Izindlela zokushisela ezivame kakhulu ezisetshenziswa ekwakhiweni kwamapayipi amakhulu athwala uketshezi olufana negesi yemvelo noma uwoyela zifaka phakathi ukushisela i-arc engaphansi komhlaba enamacala amabili (i-DSAW) kanye nokushisela i-arc engaphansi komhlaba ende (i-LSAW).
ukushintshwa okujikelezayo
Ipayipi Lensimbi le-DSAW:
Ukushisela Okude
Ukushisela Okude
I-LSAW ingenye yezinhlobo ze-DSAW.
I-DSAW isifinyezo se-"double-sided arc welding," igama eligcizelela ukusetshenziswa kwale ndlela.
I-LSAW imele i-"Longitudinal Submerged Arc Welding," indlela ebonakala ngama-weld adlula ubude bepayipi.
Kubalulekile ukuqaphela ukuthi i-DSAW ihlanganisa kokubili izinhlobo zamapayipi i-SSAW (Spiral Submerged Arc Welding) kanye nezinhlobo ze-LSAW.
Ukuhlola ukufana nomehluko phakathi kwe-DASW ne-LSAW empeleni kuwukuqhathanisa phakathi kwe-SSAW ne-LSAW.
Ukufana
Ubuchwepheshe Bokushisela
Bobabili i-DSAW kanye ne-LSAW basebenzisa inqubo yokushisela i-arc engaphansi kwezinhlangothi ezimbili (i-SAW), lapho ukushisela kwenziwa ngesikhathi esisodwa kuzo zombili izinhlangothi zensimbi ukuze kuthuthukiswe ikhwalithi kanye nokungena kwe-weld.
Izicelo
Kusetshenziswa kabanzi ezimweni lapho kudingeka khona amapayipi ensimbi anamandla aphezulu nobubanzi obukhulu, njengepayipi likawoyela negesi.
Ukubukeka Komthungo Wokushisela
Kukhona umthungo wokushisela obonakala kakhulu ngaphakathi nangaphandle kwepayipi lensimbi.
Umehluko
Uhlobo lokushisela
I-DSAW: Ingaqondile (ifakwe ngocingo olugoqekile ubude bepayipi) noma i-helical (ifakwe ngocingo olugoqekile ngendlela ejikelezayo emzimbeni wepayipi), kuye ngokusetshenziswa kanye nemininingwane yepayipi.
I-LSAW: Umthungo wokushisela ungaba ngowobude obude kuphela, lapho ipuleti lensimbi lifakwa khona ngomshini epayipini bese lishintshwa ngobude balo obude.
Gxila ekusetshenzisweni kwamapayipi ensimbi
I-DSAW: Njengoba i-DSAW ingaba iqondile noma i-spiral, ifaneleka kakhulu ezingcindezini eziningi ezahlukene kanye nobubanzi, ikakhulukazi uma kudingeka amapayipi amade kakhulu i-spiral i-DSAW ifaneleka kakhulu.
I-LSAW: Amapayipi ensimbi e-LSAW afaneleka kakhulu kwingqalasizinda yasemadolobheni kanye nezicelo zokucindezela okuphezulu njengokuthuthwa kwamanzi negesi.
Ukusebenza Kwepayipi
I-DSAW: Ipayipi elihlanganisiwe eliyi-Spiral alinawo amandla afanayo ne-LSAW ngokubekezelela ukucindezeleka.
I-LSAW: Ngenxa yenqubo yayo yokukhiqiza ipuleti lensimbi esebenzisa i-JCOE nezinye izinqubo zokubumba, udonga lwepayipi lensimbi lwe-LSAW lungamelana nezakhiwo ezifanayo zemishini.
Izindleko Nokusebenza Kahle Kokukhiqiza
I-DSAW: Uma ipayipi le-DSAW lihlanganiswe nge-spiral, ngokuvamile lishibhile futhi lishesha ukulikhiqiza futhi lifanelekela amapayipi akude.
I-LSAW: Ukushisela umthungo oqondile, yize kunikeza ikhwalithi ephezulu, kubiza kakhulu futhi kuhamba kancane ukukukhiqiza futhi kufanelekile ezinhlotsheni ezinezidingo zekhwalithi eziqinile.
Ukukhetha i-DSAW noma i-LSAW kuncike ezidingweni ezithile zephrojekthi, okuhlanganisa isabelomali, izingcindezi ipayipi elizidingayo ukuze lizibekezelele, kanye nobunzima bokukhiqiza nokufaka. Ukuqonda lokhu kufana okubalulekile kanye nomehluko kungasiza ekwenzeni isinqumo esifanele kakhulu sesicelo esithile sobunjiniyela.
