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 lwesi-5ngaphakathi ASTM A513 umgangatho ubhekisa kwiIzotywe ngaphaya kweMandrel (DOM)imibhobho.
Ityhubhu ye-DOM iveliswa ngokuthi kuqale kwenziwe ityhubhu edityanisiweyo kwaye emva koko ibandayo izoba kwi-dies nangaphezulu kwe-mandrels ukugqibezela kunyamezelo olusondele ngakumbi kunye nokugqiba komphezulu ogudileyo xa kuthelekiswa nezinye iintlobo zetyhubhu edityanisiweyo.
Umgangatho wokwenziwa: ASTM A513
Izinto eziphathekayo: Intsimbi eshushu okanye ebandayo
Uhlobo:Uhlobo1 (1a okanye 1b), Type2, Type3, Type4, Type5, Type6.
IBakala: MT 1010, MT 1015,1006, 1008, 1009 njl.
Unyango lobushushu: NA, SRA, N.
Ubungakanani kunye nobukhulu bodonga
Imilo yecandelo elinomgongxo: Isangqa, isikwere, okanye ezinye iimilo
Ubude
Ubungakanani obupheleleyo
Iintlobo ze-ASTM A513 zihluke ngesiseko seemeko ezahlukeneyo okanye iinkqubo zombhobho wensimbi.
I-ASTM A513 uhlobo lwetyhubhu engqukuva amabakala ama-5 aqhelekileyo ngala:
1008, 1009, 1010, 1015, 1020, 1021, 1025, 1026, 1030, 1035, 1040, 1340, 1524, 4130, 4140.
Umjikelo
Isikwere okanye uxande
Ezinye iimilo
ezifana ne-streamlined, i-hexagonal, i-octagonal, ingqukuva ngaphakathi kunye ne-hexagonal okanye i-octagonal ngaphandle, i-ribbed ngaphakathi okanye ngaphandle, i-triangular, i-rectangular engqukuva, kunye neemilo zika-D.
Intsimbi eqengqelekayo eshushu okanye ebandayo
Izinto eziluhlaza zokuvelisa i-Hot-rolled okanye i-Cold-rolled Steel inokuveliswa nayiphi na inkqubo.
Intsimbi eQithiweyo: 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.
Intsimbi eBanda-Rolwe: Intsimbi epholileyo iqengqeleka ngakumbi emva kokuba izinto zipholile ukufezekisa ubungakanani obufunwayo kunye nemilo.Le nkqubo idla ngokuqhutyelwa kwiqondo lokushisa legumbi kwaye ibangele intsimbi enomgangatho ongcono wendawo kunye nemilinganiselo echanekileyo.
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.

Qaphela 1: La maxabiso asekelwe kubushushu obuqhelekileyo bokunciphisa uxinzelelo lwelitye.Kwizicelo ezithile, iipropati zinokulungelelaniswa ngothethathethwano phakathi komthengi nomvelisi.
Qaphela 2: Kwiimvavanyo ze-longitudinal strip, ububanzi becandelo le-gauge buya kuba ngokwe-A370 Annex A2, i-Steel Tubular Products, kunye nokuxhuzulwa kwepesenti ye-0.5 yeepesenti kwi-elongation esisiseko kwi-elongation nganye.1/32kwi [0.8 mm] ukuhla kobunzima bodonga ngaphantsi5/16ku [7.9 mm] ubukhulu bodonga buya kuvunyelwa.
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.

Phawula olu lwazi lulandelayo ngendlela efanelekileyo ngentonga okanye inyanda nganye.
igama lomenzi okanye ibhrendi, ubungakanani obuchaziweyo, uhlobo, inombolo yeodolo yomthengi, kunye nale nombolo ibalula.
Ukubhalwa kwebhakhowudi kwamkelekile njengendlela yokuchonga eyongezelelweyo.
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.
Enyanisweni, ngelixa i-lubricant esisiseko okanye ifilimu ye-oyile elula inokubonelela ngezinga elithile lokukhusela okwethutyana, kwizicelo ezifuna izinga eliphezulu lokukhusela, unyango olufanelekileyo lokukhusela ukubola kufuneka lukhethwe kwimeko-nge-case.
Umzekelo, kwimibhobho engcwatyiweyo, a3PE(i-polyethylene ene-three-layer) i-coating ingasetyenziselwa ukubonelela ngokhuseleko lwexesha elide lokutya;kwimibhobho yamanzi, iFBE(i-fusion-bonded epoxy powder) i-coating ingasetyenziswa, ngelixayenziwe igalatiunyango lunokuba lukhetho olusebenzayo kwiindawo apho ukukhuselwa kwi-zinc corrosion kuyadingeka.
Ngobu buchwepheshe obukhethekileyo bokukhusela i-corrosion, ubomi benkonzo yombhobho bunokwandiswa kakhulu kunye nokusebenza kwayo kugcinwe.
