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 5ngaphakathi komgangatho we-ASTM A513 ubhekisa kwiIdwetshwe phezu kweMandrel (DOM)ityhubhu.
Iityhubhu zeDOM ziveliswa ngokwenza ityhubhu edibeneyo kuqala uze uyitsale ngokubandayo kwiidayi kwaye uyisebenzise phezu kweemandrel ukuze igqitywe ifikelele kumlinganiselo osondeleyo kunye nokugqitywa komphezulu okuthambileyo xa kuthelekiswa nezinye iintlobo zeetyhubhu ezidibeneyo.

Iintlobo ze-ASTM A513 zahlulwe ngokweemeko okanye iinkqubo ezahlukeneyo zombhobho wentsimbi.
Uhlobo lwe-ASTM A513 oluyi-round tube type 5 luqhelekileyo ngala:
1008, 1009, 1010, 1015, 1020, 1021, 1025, 1026, 1030, 1035, 1040, 1340, 1524, 4130, 4140.
Ijikelezileyo
Isikwere okanye uxande
Ezinye iimilo
ezifana nemilo ecwangcisiweyo, enesiqingatha, enesiqingatha, engqukuva ngaphakathi kunye nenesiqingatha okanye enesiqingatha ngaphandle, enemiqolo ngaphakathi okanye ngaphandle, enemilo emithathu, enesiqingatha esingqukuva, kunye nemilo ye-D.
Intsimbi eqengqelekayo eshushu okanye ebandayo
Izinto ezisetyenziswa ekuveliseni i-Hot-rolled okanye i-Cold-rolled Steel zinokwenziwa nangayiphi na indlela.
Intsimbi Eqengqelekayo Eshushu: 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.
Intsimbi Eqengqelekayo Ebandayo: Intsimbi eqengqelekayo ebandayo iqengqeleka ngakumbi emva kokuba izinto zipholile ukuze kufezekiswe ubungakanani kunye nemilo oyifunayo. Le nkqubo idla ngokwenziwa kubushushu begumbi kwaye iphumela kwintsimbi enomgangatho ophezulu womphezulu kunye nobukhulu obuchanekileyo.
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.

Qaphela 1: La maxabiso asekelwe kumaqondo obushushu aqhelekileyo okunciphisa uxinzelelo lwe-mill. Kwizicelo ezithile, iipropati zingalungiswa ngokuthetha-thethana phakathi komthengi kunye nomvelisi.
Inqaku 2: Kwiimvavanyo ze-longitudinal strip, ububanzi becandelo le-gauge buya kuhambelana ne-A370 Annex A2, Steel Tubular Products, kunye nokutsalwa kwe-0.5 pesenti yamanqaku ukusuka kwi-basic minimum elongation nganye1/32ekunciphiseni [0.8 mm] ubukhulu bodonga ngaphantsi5/16ubukhulu bodonga [7.9 mm] buya kuvunyelwa.
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.
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.
Enyanisweni, nangona i-lubricant esisiseko okanye ifilimu yeoyile elula inokubonelela ngokhuseleko lwexeshana oluthile, kwizicelo ezifuna ukhuseleko oluphezulu, unyango olufanelekileyo lokukhusela ukugqwala kufuneka lukhethwe ngokwemeko nganye.
Umzekelo, kwimibhobho egqunywe ngasese,3PE(i-polyethylene enamaleko amathathu) ingasetyenziselwa ukubonelela ngokhuseleko lokugqwala ixesha elide; kwimibhobho yamanzi,I-FBE(i-fusion-bonded epoxy powder) ingafakwa, ngelixai-galvanizedunyango lunokuba lukhetho olusebenzayo kwiindawo apho kufuneka ukhuseleko kwi-zinc corrosion.
Ngezi teknoloji zikhethekileyo zokukhusela ukugqwala, ubomi benkonzo yombhobho bunokwandiswa kakhulu kwaye ukusebenza kwawo kugcinwe.
