Ipayipi lensimbi elishiselwe, elaziwa nangokuthi ipayipi elishiselwe, ipayipi lensimbi elenziwe ngepuleti lensimbi noma ngomugqa wensimbi ngemuva kokucwiliswa nokushiselwa.Ipayipi lensimbi elishiselwe linenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izinhlobo eziningi kanye nokucaciswa, kanye nemishini encane, kodwa amandla ayo ajwayelekile aphansi kunamapayipi ensimbi angenamthungo.Kusukela ngawo-1930, ngokuthuthuka okusheshayo kokukhiqizwa kwensimbi esezingeni eliphakeme eqhubekayo kanye nokuthuthuka kobuchwepheshe bokushisela nokuhlola, ikhwalithi yama-welds ibilokhu ithuthukiswa ngokuqhubekayo, izinhlobonhlobo kanye nokucaciswa kwamapayipi ensimbi ashiselwe kuye kwanda, nokuningi futhi. amasimu amaningi athathe indawo yensimbi engeyona insimbi.Ipayipi lensimbi yomthungo.Amapayipi ensimbi ashiselwe ahlukaniswe abe amapayipi othungelwano aqondile ahlanganisiwe kanye namapayipi ahlanganisiwe we-spiral seam ngokwendlela yokushisela.
Inqubo yokukhiqiza ipayipi ehlanganisiwe ye-seam ilula, ukusebenza kahle kokukhiqiza kuphezulu, izindleko ziphansi, futhi ukuthuthukiswa kuyashesha.Amandla epayipi elishiselwe ngomthungo ovunguzayo ngokuvamile aphakeme kunalawo epayipi elishiselwe ngomthungo oqondile, futhi ipayipi elishiselwe elinobubanzi obukhudlwana lingakhiqizwa nge-billet encane, kanti ipayipi elishiselwe elinamadayimitha amapayipi ahlukene nalo lingakhiqizwa nge i-billet yobubanzi obufanayo.Kodwa-ke, uma kuqhathaniswa nobude obufanayo bepayipi lomthungo oqondile, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.Ngakho-ke, amapayipi amaningi ashiselwe anama-diameter amancane asebenzisa i-seam welding eqondile, futhi iningi lamapayipi ahlanganisiwe anama-diameter amakhulu asebenzisa i-spiral welding.
1. Amapayipi ensimbi ashiselwe okuthutha uketshezi olunomfutho ophansi abizwa nangokuthi amapayipi ashiselwe ajwayelekile, aziwa ngokuthi amapayipi amnyama.Kuyipayipi lensimbi elishiselwe ukudlulisa uketshezi olujwayelekile lomfutho ophansi njengamanzi, igesi, umoya, uwoyela nesishifu sokushisisa nezinye izinjongo.Ukuqina kodonga lwepayipi lensimbi kuhlukaniswe ipayipi lensimbi elijwayelekile kanye nepayipi lensimbi elijiyile;ifomu lokuphela kwepayipi lihlukaniswe ngepayipi lensimbi elingenantambo (ipayipi elibushelelezi) kanye nepayipi lensimbi elinentambo.Ukucaciswa kwepayipi lensimbi kuvezwa ububanzi obujwayelekile (mm), okuwukulinganiselwa kobubanzi bangaphakathi.Kuyinto evamile ukuveza ngamasentimitha, njenge-11/2 njalonjalo.Ngaphezu kokusetshenziswa ngokuqondile ukuthutha uketshezi, amapayipi ensimbi ashiselwe okuthutha uketshezi olunomfutho ophansi nawo asetshenziswa kabanzi njengamapayipi okuqala amapayipi ensimbi ashiselwe ukuthutha uketshezi olunomfutho ophansi.
2. Ipayipi lensimbi eliphekiwe elishiselwe ukuthutha uketshezi olunomfutho ophansi libizwa nangokuthi ipayipi lensimbi eliphehliwe kagesi, elivame ukubizwa ngokuthi ipayipi elimhlophe.Kuyipayipi lensimbi elidiphu elishisayo elishiselwe (isithando somlilo elishiselwe noma elishiselwe ngogesi) elisetshenziselwa ukuhambisa amanzi, igesi, uwoyela womoya, ukushisisa isitimu, amanzi afudumele kanye nolunye uketshezi oluvamile olunomfutho ophansi noma ezinye izinhloso.Ukuqina kodonga lwepayipi lensimbi kuhlukaniswe ipayipi elivamile lensimbi kanye nepayipi lensimbi eliqinile;ifomu lokuphela kwepayipi lihlukaniswe ngepayipi lensimbi elingenalutho elinezintambo kanye nepayipi lensimbi elinentambo.Ukucaciswa kwepayipi lensimbi kuvezwa ububanzi obujwayelekile (mm), okuwukulinganiselwa kobubanzi bangaphakathi.Kuyinto evamile ukuveza ngamasentimitha, njenge-11/2 njalonjalo.
