Ukwakha ipayipi, ikakhulukazi ipayipi legesi eligqitshwe ngaphansi komhlaba, ukukhetha izinto zesisekelo ezifanele kubaluleke kakhulu kunanoma yini enye. Muva nje, sithole imibuzo eminingi evela kumakhasimende mayelana nezinqwaba zamapayipi ensimbi, ikakhulukazi maqondana nokuhambisana kwemininingwane kanye nezimo. Namuhla, ake sixoxe ngalokhu.
Kungani sicabangela "isimo se-cylindrical" kanye "nosayizi" wezinqwaba zamapayipi ensimbi?
Empeleni isimiso silula impela. Indawo engaphansi komhlaba iyinkimbinkimbi, enezici ezifana nokucindezela komhlabathi, ukugqwala, kanye nokwehluka kwezinga lokushisa konke kuhlola imikhawulo yamapayipi. Kuleli qophelo,Izinqwaba Zepayipi Lensimbi Zomumo Wesilindaiba ukukhetha okuthembekile kakhulu. Isimo esiyindilinga sisabalalisa amandla ngokulinganayo, okwenza kube lula ukuthi ziwohloke ngesikhathi sokunqwabelana, futhi kulula nokubikezela ukuthi ukungqubuzana nenhlabathi kuzokwenzeka kanjani.
Sesisebenze neCangzhou Spiral Steel Pipe Group iminyaka eminingi. Umbono ojulile esinawo ukuthi ukuba nesimo esifanele akwanele; ubukhulu kumele buhambisane nezidingo zephrojekthi. Ukujula kokungcwaba kanye nomthwalo wamapayipi egesi yemvelo kuyahlukahluka, futhi okukhethiweUsayizi Wezinqwaba Zepayipi Lensimbi, kusukela kububanzi kuya ekujiyeni kodonga, kumele kube okuqondile ngaphandle kokuphambuka. Isibonelo, amanye amaphrojekthi adinga izinqwaba zemigqa ezinobukhulu obuncane, kanti amanye adinga inqwaba eyodwa enobubanzi obukhulu ukuze athwale umthwalo. Imininingwane kumele iguquguquke futhi ivumelane nezimo.
Zinjani lezi zinqwaba zamapayipi ensimbi zethu?
Ake siqonde ngqo ephuzwini. Leli qoqo lemikhiqizo lenziwe ngensimbi engu-A252 GRADE 2. Leli banga laziwa kakhulu ngamakhasimende amadala - linokuqina okuhle, lingamelana nengcindezi, futhi lifaneleka kakhulu ezindaweni ezingaphansi komhlaba lapho "ukungapheleli kungenakubekezelelwa". Sikala inqwaba ngayinye ngokwahlukile, hhayi nje ngenxa yesimo esisemthethweni, kodwa ukuze sinamathele ngokuqinile ezindinganisweni zemboni. Kuphela uma isisindo sinembile lapho amandla engathembeka khona.
Ngaphezu kwalokho, sisebenzisa inqubo ye-SSAW (Spiral Arc Welding). Inzuzo yale ndlela yokushisela ukuthi ukushisela kuyalingana, amandla aphezulu, futhi kwenza kube lula ukwenziwa kwezinqwaba ezinde ezilodwa. Izinqwaba ezinde zisho amalunga ambalwa, kanti amalunga ambalwa asho ingozi encane yokuvuza kanye namaphuzu ambalwa obuthakathaka besakhiwo. Kumapayipi egesi yemvelo angaphansi komhlaba, lokhu empeleni "kunciphisa umthwalo" wemisebenzi yesikhathi esizayo.
Ngubani iCangzhou Spiral Steel Pipe Group?
Mhlawumbe abanye babangani abasha abasazi kahle. Sitholakala eCangzhou, eSifundazweni saseHebei. Le fektri yasungulwa ngo-1993 futhi ibilokhu isebenza iminyaka engaphezu kwengu-30. Ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inabasebenzi abangu-680. Ikhiqiza amathani angu-400,000 amapayipi ensimbi ajikelezayo minyaka yonke, anenani lokukhipha elingu-1.8 billion yuan. Akuyona ifektri engenza konke kodwa ayikhethekile kunoma iyiphi into eyodwa. Kunalokho, igxile kumapayipi ensimbi ajikelezayo kanye nemikhiqizo yokumboza, futhi ihlinzeke ngezimpahla kumaphrojekthi amaningi wamandla ekhaya nakwamanye amazwe.
Ukuphetha
Uma okwamanje ukhetha izinqwaba zensimbi zamapayipi egesi angaphansi komhlaba, sicela ukhululeke ukusicela ishidi lemininingwane. Sine-A252 GRADE 2, SSAW, kanye nosayizi abahlukahlukene bamapayipi ensimbi. Nakuba ukuma kwesilinda kungase kubonakale kujwayelekile, uma kusetshenziswa endaweni efanele, kuba "umgogodla ongaphansi komhlaba" othembeke kakhulu.
Uma unemibuzo noma ufuna ukuxoxa ngamaphrojekthi athile, zizwe ukhululekile ukuxhumana nathi nganoma yisiphi isikhathi. Asivami ukusebenzisa izindlela zokuthengisa ezisezingeni eliphezulu, kodwa uma kukhulunywa ngemingcele yensimbi kanye nokwakhiwa kwesakhiwo, singakuchazela izinto ngokucacile.
