Manje amapayipi ensimbi akhona yonke indawo ekuphileni kwethu, kodwa indlela yokukhetha amapayipi ensimbi afanele ukuze sisetshenziswe?Amapayipi ensimbi asetshenziswa kakhulu futhi anezinhlobo eziningi.Amapayipi ensimbi angahlukaniswa abe izigaba ezimbili ngokwezindlela zokukhiqiza:amapayipi ensimbi angenamthungofuthiamapayipi ensimbi ashiselwe.Amapayipi ensimbi ashiselwe abizwa ngokuthi amapayipi ashiselwe ngamafuphi.Ngokwendlela yokukhiqiza, amapayipi ensimbi angenamthungo angahlukaniswa abe:amapayipi ensimbi angenamthungo ashisayo agingqiwe, amapayipi ensimbi angenamthungo adonswa abandayo, amapayipi ensimbi angenamthungo agoqeke abandayo, amapayipi anwetshiwe ashisayo, amapayipi asontekile abandayo, namapayipi anwetshiwe.Amapayipi ensimbi angenamthungozenziwe ngezinga eliphezuluinsimbi ye-carbon or insimbi ye-alloy, futhi ihlukaniswe yaba i-hot-rolled and cold-rolled (drawn).
Amapayipi ensimbi ashiselwe ahlukaniswe abe amapayipi ashiselwe esithandweni, amapayipi kagesi welding (resistance welding) kanye namapayipi a-arc ashiselwe ngokuzenzakalelayo ngenxa yezinqubo zawo zokushisela ezihlukene.Ahlukaniswe abe amapayipi ashiselwe ngomthungo oqondile kanye namapayipi ashiselwe okuvunguza ngenxa yezinhlobo zawo ezihlukene zokushisela.Ipayipi elihlanganisiwe elimise okwesipesheli (eliyisikwele, eliyisicaba, njll.) elishiselwe.Amapayipi ensimbi ashiselwe enziwe ngamapuleti ensimbi agoqiwe anezinqe noma ama-spiral seams.Ngokuphathelene nezindlela zokukhiqiza, aphinde ahlukaniswe abe amapayipi ensimbi ashiselwe okuthutha uketshezi olunomfutho ophansi, amapayipi ensimbi ashiselwe uthungo oluyi-spiral, amapayipi ensimbi aboshwe ngokuqondile, namapayipi ashiselwe kagesi.Amapayipi ensimbi angenamthungo angasetshenziswa kumapayipi omoya owuketshezi namapayipi egesi ezimbonini ezahlukahlukene.Amapayipi ashiselwe angasetshenziselwa amapayipi amanzi, amapayipi egesi, amapayipi okushisa, amapayipi kagesi, njll.
Kunezinhlobonhlobo eziningi zamapayipi ensimbi, lapho ukhetha, cabanga ngemvelo yepayipi ehlanganisiwe noma engenamthungo, ngakho ake sibheke.Umehluko phakathi kwepayipi elingenamthungo nepayipi elishiselwe
Ukukhiqiza: Ipayipi alinamthungo uma ligoqwa lisuka eshidini lensimbi libe sesimweni esingenamthungo.Lokhu kusho ukuthi azikho izikhala noma imithungo emapayipini.Kulula ukunakekela kunamapayipi ashiselwe njengoba kungekho ukuvuza noma ukugqwala emajoyintini.
Amapayipi ashiselwe ahlanganisa izakhi eziningi ezishiselwe ndawonye ukuze zakhe inhlanganisela.Ayaguquguquka kakhulu kunamapayipi angenamthungo ngenxa yokuthi amachopho awo awashiceleli, kodwa ayakwazi ukuvuza nokugqwala uma imithungo ingavalwanga kahle.
Izici: Ngokukhipha ipayipi usebenzisa i-die, ipayipi izoba yisimo esinwetshiwe esingenazikhala noma imithungo.Ngakho-ke, amapayipi ashiselwe ane-seams anamandla kunamapayipi akhishwe.
Ukushisela kuhilela ukusetshenziswa kwezinto zokushisa nezinto zokugcwalisa ukuze kuhlanganiswe izingcezu ezimbili zensimbi.Ngenxa yale nqubo yokugqwala, insimbi ingase ibe brittle noma ibe buthakathaka ngokuhamba kwesikhathi.
Amandla: Amandla epayipi elingenamthungo ngokuvamile athuthukiswa izindonga zawo eziwugqinsi.Ingcindezi yokusebenza yamapayipi ashiselwe ingaphansi ngo-20% kunaleyo yamapayipi angenamthungo futhi kufanele ihlolwe kahle ngaphambi kokusetshenziswa ukuze kuqinisekiswe ukuthi ngeke kube khona ukwehluleka.Nokho, amapayipi angenamthungo ahlala emafishane ngobude kunamapayipi ashiselwe ngoba amapayipi angenamthungo anzima kakhulu ukuwenza.Lawa mapayipi ngokuvamile asindayo kunamapayipi ashiselwe.Izindonga zamapayipi angenamthungo azifani ngaso sonke isikhathi njengoba zinokubekezelela okuqinile nokuqina okungaguquki.
Isicelo: Amapayipi ensimbi namapayipi ensimbi angenamthungo anezinzuzo eziningi kanye nezinzuzo.Amapayipi ensimbi angenasici anezakhiwo eziyingqayizivele ezifana nokusabalalisa isisindo esifanayo, izinga lokushisa eliphezulu nokumelana nokucindezela.La maphrojekthi angasetshenziswa ezimbonini ezehlukene njengezizinda zezimboni, izinhlelo ezisebenza ngamanzi, izizinda eziphehla amandla enuzi, izindawo zokuhlanza amanzi, izinto zokuxilonga, amapayipi kawoyela namandla, nokunye.
Ngokwentengo, ipayipi elishiselwe lithengeka kakhulu futhi lingakhiqizwa ngobukhulu obuhlukahlukene namafomu.Ziningi izimboni ezihlomulile, okubalwa kuzo ezokwakha, ezezindiza, ezokukhiqiza ukudla neziphuzo, ezokukhiqiza izimoto nezobunjiniyela.
Ngokuvamile, amapayipi angenamthungo noma ashiselwe kufanele akhethwe ngokuya ngezidingo zohlelo lokusebenza.Isibonelo, amapayipi angenamthungo kuhle uma ufuna ukuguquguquka nokulungisa kalula ngamavolumu aphezulu.Amapayipi ashiselwe alungele labo abadinga ukuphatha umthamo omkhulu woketshezi ngaphansi kwengcindezi ephezulu.
