Insimbi ye-ASTM A513iyipayipi yensimbi ye-carbon ne-alloy kanye neshubhu eyenziwe ngensimbi egoqwe ngokushisayo noma ebandayo njengempahla eluhlaza ngenqubo ye-resistance welding (ERW), esetshenziswa kakhulu kuzo zonke izinhlobo zezakhiwo zemishini.
Uhlobo 5ngaphakathi kwe-ASTM A513 ejwayelekile ibhekisela kuI-Drawn Over Mandrel (DOM)ishubhu.
Amashubhu e-DOM akhiqizwa ngokuqala kwakhe ishubhu elishiselwe bese kubanda ukulidweba kuma-dies nangaphezulu kwama-mandrels ukuze aqedele ukubekezelelana okuseduze kanye nokuqedwa kwendawo okushelelayo uma kuqhathaniswa nezinye izinhlobo zamashubhu ashiselwe.
Izinga lokwenziwa: ASTM A513
Material: Insimbi egoqelwe ngokushisayo noma egoqekile
Uhlobo:Uhlobo1 (1a noma 1b), Type2, Type3, Type4, Type5, Type6.
Ibanga: MT 1010, MT 1015,1006, 1008, 1009 njll.
Ukwelashwa kokushisa: NA, SRA, N.
Usayizi nokuqina kodonga
Umumo wesigaba esingenalutho: Umjikelezo, isikwele, noma ezinye izimo
Ubude
Inani Eliphelele
Izinhlobo ze-ASTM A513 zihlukaniswa ngesisekelo sezimo noma izinqubo ezahlukene zepayipi lensimbi.
I-ASTM A513 uhlobo lweshubhu eliyindilinga 5 amamaki ajwayelekile yilawa:
1008, 1009, 1010, 1015, 1020, 1021, 1025, 1026, 1030, 1035, 1040, 1340, 1524, 4130, 4140.
Umjikelezo
Isikwele noma unxande
Ezinye izimo
njengokulandelaniswa, okuyi-hexagonal, i-octagonal, eyindilinga ngaphakathi kanye ne-hexagonal noma i-octagonal ngaphandle, izimbambo ngaphakathi noma ngaphandle, unxantathu, unxande oyindilinga, kanye nokwakheka kuka-D.
Insimbi egoqelwe ngokushisayo noma egoqekile
Izinto ezisetshenziswayo zokukhiqiza i-Hot-rolled or Cold-rolled Steel zingenziwa nganoma iyiphi inqubo.
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.
Amashubhu azokwenziwa yi-i-electric-resistance-welded (ERW)inqubo.
Ipayipi le-ERW inqubo yokwenza i-weld ngokugoqa insimbi ibe isilinda futhi ifake ukumelana nokucindezela ngobude bayo.
Insimbi kufanele ihambisane nezidingo zokwakheka kwamakhemikhali ezishiwo kuThebula 1 noma Ithebula 2.

Inothi 1: Lawa manani asekelwe emazingeni okushisa ajwayelekile okwehlisa ingcindezi.Ezinhlelweni ezithile, izakhiwo zingalungiswa ngokuxoxisana phakathi komthengi nomkhiqizi.
Inothi 2: Ekuhlolweni kwe-longitudinal strip, ububanzi besigaba segeji buzohambisana ne-A370 Annex A2, Steel Tubular Products, futhi kudonswe amaphuzu angu-0.5 ekhulwini kusukela kubude obuncane obuyisisekelo ngayinye.1/32ngokuncipha okungu-[0.8 mm] kokujiya kodonga ngaphansi5/16ku- [7.9 mm] ukujiya kodonga kuyovunyelwa.
I-1% yawo wonke amashubhu esakhiweni ngasinye futhi angabi ngaphansi kwamashubhu ama-5.
Amashubhu ayindilinga namashubhu akha ezinye izimo lapho eyindilinga ayasebenza.
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.
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.

Maka ulwazi olulandelayo ngendlela efanele kudondolo noma inqwaba.
igama lomkhiqizi noma umkhiqizo, usayizi oshiwo, uhlobo, inombolo ye-oda lomthengi, kanye nale nombolo ecacisiwe.
