Ungaqinisekisa kanjani ukuthi ukujiya kwe-zinc kuhlangabezana nezidingo zakho zephrojekthi?
Ngobaipayipi lensimbi,-ukuvikela ukugqwala kwesikhathi eside kuqhutshwai-zinc enamathela ukushuba kanye nenqubo yokugqoka. Indlela efanele yokugaya kufanele ikhethwe ngokuya ngendawo lapho kuzofakwa khona ipayipi.
Ngobaizindawo ezonakalisa kakhulu- njengamaplathifomu angasogwini, izakhiwo ezisogwini noma izindawo zokuchaphaza - sincomakushisa kakhulu-i-dip galvanizingnge enamathela izisindo of500 g/m² nangaphezulu. Lesi singqimba se-zinc esishubile sinikeza ukuphila okuphezulu emkhathini wasolwandle, amajakhethi angasogwini, amapayipi amanzi, amapayipi amapayipi ezindaweni zokuhluza kanye nezinsimbi eziveziwe.
Kuhleloxhumano lokuphakelwa kwamanzi emadolobheni, izintambo zokuvikela umlilo kanye namapayipi avamile ezimbonini, imbobo evamile eshisayo{0}}yediphu engu-300 g/m² ngokuvamile yanele. Leli zinga lokuvikela lilingana nezintambo eziningi zamanzi zikamasipala, amapayipi ezinsiza zokwakha, isifafaza somlilo kanye nezinhlelo zamapayipi amanzi, okuhlinzeka ukuqina okuhle ngezindleko ezifanele.
Kumaphrojekthi-amakhulu, amaphrojekthi azwelayo-njengemisebenzi yesikhashana, ukusatshalaliswa kwamanzi ezindaweni zasemakhaya noma amafreyimu alula, -umucu othathiwe (ipayipi lekhoyili eliwuthayela) ebangeni lika-60–150 g/m² kungaba ukukhetha ukonga. Lawa mapayipi anathayela afaneleka uma impilo yokuklama nokuchayeka kuphakathi nendawo futhi ukushintshwa noma ukuphinda kwamukelekile.
Ngokufanisaukuqina kwe-zinc enamathelafuthiinqubo galvanizingesigabeni sangempela sokugqwala sephrojekthi yakho, ungakwazi ukunweba impilo yesevisi, ugweme ukwehluleka ngaphambi kwesikhathi futhi ugcine izindleko zokuyilungisa zilawulwa.
Ungayikhetha kanjani indinganiso yamapayipi othayela efanele yephrojekthi yakho?
Izinga olikhethayo liyanqumaubukhulu bodonga, izakhiwo zemishini kanye nesisindo esincane se-zinc coating, futhi iyisici esibalulekile ekuzinzeni okuphelele kwephrojekthi kanye nezindleko zomjikelezo wempilo.
Ngobaizindawo zokugqwala okuphansi kuya kokuphakathinjengezakhiwo zezentengiselwano,{0}}ukusabalalisa amanzi anengcindezi ephansi negesi, amanethiwekhi okufafaza umlilo kanye namasistimu e-HVAC,Ipayipi lensimbi le-ASTM A53isetshenziswa kabanzi. I-coating evamile eshisayo-yaleli zinga iseduze1.8 oz/ft² (≈0.55 kg/m²), okwanele ukuchayeka ngaphandle kwangaphakathi noma okuthambile.
Ngokudluliswa kwamanzi, izintambo zokudonsa amanzi aluhlaza, amapayipi amanzi agqitshiwe kanye nezinhlelo zamanzi angcolile ahlala echayeka emanzini nasenhlabathini, i-AWWA C200 kanye namazinga ahlobene okusebenza kwamanzi avame ukucaciswa. Lapha, kunconywa izimbobo ze-zinc ezingu-2.0 oz/ft² (≈0.61 kg/m²) noma ngaphezulu, zinikeze isivikelo esingcono kumapayipi amanzi kamasipala, izintambo zokukhucululwa kwendle namanzi angcolile, izindawo zokuhlanza kanye neziteshi zokumpompa.
