ASTM A513 intsimbii-carbon kunye ne-alloy steel pipe kunye ne-tube eyenziwe kwi-hot-rolled or cold-rolled steel njengento ekrwada ngenkqubo yokumelana ne-welding (ERW), esetyenziswa ngokubanzi kuzo zonke iintlobo zezakhiwo zoomatshini.
Uhlobo loku-1 lunokwahlulwa lube ngu-1a no-1b.
Uhlobo 1a (AWHR): "njenge-welded" ukusuka kwintsimbi eshushu-eshushu (kunye nesikali sokugaya).
Olu hlobo lombhobho ludityaniswe ngokuthe ngqo kwintsimbi eshushu-eshushu nge-iron oxide (i-mill scale) eyenziwe ngexesha lokuqengqeleka.Olu hlobo lombhobho lusoloko lusetyenziswa kwizicelo apho ingqibelelo yomhlaba ayibalulekanga kuba umphezulu uqulethe isikali sokusila.
Uhlobo 1b (AWPO): "njenge-welded" ukusuka kwintsimbi edibeneyo eshushu kunye ne-oiled (i-mill scale isusiwe).
Olu hlobo lombhobho ludityaniswe kwintsimbi eshushu edibeneyo ekhethiweyo kwaye ifakwe ioli kwaye ibonakaliswe ngokukhutshwa kwesikali sokugaya.I-Pickling kunye ne-oiling treatment ayisusi nje kuphela i-oxidation yomhlaba kodwa ibonelela ngokhuseleko lwe-corrosion kunye ne-lubrication ngexesha lokucubungula, okwenza le mbhobho ifaneleke ngakumbi kwizicelo ezifuna indawo ecocekileyo okanye iimeko zokucubungula kancinci.

ASTM A513 Round Tubing Uhlobo loku-1 Amanqaku aqhelekileyo ngala:
1008,1009,1010,1015,1020,1021,1025,1026,1030,1035,1040,1340,1524,4130,4140.
Ishushu-isolwe
Kwinkqubo yokuvelisa, insimbi eshushu ishushu iqala ukushisa kwiqondo lokushisa eliphezulu, ivumela ukuba insimbi ifakwe kwisimo seplastiki, okwenza kube lula ukutshintsha imilo kunye nobukhulu bentsimbi.Ekupheleni kwenkqubo eshushu yokuqengqeleka, izinto eziphathekayo zidla ngokulinganiswa kwaye zikhubazeke.
Iityhubhu ziya kwenziwa yiUkumelana nombane (ERW)inkqubo.
Umbhobho we-ERW yinkqubo yokwenza i-weld ngokudibanisa izinto zetsimbi kwi-cylinder kunye nokusebenzisa ukuxhathisa kunye noxinzelelo kunye nobude bayo.
Intsimbi iya kuhambelana neemfuno zokwakheka kweekhemikhali ezichazwe kwiThebhile 1 okanye kwiTheyibhile 2.

I-RB ibhekisa kwi-Rockwell Hardness B Scale.
Iimfuno zobunzima ezihambelana namabakala athile zinokujongwa kwiitheyibhile engentla ye-RB.
I-1% yazo zonke iibhubhu kwiqashiso ngalinye kwaye ingabi ngaphantsi kweetyhubhu ezi-5.
Iityhubhu ezingqukuva kunye neetyhubhu ezenza ezinye iimilo xa zingqukuva ziyasebenza.
Zonke iityhubhu ziya kunikwa uvavanyo lwe-hydrostatic.
Gcina ubuncinci boxinzelelo lwe-hydro test ungekho ngaphantsi kwe-5s.
Uxinzelelo lubalwa ngolu hlobo:
P=2St/D
P= ubuncinci boxinzelelo lovavanyo lwe-hydrostatic, i-psi okanye iMPa,
S= uxinzelelo lwefiber oluvumelekileyo lwe-14,000 psi okanye i-96.5 MPa,
t= ubukhulu bodonga obuchaziweyo, ngaphakathi okanye mm,
D= icaciswe ngaphandle kwedayamitha, ngaphakathi okanye mm.
Yinjongo yolu vavanyo ukugatya iityhubhu ezineziphene eziyingozi.
ityhubhu nganye iya kuvavanywa ngovavanyo lombane olungonakalisiyo ngokuhambelana ne-Practice E213, Practice E273, Practice E309, or Practice E570.

