Inzuzo Yenkampani
Itholakala enkabeni yeDolobha laseCangzhou, eSifundazweni saseHebei, ifektri yethu ibilokhu iyinsika yemboni yensimbi selokhu yasungulwa ngo-1993. Le fektri ihlanganisa indawo engamamitha-skwele angu-350,000 futhi ifakwe ubuchwepheshe kanye nemishini yesimanje, okusenza sikwazi ukukhiqiza imikhiqizo yensimbi esezingeni eliphezulu ehlangabezana nezindinganiso zomhlaba wonke. Njengoba sinempahla elinganiselwa ku-RMB 680 million, sinabasebenzi abanamakhono abangu-680 abazinikele ekuhlinzekeni ngobuhle kuzo zonke izici zemisebenzi yethu.
Inzuzo yomkhiqizo
Okokuqala, ukuma kwayo okuyisilinda kuvumela ukusatshalaliswa komthwalo okuphumelelayo, okwenza kube kuhle kakhulu ekusetshenzisweni kwesisekelo esijulile. Isakhiwo sensimbi sinikeza amandla nokuqina okumangalisayo, okuqinisekisa ukuthi lezi zinqwaba zingakwazi ukumelana nemithwalo emikhulu kanye nezimo zemvelo ezinzima. Ngaphezu kwalokho, ukuguquguquka kwepayipi le-ASTM A252 kuvumela ukuthi lisetshenziswe ezinhlotsheni ezahlukahlukene, kusukela kumabhuloho kuya ezakhiweni, okuthuthukisa ukukhanga kwalo konjiniyela kanye nabakhi.
Ukushoda Komkhiqizo
Ububi obusobala ukuthi kungenzeka ukuthi kube nokugqwala, ikakhulukazi ezindaweni ezinomswakama ophezulu noma ukuchayeka kumakhemikhali. Nakuba izembozo zokuvikela zinganciphisa le nkinga, zingandisa izindleko eziphelele kanye nezidingo zokulungisa.
Ngaphezu kwalokho, inqubo yokukhiqiza yeI-ASTM A252Amapayipi angadinga izinsiza eziningi, okungase kuphakamise ukukhathazeka mayelana nokusimama kanye nomthelela emvelweni.
Isicelo
Ekwakhiweni nasekubunjiniyeleni bokwakha, ukukhethwa kwezinto kubalulekile ukuqinisekisa ubuqotho nobude besakhiwo. Enye yezinto ezihlonishwa kakhulu embonini yipayipi le-ASTM A252. Le ncazelo ihlanganisa izinqwaba zamapayipi ensimbi odongeni ayisilinda, abalulekile ezinhlotsheni ezahlukene zokusebenza, ikakhulukazi kubunjiniyela besisekelo.
Imininingwane ye-ASTM A252 isebenza ezinqwabeni zamapayipi ensimbi ezisetshenziswa njengamalungu ahlala njalo athwala imithwalo noma ukwakha igobolondo lezinqwabeni zekhonkrithi ezifakwe endaweni. Lokhu kuguquguquka kuzenza zilungele ukusetshenziswa ezisekelweni ezijulile, lapho zingasekela khona imithwalo esindayo futhi zimelane namandla aseceleni. Amapayipi atholakala ngobukhulu obuhlukahlukene, okuvumela onjiniyela ukuthi bakhethe usayizi ofanele ngokusekelwe ezidingweni ezithile zephrojekthi.
Izicelo ezinkulu zamapayipi e-ASTM A252 zifaka phakathi amabhuloho, izakhiwo, nezinye izakhiwo ezidinga izisekelo ezijulile. Amandla azo okubekezelela izimo zemvelo ezinzima kanye nemithwalo esindayo azenza zibe ukukhetha okukhethwayo konjiniyela kanye nabakhi. Njengoba siqhubeka nokuthuthukisa izinqubo zethu zokukhiqiza, sisalokhu sizibophezele ekuhlinzekeni amakhasimende ethu ngezixazululo zensimbi ezithembekile nezihlala isikhathi eside ukuze kuhlangatshezwane nezidingo zawo ezithile.
