Ukubaluleka Kwepayipi elisahliweyo kanye Neshiselwe Ingqalasizinda Yesimanje, Enkabeni yeCangzhou, eSifundazweni sase-Hebei, kuhlezi indawo yokugaya insimbi ebilokhu iyisisekelo semboni yamapayipi ensimbi kusukela yasungulwa ngo-1993. Le nkampani ihlanganisa amamitha-skwele angu-350,000, izidla ngempahla eyizigidi ezingu-680 zama-RMB, futhi iqashe abasebenzi abangu-68. Phakathi kwemikhiqizo yayo eminingi kukhona amapayipi asaha nashiselwe, okuyingxenye ebalulekile yengqalasizinda yesimanje, ikakhulukazi ekuthuthweni kwamanzi angaphansi komhlaba.
Ngaphansi komhlabaSaw Welded Pipezibalulekile ukuze kuthuthwe amanzi ngendlela efanele nangethembekile ezindaweni ezihlukahlukene. Bakha umgogodla wengqalasizinda yethu yesimanje, ukuqinisekisa ukuthi amanzi ahlanzekile afinyelela emakhaya, amabhizinisi nasezindaweni zezolimo. Ukukhethwa kwempahla yala mapayipi kubalulekile, njengoba kufanele amelane nezingcindezi zemvelo engaphansi komhlaba kuyilapho egcina ubuqotho bawo besikhathi eside. Enye yezinketho ezidume kakhulu zalezi zinhlelo zokusebenza ipayipi lensimbi elishiselwe nge-spiral, elidume ngamandla alo nokuqina.
I-S235 JR spiral steel pipe kanye ne-X70 SSAW (Spiral Submerged Arc Welded) ipayipi likalayini imikhiqizo emibili evamile esetshenziswa kabanzi ezinhlelweni zamapayipi amanzi angaphansi komhlaba. Ipayipi le-S235 JR lihlonishwa kakhulu ngenxa yezakhiwo zalo ezinhle kakhulu zemishini, okulenza lilungele ukusetshenziswa okuhlukahlukene, okuhlanganisa nokuthuthwa kwamanzi. Ikhono layo lokumelana ne-deformation ngaphansi kwengcindezi liqinisekisa ukuthi lihlangabezana nezidingo zezindawo ezingaphansi komhlaba.
Namuhla, njengoba kusheshiswa inqubo yokufudukela emadolobheni, uhlelo oluthembekile lokudluliswa kwamanzi angaphansi komhlaba seluyisihluthulelo sokuqinisekisa ukuphila kwabantu. Njengebhizinisi elihamba phambili embonini yokukhiqiza amapayipi ensimbi, imboni yensimbi ethile eDolobheni laseCangzhou, eSifundazweni sase-Hebei, ibihlinzeka ngamapayipi asebenza kahle kakhulu eSaw Welded engqalasizinda yomhlaba wonke kusukela yasungulwa ngo-1993. Amapayipi ayo ensimbi ayi-S235 JR kanye namapayipi asongezelayo angaphansi kwamanzi angu-X70, anemisebenzi yawo esezingeni eliphezulu, asephenduke impahla ewumshini owumgogodla.
1. Amandla aphezulu kanye nokumelana nokugqwala kuqinisekisa ukuphepha kokudluliswa kwamanzi isikhathi eside. Ipayipi elivunguzayo le-S235 JR: Ifaka ukumelana okuhle kakhulu nokuguqulwa kwengcindezi futhi ifanele indawo eyinkimbinkimbi ye-geological, iqinisekisa ukusebenza okuzinzile kwesikhathi eside kwepayipi. Ipayipi le-X70 SSAW: Lenziwe ngensimbi enamandla amakhulu kanye nobuchwepheshe bokushisela okuvunguzayo, alikwazi ukumelana nokucindezela futhi limelana nokugqwala, lilungele ukudluliswa kwamanzi amabanga amade kanye nezindawo ezinokhahlo.
2. Ubuchwepheshe obusezingeni eliphezulu obuhlanganiswe nokulawulwa kwekhwalithi okuqinile kwakha uhlelo lwamapayipi oluzinzile. Le fekthri isebenzisa ubuchwepheshe be-spiral submerged arc welding (SAW) ukuze kuzuzwe ukukhiqizwa okusebenzayo kwamashubhu anobubanzi obukhulu, anezindonga ezincane, isebenzise kahle ukusetshenziswa ngenkathi iqinisekisa amandla. Ngokubambisana nethimba eliqeqeshiwe labantu abangu-680 kanye nomugqa wokukhiqiza wesimanje obiza ama-yuan ayizigidi ezingu-680, siqinisekisa ukuthi wonke amapayipi ensimbi ahlangabezana nezindinganiso zamazwe ngamazwe, anikele ekuthuthukisweni kwengqalasizinda eluhlaza. Ngokuthuthukiswa kwezidingo zokulawulwa kwemithombo yamanzi emhlabeni wonke, amapayipi ashiselwe ngesaha eSikhungo Sensimbi saseCangzhou azoqhubeka nokuhlinzeka ngezixazululo ezihlala isikhathi eside nezingabizi kakhulu zokuthutha ngamanzi kamasipala, ezolimo kanye nezimboni, kugqugquzelwe ukwakhiwa kwengqalasizinda esimeme yokonga amanzi.
amapayipi asaha futhi ashiselwe akhiqizwa yi-Cangzhou Steel Mills ayingxenye ebalulekile yezinhlelo zamanzi angaphansi komhlaba. I-S235 JR kanye ne-X70 spiral arc ashiselwe amapayipi angaphansi kwamanzi asontekile, anezakhiwo zawo ezinhle kakhulu zemishini nokumelana nezici zemvelo, abalulekile ekuqinisekiseni ukuthuthwa kwamanzi ngendlela efanele. Uma sibheka phambili, ukubaluleka kwale mikhiqizo kuzoqhubeka nokukhula, okugqamisa isidingo semboni yamapayipi ensimbi sokukhiqiza izinga eliphezulu nezisombululo ezintsha.
