Isishwankathelo
Isicelo
Isetyenziswa ikakhulu ukwenza umbhobho webhoyila wensimbi ekumgangatho ophezulu, umbhobho otshintshiselwa ngobushushu, umbhobho woxinzelelo oluphezulu wepetroleum kunye neshishini lemichiza.
IBanga eliPhambili
IBanga lombhobho we-alloy okumgangatho ophezulu:P1,P2,P5,P9,P11,P22,P91,P92 njl.
Ngombhobho we-alloy A335, imarike engundoqo yiIndiya. KwiMarike yaseIndiya ihlala ifuna i-IBR. namhlanje izakubonisa i-IBR yereferensi.
I-Indian Boiler Regulations (I-INDIA BOILER REGULATIONS, emva koko ekubhekiselwa kuyo njenge-IBR) imigaqo ichaza ngokucacileyo ukuba iibhoyila, iinqanawa zoxinzelelo, iipayipi, iivalve, izinto eziluhlaza (iipleyiti, imivalo, ii-castings, i-forgings) ezithunyelwa eIndiya kufuneka zihlolwe yi-CBB. i-arhente yokuhlola egunyazisiweyo. Abahloli abagunyazisiweyo baqhuba uphononongo loyilo kunye nohlolo lwenkqubo yokwenziwa kohlolo ngokuhambelana ne-IBR, kwaye baqhube uphononongo lofakelo lwendawo kunye nokubhaliswa ngaphambi kokungena kwimarike yaseIndiya. Kwangaxeshanye, abavelisi kufuneka bakhuphe iiFom ze-IBR ezahlukeneyo ezifana nokuvelisa, ukufakela kunye nesiqinisekiso sezinto eziphathekayo ngokuhambelana neemfuno ze-IBR. Imvume ingangeniswa kuphela emva kokuba isayinwe yi-arhente egunyazisiweyo yokuhlola.
IKhowudi yeBoiler yaseIndiya icacisa ngokucacileyo ukuba iibhoyila kunye neenqanawa zoxinzelelo ezenziwe kumazwe angaphandle kweIndiya kufuneka zingene kuhlolo lwe-IBR kunye nesatifikethi, kwaye ii-arhente zokuhlola zomntu wesithathu kufuneka zigunyaziswe yi-CBB. Ke ngoko, ukupasa isatifikethi se-IBR "yipasipoti" yenkampani yokungena kwimarike yaseIndiya.
Okwangoku, iiprojekthi zeenkampani zobunjineli basekhaya eIndiya ikakhulu zibonelela ngokwazo ngezityalo zamandla e-electrolytic aluminiyam, kwaye iinkampani zotyalo-mali nazo ziyangenelela. Iimveliso ezinxulumene nemikhumbi yoxinzelelo ikakhulu: iiprojekthi zamandla e-thermal, isivumelwano se-EPC ngokubanzi kwiinkampani zobunjineli; ukuthunyelwa ngokuthe ngqo kweebhoyila, ii-injini zomphunga, i-axiliary station station, njl.; ezinye iinqanawa zoxinzelelo ezisetyenziswa kumashishini epetrochemical; iivalve, izixhobo zombhobho kunye nezinye izinto; imibhobho yentsimbi, iipleyiti zentsimbi kunye nezinye izinto eziluhlaza.
Ngoncedo lwamava esiqinisekiso soshishino olutyebileyo, uVavanyo lweYunquan lunokubonelela ngeenkonzo zokuhlola ezinxulumene ne-IBR, uqeqesho olusemgangathweni, uqeqesho lwabasebenzi, uthethwano lobugcisa kunye novavanyo, isiqinisekiso se-IBR esinxulumene ne-welder kunye nenkqubo yeenkonzo zokuvunywa kwesiqinisekiso, kunye nokukhupha ukuthotyelwa okunxulumene ne-arhente yokuhlola egunyazisiweyo ye-CBB. Izatifikethi, umzekelo, isatifikethi seFOMU, isatifikethi se-IBR sokuwelda, njl.
