DN2000 Duplex SS Tilting Disc ivalve yokujonga

I-Valve ye-Tilted Disc Check ilukhetho oluhle kakhulu lwamanzi akrwada, amanzi okupholisa kunye nokucocwa kwamanzi / ukusetyenziswa kwamanzi amdaka. I-contouring body contouring yayo, indawo yokuhamba i-40% inkulu kunobungakanani bombhobho obizwa ngokuba yi-hydrodynamic disc ukudibanisa ukubonelela ngelahleko ephantsi kakhulu yentloko kuyo nayiphi na i-valve yokuhlola eveliswe namhlanje.

Xa i-valve yokutshekisha i-disc isetyenziselwa amanzi olwandle okanye inkqubo yamanzi, i-duplex SS i-duplex iyona nto ingcono kakhulu yokuphucula ukusebenza kwayo.

Imathiriyeli ye-duplex yentsimbi ecocekileyo eneenkcukacha ezichazwe ngezantsi.

CE3MN(SS2507) Super Duplex Stainless Steel

I-CE3MN (i-UNS S32750), iyintsimbi ephindwe kabini, inokumelana ne-corrosion enkulu kune-Ss2205 kunye ne-18-8 Cr-Ni kunye ne-18-14-2 / ​​18-14-3 Cr-Ni-Mo intsimbi engenasici, esetyenziselwa inkonzo. kwiimeko zomhlwa.

Umgangatho weMpatho yokuCasa: I-ASTM A890 kunye ne-ASTM A995 iBanga le-5A: Uhlobo lwe-25Cr-7Ni-Mo-N; Ukusasa UNSJ93404; I-ACI CE3MN;

Elinye ibakala leMetal elifanayo kwisicelo esahlukileyo A789 /ASTM A790/ASTM A276:

Ii-UN ezisebenzayo ze-S32750; Ibakala elisebenzayo ss2507.A182 F53

EN: X2CrNiMoN 25-7-4: WNr 1.4410:

I-AFNOR Z5CND20.12M

I-ASTM A890/890M iNgcaciso yoMgangatho wokuCasa, i-lron-Chromium-Nickel-Molybdenum-Resistant-Corrosion, i-Duplex (i-Austenitic/Ferritic) kwi-Austenitic/Ferritic ye-General Applications A995/995M iMiba eMigangatho yokuCasa, i-Austenitic-Ferritic (iDuplex, i-Stainless Steel) Amacandelo

CE3MN Inkqubo yonyango lobushushu:

Ubushushu bufikelele kwi-2050 ngokukaCelsius [1120 ngokukaCelsius] ubuncinane, bambe ixesha elaneleyo lokufudumala kwiqondo lobushushu, iziko liphole liye kutsho kwi-1910°C, licime amanzi okanye liphole ngokukhawuleza ngezinye iindlela.

Ukuqina ≤HB300(HRC32

Ukuhlolwa kokungena kwedayi luhlobo lovavanyo lwe-NDT. Isetyenziselwa ngokukodwa ukukhangela iziphene ezingaphezulu, ezifana neentanda, i-porosity yomhlaba kunye nokuvuza kweentsimbi. Isekelwe kwisakhono solwelo olutsalwa kwisiphene ngesenzo se-capillary

Ngethuba lenkqubo yokuvavanya, icandelo lifakwe kwi-liquid penetrant. Oku kushiywe ukuba kufakwe kwimizuzu engama-30. Nakuphi na ukungena okugqithisileyo kuyasuswa phambi kokuba kusetyenziswe umphuhlisi omhlophe. Lo mphuhlisi unceda ukutsala umngeneleli ukusuka kwiziphene kumphezulu kwaye aveze naziphi na iziphene - inkqubo eyaziwa ngokuba 'kukopha'.

Emva kwexesha elifutshane, icandelo lihlolwe phantsi kokukhanya kwe-ultraviolet. Nakuphi na ukungafezeki kuya ku-fluoresce ngokuqaqambileyo kulo kukhanya.
