904L steel stainless exchanger ubushushu obonisiwe Umfanekiso

904L intsimbi yokutshintshiselana kobushushu

Inkcazelo emfutshane:

I-Stainless Steel 904L iTubes yokuTshintsha ubushushu obungenamthungo, i-904L i-Stainless Steel Exchanger Exchanger Tubing, i-ASTM A249 904L i-Stainless Steel engenamthungo yoTshintshiselwano lwe-Heat Tubing, i-SS 1.4539 ye-Heat Exchanger Tube, i-Stainless Steel 904L ye-Heat Exchanger Tube.

I-Stainless Steel 904L yi-SS ye-austenitic enokongezwa kancinane kwe-molybdenum enika ukuxhathisa okulungileyo kwi-corrosion, ukuxhathisa kwi-crevice corrosion, kunye nokuchasana kwe-pitting kwindawo ye-chloride.Ibakala libonisa ukuxhathisa okulungileyo ekunciphiseni i-asidi kunye namandla aphezulu kwiqondo lokushisa eliphezulu.Ukongezwa kobhedu kwibakala kubonisa ipropathi egqwesileyo exhathisayo kuyo yonke indawo eneasidi egxininisiweyo ngokubanzi iiasidi zesulfuric.Ubukho bomxholo we-alloy ephezulu kwibakala ibonelela ngoxhathiso olulungileyo loxinzelelo lwe-crack corrosion kwaye ke nebakala liyachaphazeleka.

Ulwazi olusisiseko

I-SS 904L ngumxholo ophantsi wekhabhoni oqinisekisa ukuxhathisa ukuvakalelwa ngenkqubo ye-welding kwaye inceda ekukhuseleni i-intergranular corrosion.Iityhubhu zokutshintsha ubushushu beli bakala zithandwa kakhulu phakathi kwabathengi ngenxa yeempawu zayo ezinkulu.

umgangatho ophezulu weStainless Steel 904L yeeTubhu zokuTshintsha ubushushu kubathengi bazo kwihlabathi liphela.Ishishini lide lafikelela kwindawo ephezulu kwimarike ngenxa yeminyaka yabo yokusebenza nzima kunye namava.Abathengi banikezelwa ngomgangatho ophezulu wetyhubhu yokutshintsha ubushushu ngexabiso elikhuphisana kakhulu.Izinto ezingasetyenziswanga ezisetyenziswa ngabo zithengwa kubathengisi bemarike abathembekileyo abaphinda bavavanywe umgangatho ngabasebenzi boshishino.Bakwabonelela ngeempawu ezizodwa kwiimveliso zabo ezenziweyo.Iimpawu ezikhethekileyo ezifana nokugqiba okuphezulu, imilinganiselo echanekileyo, ukuqina okulungileyo kunye nokuhanjiswa kwexesha lemveliso zezinye zeenkonzo.
