Insimbi ye-ASTM A513iyipayipi lensimbi yekhabhoni ne-alloy kanye nethubhu elenziwe ngensimbi egoqekile noma egoqekile ebandayo njengezinto zokusetshenziswa ngenqubo yokumelana nokushisela (i-ERW), esetshenziswa kabanzi kuzo zonke izinhlobo zezakhiwo zemishini.
Uhlobo 5ngaphakathi kwendinganiso ye-ASTM A513 kubhekiselwa ku-Kudwetshwe Phezu Kwe-Mandrel (DOM)ipayipi.
Ipayipi le-DOM likhiqizwa ngokwakha ipayipi elihlanganisiwe bese lidonswa ngokubandayo ngokusebenzisa amadayi kanye naphezu kwama-mandrel ukuze liqedele ukubekezelelana okuseduze kanye nokuphela kobuso obubushelelezi uma kuqhathaniswa nezinye izinhlobo zamapayipi ahlanganisiwe.
Izinga lokusebenza: ASTM A513
Izinto: Insimbi Egoqwe Ngokushisayo noma Egoqwe Ngokubandayo
Uhlobo:Uhlobo1 (1a noma 1b), Uhlobo 2, Uhlobo 3, Uhlobo 4, Uhlobo 5, Uhlobo 6.
Ibanga: MT 1010, MT 1015,1006, 1008, 1009 njll.
Ukwelashwa ngokushisa: NA, SRA, N.
Usayizi kanye nobukhulu bodonga
Isimo sengxenye engenalutho: Indilinga, isikwele, noma ezinye izimo
Ubude
Inani Eliphelele
Izinhlobo ze-ASTM A513 zihlukaniswa ngokusekelwe ezimweni noma izinqubo ezahlukene zepayipi lensimbi.
I-ASTM A513 round tube uhlobo 5 olujwayelekile yilezi:
1008, 1009, 1010, 1015, 1020, 1021, 1025, 1026, 1030, 1035, 1040, 1340, 1524, 4130, 4140.
Isiyingi
Isikwele noma unxande
Ezinye izimo
njengezimo ezihlelekile, ezinezinhlangothi eziyisithupha, ezinezinhlangothi ezine, eziyindilinga ngaphakathi kanye nezinezinhlangothi ezine noma ezinezinhlangothi ezine ngaphandle, ezinemicu ngaphakathi noma ngaphandle, ezingonxantathu, eziyindilinga eziyizikwele, kanye nezimo ze-D.
Insimbi Egoqwe Ngokushisayo Noma Egoqwe Ngokubandayo
Izinto zokusetshenziswa zokukhiqiza i-Hot-rolled Steel noma i-Cold-rolled Steel zingakhiqizwa nganoma iyiphi inqubo.
Insimbi Egoqwe Ngokushisayo: Enqubweni yokukhiqiza, insimbi egoqwe ngokushisa iqala ifudunyezwe emazingeni okushisa aphezulu, okuvumela insimbi ukuthi igoqwe isesimweni sepulasitiki, okwenza kube lula ukushintsha ukuma nosayizi wensimbi. Ekupheleni kwenqubo yokugoqwa ngokushisa, izinto ezisetshenziswayo zivame ukukalwa futhi ziguquguquke.
Insimbi Egoqwe Ngobandayo: Insimbi egoqekile ebandayo igoqeka kakhulu ngemva kokuba izinto sezipholile ukuze kufezwe usayizi nesimo esifiselekayo. Le nqubo ivame ukwenziwa ekushiseni kwegumbi futhi iphumela ensimbini enekhwalithi engcono ebusweni kanye nobukhulu obunembile.
Amapayipi kufanele enziwe yi-okushiselwe ngokumelana nogesi (ERW)inqubo.
Ipayipi le-ERW inqubo yokwakha i-weld ngokuhlanganisa izinto zensimbi zibe yi-cylinder bese usebenzisa ukumelana nokucindezela ubude bayo.
Insimbi kumele ivumelane nezidingo zokwakheka kwamakhemikhali ezichazwe kuThebula 1 noma kuThebula 2.

Qaphela 1: Lawa manani asekelwe emazingeni okushisa avamile okunciphisa ukucindezeleka komshini. Ngezicelo ezithile, izakhiwo zingalungiswa ngokuxoxisana phakathi komthengi nomkhiqizi.
Inothi 2: Ekuhlolweni kwe-longitudinal strip, ububanzi besigaba se-gauge kufanele bube ngokwe-A370 Annex A2, Steel Tubular Products, kanye nokuncishiswa kwamaphuzu angu-0.5% kusukela ekunwetshweni okuncane okuyisisekelo kwento ngayinye.1/32ekunciphiseni [0.8 mm] kobukhulu bodonga ngaphansi5/16kuzovunyelwa ubukhulu bodonga obungu-[7.9 mm].
1% wawo wonke amapayipi endaweni ngayinye futhi angabi ngaphansi kwamapayipi ama-5.
Amashubhu ayindilinga namashubhu akha ezinye izimo uma eyindilinga ayasebenza.
Zonke izipayipi zizohlolwa nge-hydrostatic.
