I-ASTM A500 kunye ne-ASTM A513zombini ziyimigangatho yokuveliswa kombhobho wentsimbi yinkqubo ye-ERW.
Nangona zabelana ngeenkqubo ezithile zokuvelisa, zahlukile kakhulu ngeendlela ezahlukeneyo.
Uhlobo lwentsimbi
I-ASTM A500: Inkcazo esemgangathweni yeetyhubhu zesinyithi sekhabhoni esenziwe ngobushushu kunye nesinyithi esingenamthungo kwiindidi kunye neemilo
I-ASTM A500 inokuba yintsimbi yekhabhoni kuphela.
I-ASTM A513: Inkcazo esemgangathweni yeCarbon eWelded ekhabhoni kunye ne-Alloy Steel Mechanical Tubing
I-ASTM A513 inokuba yintsimbi yekhabhoni okanye intsimbi ye-alloy.
Uluhlu lobungakanani
Inkqubo yoMveliso
Inkqubo yoMveliso ye-ASTM A500
Umbhobho kufuneka wenziwe ngumntuinkqubo engenamthungo okanye yokuwelda.
Iityhubhu ezidityanisiweyo mazisetyenziswe ngentsimbi egoqwe ngomgca othe tyaba ngenkqubo yokudibanisa ngombane (ERW).
I-A500 idla ngokwenziwa ngentsimbi xa ishushu, ize yenziwe ngentsimbi ebandayo ize idityaniswe.
Qaphela: I-Flat-rolled ibhekisa kwinkqubo yokusebenza ngesinyithi esetyenziswa kakhulu kwintsimbi nakwezinye izinto zesinyithi.Kule nkqubo, isinyithi siqala kwimo yaso yokuqala yobukhulu (umz. ingot) size sithambe sibe ngamashiti okanye iikhoyili ngenkqubo yokuqengqeleka eshushu okanye ebandayo.
Inkqubo yoMveliso ye-ASTM A513
Iityhubhu mazibe zenziwe ngenkqubo edibeneyo yokumelana nombane kwaye mazibe zenziwe ngentsimbi eqengqelekayo eshushu okanye ebandayo njengoko kuchaziwe.
Unyango lobushushu
Unyango lobushushu lwe-ASTM A500
Iityhubhu ezikumgangatho we-ASTM A500 azidingi nyango lobushushu. Oku kungenxa yokuba i-ASTM A500 yenzelwe ukusetyenziswa kwesakhiwo, apho kugxininiswa khona kumandla okwakha aneleyo kunye nokuqina. Ezi tyhubhu zihlala ziveliswa ngokwenza ubushushu kunye nokuwelda okulandelayo, kusetyenziswa izinto zentsimbi yekhabhoni esele zinamandla kunye nokuqina.
Nangona kunjalo, kwiimeko ezithile ezithile, ukuze kufezekiswe iimpawu ezithile zoomatshini okanye ukuhlangabezana neemfuno ezithile zobugcisa, iityhubhu kunye neepayipi ze-ASTM A500 zinokusetyenziswa unyango lobushushu oluqhelekileyo okanye olunciphisa uxinzelelo, ingakumbi apho uxinzelelo olushiyekileyo lususwa emva kokuwelda.
Unyango lobushushu lwe-ASTM A513
Umgangatho we-ASTM A513 unikezela ngeentlobo ezahlukeneyo zeetyhubhu, ezinye zazo ezinokulungiswa ngobushushu ukuze kufezekiswe iipropati zoomatshini ezifunekayo.
NA(Ayifakwanga) - Ayifakwanga; ibhekisa kwimibhobho yentsimbi engakhange inyangwe ngobushushu kwimeko edibeneyo okanye etsaliweyo, oko kukuthi, ishiywe ikwimeko yayo yokuqala emva kokuwelda okanye ukuzoba. Olu nyango lusetyenziselwa usetyenziso apho kungekho tshintsho kwiimpawu zoomatshini olufunekayo ngonyango lobushushu.
