Iingqiniba zetyhubhu zentsimbi zenziwe ngamabakala entsimbi ye-austenitic, ngokuyintloko i-300 series (efana ne-304/304L kunye ne-316/316L), ebandakanya iipesenti eziphezulu ze-chromium kunye ne-nickel ukuseka i-self{5}}ukulungiswa komgangatho owenziweyo. Inkqubo yokwenziwa kwemveliso ibandakanya ukubunjwa okubandayo okanye ukutyhala kwe-mandrel kulandelwa sisisombululo se-annealing, unyango olubalulekileyo lobushushu olunyibilikisa ii-carbides eziqukunjelwa ngexesha lokwenziwa kwaye luthomalalise uxinzelelo lwangaphakathi.
IiNdawo zokuSebenza
Kumacandelo ekhemikhali kunye nepetrochemical, ezi zifakelo zisetyenziselwa ukuthutha imidiya ehlaselayo, kubandakanywa i-acids kunye ne-alkalis, apho i-carbon steel iya kungena kwi-oxidation esheshayo. Ukutya, isiselo, kunye namashishini axuba amayeza axhomekeke kwindawo -engenamaqhuqhuva, ecocekileyo yomgangatho ophezulu{2}}wengqiniba yentsimbi engenastainless ukunqanda ukuqokeleleka kwebhaktiriya kunye nokumelana nokuqina kweCIP (Coca{3}}kwi{4}}kwindawo) imigaqo. Ukongeza, i-molybdenum-evelisa amabanga (afana ne-316) zizinto eziqhelekileyo kubunjineli baselwandle kunye namaqonga aphesheya konxweme ngenxa yokuxhathisa okuphuculweyo kwi-chloride{8}}i-pitting eyenziwe kunye ne-corrosion kwindawo yamanzi etyuwa.
Izatifikethi kunye neMigangatho
Iiprothokholi zethu zokuvelisa zibambelela ngokungqongqo kwimigangatho yamazwe ngamazwe efana ne-ASTM A403, ASME B16.9, kunye neenkcukacha zeDIN. Sisebenza phantsi kwe-ISO9001 yolawulo lomgangatho kunye neenkqubo ze-ISO14001 zolawulo lokusingqongileyo, kwaye sibambe isiqinisekiso se-EU Pressure Equipment Directive (PED) sokuthotyelwa kokhuseleko. Ezi ziqinisekiso ziqinisekisa ukuba iindlela zethu zokuvelisa ziyahlangabezana nokulandeleka okungqongqo kunye neemfuno zokusebenza koomatshini eziyimfuneko kwiziseko zoshishino zehlabathi.
Umzi-mveliso wethu
Ifakwe kwiNdawo yoPhuhliso lweNqila yaseYanshan, indawo yethu yokuvelisa inika imigca yokulungisa intsimbi engenasiphene eyahlulwe ngokwasemzimbeni kwiindawo zentsimbi yekhabhoni ukuphelisa umngcipheko wongcoliseko lwe-ferrous. Sinikezela ngolungelelwaniso olubanzi kuyo yonke i-odolo yetyhubhu yengqiniba yentsimbi engatyiwayo, kuquka irediyasi egobileyo (irediyasi emfutshane okanye ende),{1}}ii-engile ezingekho mgangathweni, kunye nobungqingqwa bodonga obungafaniyo ukuhambelana nemizobo yeisometric echanekileyo. Imisebenzi yethu ye-wholesale ixhaswa ngamanyathelo okulawula umgangatho ongqongqo, kusetyenziswa itekhnoloji ye-Positive Material Identification (PMI) kunye novavanyo lwe-hydrostatic ukuqinisekisa ukubunjwa kweekhemikhali kunye noxinzelelo loxinzelelo ngaphambi kokuthunyelwa.
Imibuzo Ebuzwa Rhoqo (FAQ)
Q: Yintoni umahluko kubugcisa phakathi 304 yaye 316 grade engqinibeni?
A: IBakala 304 yingxubevange eqhelekileyo ukuxhathisa umhlwa jikelele. IBanga le-316 liqulethe ukongezwa kwe-2-3% ye-molybdenum, ephucula kakhulu ukuxhathisa i-chlorides kunye ne-dilute sulfuric acid, okwenza kube yinto ebalulekileyo kwiindawo zaselwandle okanye ezinobundlobongela.
Umbuzo: Ngaba unikezela ngeengxelo ze-Positive Material Identification (PMI)?
A: Ewe. Ukuqinisekisa ukubunjwa kweekhemikhali ezichanekileyo, sisebenzisa izibhamu zokuvavanya i-PMI kwiimveliso ezigqityiweyo. Sinikezela ngezi ngxelo kunye neSiqinisekiso soVavanyo lweMill (MTC) ngokwemigangatho ye-EN 10204 3.1.
Umbuzo: Ngaba unyango lobushushu lusetyenziswa emva kwenkqubo yokwenza?
A: Ewe. Siqhuba unyango lwe-annealing yobushushu kuzo zonke izixhobo zentsimbi engenasici emva kokwenza. Oku kubuyisela ukuxhathisa kwe-corrosion kunye neempawu zoomatshini ezinokuthi zitshintshwe ngexesha elibandayo lokusebenza okanye inkqubo yokugoba.
