wempilo kwe-Internal Floating Roof Vs External Floating Roof ngezansi kuyizibonelo - kukhombisa indlela kuphela futhi akusona isibalo esikalwe kusuka kunoma yimuphi umsebenzi wangempela wokuhlolwa komjikelezo wempilo kwe-Internal Floating Roof Vs External Floating Roof; shintsha idatha yendawo eqinisekisiwe kuqala.

Ikhadi lokulinganisa lesinqumo
Ukuklama okulula kuphoqa ukuthi ukukhetha kulandele umsebenzi. Nikeza amaphuzu kumugqa ngamunye we-Internal floating roof kanye ne-External floating roof; inketho enqoba imigqa ebophayo (umkhiqizo, ububanzi, ikhodi) iyona elungile ngisho noma yehlulwa ngentengo. Izisindo ezingezansi ziyizibonelo futhi kufanele zisethwe kabusha kumsebenzi wangempela.

Lapho Lokhu Kuqhathanisa Kusetshenziswa Kabi
Ukukhethwa kophahla oluntantayo lwangaphakathi uma kuqhathaniswa nophahla oluntantayo lwangaphandle kusetshenziswa kabi uma kwenziwa ngokwentengo kuphela, uma ukuguquguquka komkhiqizo nobubanzi bethangi kungashiwo kuqala, noma uma inketho enqatshiwe ingabhalwanga. Ngaphandle kwemikhawulo yayo, inketho 'elahlekelayo' ephepheni ingaba ukuphela kokukhetha okuhambisana nomthetho empeleni, ngakho umsebenzi - hhayi ukuqhathanisa okuyisihloko - kufanele kunqume.
Ukushintshana Nezingozi
· Uma uphahla oluntantayo lwangaphakathi lusetshenziswa ngaphandle kwemikhawulo yalo, ingozi enkulu iwukuthi Kokophahla oluntantayo lwangaphakathi uma kuqhathaniswa nophahla oluntantayo lwangaphandle, igebe lesivalo nokulingana kwedekhi kubangela ukulahleka komhwamuko; izivalo eziphindwe kabili nokulingana okuqinile kuyakunciphisa.
· Uma uphahla oluntantayo lwangaphandle lusetshenziswa ngaphandle kwemikhawulo yalo, ukulawulwa kokugqwala nokufinyelela kungase kuphazamiseke.
· Noma yikuphi okukhethiwe, isigaba sokufakwa kwezimpawu esingalungile sivumela imililo ye-Rim-seal ukuthi iqale ekukhishweni kukagesi omile, umbani noma umsebenzi oshisayo; isigaba sokufakwa kwezimpawu, ukuxhumanisa kanye nezinhlelo zegwebu kuyalawula ingozi.

· Ukukhetha ngomkhuba esikhundleni somkhiqizo nobubanzi.
· Ukucaphuna izinga ngaphandle kokuhlola ububanzi baso.
· Ukweqa irekhodi lenketho enqatshiwe (kungani kungenjalo uphahla oluntantayo lwangaphandle).
Ukusekelwa Kobunjiniyela Nezinyathelo Ezilandelayo
Ku-Internal Floating Roof Vs External Floating Roof, hlinzeka ngomkhiqizo ogciniwe, ukugxila, izinga lokushisa, ingcindezi yomhwamuko, ikhodi yokuklama, ububanzi bethangi, ivolumu edingekayo kanye nokushintshwa. Unjiniyela ofanelekile bese ekhetha uhlobo lwophahla lwe-Internal Floating Roof Vs External Floating Roof, isigaba sedekhi nesiceli kanye nesisekelo sokuhlola esikhundleni sesiphakamiso esibanzi.
Imibuzo Evame Ukubuzwa
1. Uphahla oluntantayo lwangaphakathi noma uphahla oluntantayo lwangaphandle - yikuphi okufanele ngikukhethe?
Khetha ngomkhiqizo ogciniwe, ububanzi bethangi kanye nekhodi esebenzayo. Ithebula lokuqhathanisa lihlobanisa ngakunye nesigaba salo; ngaphandle kwaleso sigaba enye indlela ayilungile, ayishibhile.
2. Ingabe izindleko ziyayinquma?
Izindleko zokuqala zodwa azikunqumi; izindleko zomjikelezo wokuphila, impilo yokufakwa kwezimpawu kanye nokufinyelela kokuhlola ngokuvamile kudla amandla ngaphezu kwentengo yokuthenga.
3. Ngingashintsha kamuva?
Ukuguqulwa kungenzeka kwezinye izimo (isibonelo, uphahla olungagxili kuphahla lwangaphakathi oluntantayo) kodwa kudinga ukuhlolwa kabusha kwegobolondo, ukufakwa kwezimpawu kanye nokukhipha umoya.
4. Yimiphi imigomo esebenzayo?
API 650, EN 14015 kanye ne-API 2000 ngokufanele; imithetho yokukhishwa kwezinto ezingcolisayo njenge-EPA Benzene NESHAP lapho i-benzene ikhona ku-Internal Floating Roof Vs External Floating Roof.
5. Iyiphi iphutha elikhulu kakhulu?
Ukukhetha ngomkhuba noma ngentengo nokunganaki ukuguquguquka komkhiqizo kanye nobubanzi obubeka ngempela imfuneko.
6. Ngiqinisekisa kanjani ukukhetha?
Qinisekisa okokufakwayo kwe-Internal Floating Roof Vs External Floating Roof - idatha yomkhiqizo, ububanzi, ukushintshwa nokhodi - bese uthola unjiniyela ukuthi ahlole uhlobo lwedekhi, isigaba sesiliva kanye nokubekezelelana.
7. Isinqumo sirekhodwa kuphi?
Encazelweni kanye ne-Unique Value Brief ukuze inketho enqatshiwe kanye nesizathu sayo kuhlolwe.
I-Internal Floating Roof Vs External Floating Roof kunqunywa umkhiqizo ogciniwe othile, ingcindezi yawo yomhwamuko, izinga lokushisa, indawo yokugqwala kanye nekhodi esebenzayo - hhayi umkhuba. Qala ezimweni zokusebenza, uzihlanganise nohlobo olulungile lwe-floating-roof kanye nekilasi le-seal, bese uqinisekisa ukubekezelelana kwe-deck, i-seal kanye ne-shell ngokumelene nezinga elikhethiwe. Lapho kudingeka khona izilinganiso eziqondene nephrojekthi, inani lamathangi noma umthamo, qinisekisa lokho ngokumelene nerekhodi lethangi eliqinisekisiwe ngaphambi kokuqedela ukucaciswa.
