Ukususela ekuyilweni kwayo kwinkulungwane edlulileyo, intsimbi engenastainless iye yaba yeyona nto isetyenziswayo nethandwayo ehlabathini. Umxholo weChromium unika ukuxhathisa kwawo ngokuchasene nokubola. Ukuchasana kunokubonakaliswa ekunciphiseni i-acids kunye nokuhlaselwa kwe-pitting kwizisombululo ze-chloride. Inesidingo esincinci sokulondolozwa kunye nokukhanya okuqhelekileyo, okwenza kube yinto egqwesileyo kunye neyona nto igqwesileyo kwimibhobho yensimbi engenasici. Umbhobho wensimbi engenasici unikezelwa kwiintlobo ezahlukeneyo zeemveliso, kubandakanywa imibhobho edibeneyo kunye nemibhobho engenamthungo. Ukubunjwa kunokutshintsha, ukuvumela ukuba kusetyenziswe kumacandelo ahlukeneyo. Umbhobho wensimbi engenasici usetyenziswa rhoqo ngamashishini amaninzi. Kule post blog, iintlobo ezahlukeneyo zemibhobho yensimbi engenasici ngokweendlela zokuvelisa kunye nemigangatho eyahlukeneyo iya kukhankanywa. Ukongeza koko, le post blog ikwaneendawo ezahlukeneyo zesicelo semibhobho yensimbi engenasici kumashishini ahlukeneyo.

Iindidi ezahlukeneyo zeImibhobho yeStainless SteelNgokusekelwe kwindlela yoMveliso

Ubuchwephesha bokuvelisa imibhobho edibeneyo ukusuka kwikhoyili eqhubekayo okanye ipleyiti ibandakanya ukuqengqeleka kweplate okanye ikhoyili kwicandelo lesetyhula ngoncedo lwe-roller okanye izixhobo zokugoba. Izinto zokuzalisa zingasetyenziselwa kwimveliso enkulu. Imibhobho edityanisiweyo inexabiso eliphantsi kunemibhobho engenamthungo, enendlela yokuvelisa ngokubanzi exabisa kakhulu. Nangona ezi ndlela zokuvelisa, ezizezi, iindlela zokuwelda ziyinxalenye ebalulekileyo yemibhobho yentsimbi engatyiwa, iinkcukacha zezi ndlela zokuwelda aziyi kukhankanywa. Inokuba sisihloko sesinye isithuba sebhlog yethu. Xa sele nditshilo, iindlela zokuwelda kwimibhobho yentsimbi engenasici zidla ngokuvela njengezifinyezo. Kubalulekile ukuzazi ezi zishunqulelo. Kukho iindlela ezininzi ze-welded, ezifana:

• EFW– Ukudibanisa ukuwelda kombane
• ERW– Ukumelana ne-welding yombane
• HFW– High frequency welding
• WABONA-Ukuwelda kwe-arc emanzini (umthungo ojikelezayo okanye umthungo omde)

Kukho neentlobo ezingenamthungo zemibhobho yensimbi engenasici kwiimarike. Kwiinkcukacha ezithe kratya, emva kokuveliswa kwe-welding yokumelana nombane, isinyithi siqengqeleka kuyo yonke ubude bayo. Umbhobho ongenamthungo wabo nabuphi na ubude unokwenziwa ngokukhutshwa kwentsimbi. Imibhobho ye-ERW inamajoyinti adityaniswe ecaleni kwawo anqamlezileyo, ngelixa imibhobho engenamthungo inamalungu ahamba ubude bombhobho. Akukho ukuwelda kwimibhobho engenamthungo ekubeni yonke inkqubo yemveliso yenziwa ngebillet eyomeleleyo. Ngobubanzi obuhlukeneyo, imibhobho engenamthungo yagqityezelwa kubukhulu bodonga kunye neenkcukacha ezinobungakanani. Ekubeni kungekho mthungo kumzimba wombhobho, le mibhobho isetyenziswa kwizicelo zoxinzelelo oluphezulu ezifana nokuthuthwa kweoli kunye negesi, amashishini, kunye nokucoca.

Iindidi zemibhobho yentsimbi estainless - Ngokusekwe kumaBanga eAlloy

Ukubunjwa kweekhemikhali zensimbi jikelele kunempembelelo enkulu kwiipropathi zokugqibela zemveliso kunye neendawo zokusetyenziswa. Ngoko, akumangalisi ukuba banokuhlelwa ngokweendlela zabo zeekhemikhali. Nangona kunjalo, ngelixa uzama ukufumanisa ibakala lombhobho othile wensimbi engenasici, iintlobo ezahlukeneyo ze-nomenclatures zinokudibana nazo. Imigangatho esetyenziswa kakhulu xa kutyunjwa imibhobho yensimbi yi-DIN (isiJamani), i-EN, kunye namabakala e-ASTM. Umntu unokujongana netheyibhile yeereferensi ukuze afumane amabakala alinganayo. Itheyibhile engezantsi inika isishwankathelo esiluncedo sale migangatho yahlukeneyo.

