Incazelo Yomkhiqizo
Amapayipi ensimbi e-LSAW (Longitudinal Submerged Arc Welding) awuhlobo lwamapayipi ensimbi ashiselwe elibonakala ngenqubo yawo yokukhiqiza eyingqayizivele kanye nobubanzi bezinhlelo zokusebenza.Lawa mapayipi akhiqizwa ngokwakha ipuleti lensimbi libe yisimo esiyisilinda futhi alishisele ngobude kusetshenziswa amasu okushisela ama-arc angaphansi kwamanzi.Nakhu okufingqiwe kwamapayipi ensimbi e-LSAW:
Inqubo Yokukhiqiza:
● Ukulungiswa Kwepuleti: Amapuleti ensimbi ekhwalithi ephezulu akhethwa ngokusekelwe ezidingweni ezithile, okuqinisekisa izici zemishini ezifunwayo kanye nokwakheka kwamakhemikhali.
● Ukwakha: I-steel plate ibunjwa ibe yipayipi eliyisilinda ngezinqubo ezinjengokugoba, ukugoqa, noma ukucindezela (i-JCOE ne-UOE).Imiphetho igobile ngaphambili ukuze kube lula ukushisela.
● Ukushisela: I-arc welding engaphansi kwamanzi (SAW) isetshenziswa, lapho i-arc igcinwa ngaphansi kwesendlalelo se-flux.Lokhu kukhiqiza amashisela ekhwalithi ephezulu anamaphutha amancane kanye nokuhlanganisa okuhle kakhulu.
● Ukuhlolwa kwe-Ultrasonic: Ngemva kokushisela, ukuhlolwa kwe-ultrasonic kwenziwa ukuze kutholwe noma yikuphi ukukhubazeka kwangaphakathi noma kwangaphandle endaweni yokushisela.
● Ukunwetshwa: Ipayipi linganwetshwa ukuze kuzuzwe ububanzi obufunekayo nokuqina kodonga, kuthuthukise ukunemba kobukhulu.
● Ukuhlola Okokugcina: Ukuhlola okuphelele, okuhlanganisa ukuhlola okubonakalayo, ukuhlola ubukhulu, nokuhlolwa kwezakhiwo eziwumshini, kuqinisekisa ikhwalithi yepayipi.
Izinzuzo:
● Ukusebenza Kahle Kwezindleko: Amapayipi e-LSAW anikeza isixazululo esingabizi kakhulu samapayipi anobubanzi obukhulu kanye nezicelo zesakhiwo ngenxa yenqubo yawo yokukhiqiza ephumelelayo.
● Amandla Aphezulu: Indlela yokushisela i-longitudinal iphumela kumapayipi anezakhiwo eziqinile nezifanayo zemishini.
● Ukunemba Kobukhulu: Amapayipi e-LSAW abonisa ubukhulu obunembile, okuwenza afanelekele izinhlelo zokusebenza ezinokubekezelelwa okuqinile.
● Ikhwalithi yokushisela: I-arc welding engaphansi kwamanzi ikhiqiza ama-welds ekhwalithi ephezulu anokuhlanganiswa okuhle kakhulu kanye nokukhubazeka okuncane.
● Ukuhlukahluka: Amapayipi e-LSAW asetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa uwoyela negesi, ukwakhiwa, nokuphakelwa kwamanzi, ngenxa yokuvumelana nezimo nokuqina kwawo.
Kafushane, amapayipi ensimbi e-LSAW akhiqizwa kusetshenziswa inqubo enembile nephumelelayo, okuholela kumapayipi aguquguqukayo, angabizi kakhulu, futhi ahlala isikhathi eside afanele uhla olubanzi lwezicelo zezimboni.

Ukusetshenziswa & Isicelo
Amapayipi ensimbi e-LSAW (Longitudinal Submerged Arc Welding) athola izinhlelo zokusebenza ezihlukene kuzo zonke izimboni ngenxa yobuqotho besakhiwo nokuguquguquka.Ngezansi okunye ukusetshenziswa okubalulekile kanye nokusetshenziswa kwamapayipi ensimbi e-LSAW:
● Ukuthuthwa Kwamafutha Negesi: Amapayipi ensimbi e-LSAW asetshenziswa kakhulu embonini kawoyela negesi kumasistimu amapayipi.La mapayipi asetshenziselwa ukuthutha uwoyela ongahluziwe, igesi yemvelo, nolunye uketshezi noma amagesi.
● Ingqalasizinda yamanzi: Amapayipi e-LSAW asetshenziswa ezinhlelweni zengqalasizinda ehlobene namanzi, okuhlanganisa ukuphakelwa kwamanzi nezinhlelo zokudonsa amanzi.
● Ukucubungula Amakhemikhali: Amapayipi e-LSAW asebenza ezimbonini zamakhemikhali lapho eqashwe khona ukuze adlulise amakhemikhali, uketshezi, namagesi ngendlela evikelekile nephumelelayo.
● Ukwakhiwa Nengqalasizinda: La mapayipi asetshenziswa emisebenzini yokwakha ehlukahlukene, njengezisekelo zokwakha, amabhuloho nezinye izakhiwo.
● Ukufakwa kwe-Piling: Amapayipi e-LSAW asetshenziswa ekunqwabeleni izicelo ukuze anikeze ukusekelwa okuyisisekelo kumaphrojekthi wokwakha, okuhlanganisa isisekelo sezakhiwo nezakhiwo zasolwandle.
