Ukusetshenziswa kwamapayipi angaphansi kwe-arc welded (DSAW) kuya ngokuya kuduma embonini yanamuhla.Lawa mapayipi enziwa ngokwenza izingcwecwe zensimbi zibe yizimo eziyisilinda bese zishisela imithungo kusetshenziswa inqubo yokushisela i-arc engaphansi kwamanzi.Umphumela uba izinga eliphezulu, ipayipi eliqinile elinikeza izinzuzo eziningi ezihlukahlukene zezinhlelo zokusebenza zezimboni.
Enye yezinzuzo eziyinhloko zeIpayipi le-DSAWamandla ayo angavamile kanye nokuqina.Inqubo yokushisela i-arc engaphansi kwamanzi esetshenziselwa ukwenza la mapayipi iqinisekisa ukuthi ama-seams aqine kakhulu futhi mancane amathuba okuqhekeka noma ukuphuka ngaphansi kwengcindezi.Lokhu kwenza ipayipi le-DSAW lilungele izicelo ezidinga izinga eliphezulu lobuqotho besakhiwo, njengemboni kawoyela negesi, ukuthuthwa kwamanzi namaphrojekthi wokwakha.
Ngaphezu kwamandla, amapayipi ashiselwe i-arc angaphansi kwamanzi anikezela ngokunemba okuhle kakhulu kobukhulu.Inqubo yokushisela esetshenziselwa ukwenza lawa mapayipi iphumela ekugqileni kodonga olufanayo kanye nobubanzi obungaguquguquki, iqinisekisa ukufaneleka okunembile nokusebenza okuthembekile ezinhlelweni ezihlukahlukene.Leli zinga lokunemba kwe-dimensional libalulekile ezimbonini ezidinga ukubekezelelana okuqinile ukuze zigcine ubuqotho nokusebenza kwezinhlelo zamapayipi.
Ukwengeza, amashubhu e-DSAW afaneleka kahle ukuthi asetshenziswe ezindaweni zokucindezela okukhulu kanye nezinga lokushisa eliphezulu.Ukwakhiwa okuqinile kwala mapayipi kubavumela ukuba babhekane nezimo ezimbi kakhulu ngaphandle kokuphazamisa ubuqotho babo besakhiwo.Lokhu kubenza babe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezifana nokudluliswa kwe-steam, amasistimu we-boiler kanye nokucubungula kwamakhemikhali, lapho amapayipi kufanele akwazi ukumelana namazinga okushisa aphezulu kanye nezingcindezi ngaphandle kokwehluleka.
Enye inzuzo yepayipi le-DSAW ukusebenza kahle kwayo kwezindleko.Inqubo yokukhiqiza ephumelelayo esetshenziselwa ukukhiqiza la mapayipi ivumela umkhiqizo ukuletha izinga eliphezulu lokusebenza ngezindleko eziphansi kakhulu.Lokhu kwenza amapayipi e-DSAW abe yisixazululo esingabizi kakhulu sezinkampani ezifuna ukunciphisa izindleko ngaphandle kokudela ikhwalithi yesistimu yamapayipi noma ukwethembeka.
Ukwengeza, amashubhu e-DSAW ahlukahlukene kakhulu futhi angasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza.Kungakhathaliseki ukuthi asetshenziselwa ukuthutha amanzi, uwoyela, igesi yemvelo noma okunye uketshezi, amapayipi e-DSAW ahlinzeka ngezixazululo ezinokwethenjelwa, eziphumelelayo zezidingo ezihlukahlukene zezimboni.Ukuvumelana nezimo nokuqina kwazo kuzenza zilungele izimboni ezinezidingo ezihlukene zamapayipi.
Kafushane, ukusetshenziswa kwe-arc engaphansi kwamanzi kabiliipayipi elishiselwekuzinhlelo zokusebenza zezimboni kunikeza izinzuzo eziningi, okuhlanganisa amandla aphakeme nokuqina, ukunemba okuhle kakhulu kobukhulu, ukufaneleka kokucindezela okuphezulu nezimo zokushisa okuphezulu, ukuphumelela kwezindleko, kanye nokuhlukahluka.Lezi zinzuzo zenza amapayipi e-DSAW abe yinketho ekahle ezinkampanini ezifuna ukuqinisekisa ukwethembeka nokusebenza kwesikhathi eside kwezinhlelo zazo zamapayipi.Ngenxa yalokho, ipayipi le-DSAW seliyingxenye ebalulekile yengqalasizinda yezimboni zesimanje futhi ukusetshenziswa kwayo kabanzi kuyaqhubeka nokukhula njengoba imboni ibona inani elihlinzekayo.
