Ifektri Eshibhile yase-China ASTM A335 P12 Ingxubevange Yensimbi Ipayipi/Ishubhu elingenamthungo
Inhloso yethu enkulu kuzoba ukunikeza amakhasimende ethu ubudlelwano bebhizinisi elincane obungathi sína futhi obunomthwalo wemfanelo, sinikeze ukunakekela komuntu siqu kubo bonkeA, ipayipi yensimbi engenamthungo. A335 P12 ipayipi lensimbi engenamthungo, Inkampani yethu inikeza uhla olugcwele kusukela ekuthengisweni kwangaphambili kuya kusevisi yangemuva kokuthengisa, kusukela ekuthuthukisweni komkhiqizo kuya ekucwaningweni kokusetshenziswa kokulungiswa, ngokusekelwe emandleni aqinile ezobuchwepheshe, ukusebenza komkhiqizo okuphakeme, amanani anengqondo kanye nesevisi ephelele, sizoqhubeka nokuthuthukisa, ukunikeza izixazululo nezinsizakalo ezisezingeni eliphezulu, nokukhuthaza ukubambisana okuhlala njalo namakhasimende ethu, intuthuko efanayo nokudala ikusasa elingcono.
Uhlolojikelele
Isicelo
Isetshenziswa kakhulu ukwenza ipayipi le-boiler yensimbi esezingeni eliphakeme, ipayipi elishintshana ngokushisa, ipayipi elinomfutho ophezulu we-petroleum kanye nemboni yamakhemikhali.
Ibanga Eliyinhloko
Ibanga eliphezulu ipayipi ingxubevange: P1,P2,P5,P9,P11,P22,P91,P92 njll
Ngepayipi lengxubevange i-A335, imakethe enkulu yiNdiya. NgeMakethe yaseNdiya ivamise ukudinga i-IBR. namuhla izobonisa i-IBR njengenkomba.
Imithethonqubo ye-Indian Boiler Regulations (INDIA BOILER REGULATIONS, ngemuva kwalokhu ebizwa ngokuthi yi-IBR) ibeka ngokucacile ukuthi ama-boilers, imikhumbi yokucindezela, amapayipi, ama-valve, izinto zokusetshenziswa (amapuleti, imigoqo, ama-castings, ama-forging) athunyelwa e-India kudingeka ukuthi ahlolwe yi-CBB. i-ejensi yokuhlola egunyaziwe. Abahloli abagunyaziwe benza ukubuyekezwa kwedizayini kanye nokuhlolwa kokuqondisa kwenqubo yokukhiqiza ngokuhambisana ne-IBR, futhi benze ukuhlolwa kokufakwa esizeni nokubhaliswa ngaphambi kokungena emakethe yaseNdiya. Ngesikhathi esifanayo, abakhiqizi badinga ukukhipha Amafomu e-IBR ahlukahlukene njengokukhiqiza, ukufakwa kanye nesitifiketi sempahla ngokuhambisana nezidingo ze-IBR. Ukugunyaza kungathunyelwa kuphela ngemva kokusayinwa yi-ejensi yokuhlola egunyaziwe.
I-Indian Boiler Code ikubeka ngokucacile ukuthi amabhayela nemikhumbi yokucindezela ekhiqizwa kwamanye amazwe ngaphandle kwase-India kudingeka ihlolwe i-IBR nesitifiketi, futhi izikhungo zokuhlola zezinkampani zangaphandle kufanele zigunyazwe yi-CBB. Ngakho-ke, ukudlulisa isitifiketi se-IBR "kuyipasipoti" yenkampani ukuthi ingene emakethe yaseNdiya.
Njengamanje, amaphrojekthi ezinkampani zobunjiniyela basekhaya eNdiya ikakhulukazi izitshalo zamandla ezizihlinzeka ngokwazo zezitshalo ze-electrolytic aluminium, nezinkampani zokutshala izimali nazo ziyangenelela. Imikhiqizo ehlobene nemikhumbi yokucindezela ngokuyinhloko: amaphrojekthi wamandla ashisayo, inkontileka evamile ye-EPC yezinkampani zobunjiniyela; ukuthekelisa okuqondile kwama-boilers, ama-steam turbines, insiza yesiteshi samandla kagesi, njll.; ezinye izitsha zokucindezela ezisetshenziswa ezimbonini ze-petrochemical; ama-valve, ukufakwa kwamapayipi nezinye izingxenye; amapayipi ensimbi, amapuleti ensimbi nezinye izinto zokusetshenziswa.
Ngosizo lolwazi olucebile lwesitifiketi somkhakha, Ukuhlolwa kwe-Yunquan kungahlinzeka ngezinsizakalo zokuhlola ezihlobene ne-IBR, ukuqeqeshwa okujwayelekile, ukuqeqeshwa kwezisebenzi, ukubonisana nobuchwepheshe obuhlobene nomshini wokushisela kanye nokucubungula izinsizakalo zokugunyaza ukufaneleka, futhi kukhiphe ukuthobelana okuhlobene ne-ejensi yokuhlola egunyaziwe ye-CBB. Izitifiketi, isibonelo, isitifiketi seFOMU, isitifiketi sokushisela se-IBR, njll.
