I-ASTM A500 ne-ASTM A513womabili amazinga okukhiqizwa kwepayipi lensimbi ngenqubo ye-ERW.
Nakuba behlanganyela izinqubo ezithile zokukhiqiza, behluka kakhulu ngezindlela eziningi.
Uhlobo Lwensimbi
I-ASTM A500: Ukucaciswa Okujwayelekile Kweshubhu Yensimbi Eyinsimbi Ebandayo Eyakheke Ngokubandayo futhi Engenamthungo kumaRounds and Shapes
I-ASTM A500 ingaba yinsimbi ye-carbon kuphela.
I-ASTM A513: Ukucaciswa Okujwayelekile Kwe-Electric-Resistance-Welded Carbon kanye ne-Alloy Steel Mechanical Tubing
I-ASTM A513 ingaba yinsimbi ye-carbon steel noma i-alloy steel.
Ububanzi besayizi
Inqubo Yokukhiqiza
I-ASTM A500 Inqubo Yokukhiqiza
I-tubing izokwenziwa ngu-ainqubo Seamless noma Welding.
Amashubhu ashiselwe kufanele enziwe ngensimbi egoqelwe phansi ngenqubo ye-electric-resistance-welding (ERW).
I-A500 ivamise ukwakhiwa ngensimbi esimweni esishisayo, bese ibanda futhi ishiselwe.
Qaphela: I-flat-rolled isho inqubo yokusebenza kwensimbi esetshenziswa ngokuyinhloko ensimbi nezinye izinto zensimbi.Kule nqubo, insimbi iqala ngesimo sayo sokuqala esiyinqwaba (isb. ingot) bese isicaba ibe amashidi noma amakhoyili ngenqubo yokuginqika eshisayo noma ebandayo.
I-ASTM A513 Inqubo Yokukhiqiza
Amashubhu azokwenziwa ngenqubo kagesi-ukumelana ne-welded futhi azokwenziwa ngensimbi eshisayo noma ebandayo njengoba kucacisiwe.
Ukwelashwa Kokushisa
Ukwelashwa Kokushisa kwe-ASTM A500
Amashubhu asezingeni le-ASTM A500 awavamisile ukudinga ukwelashwa ngokushisa.Lokhu kungenxa yokuthi i-ASTM A500 ihloselwe ukusetshenziswa kwesakhiwo, lapho kugcizelelwa khona emandleni okwanele esakhiwo kanye nokuqina.Lawa mashubhu ngokuvamile akhiqizwa ukwakheka okubandayo nokushisela okulandelayo, kusetshenziswa impahla ye-carbon steel esevele inamandla athile kanye nokuqina.
Kodwa-ke, ezimweni ezithile ezithile, ukuze kuzuzwe izakhiwo ezithile zemishini noma ukuhlangabezana nezidingo ezithile zobuchwepheshe, amashubhu namapayipi e-ASTM A500 angase abhekane nokwelashwa okushisa okujwayelekile noma okudambisa ingcindezi, ikakhulukazi lapho ukucindezeleka okuyinsalela kususwa ngemva kokushiselwa.
Ukwelashwa Kokushisa kwe-ASTM A513
Izinga le-ASTM A513 linikeza izinhlobo ezimbalwa zamashubhu, ezinye zazo ezingase ziphathwe ngokushisa ukuze kuzuzwe izakhiwo ezifiselekayo zemishini.
NA(Akunanyathiselwe) - Ayifakwanga;ibhekisela kumashubhu ensimbi angazange aphathwe ngokushisa esimweni esishiselwe noma esidonswe, okungukuthi, ashiywe esimweni sawo sokuqala ngemva kokushisela noma ukudweba.Lokhu kwelashwa kusetshenziselwa izinhlelo zokusebenza lapho kungekho shintsho ezicini zemishini edingekayo ngokwelashwa kokushisa.