Ngokuya ngephrojekthi yakho, singasebenza futhiI-EN noma i-ISO galvanized pipe standardslapho kusebenza khona izinkambiso ezithile zesifunda noma izidingo zeklayenti. Indima yethu ukukusiza ukuthi ukhethe izinga elibhalansisa:
- impilo yokuklama edingekayo
- imvelo (ngaphakathi/ngaphandle, inhlabathi, olwandle, izimboni)
- ukucindezela nokulayisha ngomshini
- izimo zokufakwa nokugcinwa
ukuze uhlelo lwakho lwamapayipi ensimbi luhlale luzinzile kuyo yonke impilo yephrojekthi.
Ungaqinisekisa kanjani ukuthi ikhwalithi yamapayipi anothayela ihlangabezana nezidingo zephrojekthi?

Ngamagama asebenzayo, "i-zinc ehambisana ne-ASTM B6" isho ukusebenzisa-izinki ezihlanzekile eziphakeme ezinamaleveli alawulwa ngokuqinile omthofu, i-cadmium, insimbi nezinye izici zokulandela umkhondo. I-ASTM B6 ichaza amamaki e-zinc amaningana anokuqukethwe kwe-zinc okuncane kanye nemikhawulo yokungcola ephezulu ukuze kuqinisekiswe uketshezi oluhle endaweni eshisayo-ekubhavu wediphu, ukujiya kokuqina okuqinile nokunamathela okuqinile endaweni yensimbi. Ngokusebenzisa kuphela i-ASTM B6-i-zinc ethobelanayo, i-zinc eshisayo-ye-dip galvanized ihlinzeka ngokumelana nokugqwala okubikezelwe futhi igwema ukonakala okungase kuvele uma kusetshenziswa i-zinc yezinga eliphansi noma egaywe kabusha.

Izicelo ezijwayelekile - ukuthi ipayipi elinothayela livikela kanjani imikhakha ehlukene
Ngenxa yokwembozwa kwe-zinc nomzimba wensimbi oqinile,ipayipi lensimbiisetshenziswa kabanzi lapho kudingeka khona ukulingana kwamandla, izindleko kanye nokumelana nokugqwala.
Izimo ezijwayelekile zohlelo lokusebenza zifaka:
- Ukwakha nokwakha
Amapayipi amanzi emvula angaphandle, ama-handrails, ojantshi abaqaphayo, izisekelo zamakhebula kanye namalungu alula wesakhiwo achayeke esimweni sezulu. Ipayipi elinothayela linciphisa ukupendiwa kabusha kanye nokulungisa imvamisa ezimvilophini zokwakha namangaphambili.
- Izinhlelo zamanzi namanzi angcolile
Ukusabalalisa amanzi aphuzwayo, amapayipi omlilo, izintambo zokuchelela kanye nezingxenye zeamanethiwekhi amanzi angcolile kanye nendlelapho kudingeka khona ukuvikelwa kokugqwala okusesilinganisweni. Ipayipi elinothayela livame ukusetshenziswa-ezigabeni ezingaphezulu, emagumbini okumpompa kanye nasezindaweni zokuhlanza.
- Amapayipi okusetshenziswa kwezimboni
Umoya ocindezelwe, amanzi okupholisa,{0}}amanzi anengcindezi ephansi kanye nemigqa yesevisi ejwayelekile ezimbonini nasezitshalweni. Ipayipi lensimbi eliphehliwe linikeza ukuvikeleka okuhlala isikhathi esideisimo sezimboni, ama-workshops nama-rack pipe racks.
