Isingeniso Somkhiqizo
Sethula ipayipi lethu legesi elihlanganisiwe elenziwe ngendlela ebandayo, umkhiqizo wekhwalithi ephezulu owenzelwe ukuhlangabezana nezindinganiso zekhwalithi ephezulu kanye nokusebenza. Enziwe ngensimbi ye-A252 Grade 1, amapayipi ethu akhiqizwa kusetshenziswa izindlela zokushisela ze-arc ezingaphansi kwamanzi ezithuthukisiwe ezimbili ukuqinisekisa amandla nokuqina okumangalisayo. Ipayipi ngalinye lenziwa ngokuhambisana ngokuqinile nezindinganiso ze-ASTM A252 ezisungulwe yi-American Society for Testing and Materials (ASTM), okuqinisekisa ukuthembeka nokuphepha kwezidingo zakho zokuthutha igesi.
Okwethuisakhiwo esihlanganisiwe esenziwe ngobandayoAmapayipi egesi afanelekela izinhlelo zokusebenza ezahlukahlukene, okuhlanganisa nezimboni zokwakha, ingqalasizinda kanye nezamandla. Ukuhlanganiswa kwezinto ezisezingeni eliphezulu kanye namasu okukhiqiza athuthukile kuqinisekisa ukuthi amapayipi ethu awagcini nje ngokuhlangabezana nezindinganiso zemboni, kodwa futhi ayadlula, okukunikeza izixazululo zamapayipi egesi ezinokwethenjelwa.
Inzuzo yomkhiqizo
Enye yezinzuzo ezibalulekile zezakhiwo zethu ezihlanganisiwe ezakhiwe ngokubandayo isilinganiso sazo esihle kakhulu samandla nesisindo. Ukusetshenziswa kwensimbi ye-A252 Grade 1 kudala uhlaka oluqinile olungamelana nokucindezeleka okuphezulu nezimo ezimbi kakhulu, okwenza lube luhle kakhulu ekuthuthweni kwegesi yemvelo. Ngaphezu kwalokho, indlela yokushisela i-arc engaphansi kwamanzi kabili yandisa ukuqina kwamalunga futhi inciphisa amathuba okwehluleka nokuvuza. Lokhu kuthembeka kusho izindleko zokulungisa eziphansi kanye nokuphepha okukhulu kwabasebenzisi bokugcina.
Ngaphezu kwalokho, ifektri yethu itholakala eDolobheni laseCangzhou, eSifundazweni saseHebei, futhi ibilokhu isebenza kusukela ngo-1993, ihlanganisa indawo engamamitha-skwele angu-350,000. Njengoba sinempahla ephelele engu-RMB million 680 kanye nabasebenzi abazinikele abangu-680, sizibophezele ekukhiqizeni imikhiqizo esezingeni eliphezulu ehlangabezana nezidingo zokwakha zesimanje.
Isicelo
Ifektri yethu itholakala eCangzhou, eSifundazweni saseHebei futhi ibilokhu iyigama elithembekile embonini selokhu yasungulwa ngo-1993. Ifektri ihlanganisa indawo engamamitha-skwele angu-350,000, ifakwe ubuchwepheshe obuthuthukisiwe kakhulu futhi inabasebenzi abazinikele abangu-680. Njengoba sinempahla ephelele engu-RMB 680 million, sizibophezele ekugcineni amazinga aphezulu ekhwalithi nokusebenza kahle ezinqubweni zethu zokukhiqiza.
Amapayipi ethu ensimbi ahlangabezana nezimiso eziqinileI-ASTM A252indinganiso ebekwe yi-American Society for Testing and Materials (ASTM). Lokhu kuhambisana kuqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zokuphepha nokusebenza ezidingekayo, okunikeza onjiniyela kanye nabakhi ukuthula kwengqondo. Kungakhathaliseki ukuthi usebenza kuphrojekthi enkulu yengqalasizinda noma umsebenzi omncane wokwakha, izakhiwo zethu ezihlanganisiwe ezibandayo zizohlala isikhathi eside.
Ukushoda Komkhiqizo
Inqubo yokukhiqiza ingaba yinkimbinkimbi kakhulu futhi idle isikhathi kunezinye izindlela, okungase kuholele ezindleko zokuqala eziphezulu. Ngaphezu kwalokho, yize insimbi ye-A252 Grade 1 iqinile futhi ihlala isikhathi eside, ingase ingafaneleki kuzo zonke izindawo, ikakhulukazi lezo ezigqwala kakhulu, ngaphandle kokuthi iphathwe kahle.
Imibuzo Evame Ukubuzwa
Umbuzo 1. Siyini isakhiwo esihlanganisiwe esenziwe ngokubandayo?
Izakhiwo ezihlanganisiwe ezakhiwe ngokubandayo ziyizingxenye zensimbi ezakhiwe ekushiseni kwegumbi bese zihlanganiswa ndawonye ukuze kwakheke uhlaka oluqinile noluhlala isikhathi eside olufanele ukusetshenziswa okuhlukahlukene.
Umbuzo 2. Kungani ukhethe insimbi yebanga lokuqala ye-A252?
Insimbi ye-A252 Grade 1 yaziwa ngokushibilika kwayo okuhle kakhulu kanye nokuqina, okwenza ibe yindawo ekahle kakhulu yokusetshenziswa kwesakhiwo, ikakhulukazi emapayipini egesi namafutha.
Umbuzo 3. Kubaluleke ngani indlela yokushisela i-arc engaphansi kwamanzi kabili?
Le ndlela inikeza ama-weld asezingeni eliphezulu aneziphambeko ezimbalwa, okuqinisekisa ubuqotho kanye nobude besakhiwo esi-welded.
Umbuzo 4. Uqinisekisa kanjani ukuthi uyahambisana nezindinganiso ze-ASTM?
Imikhiqizo yethu ihlolwe ngokucophelela futhi iqinisekiswe ngokwezindinganiso ze-ASTM A252, okukunikeza ukuzethemba ngekhwalithi nokusebenza kwayo.
