Ukuqonda Ipayipi le-ASTM A252: Ingxenye Ebalulekile Ekufakeni Izicelo
Emhlabeni wokwakha kanye nobunjiniyela bomphakathi, ukubaluleka kwezinto ezinokwethenjelwa akukwazi ukweqiwa. Eminyakeni yakamuva,Ipayipi le-ASTM A252uthole ukunakwa okukhulu. Lokhu kucaciswa kubaluleke kakhulu kumaphrojekthi abandakanya umsebenzi wokunqwabelanisa, njengoba ubuqotho nokuqina kwezinto ezisetshenziswayo kuthinta ngqo impumelelo noma ukwehluleka kwesakhiwo sokwakha.
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. itholakala enkabeni yedolobha laseCangzhou, esifundazweni saseHebei. Ingumkhiqizi wamapayipi ashiselwe ohamba phambili kusukela yasungulwa ngo-1993. Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele yezigidi ezingu-RMB 680, futhi inabasebenzi abanekhono nabaqeqeshiwe abalinganiselwa ku-680. Isipiliyoni esicebile nengqalasizinda eqinile yenza inkampani ikhiqize amapayipi ekhwalithi ephezulu e-ASTM A252 ahlangabezana nezidingo eziqinile zemboni yezokwakha.
Ukucaciswa kwe-ASTM A252 kuhlanganisa izinqwaba zamashubhu zensimbi ezingodongeni ezinomumo oyisilinda. Lezi zinqwaba zenzelwe ukusetshenziswa njengamalungu ahlala unomphela athwala imithwalo noma njengezindlu zezinqwaba zikakhonkolo ezifakwe endaweni. Lo msebenzi ombaxambili ubalulekile ekuqinisekiseni ukuthi ubuqotho besakhiwo sesisekelo buyagcinwa esikhathini eside. Ezicelweni lapho izimo zomhlabathi zingase zidinge khona, ukusetshenziswa kwezinqwaba zamashubhu ze-ASTM A252 kunenzuzo ikakhulukazi ngoba zinikeza amandla nokuzinza okudingekayo ukusekela imithwalo esindayo.
Ukusebenza okuvelele nokuqina okuhlala isikhathi eside
I-Astm A252 Pipe Dimensionsama-piles anezinzuzo ezilandelayo ezibalulekile:
Yenziwe ngensimbi enamandla amakhulu, inomsebenzi omuhle kakhulu wokuthwala umthwalo
Ukwelashwa okukhethekile kokuqeda ukugqwala, kulungele izindawo ezinokhahlo njengokuswakama nezimo ezinosawoti we-alkali
Ingasetshenziswa njengengxenye ehlala njalo ethwala umthwalo noma igobolondo lenqwaba yekhonkrithi
Yehlisa inani lamalunga asendaweni futhi uthuthukise amandla esakhiwo jikelele
Enye yezinzuzo eziyinhloko zokusebenzisa amapayipi e-ASTM A252 ekuqoqeni izinhlelo zokusebenza amandla awo okumelana nezimo zemvelo ezinzima. Insimbi esetshenziswa kula mapayipi iphathwa ukuze imelane nokugqwala, iqinisekise ukuthi iphila isikhathi eside futhi inciphisa izindleko zokunakekela isikhathi eside. Lokhu kubaluleke kakhulu ezindaweni lapho amapayipi angase abekwe endaweni emanzi noma eqinile yenhlabathi.
Ngaphezu kwalokho, inqubo yokukhiqiza yeCangzhou Spiral Steel Pipe Group Co., Ltd. ilandela izinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ukuthi ipayipi ngalinye elikhiqizwayo lihlangabezana nezindinganiso eziphakeme kakhulu zemboni. Lokhu kuzibophezela kwekhwalithi akugcini nje ngokwenza ngcono ukusebenza kwepayipi, kodwa futhi kukhulisa ukuzethemba kosonkontileka nonjiniyela abathembele kulezi zinto kumaphrojekthi abo.
Sekukonke, ipayipi le-ASTM A252 liyingxenye ebalulekile yemboni yezokwakha, ikakhulukazi ekufakeni izicelo. Ngobuchwepheshe nezinsiza ze-Cangzhou Spiral Steel Pipe Group Co., Ltd., amakhasimende angaqinisekiswa ngokuthola amapayipi ashiselwe asezingeni eliphezulu ahlangabezana nezidingo zawo ezithile. Njengoba isidingo sezinto zokwakha ezihlala isikhathi eside nezithembekile siqhubeka sikhula, ipayipi le-ASTM A252 ngokungangabazeki lizodlala indima ebalulekile ekulolongeni ukuthuthukiswa kwengqalasizinda yesikhathi esizayo. Kungakhathaliseki ukuthi uhileleke kuphrojekthi enkulu yokwakha noma encane, cabangela izinzuzo zokufaka ipayipi le-ASTM A252 kusixazululo sakho sesisekelo.