Gcina ingcindezi encane yokuhlolwa kwamanzi okungenani imizuzwana emi-5.
Ingcindezi ibalwa kanje:
P=2St/D
P= ingcindezi yokuhlola ye-hydrostatic encane, i-psi noma i-MPa,
S= ukucindezeleka kwefayibha okuvumelekile okungu-14,000 psi noma i-96.5 MPa,
t= ubukhulu bodonga obucacisiwe, ngo. noma mm,
D= ububanzi obungaphandle obucacisiwe, ngaphakathi noma mm.
Inhloso yalolu vivinyo ukwenqaba amapayipi aqukethe amaphutha alimazayo.
Ithubhu ngalinye kufanele lihlolwe ngokuhlolwa kukagesi okungabhubhisi ngokuhambisana ne-Practice E213, Practice E273, Practice E309, noma i-Practice E570.

Maka ulwazi olulandelayo ngendlela efanele ngenduku noma inqwaba ngayinye.
igama lomkhiqizi noma uhlobo, usayizi ocacisiwe, uhlobo, inombolo ye-oda lomthengi, kanye nale nombolo yencazelo.
I-Barcoding iyamukeleka njengendlela yokuhlonza eyengeziwe.
Amapayipi kufanele ambozwe ngefilimu yamafutha ngaphambi kokuthunyelwa ukuze kuvinjelwe ukugqwala.
Uma i-oda lichaza ukuthi amapayipi kufanele athunyelwe ngaphandleuwoyela ovimbela ukugqwala, ifilimu yamafutha akhiqizwayo izohlala phezu kwamanzi.
Kungavimbela ngempumelelo ubuso bepayipi ukuthi bungahlangani nomswakama nomoya-mpilo emoyeni, ngaleyo ndlela kugwenywe ukugqwala nokugqwala.
Ngempela, nakuba i-lubricant eyisisekelo noma ifilimu yamafutha elula inganikeza izinga elithile lokuvikelwa kwesikhashana, ngezinhlelo zokusebenza ezidinga izinga eliphezulu lokuvikelwa, ukwelashwa okufanele kokuvikela ukugqwala kufanele kukhethwe ngokwesimo ngasinye.
Isibonelo, ngamapayipi agqitshwe,3PEungqimba lwe-polyethylene olunezingqimba ezintathu lungasetshenziswa ukuhlinzeka ngokuvikelwa kokugqwala kwesikhathi eside; kumapayipi amanzi,I-FBEi-coating (i-fusion-bonded epoxy powder) ingasetshenziswa, ngenkathii-galvanizedUkwelashwa kungaba yindlela ephumelelayo ezindaweni lapho kudingeka khona ukuvikelwa ekugqwaleni kwe-zinc.
Ngalobu buchwepheshe obukhethekile bokuvikela ukugqwala, impilo yesevisi yepayipi ingandiswa kakhulu futhi ukusebenza kwayo kugcinwe.
Ukunemba okuphezulu: Ukubekezelelana okuncane kakhulu kunezinye izimbobo ezihlanganisiwe.
Ikhwalithi ephezulu: Izindawo ezibushelelezi zilungele ukusetshenziswa ezidinga ukubukeka okuhle kanye nokungapheleli okuncane kobuso.
Amandla nokuqina: Inqubo yokudonsa okubandayo ithuthukisa izakhiwo zemishini, okwenza ifaneleke ukusetshenziswa okunengcindezi ephezulu.
Ukusebenziseka kalula: Kulula ukuyisebenzisa ngenxa yesakhiwo sayo esincane esifanayo kanye nezakhiwo ezihambisanayo kuyo yonke into.
Imboni yezimoto: yokwenziwa kwezingxenye ezibalulekile njengemishayo yokushayela, amashubhu okuthwala, amakholomu okuqondisa, kanye nezinhlelo zokumiswa.
Izingxenye zezindiza: yokwenziwa kwama-bushing kanye nezingxenye zesakhiwo ezingabalulekile zezindiza.
Imishini yezimboni: Isetshenziswa kabanzi ekwakhiweni kwemigodi, amagiya, njll., ngenxa yokuthi kulula ukuyilungisa nokuqina kwayo.
Izimpahla zemidlalo: izingxenye zesakhiwo ezifana nohlaka lwebhayisikili olusebenza kahle kakhulu kanye nemishini yokufaneleka.
Umkhakha wamandla: esetshenziswa kuma-bracket noma izingxenye ze-roller zamaphaneli elanga.
Singomunye wabakhiqizi nabahlinzeki bepayipi lensimbi yekhabhoni elihlanganisiwe abahamba phambili kanye namapayipi ensimbi angenamthungo abavela eShayina, sinezinhlobonhlobo zamapayipi ensimbi asezingeni eliphezulu esitokweni, sizibophezele ekukunikezeni uhla oluphelele lwezixazululo zamapayipi ensimbi.
Ukuze uthole imininingwane eyengeziwe yomkhiqizo, sicela ukhululeke ukuxhumana nathi, silangazelela ukukusiza ukuthola izinketho ezinhle kakhulu zamapayipi ensimbi ezifanela izidingo zakho!
