Uma usanda kunakisisa ukwakhiwa kwamachweba noma amaphrojekthi amanzi ajulile, kungenzeka ukuthi uphawulile ukuthambekela: ububanzi bamapayipi ensimbi asetshenziselwa izinqwaba buyanda kakhulu.
Lokhu akuyona inkohliso. Njengoba ubukhulu bemiklamo yengqalasizinda bukhula, ikakhulukazi kumaphrojekthi afana nama-terminals ajulile, isidingo sezisekelo zezinqwaba ezinkulu sikhuphuke ngokushesha. Uma ububanzi bukhulu, amapayipi ajwayelekile anodonga oluqondile awafaneleki kahle, futhi abantu abaningi baphendukela ekunakeni amapayipi ahlanganisiwe ajikelezayo.
Kodwa lapho ububanzi bukhula, kuvela izinkinga.
Amapayipi ahlanganisiwe anobubanzi obukhulu asetshenziswa ezisekelweni zezinqwaba. Umthamo wawo wokuthwala imithwalo ngokuvamile awuyona inkinga. Okubangela ubuhlungu bekhanda ngempela imininingwane emibili: eyodwa ukuthi ngabe imininingwane iyafana yini, kanti enye ukuthi amalunga angafinyelela yini ukuvala ngempela.
Lapha, kufanele sikhulume ngomklamo oyinhloko -Isivalo Esihlanganisiwe Kumapayipi Okufaka IzintamboKalula nje, lesi sakhiwo senzelwe ukubhekana nezinkinga zegebe ezingaba khona ezingase zenzeke ngesikhathi senqubo yokuxhuma nokucwilisa kwamapayipi amakhulu. Akuyona "ingcindezi" elula, kodwa kunalokho, ngesakhiwo esixhumene, sakha ibhande lokuvala eliqhubekayo ejoyintini. Ikakhulukazi ezindaweni zamanzi ajulile, lapho ingcindezi yamanzi angaphandle iphezulu khona futhi inhlabathi inomoya oqinile, ngaphandle kwe-seal exhumene ethembekile, kungenzeka kakhulu ukuthi ibangele izinkinga esikhathini eside sokusetshenziswa.
Kungani ukucaciswa kwamapayipi ahlanganisiwe ajikelezayo kuthinta umphumela wokuvala?
Abantu abaningi bacabanga ukuthi ukuvala kuhlobene kuphela nenqubo. Eqinisweni, ingqikithi itholakala ezinhlotsheni ezithile.Ukucaciswa Kwepayipi Elihlanganisiwe Elihlanganisiweinquma ukuma kwe-weld, indlela imichilo yensimbi ehlanganiswe ngayo, nokuthi isakhiwo esiqinile esixhumene singatholakala yini ekugcineni.
Uma i-Cangzhou Spiral Steel Pipe Group yethu inquma imininingwane, izofaka ngqo izidingo zokuvala okuxhumene esigabeni sokuklama. Isibonelo, i-engeli ye-spiral, ukuphakama komthungo we-weld, ukuma kokwelashwa komphetho we-steel strip - zonke lezi zici zizothinta ukuthi ukuvala okulandelayo "kungakhiya endaweni". Akuwona wonke amapayipi ahlanganisiwe afanelekela ukuvala okuxhumene. Uma imininingwane inganqunywanga kahle, noma ngabe ukushisela kwenziwa kahle kamuva, kuzoba yize.
Indlela esikwenze ngayo
Eminyakeni emibili edlule, izinqwaba zamapayipi ensimbi amakhulu esawahlinzeka ngephrojekthi ye-Deepwater Terminal zonke zaklanywa ngokuvalelana nokuvala okujwayelekile. Izinzuzo zamapayipi ahlanganisiwe ajikelezayo - ubude obungaguquki ngemitha kanye nokuvalela okufanayo - kuhambisana kahle nesakhiwo sokuvalelana, kwandise ubude besigaba sokuvalela futhi kunciphise inani lamalungu aphakathi.
Ngaphezu kwalokho, siqinisekisa ukuthi kuqoqo ngalinye lamaphayiphi, i-Spiral Welded Pipe Specification ikhombisa ngokucacile imingcele efanele yokuvala okuxhumene. Akukhona nje ukubhala igama elithi "interlocking", kodwa empeleni kubhala uhlobo lomsele, ukubekezelelana, kanye nobubanzi bamandla okukhiya ephepheni. Lapho amakhasimende ethola imikhiqizo futhi enza ukuhlanganiswa endaweni, angazizwa ngokucacile ukuthi ikhiyiwe kahle endaweni yayo, futhi ifanelana kahle.
Ngokuphathelene nathi
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. yasungulwa ngo-1993 eCangzhou, eSifundazweni saseHebei. Ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inabasebenzi abangu-680. Ikhiqiza amathani angu-400,000 amapayipi ensimbi ajikelezayo minyaka yonke, anenani lomkhiqizo elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8. Ihlale igxile kumapayipi ensimbi ajikelezayo kanye nemikhiqizo yokumboza. Akuzona zonke izinto ezingakhiqizwa, kodwa emkhakheni wamapayipi ahlanganisiwe ajikelezayo, kusukela ezintweni zokwakha kuya ezicacisweni kuya ezivalweni ezixhumene, besilokhu sicophelela kakhulu.
Uma wenza iphrojekthi ehilela izisekelo ezinkulu zamapayipi, ikakhulukazi ezindaweni ezijulile, kunconywa ukuthi unake kakhulu amapayipi e-Interlock Seal On Piling kanye ne-Spiral Welded Pipe Specification. Uma imininingwane isilungile futhi ukuvalwa kwenziwe kahle, ungaqiniseka ngempela uma amapayipi esegqitshwe.
Uma unemibuzo, zizwe ukhululekile ukubuza ngqo. Akukho ukukhuluma okungenamsebenzi, akukho ukuncenga okuphoqelelwe. Singaxoxa ngobuchwepheshe, imininingwane, noma ukwakhiwa kwasendaweni.
