I-2507 i-valve yensimbi engenasici ye-duplex isebenzisa i-JB/T7746 “I-Compactivalve yentsimbi” Intshayelelo esemgangathweni yoshishino
Inkampani yethu igxile ekuveliseni amanzi olwandle i-2205 duplex ivalve yensimbi engenastainless 2507 duplex stainless steel stainless valve 2205 duplex steel stainless globe valve 2507 duplex steel stainless globe valve 2205 duplex steel stainless gate ivalve 2507 stain steel duplex uhlobo lokucoca 2507 duplex intsimbi stainless filter 2205 itshekhi valve 2507 itshekhi valve kunye nezinye iimveliso
Amanzi olwandle 2205 duplex steel valve molybdenum duplex steel stainless inokumelana kakuhle nekloride stress corrosion phantsi koxinzelelo oluphantsi. Ngokuqhelekileyo, i-18-8 uhlobo lwe-austenitic stainless steel luvame ukuxinzelela ukuphuka kwe-corrosion kwisisombululo se-chloride engathathi hlangothi ngaphezu kwe-60C. Abatshintshi bobushushu, i-evaporators kunye nezinye izixhobo ezenziwe ngolu hlobo lwensimbi engenasici kwi-industry medium of trace chloride kunye ne-hydrogen sulfide banotyekelo lokuvelisa i-stress corrosion fracture, ngelixa i-duplex stainless steel inokumelana okulungileyo.
(2) Amanzi olwandle 2205 duplex valve yentsimbi molybdenum duplex steel stainless inokumelana umhlwa elungileyo. I-pitting ebalulekileyo ye-duplex steel stainless steel ifana ne-austenitic stainless steel kunye ne-pitting resistance efanayo (PRE = Cr% + 3.3Mo% + 16N%). I-corrosion resistance of duplex steel stainless kunye ne-austenitic stainless steel ifana ne-AI 316L. Ukuxhatshazwa kwe-corrosion ye-chromium duplex ephezulu yensimbi engenasici equkethe i-25% Cr, ngakumbi i-nitrogen, iphezulu kune-AI 316L.
(3) Ngokuchasana nokugqwesa okuhle kokudinwa kunye nokunxiba ukusebenza kwe-corrosion. Kwezinye iimeko ze-corrosive medium, zilungele ukuveliswa kweempompo, iivalve kunye nezinye izixhobo zamandla.
(4) Iipropati ezilungileyo ezibanzi zoomatshini. Amandla aphezulu kunye namandla okukhathala, amandla emveliso yi-18-8 uhlobo lwe-austenitic stainless steel 2 amaxesha. Kwimeko yesisombululo esiqinileyo, i-elongation ifikelela kwi-25%, kwaye ixabiso lokuqina i-AK (V-notch) lingaphezulu kwe-100J.

(6) Uluhlu lweqondo lokushisa olusebenzayo lwe-duplex yensimbi engenasici equkethe i-chromium ephantsi (i-18% Cr) ibanzi kune-18-8 yensimbi engenasici ye-austenitic, kwaye ukuxhathisa kuncinci. Inokuqengqeleka ngokuthe ngqo ukuvelisa ipleyiti yensimbi ngaphandle kokubumba. I-Duplex steel stainless ene-chromium ephezulu (25% Cr) inzima kancinci kune-austenitic steel stainless steel thermal processing, inokuveliswa ipleyiti, ityhubhu kunye neemveliso zocingo.
(7) ebandayo ukusebenza ngaphezu 18-8 uhlobo austenitic stainless steel stainless ukusebenza isiphumo lukhuni inkulu, kwi ityhubhu, ipleyiti deformation kwinqanaba lokuqala, kufuneka ifake uxinzelelo olukhulu deformation.
(8) Xa kuthelekiswa ne-austenitic stainless steel, i-conductivity ephezulu ye-thermal, i-coefficient yokwandisa i-linear ephantsi, ifanelekile kwi-lining yezixhobo kunye nokuveliswa kwepleyiti edibeneyo. Ikwafanelekile ukwenza i-tube core ye-heat exchanger, kwaye ukuhanjiswa kobushushu kuphezulu kunoko kwe-austenitic stainless steel.
9 Okuya kusezantsi komxholo wechromium we-duplex steel stainless, ukuncipha komonakalo wenqanaba elilinganayo le-brittle.
