Umgangatho ophezulu wentsimbi yesikwere ityhubhu
Insimbi engenasici ityhubhu yesikwere luhlobo lwentsimbi ende enomngxuma. Ngenxa yokuba icandelo lisisikwere, libizwa ngokuba ityhubhu yesikwere. Inani elikhulu lemibhobho lisetyenziselwa ukuthutha ulwelo, olufana neoyile, igesi yendalo, amanzi, igesi, umphunga, njl njl. Ukongeza, xa ukugoba kunye namandla okugoba kuyafana, ubunzima buyakhanya, ngoko ke nabo babanzi. isetyenziswe ekwenziweni kwamalungu oomatshini kunye nezakhiwo zobunjineli.
Ulwahlulo lombhobho wesikwere sensimbi engenasici: umbhobho wesquare uhlukaniswe kumbhobho wensimbi ongenamthungo kunye nombhobho wensimbi odibeneyo (umbhobho odibeneyo). Ngokutsho kobume becandelo, inokwahlulwa ibe yimibhobho yesikwere kunye noxande. Imibhobho yentsimbi ejikelezayo isetyenziswa kakhulu, kodwa kukwakho nemibhobho yentsimbi enemilo ekhethekileyo efana nesemicircular, hexagonal, equilateral triangle kunye neoctagonal.
Kumbhobho wesquare wensimbi engenastainless ethwele uxinzelelo lolwelo, uvavanyo lwehydraulic luya kwenziwa ukujonga ukumelana noxinzelelo kunye nomgangatho. Ifanelekile ukuba akukho ukuvuza, ukumanzisa okanye ukwandiswa phantsi koxinzelelo oluchaziweyo. Eminye imibhobho yentsimbi iya kuba phantsi kovavanyo lwe-crimping, uvavanyo lwe-flaring, uvavanyo lokucaba, njl. ngokomgangatho okanye iimfuno zomfaki-sicelo.
Ukucaciswa kwetyhubhu yesikwere: 5 * 5 ~ 150 * 150 mm ubukhulu: 0.4 ~ 6.0 mm
Izinto ityhubhu yesikwere: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347h, 310S
Izinyithi zinokusabela ngeoksijini kwi-atmosfera ukuze zenze ifilimu ye-oxide phezu komhlaba. I-iron oxide eyenziwe kwi-carbon steel eqhelekileyo iya kuqhubeka i-oxidize, yandisa i-corrosion kwaye ekugqibeleni yenza imingxuma. Oku kunokusebenzisa ipeyinti okanye i-oxidation resistant metal ye-electroplating ukukhusela umphezulu we-carbon steel, kodwa lo maleko okhuselayo yifilimu encinci kuphela. Ukuba uluhlu olukhuselayo lonakaliswe, intsimbi engaphantsi iya kuqala ukugqwala kwakhona. Ingaba ipayipi yensimbi engenasici i-corrod ihambelana nomxholo we-chromium kwintsimbi. Xa umxholo we-chromium kwintsimbi ufikelela kwi-12%, umaleko we-chromium etyebileyo kunye ne-chromium eshinyeneyo yenziwe kumphezulu wombhobho wensimbi engenasici kwi-atmosfera ukukhusela umphezulu kunye nokuthintela ukuphinda kuphinde kuphinde kubekho i-oxidation. Lo maleko weoksidi ubhityile kakhulu. Ngalo, unokubona ukukhazimla kwendalo kwendawo yentsimbi, eyenza ukuba intsimbi engenasici ibe nendawo ekhethekileyo. Ukuba ifilimu ye-chromium yonakele, i-chromium kwintsimbi kunye ne-oksijini esemoyeni iya kuhlaziya ifilimu ye-passive ukuze iqhubeke idlala indima yokukhusela. Kwezinye iindawo ezikhethekileyo, insimbi engenasici iya kusilela kwakhona ngenxa ye-corrosion ethile yendawo, kodwa ngokungafaniyo ne-carbon steel, insimbi engenasici ayiyi kusilela ngenxa ye-corrosion efanayo, ngoko ke isibonelelo se-corrosion singenantsingiselo kwimibhobho yensimbi engenasici.
