Akukho nanye kwezi zinto ingcono kakhulu kwihlabathi liphela. I-2205 ingcono kakhulu xa inamandla aphezulu, ixhathisa ukugqwala kwe-chloride kunye nokumelana nokuqhekeka koxinzelelo. I-316L ingcono xa isetyenziswa kwinkonzo yokugqwala ngokubanzi, kulula ukuyila, ukufumaneka kwayo ngokubanzi kunye nexabiso eliphantsi xa kungekho chloride inobungozi.

2. Ingaba i-2205 inamandla kune-316L?

Ewe. Ibha yentsimbi engagqwaliyo ye-2205 ephindwe kabini idla ngokuba namandla aphezulu okuvelisa kune-316L. Oku kuyenza ifaneleke kwiishafti, izibophelelo, iindawo zokumpompa, izinto zevalvu kunye neendawo ezithwala umthwalo apho amandla abalulekileyo.

3. Zeziphi izinto ezinokumelana nokugqwala okungcono?

I-2205 ngokubanzi inokumelana ngcono nokuqhekeka kwe-pitting, cravice corrosion kunye ne-chloride stress corrosion kune-316L. Nangona kunjalo, kwiindawo eziphakathi, i-316L inokwanela kwaye ingabizi kakhulu. Kwinkonzo enzima kakhulu, ii-super duplex 2507 okanye ii-nickel alloys zinokuqwalaselwa.

4. Ingaba i-2205 ibiza kakhulu kune-316L?

Kwiimeko ezininzi, i-2205 ibiza ngaphezulu kwe-316L ngenxa yomxholo we-alloy, ulawulo lwemveliso kunye nenqanaba lokusebenza. Nangona kunjalo, inokunciphisa iindleko zomjikelo wobomi kwiindawo ezinzima ze-chloride kuba inokubonelela ngobomi obude benkonzo kunye namandla aphezulu oomatshini.

5. Ngaba intsimbi engagqwaliyo ye-2205 ephindwe kabini ingadityaniswa?

Ewe, i-2205 ingadityaniswa, kodwa ukudityaniswa kwe-duplex kufuna ulawulo olufanelekileyo lokufaka ubushushu, ukukhethwa kwezalisa kunye nolawulo lokulinganisela kwe-ferrite/austenite. I-316L ngokubanzi kulula ukuyidibanisa, kodwa i-2205 ikhethwa xa kufuneka amandla aphezulu kunye nokumelana ne-chloride.

6. Abathengi banokuqinisekisa njani ukuba izinto ezisetyenzisiweyo ziyi-2205 okanye i-316L?

Abathengi kufuneka bajonge i-EN 10204 3.1 MTC, inombolo yobushushu, inombolo ye-UNS, ukwakheka kweekhemikhali kunye nophawu lwemveliso. Uvavanyo lwe-PMI lucetyiswa kakhulu kuba lunokuqinisekisa umxholo we-chromium, i-nickel kunye ne-molybdenum kwaye luncede ekuchongeni umgangatho ochanekileyo wentsimbi engagqwaliyo.

7. Loluphi ulwazi olufunekayo ukuze ufumane isicatshulwa esikhawulezileyo?

Uphando olupheleleyo kufuneka luquke ibakala, inombolo ye-UNS, umgangatho, ububanzi, ubude, ubungakanani, ukugqitywa komphezulu, ukunyamezela, imfuneko yovavanyo, imfuneko ye-MTC, izibuko lendawo ekuyiwa kuyo kunye nemfuneko yokupakisha. Umzekelo: Ibha ejikelezileyo yentsimbi engagqwali ye-ASTM A276 UNS S32205 2205, ububanzi obuyi-35 mm, ubude obuyi-3000 mm, umphezulu oxotyulweyo, uvavanyo lwe-EN 10204 3.1 MTC kunye ne-PMI.

Isiphelo

I-2205 Duplex Stainless Steel Bar kunye ne-316L Stainless Steel Bar zombini zizinto ezibalulekileyo ezingagqwaliyo, kodwa zikhethelwe iimeko ezahlukeneyo zenkonzo. I-316L ifanelekile kwizinto ezixhathisayo ukugqwala ngokubanzi, izixhobo zokutya nezamayeza, iindawo ezisemgangathweni ezenziwe ngomatshini kunye nezicelo ezinobuzaza bexabiso. I-2205 ifanelekile kwizinto ezinamandla aphezulu, iindawo ze-chloride, izixhobo zaselwandle, iinkqubo zokukhupha ityuwa, ukusetyenziswa kweoyile negesi kunye nezinto ezifuna ukumelana ngcono nokuqhekeka koxinzelelo lokugqwala.

Ukuze abathengi baphumelele ekuthengeni, kufuneka baqinisekise umgangatho, inombolo ye-UNS, umgangatho we-ASTM okanye we-EN, ubungakanani bebha, ukunyamezela, ukugqitywa komphezulu, i-EN 10204 3.1 MTC, ulawulo lwenombolo yobushushu, uvavanyo lwe-PMI, uvavanyo lwe-UT, ukuhlolwa kobukhulu kunye nokupakishwa kokuthumela ngaphandle. Umthengisi oqeqeshiweyo wensimbi engagqwali kufuneka ancede abathengi bathelekise ukumelana nokugqwala, amandla kunye neendleko ngaphambi kokukhetha ibha yentsimbi engagqwali ye-2205 okanye ibha yentsimbi engagqwali ye-316L.