Ibhakhodi iyamukeleka njengendlela yokuhlonza eyengeziwe.
Amashubhu kufanele ambozwe ngefilimu yamafutha ngaphambi kokuthunyelwa ukuze kuvinjwe ukugqwala.
Uma ngabe i-oda lisho ukuthi amashubhu athunyelwe ngaphandleamafutha avimbela ukugqwala, ifilimu yamafutha okungenzeka ukuthi akhiqizwe iyohlala phezulu.
Ingakwazi ukuvimbela ngokuphumelelayo ubuso bepayipi ekuphenduleni ngomswakama nomoya-mpilo emoyeni, ngaleyo ndlela igweme ukugqwala nokugqwala.
Ngempela, nakuba i-lubricant eyisisekelo noma ifilimu kawoyela elula inganikeza izinga elithile lokuvikelwa kwesikhashana, ezinhlelweni ezidinga izinga eliphezulu lokuvikela, ukwelashwa okufanele kokuvikela ukugqwala kufanele kukhethwe ngakunye.
Isibonelo, kumapayipi agqitshiwe, a3PE(i-polyethylene enezingqimba ezintathu) ingasetshenziselwa ukuhlinzeka ngokuvikelwa kokugqwala kwesikhathi eside;amapayipi amanzi, iI-FBE(i-fusion-bonded epoxy powder) i-coating ingasetshenziswa, ngenkathiothayelaUkwelashwa kungase kube inketho ephumelelayo ezindaweni lapho kudingeka ukuvikelwa ngokumelene nokugqwala kwe-zinc.
Ngalobu buchwepheshe bokuvikela ukugqwala okukhethekile, impilo yesevisi yepayipi inganwetshwa kakhulu futhi nokusebenza kwayo kugcinwe.
Ukunemba okuphezulu: Ukubekezelelana kobukhulu obuncane kunamanye amashubhu ashiselwe.
Ikhwalithi yobuso: Izindawo ezibushelelezi zilungele izinhlelo zokusebenza ezidinga ukubukeka kobuhle nokungapheleli okuncane kwendawo.
Amandla nokuqina: Inqubo yokudweba okubandayo ithuthukisa izakhiwo zemishini, iyenze ifaneleke izicelo zokucindezeleka okuphezulu.
Ukusebenziseka kalula: Isebenza kalula ngomshini ngenxa yesakhiwo sayo esincane kanye nezakhiwo ezingaguquki kuyo yonke into.
Imboni yezimoto: ukwakhiwa kwezingxenye ezibalulekile ezifana nama-drive shafts, amashubhu okuthwala, amakholomu esiteringi, namasistimu amisiwe.
Izingxenye ze-Aerospace: ukwakhiwa kwamahlahla kanye nezingxenye zesakhiwo ezingabalulekile zendiza.
Imishini yezimboni: Isetshenziswa kakhulu ekwenzeni ama-shafts, amagiya, njll., ngenxa yobulula bawo bomshini nokuqina.
Izimpahla zemidlalo: izingxenye zesakhiwo ezifana namafreyimu ebhayisikili asebenza kahle kanye nempahla yokufaneleka.
Umkhakha wezamandla: isetshenziswa kubakaki noma izingxenye ze-roller zamaphaneli elanga.
Singomunye wabaphambili abashiselwe ipayipi lensimbi elishiselwe kanye nabakhiqizi nabahlinzeki bepayipi lensimbi engenamthungo abavela eChina, abanohlu olubanzi lwamapayipi ensimbi ekhwalithi ephezulu esitokweni, sizimisele ukukunikeza uhla olugcwele lwezixazululo zamapayipi ensimbi.
Ukuze uthole imininingwane eyengeziwe yomkhiqizo, sicela ukhululeke ukuxhumana nathi, sibheke phambili ekusizeni ukuthi uthole izinketho ezingcono kakhulu zamapayipi ensimbi ngezidingo zakho!
