I-ASTM A500 kunye ne-ASTM A513yomibini imigangatho yokuveliswa kombhobho wensimbi ngenkqubo ye-ERW.
Nangona besabelana ngeenkqubo ezithile zokuvelisa, zahluke kakhulu ngeendlela ezininzi.
Uhlobo lwentsimbi
ASTM A500: Inkcazo esemgangathweni ye-Cold-Formed Welded kunye ne-Seamless Carbon Steel Structural Tubing kwiMijikelo kunye neeMilo
I-ASTM A500 ingaba yintsimbi yekhabhoni kuphela.
I-ASTM A513: Inkcazo esemgangathweni ye-Electric Resistance-Welded Carbon kunye ne-Alloy Steel Mechanical Tubing
I-ASTM A513 ingaba yintsimbi ye-carbon okanye i-alloy steel.
Ubungakanani Uluhlu
Inkqubo yokuVelisa
Inkqubo yokwenziwa kwe-ASTM A500
Ityhubhu iya kwenziwa ngu ainkqubo engenamthungo okanye welding.
I-Welded tubing iya kwenziwa kwi-flat-rolled steel ngenkqubo ye-electric-resistance-welding (ERW).
I-A500 idla ngokwenziwa kwintsimbi ekwimo eshushu, emva koko ibanda kwaye idityaniswe.
Qaphela: I-Flat-rolled ibhekisela kwinkqubo yokwenza isinyithi esetyenziswa ngokukodwa kwintsimbi kunye nezinye izinto zetsimbi.Kule nkqubo, isinyithi siqala ngohlobo lwaso lwesambuku sokuqala (umz. ingot) kwaye sicandwe sibe ngamashiti okanye iikhoyili ngenkqubo yokuqengqeleka eshushu okanye ebandayo.
Inkqubo yokwenziwa kwe-ASTM A513
Imibhobho iya kwenziwa yinkqubo yombane-ukumelana ne-welded kwaye iya kwenziwa kwintsimbi eshushu okanye ebandayo njengoko kuchaziwe.
Unyango lobushushu
Unyango lobushushu lwe-ASTM A500
Iibhubhu ezikumgangatho we-ASTM A500 aziqhelekanga ukuba zifune unyango lobushushu.Oku kungenxa yokuba i-ASTM A500 yenzelwe ukusetyenziswa kolwakhiwo, apho ugxininiso lukukomelela okwaneleyo kunye nokuqina.Ezi ityhubhu zidla ngokuveliswa ngokwenza okubandayo kunye nokuwelda okulandelayo, kusetyenziswa imathiriyeli ye-carbon steel esele inamandla athile kunye nokuqina.
Nangona kunjalo, kwiimeko ezithile ezithile, ukuze kuphunyezwe iimpawu ezithile zoomatshini okanye ukuhlangabezana neemfuno ezithile zobugcisa, iityhubhu kunye nemibhobho ye-ASTM A500 inokuthi ixhomekeke kunyango oluqhelekileyo okanye oluthomalalisa uxinzelelo lobushushu, ngakumbi apho uxinzelelo olushiyekileyo lususwa emva kwe-welding.
Unyango lobushushu lwe-ASTM A513
Umgangatho we-ASTM A513 ubonelela ngeentlobo ezininzi zetyhubhu, ezinye zazo ezinokunyangwa ngobushushu ukuze zifezekiseke iipropathi ezinqwenelekayo zoomatshini.
NA(Ayiphoswanga) - Ayifakwanga;ibhekiselele kwityhubhu yentsimbi engakhange iphathwe ubushushu kwimeko edityanisiweyo okanye etsaliweyo, okt, ishiywe kwimeko yayo yangaphambili emva kwe-welding okanye umzobo.Olu nyango lusetyenziselwa izicelo apho kungekho tshintsho kwiipropati zomatshini ezifunekayo ngonyango lokushisa.
