Intsimbi ye-ASTM A513ngumbhobho wentsimbi yekhabhoni kunye ne-alloy kunye netyhubhu eyenziwe ngentsimbi eqengqelekayo okanye eqengqelekayo njengezinto eziluhlaza ngenkqubo yokumelana nokushisa (ERW), esetyenziswa kakhulu kuzo zonke iintlobo zezakhiwo zoomatshini.
Uhlobo 1 lunokwahlulwa lube yi-1a kunye ne-1b.
Uhlobo 1a (AWHR): "njenge-welded" eyenziwe ngentsimbi eqengqelekayo eshushu (enesikali yokugaya).
Olu hlobo lombhobho ludityaniswa ngqo kwintsimbi eqengqelekayo eshushu kunye ne-iron oxide (isikali sombhobho) eyenziwe ngexesha lokuqengqeleka. Olu hlobo lombhobho luhlala lusetyenziswa kwiindawo apho ukuthembeka komphezulu kungabalulekanga kuba umphezulu unesikali sombhobho.
Uhlobo 1b (AWPO): "njenge-welded" eyenziwe ngentsimbi eqhotsiweyo nefakwe ioyile eshushu (isusiwe isikali somatshini wokugaya).
Olu hlobo lombhobho ludityaniswe ngentsimbi egoqwe ngobushushu efakwe i-pickle yaza yafakwa i-oyile kwaye iphawulwa ngokususwa kwesikali se-mill. Unyango lwe-pickling kunye ne-oyile alususi nje kuphela i-oxidation yomphezulu kodwa lukwabonelela ngokhuseleko lokugqwala kunye nokuthambisa ngexesha lokucubungula, okwenza lo mbhobho ufaneleke ngakumbi kwizicelo ezifuna umphezulu ococekileyo okanye iimeko zokucubungula eziqinileyo kancinci.

Ishushu-iqengqeleka
Kwinkqubo yokuvelisa, intsimbi eqengqelekayo eshushu iqala ifudunyezwe kubushushu obuphezulu, nto leyo evumela intsimbi ukuba iqengqeleke ikwimeko yeplastiki, nto leyo eyenza kube lula ukutshintsha imo kunye nobukhulu bentsimbi. Ekupheleni kwenkqubo yokuqengqeleka eshushu, izinto zihlala zikhula kwaye zijijeke.
Iityhubhu mazizenziwe yiedityaniswe ngombane (ERW)inkqubo.
Umbhobho we-ERW yinkqubo yokwenza i-weld ngokufaka izinto zesinyithi kwisilinda kunye nokusebenzisa ukumelana kunye noxinzelelo kubude bayo.
Intsimbi mayihambelane neemfuno zokwakheka kweekhemikhali ezichazwe kwiTheyibhile 1 okanye kwiTheyibhile 2.

I-RB ibhekisa kwiRockwell Hardness B Scale.
Iimfuneko zobunzima ezihambelana namanqanaba athile zinokujongwa kwiitheyibhile engasentla ye-RB.
I-1% yazo zonke iityhubhu kwindawo nganye kwaye kungabi ngaphantsi kweetyhubhu ezi-5.
Iityhubhu ezingqukuva kunye neetyhubhu ezenza ezinye iimilo xa zingqukuva ziyasebenza.
Zonke iityhubhu ziya kunikwa uvavanyo lwe-hydrostatic.
Gcina uxinzelelo oluphantsi lovavanyo lwe-hydro ubuncinane ubuncinane imizuzwana emi-5.
Uxinzelelo lubalwa ngolu hlobo:
P=2St/D
P= uxinzelelo oluncinci lovavanyo lwe-hydrostatic, i-psi okanye i-MPa,
S= uxinzelelo lwefayibha oluvumelekileyo lwe-14,000 psi okanye i-96.5 MPa,
t= ubukhulu bodonga obuchaziweyo, ngaphakathi okanye mm,
D= ububanzi obungaphandle obuchaziweyo, ngaphakathi okanye mm.
Injongo yolu vavanyo kukwala iityhubhu ezineziphene ezinobungozi.
Ityhubhu nganye mayivavanywe ngovavanyo lombane olungatshabalalisiyo ngokwe-Practice E213, Practice E273, Practice E309, okanye Practice E570.