igama lomenzi okanye ibhrendi, ubungakanani obuchaziweyo, uhlobo, inombolo yeodolo yomthengi, kunye nale nombolo ibalula.
Ukubhalwa kwebhakhowudi kwamkelekile njengendlela yokuchonga eyongezelelweyo.
Ityhubhu mayingabi naziphene kwaye iya kuba nesiphelo esifana nomsebenzi.
Iziphelo zetyhubhu kufuneka zisikwe ngokucocekileyo kwaye zingabi namacala abukhali.
I-Chip eqengqelekayo (i-Type 1a): Uhlobo lwe-1a (ngokuthe ngqo kwintsimbi eshushu egobileyo kunye ne-chips edibeneyo) ngokuqhelekileyo inomphezulu we-chip.Le meko yomphezulu yamkelekile kwizicelo ezithile apho umgangatho ophezulu womphezulu ungafunwa.
I-Chip Rolled Chip (i-Type 1b): Uhlobo lwe-1b (olwenziwe kwintsimbi eshushu edibeneyo kunye ne-oiled kunye ne-chips ekhutshweyo) inikeza indawo ecocekileyo yezicelo ezifuna ukupeyinta okanye umgangatho ongcono wendawo.
Iityhubhu ziya kugqunywa ngefilim yeoli phambi kokuba ithunyelwe ngenqanawa ukunqanda umhlwa.
Ngaba umyalelo uchaza ukuba i-tubing ithunyelwe ngaphandlei-oyile ebuyisela umhlwa, ifilimu yee-oyile ezenzelwe ukwenziwa iya kuhlala phezu komhlaba.
Inokuthintela ngokufanelekileyo umphezulu wombhobho ukuba ungaphenduli ngomswakama kunye neoksijini emoyeni, ngaloo ndlela ugweme ukugqwala kunye nokubola.
Ngexabiso eliphantsi: Inkqubo ye-welding yensimbi eshushu eshushu yenza i-ASTM A513 Uhlobo lwe-1 lufikeleleke ngakumbi xa kuthelekiswa neemveliso ezibandayo.
Uluhlu olubanzi lwezicelo: I-ASTM A513 Uhlobo lwe-1 lufanelekile kwiinkqubo ezahlukeneyo, kubandakanywa amacandelo ezakhiwo, iifreyimu, i-shelving, kunye nokunye.Ukuguquguquka kwayo kwiindawo ezahlukeneyo kunye nemisebenzi kuyenza ibe lukhetho oludumileyo kumashishini afana neemoto, ulwakhiwo kunye noomatshini.
Ukuweldability okugqwesileyo: Ukwakhiwa kweekhemikhali ze-ASTM A513 Udidi lwe-1 lulungele ukudibanisa, kwaye lunokuthi ludityaniswe kusetyenziswa iindlela ze-welding eziqhelekileyo, okwenza kube yinto esebenzayo kwiindawo ezahlukeneyo zokuvelisa.
Amandla amahle kunye nokuqina: Nangona ingenamandla njengentsimbi yealloyi okanye iintsimbi eziphathwayo, iyahlangabezana nemfuneko yokubonelela ngamandla aneleyo kusetyenziso oluninzi lwezakhiwo kunye noomatshini.Ukuqhubela phambili, njengonyango lokushisa, kunokuphucula iimpawu zomatshini wombhobho ukuhlangabezana neemfuno ezithile.
Umphezulu Gqiba: Uhlobo lwe-1b lubonelela ngomgangatho ococekileyo, onenzuzo kwizicelo apho kufuneka ukugqiba umgangatho olungileyo kwaye apho ukupenda okanye ukulungiswa okungaphezulu kuyadingeka.
I-ASTM A513 Uhlobo loku-1 lubonelela ngolungelelwaniso olululo lweendleko, ukusebenza, kunye nokuguquguquka, oko kuyenza ifaneleke kusetyenziso oluninzi lomatshini kunye nolwakhiwo apho kufuneka iityhubhu enexabiso eliphantsi eneempawu ezilungileyo zoomatshini.
Isetyenziswe ekwakheni njengezakhiwo ezixhasayo ezifana nemiqadi kunye neentsika.