I-SRA(Uxinzelelo luNcinciwe luAnealing) - Uxinzelelo lweAnnealing luthotyiwe;olu nyango lobushushu lwenziwa kumaqondo okushisa angaphantsi kweqondo lokushisa eliphantsi lezinto eziphathekayo, ngenjongo ephambili yokususa uxinzelelo lwangaphakathi olwenziwe ngexesha lokucutshungulwa kombhobho, ngaloo ndlela kuphuculwe ukuzinza kwezinto kunye nokuthintela ukuguqulwa emva kokucubungula.I-annealing ephelisa uxinezeleko idla ngokusetyenziswa ekwenziweni kwamalungu achanekileyo ukuqinisekisa ukuchaneka komda kunye nokumila.
N(Eyesiqhelo okanye eQhelekileyo eAnealed) - Ukufakwa okuqhelekileyo okanye okuqhelekileyo;unyango lobushushu kumaqondo obushushu ngaphezu iqondo eliphezulu elibalulekileyo ubushushu nto leyo ubungakanani iinkozo zentsimbi inokucocwa kwaye iimpawu zayo mechanical kunye nokuqina ngcono.Ukwenziwa kwesiqhelo lunyango oluqhelekileyo lobushushu olusetyenziselwa ukomeleza iipropathi zomatshini zemathiriyeli ukuyenza ifaneleke ngakumbi kwimithwalo yokusebenza ephezulu.
Ukubunjwa kwemichiza kunye neePropati zoomatshini
Ishubhu ye-ASTM A500 yenzelwe iinjongo zolwakhiwo kwaye inomatshini othile (amandla okuqina, amandla esivuno, ukunweba) kunye neempawu zekhemikhali.
Iyaziwa ngokuba yi-weldability elungileyo kunye ne-ductility kwaye inokusetyenziswa kwizakhiwo ezifuna umlinganiselo ophezulu wokuqina kobunzima.
Kukho iintlobo ezininzi ezahlukeneyo zetyhubhu ye-ASTM A513, nganye inomatshini wayo kunye neempawu zayo zemichiza kwizicelo ezithile.
Umzekelo, Uhlobo lwesi-5 lwetyhubhu yimveliso etsaliweyo (DOM) enokunyamezelana, ukugqiba okungcono komphezulu, kunye neempawu zoomatshini ezingaguqukiyo.
IiNdawo zeSicelo eziPhambili
I-ASTM A500 isetyenziswa ngokuqhelekileyo kwizicelo zesakhiwo ezifana nezakhiwo, iibhulorho, kunye namacandelo enkxaso.Isetyenziswa apho amandla aphezulu kunye nokwakhiwa okuqinileyo kuyadingeka.
Ngakolunye uhlangothi, i-ASTM A513 isetyenziswe kwizicelo ezifuna ukunyamezela okuchanekileyo kunye nokugqitywa kwendawo.Ukusetyenziswa okuqhelekileyo kubandakanya iinxalenye zeemoto kunye neenxalenye zoomatshini ezinokufuna ukufakwa kunye ngokuchanekileyo okugqithisileyo.
Ixabiso
Iimveliso ze-ASTM A500 ngokubanzi azibizi kakhulu ngenxa yeemfuno zokuchaneka komgangatho ophantsi wenkqubo yokuvelisa.
I-ASTM A513, ngakumbi i-Type 5 (DOM), inokubiza kakhulu ngenxa yomatshini owongezelelweyo ofunekayo ukuchaneka okungcono kunye nokugqitywa kwendawo.
Ngoko ke, ukhetho phakathi kwezi ntlobo zimbini zombhobho wensimbi kufuneka lusekelwe kwiimfuno ezithile zeprojekthi.
Ukuba iprojekthi idinga amandla okwakhiwa kunye nokuqina, i-ASTM A500 lukhetho olufanelekileyo ngakumbi.Ngelixa, kwizicelo ezifuna ukuchaneka okuphezulu kunye nemeko ephezulu yomphezulu, i-ASTM A513 inokukhethwa.
