Enkokola za ttanka ez’ekyuma ekitali kizimbulukuse zikolebwa okuva mu ddaala ly’ekyuma erya austenitic, okusinga 300 series (nga 304/304L ne 316/316L), ezirimu ebitundu ebinene ebya chromium ne nickel okuteekawo self-repairing passive surface layer. Enkola y’okukola etera okuzingiramu okukola mu nnyonta oba okusika mandrel nga kugobererwa solution annealing, enkola ey’ebbugumu enkulu esaanuusa carbides ezitonnye mu kiseera ky’okukola n’okumalawo okunyigirizibwa okw’omunda.
Ebitundu by’Okusaba
Mu bitundu by’eddagala n’eby’amafuta, ebikozesebwa bino bikozesebwa okutambuza emikutu egy’amaanyi, omuli asidi ne alkali, ekyuma kya kaboni gye kyandifudde omukka ogw’amangu. Amakolero g’emmere, ebyokunywa, n’eddagala geesigamye ku kifo ekitali-obutuli, obuyonjo obw’enkokola ya ttanka ey’ekyuma ekitali kizimbulukuse eky’omutindo ogwa waggulu-okuziyiza okukuŋŋaanyizibwa kwa bakitiriya n’okugumira enkola enkakali eya CIP (Clean-in-Place). Okugatta ku ekyo, ebika ebirina molybdenum-(nga 316) bitundu bya mutindo mu yinginiya w’ennyanja n’ebifo eby’oku nnyanja olw’obuziyiza bwabyo obw’amaanyi eri chloride-induced pitting and crevice corrosion mu mbeera z’amazzi ag’omunnyo.
Satifikeeti n’Emitindo
Enkola zaffe ez’okukola zigoberera nnyo omutindo gw’ensi yonna nga ASTM A403, ASME B16.9, ne DIN specifications. Tukola wansi w’enkola ya ISO9001 ey’okuddukanya omutindo n’enkola ya ISO14001 ey’okuddukanya obutonde, era tulina satifikeeti ya EU Pressure Equipment Directive (PED) olw’okugoberera obukuumi. Ebiwandiiko bino bikakasa nti enkola zaffe ez’okufulumya zituukiriza ebisaanyizo ebikakali eby’okulondoola n’okukola emirimu gy’ebyuma ebyetaagisa ku bikozesebwa mu makolero mu nsi yonna.
Ekkolero lyaffe
Esangibwa mu Yanshan County Development Zone, ekifo kyaffe eky’okufulumya ebyuma kirimu layini ezeetongodde ez’okulongoosa ekyuma ekitali kizimbulukuse ezaawuddwa mu mubiri okuva mu bitundu ebirimu ekyuma kya kaboni okumalawo obulabe bw’obucaafu bw’ekyuma. Tuwa okulongoosa okujjuvu ku buli ndagiriro y’enkokola ya ttanka ey’ekyuma ekitali kizimbulukuse, omuli radius ez’enjawulo ez’okubeebalama (radius ennyimpi oba empanvu), enkoona ezitali -standard, n’obuwanvu bwa bbugwe obw’enjawulo okukwatagana n’ebifaananyi ebituufu ebya isometric. Emirimu gyaffe egya wholesale giwagirwa enkola enkakali ey’okulondoola omutindo, nga tukozesa tekinologiya wa Positive Material Identification (PMI) n’okugezesa amazzi okukakasa obutonde bw’eddagala n’ebipimo bya puleesa nga tetunnasindikibwa.
Ebibuuzo Ebitera Okubuuzibwa (FAQ) .
Q: Njawulo ki eri mu by’ekikugu wakati w’enkokola za ddaala 304 ne 316?
A: Grade 304 ye aloy eya standard eri okuziyiza okukulukuta okwa bulijjo. Ekibiina kya 316 kirimu ekirungo kya molybdenum eky’okugattako ebitundu 2-3%, ekiyamba ennyo okuziyiza chlorides ne dilute sulphuric acid, ekigifuula ekyetaagisa mu mbeera z’ennyanja oba ez’eddagala ery’amaanyi.
Q: Owa lipoota z’okuzuula ebintu ebirungi (PMI)?
A: Yee. Okukakasa nti eddagala lituufu, tukozesa emmundu ezigezesa PMI ku bintu ebiwedde. Tuwa lipoota zino wamu ne Mill Test Certificate (MTC) okusinziira ku mutindo gwa EN 10204 3.1.
Q: Okulongoosa mu bbugumu kukozesebwa oluvannyuma lw’okukola?
A: Yee. Tukola solution annealing heat treatment ku bikozesebwa byonna eby’ekyuma ekitali kizimbulukuse oluvannyuma lw’okukola. Kino kizzaawo okuziyiza okukulukuta n’eby’ebyuma ebiyinza okukyusibwa mu nkola y’okukola oba okubeebalama mu nnyonta.
