Lub installation ntawm xws capping fittings ntawm cov yeeb nkab kom ntseeg tau tias muaj kev nyab xeeb ntawm cov yeeb nkab. Peb muab 1-8 x 6 hli hom 316L stainless hlau yeeb nkab haum.

Ntau tshaj 20 xyoo tsim khoom brass pluas dej phwj dej

S31803 yog cov qauv sau ua ke (tsis ua haujlwm) rau thawj lub duplex stainless hlau stainless. Cov txheej txheem tsis zoo tau tsim los ntawm cov pab pawg ua lag luam hauv xyoo 1970 los txo kev tsis meej pem thaum tib almoy tau hu ua ntau yam sib txawv, thiab hloov ua lwm yam. Txhua tus hlau yog sawv cev los ntawm ib tsab ntawv ua raws li tsib tus lej, qhov twg tsab ntawv sawv cev ntawm cov hlau series, i.E. s rau stainless hlau.

Txhawm rau kom xa cov raj xa dej, nws yog ib qho tsim nyog los tshem cov hose ncaj hauv cov raj xa dej. Thaum siv ntau lub raj xa dej, ntau yam kav dej yuav tsum tau siv. Thaum twg cov raj xa dej siv, lub luj tshib yuav tsum tau siv los hloov qhov loj ntawm cov raj xa dej. Thaum bifurcating, peb-txoj kev xaim cov flange kev sib txuas siv thaum lub raj xa hluav taws xob thiab kev sib txuas txias thiab kev sib tw txias thiab kev sib koom ua ke txias. , Hauv kev sib txuas ntawm ntau cov twj paj nruag, kuj tseem muaj cov txuas txuas thiab ntsaws ntawm cov twj paj nruag theem.

Qhov theem no ob theem hlau hlau pob hauv qab nyob rau hauv ib puag ncig uas ua rau muaj kev pib ua ntej nres ntawm cov qib tsis muaj Austenitic. Cov txheej txheem me me no tseem tiv thaiv kev tiv thaiv chloride ib puag ncig thiab muab kev tiv thaiv sulfide kev ntxhov siab corrosion.
