Ukubaluleka Kwepayipi Elisahliweyo Nelashiselwe Kungqalasizinda Yesimanje
Enkabeni yeCangzhou, eSifundazweni saseHebei, kuhlezi isigayo sensimbi obekuyitshe legumbiSaw Welded Pipeimboni kusukela yasungulwa ngo-1993. Lesi sikhungo, esihlanganisa ama-square metres angu-350,000, sinempahla ephelele yezigidi ezingu-680 zama-RMB futhi siqashe abasebenzi abazinikele abangama-680. Phakathi kwemikhiqizo yayo eminingi kukhona amapayipi asaha nashiselwe, okuyingxenye ebalulekile yengqalasizinda yesimanje, ikakhulukazi ekuthuthweni kwamanzi angaphansi komhlaba.
Amapayipi amanzi angaphansi komhlaba abalulekile ukuze kuthuthwe amanzi ngendlela efanele nangokwethembeka ezifundeni ezihlukahlukene. Bakha umgogodla wezinhlelo zethu zokuhlinzeka ngamanzi, okuqinisekisa ukuthi imiphakathi iyafinyelela kulo mthombo obalulekile. Impahla ekhethelwe la mapayipi ibalulekile, njengoba kufanele imelane nezingcindezi zemvelo kanye nezingcindezi zamanzi awathuthayo. Enye yezinketho ezidume kakhulu kule ndawo ipayipi lensimbi elishiselwe nge-spiral, elidume ngamandla alo nokuqina.
Inhlanganisela ephelele yamandla nokuqina
Amapayipi okuhambisa amanzi angaphansi komhlaba abhekene nezinselele eziyinkimbinkimbi zemvelo: umfutho wenhlabathi, ukushaqeka kwamanzi, izingozi zokugqwala... Konke lokhu kubeka izidingo eziphezulu kakhulu ezintweni zamapayipi. Amapayipi ensimbi asontekile e-S235 JR kanye namapayipi asontekile e-arc angaphansi kwamanzi angu-X70 akhiqizwa ifektri yaseCangzhou aklanywe ngokunembile ukubhekana nalezi zinselele. Amapayipi ashiselwe ngamasaha, enziwe ngokulinganisa okunembile nezindlela zokushisela, awagcini nje ngokuba nobuqotho obuvelele besakhiwo, kodwa futhi namandla awo nokuqina kwawo kuwenza abe yinketho ekahle yokufakwa ngaphansi komhlaba isikhathi eside.
Ukukhiqiza okuguquguqukayo kanye nokusetshenziswa okubanzi
Inzuzo yobuchwepheshe be-sawing kanye ne-welding ilele ezingeni layo eliphakeme lokuguquguquka.Metal Pipe Weldingakhiqizwa ngensimbi imichilo yokushisela. Le ndlela ayiqinisekisi kuphela ukunemba okuphezulu kwemikhiqizo kodwa futhi yenza ngokwezifiso amapayipi anobubanzi obuhlukene nobukhulu bodonga ngokusho kwezidingo zephrojekthi. Kusukela ekuhanjisweni kwamanzi kamasipala kuya kumaphrojekthi amakhulu okonga amanzi, amapayipi ashiselwe ngamasaha angahlinzeka ngezixazululo ezenziwe ngendlela efanele ukuhlangabezana nezidingo zengqalasizinda eyahlukene.
Ukugcizelelwa okulinganayo kubekwa ezinzuzweni zezomnotho kanye nokusimama
Namuhla, ngezabelomali eziqinile, amapayipi ane-sawlded anikeza ibhalansi yenani elingavamile: amanani okuncintisana ngaphandle kwekhwalithi yokudela. Inqubo yokukhiqiza ephumelelayo ikwenza kube ukukhetha okuncanyelwayo kwamaphrojekthi angabizi kakhulu. Khonamanjalo, ukuqina kanye nokusebenziseka kabusha kwamapayipi ensimbi ye-carbon nakho kusabela esibizweni sentuthuko esimeme. Amapayipi anesaha afakwe kahle futhi anakekelwe angahlala amashumi eminyaka, enciphisa kakhulu imvamisa yokushintshwa nokumosheka kwezinsiza.
Ukubheka Ikusasa: Ukuqamba kanye Nesidingo Ukuthuthuka ndawonye
Ngokuthuthuka okuqhubekayo kobuchwepheshe bokukhiqiza kanye nesidingo esikhulayo sengqalasizinda esimeme, amathuba emakethe yamapayipi ashiselwe ngamasaha asezingeni eliphezulu abanzi kakhulu. Njengoba cishe iminyaka engamashumi amathathu yesipiliyoni kanye nokunqwabelana kwezobuchwepheshe, imboni yaseCangzhou izoqhubeka nokuzinikela ekuhlinzekeni imakethe ngemikhiqizo ehlangabezana noma edlula ngisho namazinga emboni, futhi isekele ukwakhiwa kwengqalasizinda e-China nasemhlabeni jikelele.
Amapayipi ashiselwe ngesaha awawona nje imikhiqizo yezimboni; futhi ziyisisekelo esibalulekile sokuqinisekisa ukuvikeleka kwemithombo yamanzi emiphakathini kanye nokusekela intuthuko yezenhlalakahle nezomnotho. Enqubeni yethu eqhubekayo yokuthuthuka kwezindawo zasemadolobheni nokwenza ingqalasizinda ibe yesimanje, ukukhetha izinto ezinjengamapayipi ashiselwe ngamasaha ahlanganisa amandla, ukuqina kanye nomnotho ngokungangabazeki kuwukutshalwa kwezimali okuhlakaniphile kwekusasa.
