I-Duplex 2205 VS 316 iNsimbi eNgatyiwayo

I-316 insimbi engenasici yinto eqhelekileyo, esetyenziswa ngokubanzi kwi-petrochemical, izityalo zochumisa, ukwakha iinqanawa kunye namanye amashishini. Ukusetyenziswa kwe-duplex steel 2205 kuya kusanda ngakumbi, ngakumbi kwi-oyile engaselunxwemeni, ukukhutshwa kwetyuwa emanzini olwandle kunye namanye amasimi aneemfuno eziphezulu zokubola. Nokuba kusetyenziswe na316 umbhobho wentsimbiokanye umbhobho we-duplex yingxaki abathengi bethu bahlala bedibana nayo. Eli nqaku lazisa ngokufutshane umahluko phakathi kwe-duplex 2205 kunye ne-316 yensimbi engenasici. Ndiyathemba ukuba iya kuba luncedo kuwe.

Umahluko weMichiza phakathiDuplex 2205kunye ne-316 SS

I-316 insimbi engenasici isetyenziswa ngokubanzi kwishishini lemichiza ngenxa yokumelana nokugqwesa kwayo okugqwesileyo. Ine-2-3% ye-molybdenum element, kwaye iphuma kwi-derivative ye-18-8 ye-austenitic stainless steel. Ngokuphathelele i-Duplex 2205, yongezwe kunye nenitrogen ukuphucula ukuxhathisa kwayo kwi-corrosion. Kwaye isisombululo esiluqilima izicubu kwi-ferrite kunye ne-austenite iye yahlala kwisiqingatha ngasinye, ubuncinane omnye wabo uya kufikelela kwi-30%, eyenza ukuba yenze iimpawu ze-ferrite kunye ne-austenitic stainless steel.

Umahluko phakathi kwe-Duplex 2205 kunye ne-316 ye-Stainless Steel

• a) Amandla esivuno se-duplex 2205 lixesha elinye ngaphezulu kwe-316L, kwaye inokuqina okwaneleyo kweplastiki yokubumba. Kwaye ubukhulu bodonga lwesitya soxinzelelo olwenziwe nge-duplex 2205 yi-30-50% encinci kune-316L, enokugcina iindleko.

• b) I-Duplex 2205 iqhuba kakuhle kakhulu ekuxhathiseni ukuthotywa koxinzelelo, ngakumbi xa isetyenziswa kwimo engqongileyo yaselwandle equlethe ii-ion ze-chloride. Nangona kunjalo, i-corrosion yoxinzelelo yingxaki ebonakalayo yokusombulula i-austenitic stainless steel kubandakanya i-316L.

• c) I-Duplex 2205 yenza uxhathiso olungcono lwe-corrosion kune-316L yenza kwiindlela ezininzi. Yenza uxhathiso oluphezulu kakhulu lwe-acetic, i-asidi ye-formic, kwaye inokuba yindawo yentsimbi ye-austenitic, kunye ne-alloy resistant corrosion. Nangona kunjalo, ukukhetha i-duplex 2205 okanye i-316L, isagqitywa yimfuno yokusingqongileyo kunye neendleko.

• d) I-Duplex 2205 inamandla aphezulu kunye nokumelana ne-corrosion yendawo efanelekileyo, ukunxiba ukumelana ne-corrosion kunye nokusebenza kokukhathala kwe-corrosion, okungcono kune-316L yensimbi engenasici.

• e) I-coefficient yokwandiswa komgca we-duplex 2205 ingaphantsi kwe-316L, kwaye isondele kwi-carbon steel. Oku kwenza ukuba i-duplex 2205 ilungele ukudityaniswa kwentsimbi ye-carbon, izisa ukubaluleka okukhulu kubunjineli.

• f) Nokuba iphantsi kweemeko zomthwalo oguqukayo okanye omileyo, i-duplex 2205 inomthamo ophezulu wokufunxa amandla kune-316L, ezisa iingenelo ezicacileyo kunye nexabiso elisebenzayo lesicelo seendawo zesakhiwo okanye imibhobho xa ijongene neemeko zikaxakeka ezifana neempembelelo, ugqabhuko-dubulo.

Ububi beDuplex 2205

Ngeenzuzo ezininzi, i-duplex 2205 ibonakala ingaphezulu kune-316. Nangona kunjalo, xa kuthelekiswa no-316, i-duplex 2205 nayo ineziphene:

• a) Ukusetyenziswa kwe-duplex 2205 ayikho jikelele okanye iyantlukwano njenge-316L. Ngokomzekelo, ukuba umntu ufuna ukusebenza phantsi kweqondo lokushisa elingaphantsi kwama-degrees angama-250 ixesha elide, ngoko kuphela i-316L yensimbi engenasici inokuba nobuchule.

• b) Ukuqina kweplastiki ye-duplex 2205 ihlwempuzekile kune-316L, kwaye iphinda isebenze kakubi ekusetyenzweni nasekuyikeni.

• c) I-Duplex 2205 ine-brittleness yobushushu obuphakathi, kwaye unyango lobushushu kunye nenkqubo ye-welding kufuneka ilawulwe ngokungqongqo, ukwenzela ukuba kuthintelwe isigaba esiyingozi ukuba sibonakale, sibangele umonakalo.

• d) Xa kuthelekiswa ne-austenitic stainless steel, ubuthathaka be-duplex yensimbi engenasici kukuba iqulethe isixa esikhulu se-ferrite tissue.

I-Duplex 2205 VS 316 SS Iindleko

Abanye abantu banokucinga ukuba ixabiso le-duplex steel liphezulu kakhulu, liphezulu kakhulu kune-316 insimbi engenasici. Enyanisweni, kuxhomekeke kwimveliso.

Sinikezela zombini i-duplex 2205 kunye ne-316 SS umbhobho kunye nokufakelwa, wamkelekile ukuba uqhagamshelane nathi ukuba kukho naziphi na iimfuno.
