Ukuhlukaniswa kusekelwe ezimweni ezahlukene noma izinqubo zepayipi lensimbi.
Ukuhlukaniswa Kwebanga
I-ASTM A513 ingaba yinsimbi ye-carbon noma i-alloy, kuye ngohlelo lokusebenza lwangempela.
Insimbi Yekhabhoni
MT 1010, MT 1015, MT X 1015, MT 1020, MT X 1020.
1006, 1008, 1009, 1010, 1012, 1015, 1016, 1017, 1018, 1019, 1020, 1021, 1022, 1023, 1024, 10203, 1025,1 35, 1040, 1050, 1060, 1524.

I-ASTM A513 Ubukhulu Ububanzi
Umumo Wesigaba Esingenalutho
Umjikelezo
Isikwele noma unxande
Ezinye izimo
okufana ne-streamlined, i-hexagonal, i-octagonal, eyindilinga ngaphakathi kanye ne-hexagonal noma i-octagonal ngaphandle, izimbambo ngaphakathi noma ngaphandle, unxantathu, unxande oyindilinga womumo no-D.
Ama-Raw material
Insimbi ingenziwa nganoma iyiphi inqubo.
Ukuncibilika okuyinhloko kungase kuhlanganise ukucwenga okuhlukile noma ukucwengwa futhi kungase kulandelwe ukuncibilika kwesibili, okufana ne-electro slag noma i-vacuum-arc remelting.
Insimbi ingaphonswa ngama-ingots noma i-strand cast.
Izinqubo Zokukhiqiza ze-ASTM A513
Amashubhu azokwenziwa yi-i-electric-resistance-welded (ERW)inqubo futhi izokwenziwa ngensimbi egoqelwe eshisayo noma ebandayo njengoba kucacisiwe.
Ipayipi le-ERW inqubo yokwenza i-weld ngokugoqa insimbi ibe isilinda futhi ifake ukumelana nokucindezela ngobude bayo.
Insimbi Egoqwe Okushisayo: Enkambweni yokukhiqiza, insimbi eshisayo iqala ukushisa emazingeni okushisa aphezulu, okuvumela ukuba insimbi igoqwe esimweni sepulasitiki, okwenza kube lula ukushintsha ukuma nobukhulu bensimbi.Ekupheleni kwenqubo yokugoqa okushisayo, impahla ivamise ukukalwa futhi ikhubazekile.
Insimbi Egoqwe Ngamakhaza: Insimbi egoqwe ebandayo igoqeka ngokuqhubekayo ngemva kokuba impahla ipholile ukuze kuzuzwe usayizi nokuma okufunayo.Le nqubo ngokuvamile yenziwa ekamelweni lokushisa futhi iphumela kunsimbi enekhwalithi engcono yangaphezulu kanye nobukhulu obunembe kakhudlwana.
Ukwelashwa Okushisayo
Uma isimo sokushisa singacacisiwe, ithubhu ingase inikezwe esimweni se-NA.
Uma ukwelashwa kokugcina okushisayo kucacisiwe, i-oxide eqinile ijwayelekile.
Uma kucacisiwe indawo engenawo oksijini, ishubhu lingase likhishwe ngokugqamile noma lifakwe emanzini anosawoti ngokukhethwa komkhiqizi.
Ukuphatha Seam Welding
Ama-welds angaphandle kufanele ahlanzwe
Amashisela angaphakathi azoba nezidingo ezihlukene zobude kuye ngohlobo.
Izidingo ezithile zingatholakala ku-ASTM A513, isigaba 12.3.
Ukwakhiwa Kwekhemikhali kwe-ASTM A513
Insimbi kufanele ihambisane nezidingo zokwakheka kwamakhemikhali ezishiwo kuThebula 1 noma Ithebula 2.
Uma amamaki ensimbi ye-carbon e-odwa kusukela ezingeni elijwayelekile, akuvumelekile ukunikeza amamaki e-alloy adinga ngokukhethekile ukwengezwa kwanoma iyiphi i-elementi ngaphandle kwalawo asohlwini lwamaThebula I no-2.
Uma lingekho ibanga elishiwo, amabanga MT 1010 kuya ku-MT 1020 ayatholakala.
Izakhiwo Zemishini ye-ASTM A513
Ukuhlolwa kwe-tensile kuzokwenziwa kanye endaweni ngayinye.
