Ukwenziwa kwezinsuku zepayipi zensimbi kusukela ekuqaleni kweminyaka yama-1800. Ekuqaleni, ipayipi lenziwa ngesandla - ngokufudumeza, ukugoba, ukugoqa, kanye nokweqa imiphetho ndawonye. Inqubo yokuqala yokukhiqiza amapayipi ezenzakalelayo yethulwa ngo-1812 eNgilandi. Izinqubo zokukhiqiza zithuthuke njalo kusukela kuleso sikhathi. Amanye amasu athandwayo akhiqizwe amapayipi achazwe ngezansi.
I-Lap Welding
Ukusetshenziswa kwe-LOLDITING ukukhiqizwa kwepayipi kwenziwa ekuqaleni kwawo-1920. Yize indlela engasasebenzi, ipayipi elithile elenzelwe ukusebenzisa inqubo ye-welding ye-lallding isasebenza nanamuhla.
Enqubweni ye-LAF welding, insimbi yafuthelwa esithandweni somlilo bese ingena esimweni sesilinda. Imiphetho yepuleti yensimbi yabe seyishonile ". Isiphukubi sibandakanya ukumbozwa umphetho wangaphakathi wepuleti lensimbi, kanye nomphetho we-tapered okohlangothini oluphambene lwepuleti. Umthungo wabe eseshaywe esebenzisa ibhola le-welding, futhi ipayipi elivuthayo lidlulile phakathi kwama-roller aphoqa umthungo ndawonye ukudala isibopho.
Ama-welds akhiqizwa yi-lallding ye-lap awethembeki njengaleyo eyenziwe kusetshenziswa izindlela eziningi zesimanje. I-American Society of Mechanical Enjiniyela (ASME) ithuthukise i-equation yokubala ingcindezi yokusebenza evunyelwe yepayipi, ngokususelwa kuhlobo lwenqubo yokukhiqiza. Le equation ifaka phakathi kokuhluka ngokuthi "okuhlangene", okususelwa kuhlobo lwe-weld olusetshenziselwa ukudala umthungo wepayipi. Amapayipi angenamthungo ane-factor ehlanganyelwe yepayipi elingu-1,0 lelded anento ehlanganyelwe ka-0.6.
Ukumelana nogesi ipayipi elinqunyelwe
Ukumelana nogesi i-Welded (ERW) ipayipi kwakhiwa ngokudala ishidi lensimbi elibandayo libe yisakhiwo se-cylindrical. Okwamanje kudluliswa phakathi kwemiphetho emibili yensimbi ukushisa insimbi kuya endaweni lapho imiphetho iphoqelelwa khona ukuze kwakhiwe ibhondi ngaphandle kokusebenzisa impahla ye-welding filler. Kuqala le nqubo yokukhiqiza isebenzisa imvamisa ephansi ye-ac yamanje ukushisa imiphetho. Le nqubo ephansi yemvamisa yasetshenziswa kusukela ngonyaka we-1920 kwaze kwaba ngo-1970. Ngo-1970, inqubo yemvamisa ephansi yaxhaswa yinqubo ephezulu ye-ERW ekhiqize ikhwalithi ephezulu.
Ngokuhamba kwesikhathi, ama-welds we-erw frequency erw arw atholwe ukuthi athambekele ekukhetheni ukugqwala komshini, ukuqhekeka kwe-hook, kanye nokuhlanganiswa okunganele kwemikhumbi, ngakho-ke ukugcwala okuphansi kwe-suams, ngakho-ke ivampelicy eliphansi alisasetshenziselwa ukukhiqiza ipayipi. Inqubo yemvamisa ephezulu isasetshenziselwa ukwenza ipayipi lokusebenzisa ekwakhiweni okusha kwamapayipi.
