Ukwakhiwa kwamapayipi ensimbi kwaqala ekuqaleni kwawo-1800. Ekuqaleni, ipayipi lakhiwe ngesandla - ngokufudumeza, ukugoba, ukugoqa, nokushaya imiphetho ndawonye. Inqubo yokuqala yokukhiqiza ipayipi ezenzakalelayo yethulwa ngo-1812 eNgilandi. Izinqubo zokukhiqiza ziye zathuthuka ngokuqhubekayo kusukela ngaleso sikhathi. Amanye amasu athandwayo okukhiqiza amapayipi achazwe ngezansi.
I-Lap Welding
Ukusetshenziswa kwe-lap welding ukwenza ipayipi kwaqalwa ekuqaleni kwawo-1920. Nakuba le ndlela ingasasetshenziswa, elinye ipayipi elakhiwe kusetshenziswa inqubo yokushisela emathangeni lisasetshenziswa nanamuhla.
Enqubweni yokushisela i-lap, insimbi yayishiswa esithandweni bese igoqwa ibe yisilinda. Imiphetho yepuleti lensimbi bese "ifakwe isikhafu". I-scarfing ihlanganisa ukumboza unqenqema lwangaphakathi lwepuleti lensimbi, kanye nomphetho ocijile wohlangothi oluphambene lwepuleti. Umthungo wabe usushiselwa kusetshenziswa ibhola lokushisela, futhi ipayipi elishisayo lalidluliselwa phakathi kwama-roller okwakuphoqa ukuthi umthungo uhlangane ukuze wakhe isibopho.
Ama-welds akhiqizwa yi-lap welding awathembekile njengalawo adalwe kusetshenziswa izindlela zesimanje. I-American Society of Mechanical Engineers (ASME) ithuthukise isibalo sokubala ukucindezela okuvumelekile kokusebenza kwepayipi, ngokusekelwe ohlotsheni lwenqubo yokukhiqiza. Lesi sibalo sihlanganisa okuguquguqukayo okwaziwa ngokuthi "i-joint factor", esekelwe ohlotsheni lwe-weld olusetshenziselwa ukudala umthungo wepayipi. Amapayipi angenamthungo anesici esihlangene sepayipi elishiselwe i-Lap elinesici esihlangene esingu-0.6.
Ipayipi Elishiselwe Ukumelana Nogesi
Ipayipi elishiselwe ukumelana nogesi (ERW) lakhiwa ngokubandayo-lakha ishidi lensimbi libe yisimo esiyicylindrical. Okwamanje idluliswa phakathi kwemiphetho emibili yensimbi ukushisa insimbi kuze kube iphuzu lapho imiphetho iphoqeleka ndawonye ukuze yakhe isibopho ngaphandle kokusetshenziswa kwempahla yokugcwalisa i-welding. Ekuqaleni le nqubo yokukhiqiza isebenzisa imvamisa ephansi ye-AC yamanje ukushisisa imiphetho. Le nqubo yefrikhwensi ephansi yasetshenziswa kusukela ngeminyaka yawo-1920 kwaze kwaba ngu-1970. Ngo-1970, inqubo yefrikhwensi ephansi yathathelwa indawo yinqubo ye-ERW ephakeme kakhulu eyakhiqiza ikhwalithi ephezulu yokushisela.
Ngokuhamba kwesikhathi, amashisela epayipi le-ERW elivama kancane atholakala esengozini yokugqwala komthungo, ukuqhekeka kwehhuku, kanye nokungahlangani okwanele kwemithungo, ngakho-ke i-ERW yefrikhwensi ephansi ayisasetshenziswa ukwenza ipayipi. Inqubo yefrikhwensi ephezulu isasetshenziswa ukwenza amapayipi azosetshenziswa ekwakhiweni kwamapayipi amasha.
