ASTM A500 uye ASTM A513ese ari maviri zviyero zvekugadzirwa kwesimbi pombi neERW maitiro.
Kunyangwe vachigovana mamwe maitiro ekugadzira, ivo vanosiyana zvakanyanya munzira dzinoverengeka.
Simbi Type
ASTM A500: Yakajairwa Kutsanangurwa kweCold-Yakaumbwa Welded uye isina Seamless Carbon Steel Structural Tubing mumaRounds uye Shapes
ASTM A500 inogona kungova kabhoni simbi.
ASTM A513: Yakajairwa Kutsanangurwa kweMagetsi-Resistance-Welded Carbon uye Alloy Steel Mechanical Tubing

Manufacturing Process
ASTM A500 Manufacturing Process
Iyo tubing ichagadzirwa naisina musono kana welding process.
Welded tubing ichagadzirwa kubva simbi-yakatenderedzwa nemagetsi-resistance-welding (ERW) process.
A500 inowanzogadzirwa kubva kusimbi munzvimbo inopisa-yakaputirwa, uye inotonhora-yakaumbwa uye yakasungirirwa.
Cherechedza: Flat-yakakungurutswa inoreva nzira yekugadzira simbi iyo inonyanya kushandiswa kune simbi uye zvimwe zvinhu zvesimbi.Mukuita uku, simbi inotanga muhuwandu hwayo hwepakutanga (eg ingot) uye inopepetwa kuita mapepa kana makoiri kuburikidza nekupisa kana kutonhora kukunguruka.
ASTM A513 Manufacturing Process
Machubhu achagadzirwa nemagetsi-resistance-welded process uye achagadzirwa kubva kunopisa- kana kutonhora-yakakungurutswa simbi sezvakatsanangurwa.
Kupisa Kurapa
ASTM A500 Heat Treatment
Machubhu ari muASTM A500 akajairwa haawanzo kuda kurapwa kwekupisa.Izvi zvinodaro nekuti ASTM A500 inoitirwa kunyanya kushandiswa kwechimiro, uko kusimbiswa kuri pane yakakwana simba rechimiro uye kuoma.Aya machubhu anowanzo kugadzirwa nekutonhora kuumba uye kunotevera welding, uchishandisa kabhoni simbi zvinhu izvo zvatova nesimba uye kuoma.
Nekudaro, mune zvimwe zviitiko, kuitira kuti uwane mamwe ma mechanika ezvivakwa kana kusangana nezvinodiwa zvehunyanzvi, machubhu nemapombi eASTM A500 anogona kunge ari pasi pekujaira kana kusagadzikana-kubvisa kupisa kupisa, kunyanya uko kusara kwekushushikana kunobviswa mushure mewelding.
ASTM A513 Kupisa Kurapa
Iyo ASTM A513 yakajairwa inopa akati wandei marudzi echubhu, mamwe acho anogona kunge achidziya-kurapwa kuti awane anodiwa emuchina zvivakwa.
NA(Haisi Kuwedzerwa) - Haina kuverengerwa;inoreva simbi tubing isina kupisa mukupisa kana yakadhirowewa mamiriro, kureva, inosiiwa muchimiro chayo chepakutanga mushure mekunama kana kudhirowa.Mushonga uyu unoshandiswa kune zvikumbiro apo pasina shanduko mune zvemagetsi zvinhu zvinodiwa nekupisa kurapwa.
SRA(Stress Relieved Annealed) - Stress Relieved Annealing;kupisa uku kunoitwa pakupisa kunowanikwa pasi pekushisa kwakadzika kwechinyorwa, nechinangwa chikuru chekubvisa kushushikana kwemukati kunogadzirwa panguva yekugadziriswa kwechubhu, nokudaro kuvandudza kugadzikana kwezvinhu uye kudzivirira deformation mushure mekugadzirisa.Annealing inobvisa kushushikana kunowanzo shandiswa mukugadziridza kwezvikamu zvakaringana kuti ive nechokwadi chekururama kwedimensional uye chimiro.
N(Normalized kana Normalized Annealed) - Yakajairika kana yakajairika annealing;kupisa kupisa pakupisa kwepamusoro kwepamusoro-soro tembiricha yezvinhu izvo saizi yesimbi inogona kunatswa uye maitiro ayo emagetsi uye kusimba kunovandudzwa.Normalizing yakajairika kupisa kupisa kunoshandiswa kusimudzira ma mechanic zvimiro zvechinhu kuti chiite chakakodzera kune yakakwira mitoro yekushanda.
Kemikari Inoumbwa uye Mechanical Properties
ASTM A500 tubing yakagadzirirwa zvimiro uye ine chaiyo mechanika (tensile simba, goho simba, elongation) uye makemikari zvimiro.
Iyo inozivikanwa nekunaka kwayo weldability uye ductility uye inogona kushandiswa muzvimiro zvinoda yakakwirira simba-ku-huremu reshiyo.
Kune akati wandei akasiyana marudzi eASTM A513 tubing, imwe neimwe iine yayo mechanika uye makemikari zvimiro zvekushandisa chaiko.
Semuyenzaniso, Type 5 tubing chigadzirwa chakadhonzwa (DOM) chine kushivirira kwakasimba, kupera kuri nani kwepamusoro, uye zvimwe zvinowirirana zvemichina.
Main Application Areas
ASTM A500 inowanzoshandiswa mukugadzirwa kwemaitiro sezvivakwa, mabhiriji, uye zvikamu zvekutsigira.Inoshandiswa apo simba repamusoro uye kuvaka kwakasimba kunodiwa.
ASTM A513, kune rumwe rutivi, inoshandiswa mumashandisirwo anoda yakakwirira-chaiyo kushivirira uye kupera kwepasi.Kushandiswa kwakajairwa kunosanganisira zvikamu zvemotokari uye zvikamu zvemakanika izvo zvingangoda kuiswa pamwe nekunyanya kurongeka.
Price
ASTM A500 zvigadzirwa zvinowanzo kudhura zvakanyanya nekuda kweiyo isinganyanyi kuomesesa dimensional kurongeka zvinodiwa zvekugadzira maitiro.
ASTM A513, kunyanya Type 5 (DOM), inogona kudhura zvakanyanya nekuda kwekuwedzera machining anodiwa kuti anyatso kunyatso uye kupera kwepasi.
Nokudaro, sarudzo pakati pemhando mbiri idzi dzepombi yesimbi inofanira kunge yakavakirwa pane zvakakosha zvepurojekiti.
Kana iyo purojekiti ichida kusimba kwesimba uye kusimba, ASTM A500 isarudzo yakakodzera.Nepo, kune maapplication anoda kurongeka kwepamusoro uye yakanakisa mamiriro epamusoro, ASTM A513 inogona kusarudzwa.
