Izindlela zokwenza ipayipi lensimbi ye-arc engaphansi kwamanzi zifaka ukwakheka kwe-twist eqhubekayo (HME), indlela yokwenza i-roll (CFE), indlela yokwenza i-Uing Oing Expanding (UOE), indlela yokwenza i-roll egoba (RBE), indlela yokwenza i-Jing Cing Oing Yokwandisa (JCOE), njll. Nokho, izindlela ezintathu zokwakha, i-UOE, i-RBE, ne-JCOE, zisetshenziswa kabanzi.

1. Indlela yokwenza i-UOE: Inqubo yokwenza iyunithi yepayipi lensimbi ye-UOE ihlukaniswe ngezinyathelo ezintathu ukuze iqedwe, okungukuthi ukugoba kwangaphambili, ukwakhiwa kokunyathelisa okumise okuka-U, kanye nokwakhiwa komshini wokunyathelisa okumise okwe-O, okulandelwa ukunwetshwa okubandayo kwalo lonke ipayipi ukuze kuqedwe ipayipi. ukwenza inqubo Ukucindezeleka okubangelwayo. Iyunithi yokwakha inemishini emikhulu kanye nezindleko eziphezulu. Isethi ngayinye yemishini yokwakha idinga ukuhlonyiswa ngama-welders amaningi angaphakathi nangaphandle, asebenza kahle kakhulu ekukhiqizeni. Ngenxa yephrofayili, ngemishini eminingi yokwakha, ipayipi lensimbi lobubanzi obubodwa lidinga isethi yesikhunta esithile sokwakha, futhi lezi zibunjwa zidinga ukushintshwa lapho kushintsha imininingwane yomkhiqizo. Ukucindezeleka kwangaphakathi kwepayipi elihlanganisiwe elibunjiwe likhulu ngokuqhathaniswa, futhi ngokuvamile lifakwe umshini okhulayo. Iyunithi ye-UOE inobuchwepheshe obuvuthiwe, izinga eliphezulu lokuzenzakalela, nemikhiqizo enokwethenjelwa, kodwa iyunithi inotshalomali olukhulu kumishini, elungele ukukhiqizwa kwemikhiqizo yevolumu enkulu.

2. Indlela yokwenza i-RBE: Izigaba zokwakheka kwe-RBE ziyagoqa, ziyagoba, futhi zinwetshwe ububanzi. Inqubo yokukhiqiza isivuthiwe. Esikhathini esidlule, i-RB yayisetshenziselwa ikakhulukazi ukukhiqiza imikhumbi yokucindezela, insimbi yesakhiwo, kanye namapayipi okuhambisa amanzi kanye nokukhipha amanzi anobubanzi obukhulu bangaphandle nobude obufushane. Ngenxa yokuthi amabhizinisi ajwayelekile awakwazi ukubekezelela ukutshalwa kwezimali okukhulu kweyunithi yokwenza amapayipi e-UOE, iyunithi yokwenza amapayipi e-RBE eyakhiwe ngokusekelwe ku-RB inezici zokutshalwa kwezimali okuncane, inqwaba emaphakathi, ukucaciswa komkhiqizo okulula, njll., ngakho ithuthuke ngokushesha. Ipayipi elishiselwe elikhiqizwe yile nqubo yokwakha liseduze nepayipi lensimbi le-UOE ngokuphathelene nokusebenza, ngakho lingangena esikhundleni sepayipi elishiselwe i-UOE ezimweni eziningi. Iyunithi yokwenza amapayipi e-RBE isebenzisa ukugoqa okunama-roll amathathu ukuze kuzuzwe ukwakhiwa kwamapayipi ensimbi. Inqubo yokwenza amapayipi iwukuthi umshini wokwenza ama-roll amathathu ugoqa ipuleti lensimbi libe yipayipi lensimbi eline-caliber, bese usebenzisa i-forming roll ukugoba unqenqema lwepayipi lensimbi. , Bese ugoba unqenqema ngomqulu owakhayo noma i-backbend. Ngenxa yokuthi iwukwakheka kwamaroli amathathu okuqhubekayo okugoba, ukusatshalaliswa kwengcindezi okukhiqizwa phakathi nenqubo yokwenza ipayipi lensimbi kufana ngokuqhathaniswa. Kodwa-ke, lapho ushintsha ukucaciswa komkhiqizo, kuyadingeka ukushintsha umqulu oyinhloko futhi ulungise umqulu ophansi ngendlela efanele. Iqoqo lama-core rolls emishini yokwakha lingacabangela imikhiqizo yokucaciswa okuningana. Okubi ukuthi isikali sokukhiqiza sincane, futhi ukushuba kodonga nobubanzi bepayipi lensimbi kuvinjelwe kakhulu ngenxa yethonya lamandla nokuqina kwe-roller eyinhloko.

3. Indlela yokwenza i-JCOE: Ukwakheka kwe-JCOE kunezigaba ezintathu, okungukuthi, ipuleti lensimbi licindezelwa kuqala libe umumo ongu-J, bese licindezelwa libe wumumo ongu-C kanye no-O ngokushintshana. U-E umele ukunwetshwa kobubanzi. I-JCOE yokwakha iyunithi yokwenza amapayipi ithuthukiswa ngokusekelwe kunqubo yokwenza i-UOE. Ifunda kumgomo wokusebenza we-U-shape futhi ikhiphe futhi isebenzise inqubo yokwenza i-UOE, enciphisa kakhulu ithoni yomshini wokwenza futhi ilondoloze ukutshalwa kwezimali kwemishini. Ipayipi lensimbi elikhiqizwayo liyafana nepayipi elishiselwe i-UOE, kodwa okukhiphayo kungaphansi kweyunithi yepayipi elishiselwe i-UOE. Le nqubo kulula ukubona ukulawula okuzenzakalelayo kunqubo yokwenza, futhi umumo womkhiqizo ungcono. Imishini yokwakha i-JCOE ingahlukaniswa cishe ibe yizinhlobo ezimbili, enye iwukugoba ukwakha, enye iwukwenza ukucindezela. Ukwakheka kokugoba kusetshenziswa kakhulu ekwenzeni amapuleti awugqinsi naphakathi nendawo, anezinyathelo ezincane kanye nokuphumayo okuphansi. Inqubo yokwakha iwukugingqa imiphetho emibili yepuleti lensimbi ibe yi-arc emshinini ogobayo ngokuya ngerediyasi yokugoba yepayipi elishiselwe, bese usebenzisa umshini wokwakha ukucindezela uhhafu wepuleti lensimbi libe yisimo esingu-C ngokusebenzisa eziningi. izinyathelo, bese uqala ukusuka kolunye uhlangothi lwepuleti lensimbi Ukucindezela, ngemva kokunyathela kaningi, olunye uhlangothi lwensimbi yensimbi luphinde lucindezelwe lube umumo ongu-C, ukuze lonke ipuleti lensimbi libe umumo ka-O ovulekile ukusuka phezulu.