- Ukugcina nokudlulisa uwoyela ({0}}ingcindezi ephansi)
Imigqa{{0}yamafutha anomfutho ophansi, udizili kanye nemigqa yokudlulisa uwoyela we-lube ezungeze amathangi, izindawo zokulayisha namatheminali. Amapayipi anamathangi ahlinzeka ngamandla,{2}}okulula{3}}ukugcina isixazululo sokuphindaphindeka kwangaphandle, izingalo ezilayishayo, ama-pump skid namasistimu kawoyela asetshenziswayo achayeke kumswakama kanye nokuchaphazeka kwezikhathi ezithile.
- Amanethiwekhi okusabalalisa igesi kanye nezinsiza
Igesi yemvelo enengcindezi{{0}ephansi kanye nokusatshalaliswa kwe-LPG ngaphakathi kwezakhiwo noma ngaphakathi kwezinhlelo zensiza yezitshalo, lapho amakhodi evumela amapayipi anamathani. I-zinc enamathela iyavikelangenhla-izintambo zikaphethiloli, ukugijima kwamamitha kanye namapayipi angaphakathi avela ku-condensation kanye nesimo sezulu esithambile sezimboni.
- Uthango nemisebenzi yesakhiwo esilula
Biyela izigxobo, izigxobo zezimpawu, izikafula kanye nezakhiwo zesikhashana, ikakhulukazi kuamaphrojekthi asemaphandleni, ezolimo kanye nengqalasizinda, lapho kudingeka khona isisombululo esiqinile kodwa esinomnotho.
Ngokukhetha ukucaciswa kwepayipi eliyisithako esilungile kanye neleveli yokumboza ngayinye yalezi zimo, uthuthukisa ukwethembeka kwesistimu futhi wehlise izindleko eziphelele zokulungisa.
Kungani usikhethe njengomphakeli wakho wamapayipi ensimbi
Njengomuntu okhethekileumphakeli wamapayipi ensimbi, senza okungaphezu kokuthengisa izinto ezijwayelekile zekhathalogi. Sikusiza ukuthi wakhe isixazululo mayelana nephrojekthi yakho:
- Ukumbozwa kwe-zinc ngokwezifiso nokukhethwa kwenqubo
Idiphu eshisayo eshisayo-esetshenziswa ogwini nasolwandle, idiphu evamile eshisayo-yezakhiwo nezinhlelo zezimboni, noma ngaphambili{2}}ipayipi lekhoyili elakhiwe{3}}lomthamo omkhulu, obizayo{4}}lomsebenzi ozwelayo-okhethwe ngokwendawo yakho nempilo yokuklama.
- Amazinga kanye nokucaciswa okuhambisana nomkhakha wakho
Sinikezela ngepayipi likathayelaI-ASTM A53, AWWA C200 kanye namazinga ahlobene, ngesisindo sokumboza, ibanga lokusebenza kanye nobubanzi bokuhlola obulungiselelweimisebenzi yamanzi, izinsiza zokwakha, izinsiza zikawoyela negesi noma izimboni zezimboni.
- Qeda ukuqeda nokucubungula kuphakheji eyodwa
Ipayipi elinemicu, eligobile noma elivalekile elinama-couplings afanayo, ama-flange nokufakwa kungahlinzekwa ndawonye, kuncishiswe ukusebenzisana phakathi kwabathengisi abaningi nokwenza ukufakwa kwesayithi kusheshe.
- Ikhwalithi ebhaliwe nokusekelwa kobuchwepheshe
Uthola amadokhumenti okuhlola aphelele namarekhodi okuhlanganisa, kanye nokusekelwa konjiniyela ekukhetheni ukunamathela, ukukhetha okujwayelekile kanye nezimo zohlelo lokusebenza, ukuze ithimba lakho likwazi ukuthethelela izinqumo kubanikazi nabaxhumanisi.
Ngeyethuinkambiso ipayipi izixazululo, ungacacisa kahle lokho okudingayo kuphrojekthi ngayinye-ukujiya koqweqwe, okujwayelekile, ukuqedwa nokupakishwa{1}}futhi uthole iphakheji elungele ukufakwa, eqinile ekusebenzeni futhi kulula ukuyinakekela ngokuhamba kwesikhathi.
