Izindlela zokushisela ezivame kakhulu ezisetshenziswa ekwenziweni kwamapayipi anobubanzi obukhulu athwala uketshezi olufana negesi yemvelo noma uwoyela zifaka ukushisela kwe-arc engaphansi kwezinhlangothi ezimbili (i-DSAW) kanye ne-longitudinal submerged arc welding (LSAW).
i-spiral weld
Ipayipi Lensimbi le-DSAW:
I-Longitudinal Welding
I-Longitudinal Welding
I-LSAW ingenye yezinhlobo ze-DSAW.
I-DSAW isifinyezo se-"double-sided submerged arc welding," igama eligcizelela ukusetshenziswa kwale ndlela.
I-LSAW imele "Longitudinal Submerged Arc Welding," indlela ebonakala ngokushisela anwebeka ngobude bepayipi.
Kubalulekile ukuqaphela ukuthi i-DSAW ihlanganisa kokubili i-SSAW (Spiral Submerged Arc Welding) kanye nezinhlobo zamapayipi we-LSAW.
Ukuhlola ukufana nomehluko phakathi kwe-DASW ne-LSAW empeleni ukuqhathanisa phakathi kwe-SSAW ne-LSAW.
Ukufana
Welding Technology
Kokubili i-DSAW ne-LSAW zisebenzisa indlela yokushisela i-arc engaphansi kwezinhlangothi ezimbili (i-SAW), lapho ukushisela kwenziwa kanyekanye ezinhlangothini zombili zensimbi ukuze kuthuthukiswe ikhwalithi nokungena kwe-weld.
Izinhlelo zokusebenza
Isetshenziswa kakhulu ezimeni lapho amandla aphezulu kanye namapayipi ensimbi anobubanzi obukhulu adingeka, njengamapayipi kawoyela negesi.
Ukubukeka kwe-Weld Seam
Kukhona i-weld seam evelele kakhulu ngaphakathi nangaphandle kwepayipi lensimbi.
Umehluko
Uhlobo lwe-weld
I-DSAW: Ingaba iqonde (ishiselelwe ngobude bepayipi) noma i-helical (i-weld esongwe ngendlela ye-helical emzimbeni wepayipi), kuye ngokusetshenziswa kanye nezici zepayipi.
I-LSAW: Umthungo wokushisela ungaba yi-longitudinal kuphela, lapho ipuleti lensimbi lishintshwa libe yishubhu bese lishiselwa ngobude balo longitudinal.
Gxila ekusetshenzisweni kwamapayipi ensimbi
I-DSAW: Njengoba i-DSAW ingaba iqonde noma ithandele, ifaneleka kakhulu ezinhlobonhlobo zezingcindezi namadayamitha ahlukene, ikakhulukazi uma kudingeka amapayipi amade kakhulu i-spiral DSAW ifaneleka kakhulu.
I-LSAW: Amapayipi ensimbi e-LSAW afaneleka ngokukhethekile ingqalasizinda yasemadolobheni kanye nezicelo zokucindezela okuphezulu okufana nokuthuthwa kwamanzi negesi.
Ukusebenza Kwepayipi
I-DSAW: Ipayipi elishiselwe i-Spiral alinakho ukusebenza okufanayo njenge-LSAW mayelana nokubekezelela ingcindezi.
I-LSAW: Ngenxa yenqubo yayo yokukhiqiza ipuleti lensimbi lisebenzisa i-JCOE nezinye izinqubo zokubumba, udonga lwamapayipi ensimbi ye-LSAW lungamelana nezakhiwo ezifanayo zemishini.
Izindleko Nokukhiqiza Ngempumelelo
I-DSAW: Uma ipayipi le-DSAW lishiselwe ngokugobile ngokuvamile lishibhile futhi liyashesha ukulikhiqiza futhi lilungele amapayipi ahamba amabanga amade.
I-LSAW: I-Straight seam welding, ngenkathi ihlinzeka ngekhwalithi ephezulu, ibiza kakhulu futhi ihamba kancane ukuyikhiqiza futhi ifanele izinhlelo zokusebenza ezinezidingo zekhwalithi eziqinile.
Ukukhethwa kwe-DSAW noma i-LSAW kuncike ezidingweni ezithile zephrojekthi, okuhlanganisa isabelomali, izingcindezi ipayipi elidinga ukumelana nayo, kanye nobunkimbinkimbi bokukhiqiza nokufaka.Ukuqonda lokhu kufana nokwehluka okubalulekile kungasiza ukwenza isinqumo esifanele kakhulu sohlelo lokusebenza oluthile lobunjiniyela.