Ipayipi Elishiselwe I-Flash Kagesi
Ipayipi likagesi elishiselwe nge-flash lakhiqizwa kusukela ngo-1927. Ukushisela i-flash kwafezwa ngokwenza ishidi lensimbi libe yisimo esiyicylindrical. Imiphetho yayishisiswe ize incibilike kancane, bese ihlanganiswa ndawonye kuze kube yilapho insimbi encibilikisiwe ikhishwa ehlangene futhi yakhe ubuhlalu. Njengepayipi le-ERW elivama kancane, imithungo yepayipi elishiselwe kalula iyakwazi ukugqwala nokuqhekeka kwehhuku, kodwa kancane kunepayipi le-ERW. Lolu hlobo lwepayipi luyakwazi nokuhluleka ngenxa yamabala aqinile ensimbi yepuleti. Ngenxa yokuthi iningi lamapayipi ashiselwe nge-flash akhiqizwa umkhiqizi oyedwa, kukholakala ukuthi lezi zindawo eziqinile zenzeka ngenxa yokucisha insimbi ngephutha ngesikhathi sokukhiqiza esetshenziswa yilowo mkhiqizi. I-Flash welding ayisasetshenziswa ukwenza ipayipi.
I-Double Submerged Arc Welded (DSAW) Pipe
Ngokufanayo nezinye izinqubo zokukhiqiza amapayipi, ukwakhiwa kwe-Double Submerged Arc Welded Pipe kuhilela ukwakhiwa kwamapuleti ensimbi abe yizimo eziyisilinda. Amaphethelo epuleti eligoqiwe akhiwa ukuze ama-grooves amise okwe-V akheke endaweni yangaphakathi nangaphandle endaweni yomthungo. Umthungo wepayipi ube usushiselwa ngephasi eyodwa ye-arc welder endaweni yangaphakathi nengaphandle (ngakho-ke icwiliswa kabili). I-arc ye-welding icwiliswa ngaphansi kwe-flux.
Inzuzo yale nqubo ukuthi ama-welds angena ku-100% odongeni lwamapayipi futhi akhiqize isibopho esinamandla kakhulu sempahla yepayipi.
Ipayipi Elingenamthungo
Ipayipi elingenamthungo lakhiwe kusukela ngeminyaka yawo-1800. Ngenkathi inqubo iguqukile, izakhi ezithile azishintshile. Ipayipi elingenamthungo likhiqizwa ngokubhoboza i-billet yensimbi eyindilinga eshisayo nge-mandrel. Insimbi enezimbobo ingaphezu kokugoqwa futhi yeluliwe ukuze kuzuzwe ubude nobubanzi obufunekayo. Inzuzo eyinhloko yepayipi elingenamthungo ukuqedwa kwamaphutha ahlobene nomthungo; nokho, izindleko zokukhiqiza zinkulu.
Ipayipi langaphambili elingenamthungo lalisengozini yokulimala okubangelwa ukungcola okusensimbi. Njengoba izindlela zokwenza insimbi zithuthuka, lezi zici zancipha, kodwa azikaqedwa ngokuphelele. Nakuba kubonakala sengathi ipayipi elingenamthungo lingakhethwa ukwakha, ipayipi elishiselwe ngomthungo, amandla okuthuthukisa izici ezifiselekayo kumapayipi anomkhawulo. Ngenxa yalesi sizathu, ipayipi elingenamthungo okwamanje litholakala emazingeni aphansi kanye nogqinsi lwezindonga kunepayipi elishiselwe.
I-Jindalai Steel Group ikhethekile ekukhiqizeni amapayipi obuchwepheshe be-ERW (Electric Resistance Welded) kanye ne-SSAW (Spiral Submerged Arc welded). Inkampani yethu isithuthukele phambili ngomshini wokushisela we-φ610 mm we-high-frequency straight straight seam welding, kanye nomshini oshiselwe i-arc ovunguzayo ongu-φ3048mm. Futhi, ngaphandle kwezimboni ze-ERW kanye ne-SSAW, sinezinye izimboni ezintathu ezihlotshaniswayo zokukhiqiza i-LSAW ne-SMLS kulo lonke elaseShayina.