Phawula ulwazi olulandelayo ngendlela efanelekileyo kwintonga nganye okanye iphakheji.
igama lomenzi okanye uphawu, ubungakanani obuchaziweyo, uhlobo, inombolo yeodolo yomthengi, kunye nale nombolo yeenkcukacha.
I-Barcoding iyamkeleka njengendlela eyongezelelweyo yokuchonga.
Umbhobho awufanele ube neziphene ezinobungozi kwaye kufuneka ube nomgangatho ofana nowenziwe ngumntu.
Iziphelo zombhobho mazinqunyulwe kakuhle kwaye zingabi naziphelo okanye imiphetho ebukhali.
Itshiphu Eqengqelekayo (yohlobo lwe-1a): Uhlobo lwe-1a (oluvela ngqo kwintsimbi eqengqelekayo eshushu enezitshiphu eziqengqelekayo) ludla ngokuba nomphezulu wetshiphu oqengqelekayo. Le meko yomphezulu iyamkeleka kwiindlela ezithile apho umgangatho ophezulu womphezulu ungadingeki.
Itshiphusi eqengqiweyo esusiweyo (yohlobo lwe-1b): Uhlobo lwe-1b (lwenziwe ngentsimbi eshushu egoqwe nge-pickled ne-oyile kunye neetshiphusi ezigoqwe zisusiwe) lubonelela ngomphezulu ococekileyo kwizicelo ezifuna ukupeyintwa okanye umgangatho ongcono womphezulu.
Imibhobho mayigqunywe ngefilimu yeoyile ngaphambi kokuba ithunyelwe ukuze kuthintelwe umhlwa.
Ukuba iodolo ichaza ukuba iityhubhu mazithunyelwe ngaphandleioyile ethintela umhlwa, ifilimu yeoyile enokwenziwa iya kuhlala phezu komhlaba.
Ingathintela ngempumelelo umphezulu wombhobho ukuba ungahlangani nokufuma kunye neoksijini emoyeni, ngaloo ndlela iphephe ukugqwala kunye nokubola.
Ixabiso eliphantsi: Inkqubo yokuwelda intsimbi egoqwe ngobushushu yenza i-ASTM A513 Type 1 ifikeleleke ngakumbi xa ithelekiswa neemveliso ezitsalwa ngokubandayo.
Uluhlu olubanzi lwezicelo: Uhlobo lwe-ASTM A513 1 lufanelekile kwiintlobo ngeentlobo zezicelo, kubandakanya izinto zokwakha, iifreyimu, iishelufu, nokunye. Ukuguquguquka kwayo kwiindawo ezahlukeneyo kunye nemisebenzi kuyenza ibe lukhetho oludumileyo kumashishini afana neemoto, ezokwakha, kunye noomatshini.
Ukudityaniswa kakuhle: Ukwakheka kweekhemikhali ze-ASTM A513 Type 1 kulungile ekudibaniseni, kwaye ingadityaniswa kusetyenziswa iindlela ezininzi zesiqhelo zokudityaniswa, nto leyo eyenza ukuba isebenze ngakumbi kwiindawo ezahlukeneyo zokwenza.
Amandla nokuqina okuhleNangona ingekho qinile njengezinye iintsimbi ze-alloy okanye iintsimbi ezilungisiweyo, iyahlangabezana neemfuno zokubonelela ngamandla aneleyo kwiindlela ezininzi zokwakha nezoomatshini. Ukucubungula okungakumbi, okufana nonyango lobushushu, kunokuphucula iipropati zoomatshini zombhobho ukuze kuhlangatyezwane neemfuno ezithile.
Umphezulu wokugqibaUhlobo lwe-1b lubonelela ngomphezulu ococekileyo, oluncedo xa kufuneka ugqitywe kakuhle umphezulu kwaye apho kufuneka upeyintwe okanye kulungiswe umphezulu ngakumbi.
Uhlobo lwe-ASTM A513 1 lubonelela ngokulinganisela okuhle kweendleko, ukusebenza, kunye nokuguquguquka, okwenza ukuba ifaneleke kwiindlela ezininzi zoomatshini kunye nolwakhiwo apho kufuneka khona iityhubhu ezingabizi kakhulu ezineempawu ezilungileyo zoomatshini.
Isetyenziswa ekwakheni njengezakhiwo ezixhasayo ezifana neebhari kunye neekholamu.
Isetyenziswa ekuveliseni iindawo zesakhiwo zezixhobo ezahlukeneyo zoomatshini, ezifana neebheringi kunye neeshafti.
Isakhelo kunye nezakhiwo zenkxaso kwimishini yezolimo.
Isetyenziselwa ukwakha iishelufu zesinyithi kunye neenkqubo zokugcina izinto kwiindawo zokugcina impahla nakwiivenkile.
Singomnye wabavelisi kunye nababoneleli abaphambili bemibhobho yentsimbi yekhabhoni edityanisiweyo kunye nemibhobho yentsimbi engenamthungo abavela eTshayina, sinoluhlu olubanzi lwemibhobho yentsimbi ekumgangatho ophezulu ekhoyo, sizimisele ukukunika uluhlu olupheleleyo lwezisombululo zemibhobho yentsimbi.
Ukuze ufumane iinkcukacha ezithe vetshe ngemveliso, nceda unxibelelane nathi, silangazelela ukukunceda ufumane ezona ndlela zibalaseleyo zombhobho wentsimbi kwiimfuno zakho!