Lapho "Izakhiwo Ezidingekayo Eziqinile" zicaciswa ku-Oda Lokuthenga, amashubhu ayindilinga azohambisana nezimfuneko eziqinile hhayi nemikhawulo yokuqina eboniswe kuThebula lesi-5.
Ukuhlolwa kokuqina
I-1% yawo wonke amashubhu esakhiweni ngasinye futhi angabi ngaphansi kwamashubhu ama-5.
Ukuhlola Ukucaba
Amashubhu ayindilinga namashubhu akha ezinye izimo lapho eyindilinga ayasebenza.
Akukho kuvulwa ku-weld okuzokwenzeka kuze kube yilapho ibanga phakathi kwamapuleti lingaphansi kwezingxenye ezimbili kwezintathu zobubanzi bangaphandle bangaphandle beshubhu.
Akukho ukuqhekeka noma ukuqhekeka kwensimbi eyisisekelo okuzokwenzeka kuze kube yilapho ibanga phakathi kwamapuleti lingaphansi kwengxenye eyodwa kwezintathu yobubanzi bangaphandle bangempela beshubhu kodwa kungabi ngaphansi kokuphindwe kahlanu kogqinsi lodonga lwamashubhu.
Ubufakazi be-lamination noma izinto ezishisiwe ngeke zithuthuke ngesikhathi senqubo yokwenza isicaba, futhi i-weld ngeke ibonise amaphutha alimazayo.
Qaphela: Uma ishubhu yesilinganiso se-D-to-t ephansi ihlolwa, ngenxa yokuthi ubunzima obubekwe ngenxa yejiyomethri buphezulu ngokungafanele endaweni engaphakathi endaweni yehora lesithupha neleshumi nambili, imifantu kulezi zindawo ngeke ibe yisizathu sokwaliwa uma Isilinganiso se-D-to-t singaphansi kuka-10.
Ukuhlolwa kwe-Flaring
Amashubhu ayindilinga namashubhu akha ezinye izimo lapho eyindilinga ayasebenza.
Ingxenye yeshubhu ecishe ibe ngu-4 ku-[100 mm] ubude izoma ivutha ngethuluzi eline-engeli ehlanganisiwe engu-60 ° kuze kube yilapho ishubhu emlonyeni we-flare inwetshiwe ngamaphesenti angu-15 obubanzi bangaphakathi, ngaphandle kokuqhekeka noma ukubonisa. amaphutha.
I-Hydrostatic Test Round Tubing
Wonke amashubhu azonikezwa ukuhlolwa kwe-hydrostatic.
Gcina ingcindezi encane yokuhlolwa kwamanzi ingekho ngaphansi kwama-5s.
Ingcindezi ibalwa njenge:
P=2St/D
P= ubuncane bengcindezi yokuhlolwa kwe-hydrostatic, i-psi noma i-MPa,
S= ukucindezeleka kwe-fiber okuvumelekile kwe-14,000 psi noma i-96.5 MPa,
t= ubukhulu bodonga olucacisiwe, ngaphakathi noma mm,
D= kucaciswe ububanzi bangaphandle, in. noma mm.
Ukuhlola Ugesi Okungabhubhisi
Kuyinhloso yalokhu kuhlola ukwenqaba amashubhu aqukethe izici ezilimazayo.
Ishubhu ngalinye lizohlolwa ngokuhlolwa kukagesi okungangonakali ngokuhambisana ne-Practice E213, Practice E273, Practice E309, noma Practice E570.

Ukubukeka
Ishubhu ngeke ingabi nasici futhi izoba nesiphetho esifana nomsebenzi.
Ukugqoka
Amashubhu kufanele ambozwe ngefilimu yamafutha ngaphambi kokuthunyelwa ukuze kuvinjwe ukugqwala.
Ivimbela ukugqwala ukuthi kwenzeke ngesikhathi esifushane.
Uma ngabe i-oda licacisa ukuthi amashubhu athunyelwe ngaphandle kowoyela ovimbela ukugqwala, ifilimu yamafutha azokwenziwa ngengozi izohlala phezulu.
Ukumaka
Ingaphezulu lensimbi limakwa kusetshenziswa indlela efanelekile futhi liqukethe imininingwane elandelayo:
Igama lomkhiqizi nomauphawu
