Tus sawv cev ua tub rog: Haum rau cov ntawv thov nyob rau hauv high-kub seaterwater thiab lwm thaj av ua hnyav.

3. Monel (400, 500)

Khoom:

Zoo tshaj corrosion Kuj: Monel yog tshwj xeeb tiv taus corrosion hauv seawater, acids, thiab alkalis, ua qhov kev xaiv zoo rau cov kev siv marine.

Muaj zog thiab muaj sia: Tswj hwm nws lub zog txawm tias tsis muaj kev ntxhov siab thiab kub.

Zoo Weldability: Muaj cov weldability zoo, tso cai rau siv rau hauv cov kev cai tsim qauv.

Cov Ntawv Thov:

Tus sawv cev ua tub rog: Siv dav hauv nkoj, Offshore platforms, thiab cov ntawv thov tom qab.

Kev Lag Luam: Ua haujlwm hauv cov tshuaj txhoj puab heev, xws li cov uas pom hauv cov kua qaub thiab cov petrochemical.

Roj & Roj: Monel flanges tau siv hauv kev tshawb nrhiav roj thiab cov chaw ib puag ncig uas yuav tsum muaj siab tiv thaiv hydrogen sulfide thiab lwm cov neeg sawv cev.

4. Titanium (Qib 2, Qib 5)

Khoom:

Ntsej Muag Corrosion Kuj: Titanium yog qhov muaj zog tiv thaiv ntau yam ntawm cov tshuaj xeb, suav nrog cov tshuaj polrosive, suav nrog cov kab xeb, dej hiav txwv, thiab sulfuric acid.

Kev hnyav thiab muaj zog: Titanium muaj qhov piv rau lub zog zoo tshaj plaws, ua rau nws zoo tagnrho rau cov ntawv thov tsis tau ntxiv qhov hnyav.

Zoo heev Weldability: Titanium yog ib qho yooj yim rau Weld, tshwj xeeb tshaj yog thaum cov txuj ci tshwj xeeb yog siv kom tsis txhob muaj paug.

Cov Ntawv Thov:

Tus sawv cev ua tub rog: Siv rau cov flanges raug rau dej hiav txwv, xws li nyob rau hauv cov qauv nkoj thiab cov txheej txheem tawm tsam.

Kev Lag Luam: Ua haujlwm hauv reactors thiab cov hlab ntsha siv nyob rau hauv ib puag ncig uas koom nrog kev ua kom nruj thiab tshuaj lom neeg.

Ib tug tub rog: Lub teeb yuag, cov khoom siv siab ua kom ua rau titanium flanges tsim nyog rau Aerospace cov ntawv thov.

5. 254 SMO Stainless Hlau

Khoom:

Zoo heev corrosion: 254 Smo yog cov Austenitic Ausenitic Stainless Hlau, muab kev tshwj xeeb ua rau pitting, corrosion, tshwj xeeb hauv chloride ib puag ncig.

Siab Zog: Cov alloy no muaj lub zog loj piv rau cov qauv stainless hlau thiab khaws nws cov khoom hauv ob qho tib si txias thiab kub ua haujlwm.

Kuj yuav ntxhov siab corrosion tawg: 254 SmO tiv thaiv kev tawg hauv chloride ib puag ncig, ua rau nws zoo tagnrho rau kev siv nyob rau hauv kev txhoj puab heev.

Cov Ntawv Thov:

Kev Lag Luam: Qhov zoo tagnrho rau cov khoom siv siv tshuaj lom neeg thiab petrochemical uas muaj tshuaj corrosive xws li acids thiab chlorides tam sim no.
