Natural gas yog ib qho huv, siv tau, yooj yim thiab zoo zog thiab cov khoom siv tshuaj lom neeg.Nws txoj kev siv thiab siv tau muaj txiaj ntsig tseem ceeb ntawm kev lag luam, kev sib raug zoo thiab ib puag ncig.Nrog rau kev txhim kho ntxiv ntawm Tuam Tshoj cov pa roj carbon monoxide, kev lag luam roj av yuav ntsib nrog cov cib fim tshiab, kuj tseem ntsib cov teeb meem tshiab.Kev hloov pauv ntawm thawj cov yeeb nkab network lossis tso cov yeeb nkab tshiab yuav tsum hais txog kev nyab xeeb, tshem tawm tag nrho cov kev pheej hmoo.Raws li tuaj yeem pom los ntawm cov yeeb nkab network hauv tsev thiab txawv teb chaws, qhov ua rau muaj kev sib tsoo, tshwm sim los ntawm tus txiv neej txoj kev puas tsuaj raug suav nrog kev puas tsuaj rau cov kav dej (nrog rau kev ntxhov siab corrosion tawg) rau qhov thib ob.Cov yav tas yog feem ntau nyuaj los xyuas, feem ntau overlooked, pipeline corrosion undoubtedly cov txheej txheem tseem ceeb yuav tsum tau hais.

High anticorrosion txheej daim ntawv thov
Lub hauv paus ntsiab lus ntawm domestic thiab thoob ntiaj teb underground natural gas pipeline corrosion yog tsim nyog raws li cov kav dej ntawm thaj chaw struts, topography, geological tej yam kev mob, npog supplemented los ntawm cathodic tiv thaiv.Cov xim siv: roj av asphalt, thee tar enamel, epoxy xim.Hauv tsev faus kav dej los tiv thaiv corrosion feem ntau siv roj av asphalt xim.Yog hais tias cov av ib puag ncig, microbial, tsis muaj kev cuam tshuam loj heev nrog cov nroj tsuag sib sib zog nqus, suav tias yog ib qho pheej yig los tiv thaiv txheej txheej.Nws cov khoom ntws tsis haum rau qhov kub thiab txias ib puag ncig thiab muaj kuab paug loj ntawm ib puag ncig thaum tsim kho, nws siv tau qhia txog kev poob qis.Los ntawm kev xav thoob ntiaj teb, feem ntau siv thaum thawb thee tar enamel thiab epoxy xim.Cov qub muaj zog tiv thaiv microbial corrosion, tiv thaiv cov nroj tsuag hauv paus nkag mus, tsis tshua muaj dej nqus, tsis kam mus rau cathodic delamination, kev sib raug zoo qhwv cov khoom muaj zog rau ntawm phab ntsa, muaj qhov pom tseeb zoo rau kev siv hauv cov roj thiab cov kav dej hauv Tebchaws Meskas, Russia. , hauv kev siv loj.

Pipeline txheej txheej pem hauv ntej nto pretreatment kev txhim kho
Lub preservative zoo nyob ntawm theem ntawm coated pem hauv ntej nto pretreatment txoj kev xaiv.Cov tsoos degreasing xeb Txoj Cai ntawm lub sijhawm thiab kev ua haujlwm muaj kuab paug yog qhov nyuaj rau kev lav zoo.Nyob rau hauv xyoo tsis ntev los no tus nyiam siv kub unglazed txoj cai degreasing, cov yeeb nkab loading rau hauv tshwj xeeb rauv ntawm 350 ~ 400 ℃ supplemented nrog cua, rwb thaiv tsev 3 ~ 4 h, cov roj hlawv lav degreasing zoo.Peening machinery es tsis txhob ntawm cov tsoos txoj kev ntawm pickling.Txoj kev no yog siv cov huab cua compressed los nqa cov hlau txhaj tshuaj (los yog xuab zeb) los tsim kom muaj kev kub ceev ntawm kev thauj khoom muaj zog cuam tshuam rau cov hlau nto los ntawm lub nozzle ntawm rab phom kom tshem tawm cov roj lossis oxide.Nws xeb tag nrho, tab sis kuj txhim kho qhov roughness ntawm qhov chaw, kom qhov chaw sib cuag ntawm phab ntsa thiab txheej txheej (kwv yees li 20 zaug), thiab txhawm rau txhim kho cov txheej txheem sib zog, tuaj yeem tiv thaiv kev sib sib zog nqus delamination.
