Duplex 2205 Kav cov khoom lag luam zoo hauv Suav teb
Piv rau cov roj uas tsis muaj roj, cov kav hlau ob lav tau lav tau ntau dua rau kev pitting thiab kev ntxhov siab corrosion tawg. Lub caij no, peb ASTM A 789 \ / A 790 kav dej thiab cov raj muaj nyob rau ntau qhov sib txawv, gaugeses raws li cov neeg siv khoom lag luam.
Lub Flange yog qhov thib ob feem ntau siv koom nrog txoj kev tom qab selding. Kev siv flanges tau siv thaum cov pob qij txha xav tau dismantling. Nws muab kev hloov tau rau kev saib xyuas. Flange txuas cov yeeb nkab nrog ntau yam khoom siv thiab li qub. Breakup Flanges tau ntxiv rau hauv cov raj xa hluav taws yog tias kev saib xyuas tsis tu ncua thaum lub sijhawm cog ntoo.
Ib Flange yog ib qho kev tawm tsam, daim di ncauj lossis sab nraud, tog twg los sab nraud lossis sab hauv, uas yog cov nqaj hlau xws li ib tug t-nqaj); Rau cov ntawv yooj yim tau yooj yim \ / hloov ntawm kev sib cuag nrog lwm yam khoom (raws li flange thaum kawg ntawm cov yeeb nkab, chav dej lub tog raj kheej, lossis ntawm lub ntsej muag lub koob yees duab); Los yog rau kev ruaj khov thiab taw qhia kev txav ntawm lub tshuab lossis nws cov ntu (raws li sab hauv flange ntawm tsheb ciav hlau lossis lub log los ntawm kev khiav tawm ntawm cov ciav hlau). Lo lus "Flange" kuj yog siv rau hom cuab yeej siv los ua cov flanges.
Duplex cov kav hlau stainless hlau feem ntau tsis kim dua vim tias cov khoom qis dua los ntawm cov khoom siv ntawm cov hlau uas tsis muaj roj. Piv nrog usteneric stainless hlau, duplex stainless hlau muaj zog ntxiv dag zog, yog li cov neeg siv tuaj yeem yuav cov yeeb nkab duplex thiab duplex yeeb nkab fittings nyob rau hauv qis thickness.
Nyob rau ntawm qhov kub no, ob tus hlau steel flanges tshaj 300 degrees Celsius tseem muaj kev tiv thaiv los ntawm kev sawv los ntawm kev xeb vim tias corrosion. Ciav muaj peev xwm kuj tau zoo heev thaum kub tsawg. Fabrication yog ua tiav tsuas yog nrog cov cuab yeej muab rau cov khoom siv hlau stainless. Yuav tsum tau huv kom zoo ua ntej siv. Qhov no yog ua los tiv thaiv cov hlau stainless los ntawm kev sib kis ntawm corroding hlau.
