Imilo yeCandelo eliHoli
Inokuba njaloingqukuva, isikwere, uxande, okanye ezinye iimilo ezikhethekileyo zesakhiwo.
Eli nqaku ligxininisa kwiimfuno ze-ASTM A500 zentsimbi yesakhiwo esijikelezayo.
Ukuhlelwa kweBanga
I-ASTM A500 ihlela umbhobho wentsimbi ngokwamanqanaba amathathu,iBanga B, ibakala C, kunye nebakala D.
Kuyaphawuleka ukuba iinguqulelo zangaphambili ze-ASTM A500 nazo zineBanga A, elasuswa kuhlobo lwamva nje luka-2023.
Ubungakanani Uluhlu
Kwiityhubhu ezinobubanzi obungaphandle ≤ 2235mm [88in] kunye nobukhulu bodonga ≤ 25.4mm [1in].
Iimpahla ezingekasilwa
Intsimbi iya kwenziwa yinye okanye ngaphezulu kwezi nkqubo zilandelayo:i-oksijeni esisiseko okanye isithando somlilo sombane.
Inkqubo ye-Oxygen esisiseko: Le yindlela yanamhlanje ekhawulezayo yokuveliswa kwentsimbi, enciphisa umxholo wekhabhoni ngokuvuthela ioksijini kwintsimbi yehagu etyhidiweyo, ngelixa isusa ezinye izinto ezingafunekiyo ezifana nesulfure kunye nephosphorus.Kufanelekile ukuveliswa ngokukhawuleza kwezinto ezininzi zetsimbi.
Inkqubo yesithando soMbane: Inkqubo yeSithando soMbane isebenzisa i-arc yombane ephezulu yokushisa ukunyibilikisa i-scrap kunye nokunciphisa ngokuthe ngqo isinyithi, kwaye iluncedo ngokukhethekileyo ekuveliseni amabakala akhethekileyo kunye nokulawula iingoma ze-alloy, kunye nokuveliswa kwebhetshi encinci.
Iindlela Zokuvelisa
Inkqubo engenamthungo okanye i-welding.
I-Welded tubing iya kwenziwa kwi-flat-rolled steel ngenkqubo ye-electric-resistance-welding (ERW).I-weld seam kufuneka idityaniswe ukuze kuqinisekiswe amandla ombhobho.
Imibhobho eveliswa yinkqubo ye-welding ngokuqhelekileyo ayinayo i-weld yangaphakathi isuswe.
Tube End Type
Ukuba ayifunwa ngokuthe ngqo, iityhubhu zesakhiwo kufuneka zibeiphelilekwaye ucocekile kwii-burrs.
Unyango lobushushu
IBanga B kunye neBanga C
Inokukhutshwa okanye ithotywe uxinzelelo.
I-Anealing ifezekiswa ngokufudumeza ityhubhu kwiqondo lobushushu eliphezulu kwaye emva koko uyipholise kancinci.I-Annealing iphinda ihlengahlengise i-microstructure yezinto zokuphucula ukuqina kwayo kunye nokufana.
Ukunciphisa uxinzelelo ngokuqhelekileyo kwenziwa ngokufudumeza imathiriyeli kwiqondo lobushushu elisezantsi (elihlala lingaphantsi kunelo lokucoca) emva koko uyibambe ixesha elithile kwaye emva koko uyipholise.Oku kunceda ukuthintela ukuphazamiseka okanye ukuphuka kwezinto ngexesha lemisebenzi elandelayo efana ne-welding okanye ukusika.
IBanga D
Unyango lobushushu luyafuneka.
Kufuneka kwenziwe kwiqondo lobushushu ubuncinaneI-1100 ° F (590 ° C) ngeyure enye nge-25 mm ubukhulu bodonga.
Ukuqulunqwa kwemichiza ye-ASTM A500
Indlela yovavanyo: ASTM A751.
