Ukuqhathaniswa kwezinqubo zokukhiqiza zepayipi le-lsaw kanye nepayipi le-dsaw

I-Longitudinal Submerge-arc Amapayipi ashiselwe maduzane we-LSAW ipayipi iwuhlobo lwepayipi lensimbi elinomthungo wokushisela uhambisana ngobude nepayipi lensimbi, futhi izinto zokusetshenziswa kuyipuleti lensimbi, ngakho ukujiya kodonga lwamapayipi e-LSAW kungaba nzima kakhulu ngokwesibonelo u-50mm. , kuyilapho ububanzi bangaphandle bukhawulelwe ku-1420mm ukugqwesa.Ipayipi le-LSAW linenzuzo yenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi.

I-Double Submerged Arc Welded (DSAW) ipayipi iwuhlobo lwepayipi lensimbi elisontekile elishiselayo elenziwe ngekhoyili yensimbi njengempahla eluhlaza, evamise ukufudumeza i-extrusion futhi eshiselwe inqubo yokushisela engaphansi kwe-arc enezinhlangothi ezimbili.Ngakho ubude obubodwa bepayipi le-DSAW bungaba amamitha angu-40 kanti ubude obubodwa bepayipi le-LSAW bungamamitha angu-12 kuphela.Kodwa ubukhulu bodonga lwamapayipi e-DSAW bungaba ngu-25.4mm kuphela ngenxa yomkhawulo wamakhoyili ashisayo agoqwe.

Isici esivelele sepayipi lensimbi elivunguzayo ukuthi ububanzi obungaphandle bungenziwa bukhulu kakhulu, i-Cangzhou Spiral Steel Pipes Group Co.ltd ingakhiqiza amapayipi amakhulu amakhulu anobubanzi obungaphandle obungu-3500mm kakhulu.Phakathi nenqubo yokwenza, ikhoyili yensimbi ikhubazekile ngokulinganayo, ukucindezeleka okusalayo kuncane, futhi indawo engaphezulu ayiklwebheki.Ipayipi lensimbi elivunguzayo elicutshungulwayo linokuguquguquka okukhulu ebangeni lobukhulu bobubanzi nokuqina kodonga, ikakhulukazi ekukhiqizeni ipayipi elisezingeni eliphezulu, eliwugqinsi olukhulu, kanye nobubanzi obuncane ngepayipi elikhulu lokujiya odongeni, elinezinzuzo ezingenakuqhathaniswa kwezinye izinqubo.Ingahlangabezana nezidingo ezengeziwe zabasebenzisi ekucacisweni kwepayipi lensimbi elivunguzayo.Inqubo yokushisela ye-arc enezinhlangothi ezimbili ethuthukisiwe ingakwazi ukubona ukushisela endaweni engcono kakhulu, okungelula ukuba namaphutha njengokungahambi kahle, ukuphambuka kokushisela kanye nokungena okungaphelele, futhi kulula ukulawula ikhwalithi yokushisela.Kodwa-ke, uma kuqhathaniswa nepayipi lomthungo eliqondile elinobude obufanayo, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.
