Yuav ua li cas xaiv phaj thiab gasket ntawm phaj kub exchanger

Ntxiv nrog rau cov dej, Feem ntau ntawm cov xov xwm uas siv hauv phaj kub exchanger yog cov tshuaj ntshiv, cov tshuaj nplua nuj, sodium hydroxide, sulfuric acid thiab lwm yam tshuaj lom neeg, uas yooj yim ua rau corrosion ntawm phaj thiab o thiab kev laus ntawm gasket.

Phaj thiab gasket yog cov ntsiab lus tseem ceeb ntawm phaj kub exchanger, Yog li xaiv cov phaj thiab cov khoom siv gasket yog qhov tseem ceeb tshwj xeeb.

Phaj khoom xaiv ntawm phaj kub exchanger:

Cov dej huv huv, dej ntws, cov roj siv tau, cov roj ntxhia thiab lwm yam xov xwm stainless hlau (AISI 304, AISI 316, thiab lwm yam).
dej hiav txwv, brine, salinization thiab lwm yam xov xwm titanium thiab titanium palladium (Ti, Ti-Pd)
Dilute sulfuric acid, dilute sulfur ntsev aqueous tov, inorganic aqueous tov thiab lwm yam xov xwm 20Cr, 18Ni, 6Mo (254SMO) thiab lwm yam alloys
Kub kub thiab siab concentration caustic soda nruab nrab Ni
Concentrated sulfuric acid, hydrochloric acid thiab phosphoric acid nruab nrab Hastelloy alloy (C276, d205, B20)

Cov khoom xaiv ntawm gasket rau phaj kub exchanger:

Cov neeg feem coob paub tias cov roj hmab sealing gaskets feem ntau siv cov ntaub ntawv, xws li EPDM, nitrile roj hmab, hydrogenated nitrile roj hmab, fluororubber thiab lwm yam.

EPDM Kev pabcuam kub yog - 25 ~ 180 ℃. Nws yog tsim rau kua nruab nrab superheated dej, chav, atmospheric ozone, tsis muaj roj av raws li lubricating roj, qaug zog acid, tsis muaj zog puag, ketone, cawv, ester, thiab lwm yam.
NBR Kev pabcuam kub yog - 15 ~ 130 ℃. Nws yog tsim rau ntau yam khoom siv roj ntxhia xws li kua nruab nrab, roj teeb roj, lubricating roj, tsiaj thiab zaub roj, dej kub, dej ntsev, thiab lwm yam. 
HNBR Kev pabcuam kub yog - 15 ~ 160 ℃. Nws yog tsim rau cov kua nruab nrab kub-kub dej, roj crude, sulfur-muaj roj thiab organic sulfur-muaj cov tebchaw, ib co cua kub hloov roj, tshiab refrigerant R134a thiab ozone ib puag ncig.
FKM Kev pabcuam kub yog -15 ~ 200 ℃. Nws yog haum rau cov kua nruab nrab, xws li concentrated sulfuric acid, caustic soda, tshav kub hloov roj, cawv roj roj, acid roj roj, high-temperature chav, dej chlorine, phosphate, thiab lwm yam.