Iintlobo ezahlukeneyo Ngokusekwe kwiiNgcaciso ze-ASTM

Lilizwi eliqhelekileyo elithi ishishini kunye nemigangatho zibotshelelwe ngokusondeleyo. Iziphumo zokwenziwa kunye novavanyo zinokwahluka ngenxa yomahluko kwimigangatho eyahlukeneyo yombutho kwiindidi ezahlukeneyo zezicelo. Umthengi kufuneka aqale aqonde iziseko zeenkcukacha ezahlukeneyo zemizi-mveliso yeeprojekthi zabo, ngaphambi kokuba enze imisebenzi yokuthenga. Ikwayintetho echanekileyo kwimibhobho yensimbi engenasici.

I-ASTM sisishunqulelo se-American Society for Testing and Materials. I-ASTM International ibonelela ngemigangatho yenkonzo kunye nemathiriyeli yoshishino kuluhlu olubanzi lwamashishini. Lo mbutho ngoku ukhonze imigangatho eyi-12000+ esetyenziswa kumashishini kwihlabathi liphela. Imibhobho yensimbi engenasici kunye nezixhobo zixhomekeke kwimigangatho ye-100. Ngokungafaniyo neminye imizimba esemgangathweni, i-ASTM ibandakanya phantse zonke iintlobo zemibhobho. Ngokomzekelo, njengezinto zombhobho waseMelika, i-spectrum yonke yombhobho inikezelwa. Imibhobho yekhabhoni engenamthungo eneenkcukacha ezifanelekileyo isetyenziselwa iinkonzo zobushushu obuphezulu. Imigangatho ye-ASTM ichazwa ngokumiselwa kokwakheka kweekhemikhali kunye neenkqubo ezithile zemveliso ezinxulumene nemathiriyeli. Eminye imigangatho yezinto ze-ASTM inikwe ngezantsi njengemizekelo.

• A106– Ngeenkonzo zobushushu obuphezulu
• A335-Imibhobho yentsimbi engenamthungo (Ngobushushu obuphezulu)
• A333-Imibhobho yentsimbi edityanisiweyo kunye nengenamthungo (Ngobushushu obuphantsi)
• A312-Kwinkonzo ye-corrosion jikelele kunye nenkonzo yobushushu obuphezulu, i-welded esebenzayo ebandayo, i-weld seam edibeneyo, kunye nemibhobho engenamthungo iyasetyenziswa.

Iintlobo ezahlukeneyo zeMibhobho yentsimbi eNgatyiwayo esekwe kwiiNdawo zeSicelo

Imibhobho yococeko:Imibhobho yococeko yenziwe ngentsimbi engenasici kwaye isetyenziswa kwizicelo eziphezulu zococeko ezifana nezicelo ezinovakalelo. Olu hlobo lombhobho lunikwa eyona nto iphambili kushishino lokuhamba kwamanzi okusebenzayo. Umbhobho unokumelana nokugqwesa okugqwesileyo kwaye awuvuthi ngenxa yokulula kwayo ukugcinwa. Imida eyahlukeneyo yokunyamezela imiselwa ngokusekelwe kwisicelo. Imibhobho yococeko enemigangatho ye-ASTMA270 isetyenziswa ngokuqhelekileyo.

Imibhobho yoomatshini:Amacandelo angcwele, iinxalenye zokuthwala, kunye neenxalenye ze-cylinder ziqhelekileyo zisetyenziswa kwizicelo zemibhobho yomatshini. Ubuxhakaxhaka bunokulawulwa ngokulula kuluhlu olubanzi lweesheyiphu zecandelo ezifana noxande, isikwere, kunye nezinye iimilo ezidibanisa ukuya kwiimilo eziqhelekileyo okanye eziqhelekileyo. I-A554 kunye ne-ASTMA 511 zezona ntlobo zebakala zidla ngokusetyenziswa kwizicelo zoomatshini. Zinobugcisa obugqwesileyo kwaye zisetyenziswa kwizicelo ezifana neemoto okanye oomatshini bezolimo.

Imibhobho ekhazimlisiweyo:Imibhobho yentsimbi epholisiweyo isetyenziswa kwiziko lasekhaya ngokuxhomekeke kwiinkcukacha. Imibhobho epholisiweyo inceda ekunciphiseni ukuguga kunye nokukrazula kwizinto zokusebenza. Ikwanceda ekunciphiseni ukubambelela kunye nokungcoliswa kwezixhobo ezahlukeneyo. Umphezulu we-electropolished unoluhlu olubanzi lokusetyenziswa. Imibhobho epholisiweyo yensimbi engenasici ayifuni nakuphi na ukoleka okungaphezulu. Imibhobho ekhazimlisiweyo inendima ebalulekileyo kwaye ibaluleke kakhulu kubuhle kunye nokusetyenziswa kwezakhiwo.