Ipayipi likagesi we-welded welded
Ipayipi likagesi we-Welded Welded lakhiwe ekuqaleni ngo-1927. I-Flash Welding yenziwa ngokwakha ishidi lensimbi libe yisakhiwo se-cylindrical. Imiphetho yayifudunyezwa kuze kube yi-semi-inqumen, yabe isiphoqelelwa ndawonye kuze kube yilapho insimbi ebiwe yaphoqelelwa ukuphuma kokuhlanganiswa futhi yakha ubuhlalu. Njengamapayipi aphansi we-ERTW, ipayipi le-Flash Welded litholakala ekugcekeni nasekuqhekekeni kwe-hook, kodwa ngezinga elincane kunokwenziwa ipayipi le-ERW. Lolu hlobo lwepayipi luphinde lube sekwehluleka ukwehluleka ngenxa yamabala alukhuni kwinsimbi yeplanethi. Ngoba ipayipi eline-welded ye-Flash Welded likhiqizwa ngumenzi oyedwa, kukholelwa ukuthi la mabala anzima avela ngenxa yokuqedwa ngengozi kwensimbi ngesikhathi sokwenziwa komkhiqizi. I-Flash Welding ayisasetshenziselwa ukukhiqiza ipayipi.
Ipayipi elifakwe kabili le-arc welded (Dsaw)
Okufanayo nezinye izinqubo zokukhiqiza amapayipi, ukwenziwa kwepayipi elifakwe kabili le-arc efakwe i-arc kuhilela kuqala ukwakha amapuleti ensimbi kubunjwa be-cylindrical. Imiphetho yepuleti eligoqiwe yakhiwa ukuze kwakhiwe ama-VI-hlobo ama-grooves ezindlini ezingaphakathi nangaphandle endaweni yomthungo. Umthungo wepayipi ubese uhlakazwa ngokudlula okukodwa kwe-arc welder egumbini elingaphakathi nangaphandle (ngenxa yalokho kungeniswe kabili). I-arc ye-welding ifakwe ngaphansi kwe-flux.
Inzuzo yale nqubo ukuthi ama-welds angena e-100% yodonga lwepayipi futhi akhiqize isibopho esiqinile kakhulu sempahla yamapayipi.
Ipayipi elingenamthungo
Ipayipi elingenamthungo selikhiqizwe kusukela ngawo-1800. Ngenkathi inqubo ivele, izinto ezithile ziye zaqhubeka zinjalo. Ipayipi elingenamthungo lenziwa ngokubhoboza imali ekhokhwayo eshisayo eyindilinga nge-mandrel. Insimbi ethosiwe ingaphezu kokugoqwa futhi yelula ukufeza ubude obufunayo nobubanzi. Inzuzo eyinhloko yepayipi elingenamthungo ukuqedwa kwezinkinga ezihlobene nomthungo; Kodwa-ke, izindleko zokukhiqiza zinkulu.
Ipayipi lasekuqaleni lingenamthungo lalitholakala ekulimaleni okubangelwa ukungcola ngensimbi. Njengoba amasu we-Insimbi enza ngcono, lezi ziphutha zancishiswa, kepha azizange ziqedwe ngokuphelele. Ngenkathi kubonakala sengathi ipayipi elingenamthungo lizothandwa ukwakheka, ipayipi le-seam-welded, amandla okuthuthukisa izici ezifiselekayo kupayipi lilinganiselwe. Ngalesi sizathu, ipayipi elingenamthungo okwamanje liyatholakala kumabanga aphansi kanye nobukhulu bodonga kunepayipi eline-welded.
I-Jindalai Steel Iqembu likhethekile ekukhiqizeni i-ERP-Tech ERW (ukumelana nogesi i-Welded) kanye ne-SSAW (WILL COWNED ARCHWETED) PIPES). Inkampani yethu ithuthukile φ610 mm ephezulu kakhulu-imvamisa yomshini wokumelana we-selding we-selding, futhi φ30mm Spiral ARC Welded Machine. Futhi, ngaphandle kwamafektri e-ERW ne-SSAW, sinamanye amafektri amathathu ahambisana nokukhiqizwa kwe-LSAW ne-SML kulo lonke elaseChina.
Uma ukuthengwa kwamapayipi kusekusasa lakho eliseduze, cela isilinganiso. Sizohlinzeka ngokuthola okukuthola ngqo imikhiqizo oyidingayo ngokushesha. Thumela uphenyo lwakho futhi sizokujabulela ukukubona kahle.
Thina Jinganilai Steel Group singumkhiqizi, othumela ngaphandle, umnikazi wesitoko nomhlinzeki wohlobo lwe-acleative of steel. Sinekhasimende kusuka ku-Thane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, MyAnmar. Thumela uphenyo lwakho futhi sizokujabulela ukukubona kahle.