I-SRA(Ukucindezelwa Kwehlisiwe Kwengeziwe) - I-Stress Reeyed Annealing;lokhu kwelashwa kokushisa kwenziwa emazingeni okushisa angaphansi kwezinga lokushisa eliphansi elibucayi lezinto ezibonakalayo, ngenhloso eyinhloko yokususa ukucindezeleka kwangaphakathi okukhiqizwa ngesikhathi sokucutshungulwa kwe-tube, ngaleyo ndlela kuthuthukiswe ukuzinza kwezinto kanye nokuvimbela ukuguqulwa ngemva kokucubungula.I-anneal eqeda ingcindezi ngokuvamile isetshenziswa emshinini wezingxenye ezinembayo ukuze kuqinisekiswe ukunemba kobukhulu kanye nokwakheka.
N(I-Normalized or Normalized Annealed) - I-annealed Normalized noma evamile;ukwelashwa okushisa emazingeni okushisa angaphezu kwamazinga okushisa aphezulu abalulekile ezinto lapho usayizi wokusanhlamvu wensimbi ungacwengwa futhi izakhiwo zayo zemishini nokuqina kuthuthukiswe.I-normalizing iwukwelashwa okuvamile kokushisa okusetshenziselwa ukuthuthukisa izici zemishini zento esebenzayo ukuyenza ifaneleke kakhulu imithwalo yokusebenza ephezulu.
Ukubunjwa Kwamakhemikhali kanye Nezakhiwo Zemishini
Ishubhu ye-ASTM A500 yakhelwe izinjongo zesakhiwo futhi inomshini othize (amandla aqinile, amandla esivuno, ukuphakama) kanye nezakhiwo zamakhemikhali.
Iyaziwa ngokushisela kwayo okuhle kanye ne-ductility futhi ingasetshenziswa ezakhiweni ezidinga izilinganiso eziphezulu zamandla kuya kwesisindo.
Kunezinhlobo eziningana ezihlukene zamashubhu e-ASTM A513, ngayinye inezakhiwo zayo zokuwumshini namakhemikhali ezisetshenziswayo ezithile.
Isibonelo, ishubhu yohlobo 5 iwumkhiqizo womkhono odwetshiwe (i-DOM) onokubekezelelana okuqinile, ukuqedwa okungcono kwengaphezulu, kanye nezakhiwo ezingaguquki.
Izindawo Zokusebenza Eziyinhloko
I-ASTM A500 ivame ukusetshenziswa ezinhlelweni zesakhiwo ezifana nezakhiwo, amabhuloho, nezingxenye zokusekela.Isetshenziswa lapho amandla aphezulu kanye nokwakhiwa okuqinile kuyadingeka.
Ngakolunye uhlangothi, i-ASTM A513 isetshenziswa ezinhlelweni ezidinga ukubekezelelana okunembayo nokuqedwa kwendawo.Ukusetshenziswa okuvamile kufaka izingxenye zezimoto nezingxenye zemishini ezingase zidinge ukuhlanganiswa ngokunemba okukhulu.
Inani
Imikhiqizo ye-ASTM A500 ivamise ukubiza kancane ngenxa yezidingo zokunemba ezinobukhulu obuncane benqubo yokukhiqiza.
I-ASTM A513, ikakhulukazi i-Type 5 (DOM), ingabiza kakhulu ngenxa yomshini owengeziwe odingekayo ukuze kube nokunemba okungcono nokuqedwa kwendawo.
Ngakho-ke, ukukhetha phakathi kwalezi zinhlobo ezimbili zamapayipi ensimbi kufanele kusekelwe ezidingweni ezithile zephrojekthi.
Uma iphrojekthi idinga amandla esakhiwo nokuqina, i-ASTM A500 iyisinqumo esifaneleka kakhudlwana.Nakuba, ngezinhlelo zokusebenza ezidinga ukunemba okuphezulu nesimo esihle kakhulu sendawo, i-ASTM A513 ingakhethwa.
Amathegi: ASTM a500 vs a513, astm a500, astm a513, carbon steel tube.
