Iipayipi zethu zentsimbi zinemilo esisilinda ukuqinisekisa ukusasazwa komthwalo ofanelekileyo, ngelixa ubukhulu bodonga obuqhelekileyo buqinisekisa ukuqina kunye nokumelana neemeko zokusingqongileyo.
Xa ukhetha yethuUbungakanani bepayipi ye-ASTM A252iinkcukacha, utyala imali kwimveliso engapheleli nje ekuhlangabezaneni nemigangatho yoshishino, kodwa edlula kuyo. Ukuzinikela kwethu kumgangatho kunye nokuvelisa izinto ezintsha kuqinisekisa ukuba ufumana imveliso ethembekileyo, esebenzayo, kwaye elungiselelwe iimfuno zakho ezithile.
Inzuzo yeNkampani
Ikwintliziyo yeSixeko saseCangzhou, kwiPhondo laseHebei, umzi-mveliso wethu ube lilitye lesiseko kushishino lwentsimbi ukusukela oko yasekwa ngo-1993. Lo mzi-mveliso ugubungela indawo yeemitha zesikwere ezingama-350,000 kwaye uxhotyiswe ngobuchwepheshe kunye noomatshini abakumgangatho ophezulu, okusenza sikwazi ukuvelisa iimveliso zentsimbi ezikumgangatho ophezulu ezihlangabezana nemigangatho yamazwe ngamazwe. Ngeempahla zizonke ze-RMB 680 yezigidi, sinabasebenzi abanezakhono abangama-680 abazinikele ekuboneleleni ngokugqwesa kuyo yonke into esiyenzayo.
Inzuzo yemveliso
Okokuqala, imo yayo esisilinda ivumela ukusasazwa komthwalo ngokufanelekileyo, nto leyo eyenza ukuba ifaneleke kakhulu kwiziseko ezinzulu. Isakhiwo sentsimbi sibonelela ngamandla angaqhelekanga kunye nokuqina, siqinisekisa ukuba ezi nqwaba ziyakwazi ukumelana nemithwalo emikhulu kunye neemeko ezinzima zokusingqongileyo. Ukongeza, ukuguquguquka kwepayipi ye-ASTM A252 kuvumela ukuba isetyenziswe kwiintlobo ngeentlobo zezicelo, ukusuka kwiibhulorho ukuya kwizakhiwo, nto leyo ephucula ukuthandwa kwayo kwiinjineli kunye nabakhi.
Ukusilela kweMveliso
Enye ingxaki ecacileyo kukuba kukho ukugqwala, ingakumbi kwiindawo ezinomswakama ophezulu okanye ezichaphazeleka ngamakhemikhali. Nangona iingubo zokukhusela zinokunciphisa le ngxaki, zinokunyusa iindleko zizonke kunye neemfuno zokulungisa.
Ukongeza, inkqubo yokuvelisaI-ASTM A252umbhobho unokuba luncedo kakhulu kwizixhobo, nto leyo enokuphakamisa inkxalabo malunga nokuzinza kunye nempembelelo kwindalo esingqongileyo.
Isicelo
Kwizakhiwo nakubunjineli bezakhiwo, ukukhethwa kwezinto kubalulekile ukuqinisekisa ukuthembeka kunye nobude besakhiwo. Enye yezinto ezihlonitshwa kakhulu kushishino yipayipi ye-ASTM A252. Le nkcazelo igubungela iipali zepayipi zentsimbi zodonga ezizii-cylindrical, ezibalulekileyo kwiindlela ezahlukeneyo zokusebenza, ingakumbi kubunjineli besiseko.
Iinkcukacha ze-ASTM A252 zisebenza kwiipali zentsimbi ezisetyenziswa njengamalungu ahlala ethwele umthwalo okanye ukwenza iqokobhe leepali zekhonkrithi ezifakwe kwindawo yazo. Oku kuguquguquka kwenza ukuba zilungele ukusetyenziswa kwiziseko ezinzulu, apho zinokuxhasa imithwalo enzima kwaye zimelane namandla asecaleni. Iipali ziyafumaneka ngobukhulu obahlukeneyo, okuvumela iinjineli ukuba zikhethe ubungakanani obufanelekileyo ngokusekelwe kwiimfuno ezithile zeprojekthi.
Izicelo eziphambili zeepayipi ze-ASTM A252 ziquka iibhulorho, izakhiwo, kunye nezinye izakhiwo ezifuna iziseko ezinzulu. Ukukwazi kwazo ukumelana neemeko ezinzima zokusingqongileyo kunye nemithwalo enzima kuzenza zibe lukhetho olukhethwayo lweenjineli kunye nabakhi. Njengoko siqhubeka nokuvelisa izinto ezintsha nokuphucula iinkqubo zethu zokuvelisa, sizimisele ukubonelela abathengi bethu ngezisombululo zentsimbi ezinokuthenjwa nezihlala ixesha elide ukuhlangabezana neemfuno zabo ezithile.
