Imibhobho yentsimbi yimibhobho yentsimbi apho iingcingo zombane kunye neentambo zihamba khona

Imibhobho yentsimbi yimibhobho yentsimbi apho iingcingo zombane kunye neentambo zihamba khona.Inika ukhuseleko olubalulekileyo kwiingcingo kunye neentambo kumonakalo kunye naziphi na iimpembelelo.
I-Henfen ibonelela ngetyhubhu esemgangathweni ye-conduit ene-zinc egqunywe ngokufanayo, idiphu eshushu efakwe amagalvan ngaphakathi nangaphandle.Yenziwe kwi-BS 4568 EN-BS31-1940.
Kwakhona, iHenfen ibonelela ngoluhlu olubanzi lwezixhobo zentsimbi yombhobho.
I-Henfen ibonelela ngeentlobo ezimbini zemibhobho yocingo eqhelekileyo: umgangatho waseBritani kunye nomgangatho waseMelika.Imigangatho ephambili yaseBrithani yi-BS4568 kunye ne-BS31-1940.Ubungakanani ubukhulu becala 20mm, 25mm, 32mm.Le mibhobho yentsimbi inokudityaniswa, kodwa ifuna ingqalelo kumsebenzi wobugcisa.Emva kwe-welding, umbhobho we-galvanized kufuneka uphuculwe, ngaphandle koko umgangatho uya kuchaphazeleka, kwaye i-blistering enzulu okanye i-rust iya kwenzeka.Imibhobho yegalvanized isetyenziselwa ukukhusela iingcingo kunye neentambo.Uninzi lwezindlu ezindala zisebenzisa imibhobho eyenziwe ngamazinki.Ngoku umbhobho ofakwe igalvanized usetyenziselwa irhasi kunye nokufudumeza.
Ziziphi iimpawu zombhobho wegalvanized?
1. Ixabiso eliphantsi lokucubungula: Iindleko ezichasene ne-rust ye-hot-dip galvanizing ziphantsi kunezinye iipeyinti kunye neengubo, kwaye ixabiso liphantsi kakhulu.
2. Ihlala ixesha elide: Umphezulu we-hot-dip galvanized steel pipe uqaqambile ngokukodwa, umaleko we-zinc ufana, akukho kuvuza, akukho kuthontsiza, ukuncamathela okuqinileyo kunye nokuxhathisa okuqinileyo kwe-corrosion.Imekobume yedolophu inyuke kabukhali, kwaye ubungqingqwa bomgangatho oshushu-diphu ochasene nomhlwa bunokugcinwa ngaphezulu kweminyaka engama-50 ngaphandle kokugcinwa.Kwimimandla yasezidolophini okanye kude nonxweme, umaleko oqhelekileyo wokuchasa umhlwa oshushu-dip ungagcinwa malunga neminyaka engama-20 ngaphandle kokulungiswa.
3. Ukuthembeka okulungileyo: Uluhlu oluphezulu lombhobho we-galvanized luhlanganiswe nge-metallurgically kunye nentsimbi, kwaye umbhobho wensimbi owenziweyo wenziwa phezu kwentsimbi, ngoko ke ukuqina kwengubo kunokwethenjelwa.
4. Isigqubuthelo sinokuqina okuqinileyo: i-zinc coating yenza isakhiwo esikhethekileyo se-metallographic, esinokuxhathisa ngokubanzi umonakalo womatshini ngexesha lokuthutha kunye nokusetyenziswa.
5. Ukhuseleko olubanzi: Yonke inxalenye yenxalenye yesilivere inokuphinda ifakwe i-galvanized, kunye neendawo zokuhlala, iikona ezibukhali kunye neendawo ezifihlakeleyo zinokukhuselwa ngokupheleleyo.
6. Gcina ixesha kunye nabasebenzi: Inkqubo ye-galvanizing ikhawuleza kunezinye iindlela zokwakha zokugquma, ezinokuthi zigweme ixesha elifunekayo lokupenda kwindawo yokwakha emva kokufakwa.