IiMfuno zeTensile ze-ASTM A500
Imizekelo iya kuhlangabezana neemfuno ezisebenzayo ze-ASTM A370, iSihlomelo A2.
Uvavanyo lokucaba
IMibhobho yeZakhiwo eDidiyelweyo
WeldduncedotEst: Ukusebenzisa i-specimen ubuncinane i-intshi ezi-4 (i-100 mm) ubude, thambisa umboniso nge-weld kwi-90 ° ukuya kwicala lokulayisha kude kube umgama phakathi kwamacwecwe ungaphantsi kwe-2/3 yobubanzi obungaphandle bombhobho.umfuziselo awuyi kuqhekeka okanye wophuke ngaphakathi okanye ngaphandle komphezulu ngexesha lenkqubo.
Uvavanyo lwe-ductility yombhobho: qhubeka uhlambulule i-specimen kude kube umgama phakathi kwamacwecwe ungaphantsi kwe-1/2 ye-diameter yangaphandle yombhobho.ngeli xesha, umbhobho akufanele ube nokuqhekeka okanye ukuphuka kwiindawo zangaphakathi nangaphandle.
IngqibelelotEst: Qhubeka ulula umfuziselo de kwenzeke ukwaphuka okanye de iimfuno zobunzima bodonga zihlangatyezwe.Ukuba ubungqina be-ply peeling, izinto ezingazinzanga, okanye i-welds engaphelelanga ifunyenwe ngexesha lovavanyo lwe-flattening, i-specimen iya kugwetywa ngokunganelisiyo.
Imibhobho yoLwakhiwo eRound engenamthungo
Ubude boMfanekiso: Ubude bomzekelo osetyenziselwa uvavanyo abuyi kuba ngaphantsi kwe-2 1/2 kwi-(65 mm).
Uvavanyo lweDuctility: Ngaphandle kokuqhekeka okanye ukuqhekeka, i-specimen iyancipha phakathi kwamacwecwe ahambelanayo de umgama phakathi kwamacwecwe ungaphantsi kwexabiso elithi "H" elibalwe ngolu hlobo lulandelayo:
H=(1+e)t/(e+t/D)
H = umgama phakathi kweepleyiti ezicaba, ngaphakathi [mm],
e= deformation ngobude beyunithi nganye (ngokuqhubekayo kwibakala elinikiweyo lentsimbi, 0.07 kwiBanga B, kunye no-0.06 kwiBanga C),
t= ubukhulu bodonga obuchaziweyo betyhubhu, ngaphakathi. [mm],
D = icaciswe ngaphandle kwedayamitha yetyhubhu, ngaphakathi [mm].
IngqibelelotEst: Qhubeka ucoca isampuli de isampuli iphuke okanye iindonga ezichaseneyo zesampulu zihlangane.
Ukusilelacriteria: I-laminar peeling okanye izinto ezibuthathaka ezifunyenwe kulo lonke uvavanyo oluthe tyaba luya kuba zizizathu zokukhatywa.
Uvavanyo oluvuthayo
Uvavanyo oluvuthayo luyafumaneka kwiityhubhu ezijikelezayo ≤ 254 mm (10 in) ububanzi, kodwa akunyanzelekanga.
Unyamezelo lweDimensional ye-ASTM A500
Ukumakishwa kweThubhu
Olu lwazi lulandelayo kufuneka lubandakanywe:
Igama lomenzi: Oku kunokuba ligama elipheleleyo lomenzi okanye isifinyezo.
Uphawu okanye uphawu loRhwebo: Igama lebrendi okanye uphawu lwentengiso olusetyenziswa ngumenzi ukwahlula iimveliso zalo.
Iinkcukacha zoMyili: ASTM A500, ekungafunekiyo iquke unyaka wokupapashwa.
Ileta yeBanga: B, C okanye ibakala D.
Kwiityhubhu zesakhiwo ≤ 100mm (4in) ububanzi, iilebula zingasetyenziselwa ukuphawula ulwazi lokuchongwa ngokucacileyo.