I-SRA(Uxinzelelo Oluthomalalisiweyo) - Uxinzelelo Oluthomalalisiweyo; olu nyango lobushushu lwenziwa kumaqondo obushushu angaphantsi kobushushu obuphantsi obubalulekileyo bezinto, ngenjongo ephambili yokususa uxinzelelo lwangaphakathi oluveliswa ngexesha lokucubungula ityhubhu, ngaloo ndlela kuphuculwe uzinzo lwezinto kwaye kuthintelwe ukuguquka emva kokucubungula. Uxinzelelo oluthomalalisiweyo ludla ngokusetyenziswa ekucubunguleni iindawo ezichanekileyo ukuqinisekisa ukuchaneka kobukhulu kunye nokuma.
N(I-Annealed eqhelekileyo okanye eQhelekileyo) - I-annealing eqhelekileyo okanye eQhelekileyo; unyango lobushushu kumaqondo obushushu angaphezulu kobushushu obuphezulu bezinto apho ubungakanani bentsimbi bunokulungiswa khona kwaye iimpawu zayo zoomatshini kunye nokuqina kuphuculwe. I-normalizing lunyango oluqhelekileyo lobushushu olusetyenziselwa ukuphucula iimpawu zoomatshini zezinto ukuze zilungele ngakumbi imithwalo ephezulu yokusebenza.
Ukwakhiwa kweeKhemikhali kunye neePropati zoMatshini
Ityhubhu ye-ASTM A500 yenzelwe iinjongo zokwakha kwaye ineempawu ezithile zoomatshini (amandla okutsalwa, amandla okukhupha, ukunwebeka) kunye neekhemikhali.
Yaziwa ngokukwazi kwayo ukunamathela kakuhle kunye nokuqina kwayo kwaye ingasetyenziswa kwizakhiwo ezifuna umlinganiselo ophezulu wamandla nobunzima.
Kukho iintlobo ezahlukeneyo zeetyhubhu ze-ASTM A513, nganye ineempawu zayo zoomatshini nezekhemikhali zokusetyenziswa okuthile.
Umzekelo, ityhubhu yohlobo lwe-5 yimveliso yesleeve edwetshiweyo (DOM) enokumelana okuqinileyo, ukugqitywa komphezulu okungcono, kunye neempawu zoomatshini ezihambelanayo.
Iindawo eziphambili zokusetyenziswa
I-ASTM A500 isetyenziswa kakhulu kwizakhiwo ezifana nezakhiwo, iibhulorho, kunye nezinto ezixhasayo. Isetyenziswa apho kufuneka khona ulwakhiwo oluqinileyo noluqinileyo.
Kwelinye icala, i-ASTM A513 isetyenziswa kwizicelo ezifuna ukunyamezelana okuchanekileyo kunye nokugqitywa komphezulu. Ukusetyenziswa okuqhelekileyo kubandakanya iindawo zemoto kunye neendawo zoomatshini ezinokufuna ukufakwa kunye ngokuchanekileyo okukhulu.
Ixabiso
Iimveliso ze-ASTM A500 zihlala zibiza kancinci ngenxa yeemfuno zokuchaneka okuncinci kakhulu kwenkqubo yokuvelisa.
I-ASTM A513, ingakumbi i-Type 5 (DOM), inokubiza kakhulu ngenxa yokufakelwa okongeziweyo okufunekayo ukuze kulungiswe ngcono kwaye kugqitywe umphezulu.
Ngoko ke, ukhetho phakathi kwezi ntlobo zimbini zepayipi yentsimbi kufuneka lusekelwe kwiimfuno ezithile zeprojekthi.
Ukuba iprojekthi ifuna amandla nokuqina kwesakhiwo, i-ASTM A500 lukhetho olufanelekileyo ngakumbi. Ngelixa, kwizicelo ezifuna ukuchaneka okuphezulu kunye nemeko entle yomphezulu, i-ASTM A513 inokukhethwa.