3. I-ordinary carbon steel wire casing iyipayipi lensimbi elisetshenziselwa ukuvikela izintambo kumaphrojekthi wokufaka ugesi njengezakhiwo zezimboni nezabantu, ukufakwa kwemishini nemishini.
4. Umthungo oqondile wepayipi kagesi oshiselwe ipayipi iyipayipi yensimbi ene-weld seam ehambisana nokuqondisa kwe-longitudinal yepayipi yensimbi.Imvamisa ihlukaniswe ngamapayipi ensimbi kagesi ashiselwe kagesi, ipayipi elicijile elinezindonga ezincane, ipayipi likawoyela lokupholisa i-transformer njalonjalo.
5. Ipayipi lensimbi eli-Spiral seam elingaphansi kwe-arc elishiselwe ukuthuthwa koketshezi olucindezelwe yipayipi lensimbi elivunguzayo elisetshenziselwa ukuthutha uketshezi olucindezelwe, okuyikhoyili yensimbi egoqelwe eshisayo njengeshubhu elingenalutho, evamise ukwakhiwa ngokuzungeza okufudumele, futhi elishiselwe ngokuphindwe kabili- ukushisela i-arc emaceleni engaphansi.Ipayipi lensimbi linamandla okuthwala ingcindezi kanye nokusebenza okuhle kwe-welding.Ngemuva kokuhlolwa okuqinile okunhlobonhlobo kwesayensi nokuhlolwa, kuphephile futhi kuthembekile ukusetshenziswa.Ububanzi bepayipi lensimbi bukhulu, ukusebenza kahle kwezokuthutha kuphezulu, futhi ukutshalwa kwezimali ekubekweni kwamapayipi kungagcinwa.Isetshenziselwa ikakhulukazi amapayipi okuthutha uwoyela negesi yemvelo.
6. Ipayipi lensimbi elishiselwe i-Spiral seam high-frequency high-frequency weld for uketshezi olucindezelayo lokuthuthwa lenziwa ngekhoyili yensimbi egoqelwe eshisayo njengeshubhu elingenalutho, elivame ukwakhiwa ngokuzungeza okufudumele, futhi lishiselwe nge-high-frequency lap welding.Ipayipi lensimbi elishiselwe.Ipayipi lensimbi linomthamo oqinile wokuthwala ingcindezi kanye nepulasitiki enhle, elungele ukushisela nokucubungula.Ngemuva kokuhlolwa nokuhlolwa okunhlobonhlobo okuqinile nokwesayensi, kuphephile futhi kuthembekile ukusetshenziswa.Ipayipi lensimbi linobubanzi obukhulu nokusebenza kahle kwezokuthutha, futhi lingagcina ukutshalwa kwezimali ekubekeni amapayipi.Isetshenziselwa kakhulu ukubeka amapayipi okuthutha uwoyela, igesi yemvelo, njll.
7. Ngokuvamile, umthungo ovunguzayo ongaphansi kwamanzi we-arc oshiselwe ipayipi lokuthutha uketshezi olunomfutho omncane wenziwa ngekhoyili yensimbi egoqelwe ngokushisayo njengeshubhu elingenalutho, futhi ngokuvamile lakheka ngokuzungeza okufudumele.Yenziwe nge-arc enezinhlangothi ezimbili ezizenzakalelayo zokushisela i-arc noma i-welding ehlangothini olulodwa yamanzi, igesi nomoya Amapayipi ensimbi afakwe ngaphansi kwe-arc okuthuthwa koketshezi olunengcindezi ephansi okujwayelekile njengesitimu nesitimu.
8. Ipayipi lensimbi elishiselwe i-spiral seam high-frequency high-frequency weld for general low-pressure fluid transportation senziwa ngekhoyili yensimbi egoqelwe eshisayo njengeshubhu elingenalutho, elivame ukwakhiwa ngokuzungeza okufudumele, futhi lishiselwa nge-high-frequency lap welding.Isetshenziselwa ukuthutha okujwayelekile koketshezi olunomfutho ophansi..
9. Amapayipi ensimbi anama-spiral-welded ezinqwaba enziwe ngamakhoyili ensimbi agoqelwe ashisayo njengezikhala zamashubhu, ngokuvamile akhiwa ama-spiral afudumele, futhi enziwe nge-arc welding enezinhlangothi ezimbili ezingaphansi kwamanzi noma i-high-frequency welding.Zisetshenziselwa izinqwaba zesisekelo ezifana nezakhiwo zokwakha umphakathi, ama-wharf, namabhuloho.Sebenzisa amapayipi ensimbi.
