1. Yintoni intsimbi engagqwaliyo? Yintoni intsimbi engagqwaliyo ephindwe kabini?
Intsimbi engagqwaliyo ligama eliqhelekileyo lohlobo lwentsimbi engagqwaliyo, kwaye iintlobo zayo zahlulwe ngokusekwe kwisakhiwo esincinci. Eziqhelekileyo ziquka intsimbi engagqwaliyo ye-austenitic (efana ne-304, 316) kunye nentsimbi engagqwali ye-ferritic. Intsimbi engagqwaliyo ye-duplex luhlobo olukhethekileyo olunesakhiwo esincinci esingumxube wesiqingatha se-ferrite kunye ne-austenite.

2. Ziziphi iingenelo eziphambili zentsimbi engagqwali ye-duplex?
(1)Amandla aphezulu kakhulu:Amandla ayo okuvelisa aphindwe kabini kunentsimbi eqhelekileyo engenasici e-austenitic, oko kuthetha ukuba kwizicelo ezifana neebhafu zoxinzelelo, izinto ezincinci zingasetyenziselwa ukuhlangabezana neemfuno zamandla kunye nokunciphisa ubunzima kunye neendleko.
(2)Ukumelana kakuhle nokugqwala koxinzelelo (SCC):Kwindawo equlethe ii-ion ze-chlorine, intsimbi eqhelekileyo ye-austenitic stainless steel (efana ne-304) ithambekele kakhulu ekuqhekekeni kwe-corrosion, ngelixa intsimbi ye-duplex stainless steel ineengenelo zendalo kule nkalo, kwaye ukusebenza kwayo kungcono kakhulu kunokwentsimbi ye-austenitic ye-300 series.
3. Ngaba zikhonaNgaba kukho naziphi na izithintelo zentsimbi engagqwaliyo ezimbini?
(1) Ubushushu bokusetyenziswa bulinganiselwe:Ngenxa yendawo yayo yokuthamba kobushushu obuphakathi efana “nokuthamba kobushushu obuyi-475°C”, ayikhuthazwa ukuba isetyenziswe ixesha elide kwiindawo ezinobushushu obuphezulu obungaphezulu kwama-250°C-300°C;
(2) Iimfuno ezingqongqo zokucubungula kunye nokuwelda:Isiphumo sayo sokuqina komsebenzi obandayo sikhulu, i-plasticity kunye nokuqina kwayo kuphantsi kune-austenitic stainless steel, kwaye ukwakheka kwayo kunzima. Amandla omgca kunye nesantya sokupholisa kufuneka kulawulwe ngokungqongqo ngexesha lokudityaniswa ukuze kuthintelwe ukuna kwezigaba eziyingozi kunye nokutshabalalisa ibhalansi yala manqanaba mabini.
4. Ungakhetha njani phakathi kwezi zimbini?
Ukuba imeko yesicelo ineemfuno eziphezulu zamandla kwaye ijongene nomngcipheko wokugqwala koxinzelelo lwe-chloride (njengobunjineli baselwandle, izixhobo zeekhemikhali), intsimbi engagqwaliyo ye-duplex lukhetho olungcono;
Ukuba inkonzo ibandakanya amaqondo obushushu aphezulu okanye ifuna ukwakheka okubandayo okuntsonkothileyo, intsimbi engagqwaliyo ye-austenitic inokuba yeyona ifanelekileyo.
Ngamafutshane, intsimbi engagqwaliyo kunye nentsimbi engagqwaliyo ezimbini nganye ineenzuzo zayo, kwaye isitshixo sokukhetha sikukufanisa ngokuchanekileyo ubushushu, uxinzelelo kunye nendawo egqwaliyo yeemeko zokusebenza. Wamkelekile ukubonisana nathi.Tianjin Tanggu Water-Seal Valve Co., Ltd.Siziingcali kwimveliso yeiivalvu zebhabhathane, iivalvu zesango, iivalvu zokujongakunye nezinye iimveliso ezilandelelanayo. Singabala ngokuchanekileyo iskimu sezinto zepleyiti yevalvu efanelekileyo ngokweemeko zakho zokusebenza ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwevalvu.
