Umbhobho woBubushushu obuphantsi (A333 A334 Gr.6 Gr.3)
IMIbhobho yobushushu obuphantsi
Ubungakanani bombhobho--1/4” Ngokwesiqhelo ukuya kuma-42”OD
Ukutyeba kweendonga - iShedyuli ye-10 ukuya kwi-XXH
Iintsimbi zekhabhoni ezinobushushu obuphantsi ziye zaphuhliswa ikakhulu ukuze zisetyenziswe kwisixhobo sobushushu obuphantsi kwaye ngakumbi kwiinqanawa zoxinzelelo oludityanisiweyo.
Ziyi-low-to medium-carbon (0.20 ukuya kwi-0.30%), i-manganese ephezulu (0.70 ukuya kwi-1.60%), i-silicon (0.15 ukuya kwi-0.60%) i-steels, ene-fine-grain structure kunye ne-uniform carbide dispersion.Zibonisa amandla aphakathi kunye nokuqina ukuhla ukuya ku- - 50 ° F (-46 ° C).
Ukulungiswa kweenkozo kunye nokuphucula ukubunjwa kunye ne-weldability, i-carbon steels ingaba ne-0.01 kwi-0.04% ye-columbium.Ebizwa ngokuba ziintsimbi ze-columbium, zisetyenziselwa ishafti, iifogi, iigiya, iinxalenye zoomatshini, kunye nokufa kunye neegeji.Ukuya kuthi ga kwi-0.15% sulfure, okanye i-0.045 phosphorus, ibenza basebenze ngokukhululeka, kodwa banciphisa amandla.
I-LTCS yi-Nickel esekelwe kwi-alloy plates yensimbi ngokukodwa esetyenziselwa izicelo zokushisa eziphantsi ngaphantsi kwe-150 deg F. Isetyenziswa kakhulu kulwakhiwo lwe-cryogenic lweenqanawa zasemkhathini, ukusetyenziswa kobushushu obuphantsi kwisityalo sekhemikhali esingaphantsi kwe -55 deg C.
I-SA-203 Steel Plate amaBanga A, B, D, E kunye ne-F Nickle Alloy Steel Plates.Ngobushushu obuphantsi (-150 deg F)
Ubushushu obuphantsi Iityhubhu zeCarbon Steel ASTM A334 Gr.1
I-ASTM A333——Imibhobho yentsimbi engenamthungo kunye neWelded kwiNkonzo yoBubushushu obuphantsi:
IBanga ikakhulu
iBakala 1, iBakala 3, iBakala 4, iBakala 6, iBakala 7, iBakala 8, iBakala 9, iBakala 10, iBakala 11;
Ubushushu obuphantsi carbon steel umbhobho ukucima iqondo lobushushu A3 + (30 ~ 50) ℃, ngokusebenza, idla ibekwe kumda ophezulu.Umbhobho wokushisa wokucima ubushushu obuphezulu unokwenza isantya esiphantsi, ukunciphisa i-oxidation yomhlaba, kwaye unokuphucula ukusebenza kakuhle.I-workpiece yi-uniform austenite, iya kufuna ixesha elaneleyo lokubamba.Ukuba umthamo wangempela wesithando somlilo, kuya kufuneka ukuba ufanelekile ukwandisa ixesha lokubamba.Ngaphandle koko, kunokubakho ubunzima obaneleyo ngenxa yokufudumeza okungalinganiyo okubangelwa yinto.Nangona kunjalo, ixesha lokubamba lide kakhulu, liya kubonakala kwakhona iinkozo ezirhabaxa, i-oxidation kunye ne-decarbonization yeengxaki ezinzulu ezichaphazela umgangatho wokucima.Sikholelwa ukuba ukuba i-furnace efakiweyo inkulu kunamaxwebhu enkqubo, ukufudumeza ixesha lokubamba ukuba kwandiswe 1/5.
Umbhobho ophantsi we-carbon steel pipe ngenxa yokuqina okuphantsi, kufuneka wamkele izinga lokupholisa elikhulu le-10% yesisombululo setyuwa.I-workpiece emanzini, kufuneka ibe lukhuni, kodwa ayigodoli, ukuba i-45 # echanekileyo yentsimbi epholileyo kwi-brine, kunokwenzeka ukuqhekeka kwe-workpiece, oku kungenxa yokuba xa i-workpiece ipholile ukuya malunga ne-180 ℃, i-austenite iguqulelwe ngokukhawuleza kumzimba wehashe. izicubu ezibangelwa luxinzelelo olugqithisileyo ngenxa.Ngoko ke, xa intsimbi yokucima kunye neyokufudumala ipholile ngokukhawuleza kolu luhlu lobushushu, indlela kufuneka ithathwe ukupholisa ngokukhawuleza.
Njengoko ubushushu bamanzi kunzima ukubuqonda, amava okuphendula ekusebenzeni, xa amanzi eyeka ukudiza izinto zakudala, unokunkcenkceshela aphole (umz. isipholile se-oyile sinokuba ngcono).Ukongezelela, i-workpiece emanzini, isenzo esifanelekileyo kufuneka siqhubeke ngokuhambelana nejometri ye-workpiece, njengomsebenzi oqhelekileyo.Indawo yokupholisa emileyo kunye nesixhobo sokusebenza esimileyo, esikhokelela kubunzima obungalinganiyo, uxinzelelo olungalinganiyo lushiya inguqu enkulu yendawo yokusebenza, kunye nokuqhekeka.