● Umkhakha Wamandla: Asetshenziselwa ukuthutha izinhlobo ezihlukahlukene zamandla, okuhlanganisa isitimu noketshezi olushisayo ezimbonini zokuphehla ugesi.
● Ukumbiwa kwezimayini: Amapayipi e-LSAW athola isicelo kumaphrojekthi wezimayini ukuze kudluliswe izinto zokwakha kanye nemisila.
● Izinqubo Zezimboni: Izimboni ezifana nokukhiqiza nokukhiqiza zisebenzisa amapayipi e-LSAW ezinqubweni ezehlukene zezimboni, okuhlanganisa ukudlulisa izinto zokusetshenziswa nemikhiqizo eqediwe.
● Ukuthuthukiswa Kwengqalasizinda: Lawa mapayipi abalulekile ekuthuthukiseni amaphrojekthi engqalasizinda afana nemigwaqo, imigwaqo emikhulu, nezinsiza ezingaphansi komhlaba.
● Ukusekelwa Kwesakhiwo: Amapayipi e-LSAW asetshenziselwa ukwakha izisekelo zesakhiwo, amakholomu, nemishayo kumaphrojekthi wokwakha nawonjiniyela.
● Ukwakhiwa kwemikhumbi: Embonini yokwakha imikhumbi, amapayipi e-LSAW asetshenziselwa ukwakha izingxenye ezihlukahlukene zemikhumbi, okuhlanganisa ama-hull kanye nezingxenye zesakhiwo.
● Imboni Yezimoto: Amapayipi e-LSAW angasetshenziswa ekwenzeni izingxenye zezimoto, okuhlanganisa nesistimu yokukhipha umoya.
Lezi zinhlelo zokusebenza zibonisa ukuguquguquka kwamapayipi ensimbi e-LSAW emikhakheni eyahlukene, ngenxa yokuqina kwawo, amandla, nokufaneleka kwezimo zemvelo ezihlukahlukene.
Ukupakisha Nokuthumela
Ukupakishwa nokuthunyelwa ngendlela efanele kwamapayipi ensimbi e-LSAW (Longitudinal Submerged Arc Welding) kubalulekile ukuze kuqinisekiswe ukuthutha kwawo okuphephile nokulethwa ezindaweni ezihlukahlukene.Nansi incazelo yezinqubo ezijwayelekile zokupakisha nezokuthumela zamapayipi ensimbi e-LSAW:
Ukupakisha:
● Ukuhlanganisa: Amapayipi e-LSAW avame ukunqwabelana ndawonye noma Ucezu Olulodwa lupakishwe kusetshenziswa amabhande ensimbi noma amabhande ukuze akhe amayunithi aphathekayo okuphatha nezokuthutha.
● Ukuvikela: Iziphetho zamapayipi zivikelwe ngamakepisi epulasitiki ukuze kuvinjelwe umonakalo ngesikhathi sokuthutha.Ukwengeza, amapayipi angambozwa ngezinto ezivikelayo ukuze avikeleke ezintweni ezithinta imvelo.
● I-Anti-Corrosion Coating: Uma amapayipi ane-anti-corrosion coating, ubuqotho bokwemboza buqinisekiswa ngesikhathi sokupakisha ukuvimbela ukulimala ngesikhathi sokuphatha nokuthutha.
● Ukumaka nokulebula: Inqwaba ngayinye ifakwe ilebula yolwazi olubalulekile njengosayizi wepayipi, izinga lempahla, inombolo yokushisa, nezinye izicaciso ukuze zikhonjwe kalula.
● Ukuvikela: Izinqwaba ziboshelwe ngokuvikelekile kuma-pallets noma kuma-skid ukuvimbela ukunyakaza ngesikhathi sokuthutha.
Ukuthumela:
● Izindlela Zokuthutha: Amapayipi ensimbi e-LSAW angathunyelwa kusetshenziswa izindlela zokuthutha ezihlukahlukene, kuhlanganise nomgwaqo, ujantshi, ulwandle, noma umoya, kuye ngendawo okuyiwa kuyo kanye nokuphuthuma.
● Ukufakwa Kweziqukathi: Amapayipi angathunyelwa ngeziqukathi ukuze avikeleke okwengeziwe, ikakhulukazi ngesikhathi sokuthutha phesheya kwezilwandle.Iziqukathi ziyalayishwa futhi zivikelekile ukuze kuvinjelwe ukugudluka ngesikhathi sokuthutha.
● Ozakwethu Bezinto Zokusebenza: Izinkampani zempahla ehloniphekile noma abathwali abanolwazi ekuphatheni amapayipi ensimbi bayabandakanyeka ukuze kuqinisekiswe ukulethwa okuphephile nokufika ngesikhathi.
● Imibhalo Yentela Yempahla Ethengiswayo: Imibhalo edingekayo yentela yempahla, okuhlanganisa nezikweletu zempahla, izitifiketi zendabuko, namanye amaphepha afanelekile, ayalungiselelwa futhi athunyelwe ukuze athunyelwe kwamanye amazwe.
● Umshwalense: Kuye ngevelu kanye nohlobo lwempahla, ukufakwa komshwalense kungase kuhlelwe ukuze kuvikelwe izehlakalo ezingalindelekile phakathi nokuhamba.
