Qhov saum npoo ntawm cov yeeb nkab steel yog lub npe hu ua ib puag ncig uas qhov no yog los ntawm cov yeeb nkab steel txheej nrog cov rwb thaiv tsev nyob ib puag ncig, cov yeeb nkab saum npoo yog txawv ntawm plaub lub lis piam ntawm cov av.Yog li cov yeeb nkab los tiv thaiv corrosion txheej yog ib qho tseem ceeb thaiv kev tiv thaiv av yaig.Ib tus kws tshaj lij txawv teb chaws uas paub zoo tau muab tso rau pem hauv ntej "3PE france tiv thaiv txheej", kom deb li deb, txoj kev tiv thaiv corrosion yog dav siv.

Basic functions ntawm erw yeeb nkab txheej:

1, ua rau saum npoo ntawmERW steel kav dawb los ntawm electrochemical corrosion ntawm av nruab nrab, lub hauv paus physics ntawm cov kab mob corrosion tiv thaiv.

2, tiv thaiv kev txav ntawm cov av nruab nrab creep kev nyuaj siab, zoo li qub kev ntxhov siab thiab kev puas tsuaj quab yuam txoj kev thiab cov qauv ntawm cov txheej txheem kev tiv thaiv tshuab.

Lub hauv paus ntsiab lus ntawm lub nroog gas pipeline txheej xaiv:

a, zoo insulating thiab mechanical zog;

b, zoo tiv thaiv cathodic disbondment kev ua tau zoo;

c, zoo tiv thaiv dej, roj permeability;

d, zoo tshuaj tiv thaiv soaking kev ua tau zoo thiab anti-aging zog;

e, tsis kam mus rau qhov kub thiab txias kev ua haujlwm siab;

f, yooj yim kho thiab kho;

g, ntawm tus nqi tsim nyog.
