Anti-corrosion steel kav ua si tseem ceeb thiab sib txawv hauv tib neeg lub neej txhua hnub. Anti-corrosion steel kav feem ntau xa mus rau kev siv cov txheej txheem tshwj xeeb los tiv thaiv kev xeb ntawm cov kav hlau zoo tib yam (xws li cov kav dej seamless, welded kav), kom cov kav hlau muaj qee yam kev tiv thaiv corrosion. Corrosion peev xwm feem ntau yog siv rau cov dej tsis zoo, tiv thaiv xeb, tiv thaiv acid thiab alkali, tiv thaiv oxidation thiab lwm yam ntxwv. Feem ntau hais lus, PE anti-corrosion steel yeeb nkab yog hais txog polyethylene anti-corrosion steel yeeb nkab, uas yog cov kab lus tubular ua tiav los ntawm kev tshawb fawb thiab thev naus laus zis. PE anti-corrosion steel kav yog dav siv nyob rau hauv roj, natural gas, lub nroog gas, lub nroog dej, thee-dej slurry pipelines, thiab lwm yam.

Kev ntsuas los tiv thaiv corrosion kuj tseem tuaj yeem ua rau sab hauv thiab sab nrauv ntawm cov kav hlau steel raws li qhov xav tau sib txawv. Cov feem ntau yog epoxy thee tar pitch anti-corrosion steel kav, polyurethane txheej los tiv thaiv corrosion, cement mortar anti-corrosion nyob rau sab hauv phab ntsa ntawm anti-corrosion steel kav, thiab lwm yam. Anti-corrosion steel kav yog tsuas yog siv nyob rau hauv tshwj xeeb yuav tsum tau los yog Engineering teb nyob rau hauv ib puag ncig hnyav.

Anti-corrosion steel yeeb nkab yog hais txog cov kav hlau uas tau ua tiav los ntawm kev siv tshuab los tiv thaiv corrosion, uas tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam los ntawm kev cuam tshuam los ntawm cov tshuaj lom neeg los yog electrochemical thaum thauj thiab siv. Raws li cov ntaub ntawv txheeb cais ntawm peb lub teb chaws, kev lag luam ncaj qha poob ntawm cov yeeb nkab steel hauv tsev yog ntau tshaj 280 billion yuan txhua xyoo, thiab lub ntiaj teb txhua xyoo poob vim steel yeeb nkab corrosion yog siab li 500 billion US dollars. Anti-corrosion steel kav tuaj yeem tiv thaiv kom tsis txhob muaj corrosion, ua kom lub neej ntev ntawm cov kav dej steel, thiab txo cov nqi khiav haujlwm ntawm cov kav hlau. Cov yam ntxwv ntawm kev tiv thaiv corrosion steel kav yog corrosion kuj, tsis muaj to, siab toughness, zoo heev yooj, zoo tiv thaiv khawb, thiab zoo tiv thaiv kom ceev nrooj kis. Nyob rau hauv ib qho, kev pab cuam lub neej ntawm cov kav dej los tiv thaiv corrosion yog ntau dua lossis sib npaug rau hauv ib puag ncig ntawm 60 degrees Celsius, nws tuaj yeem muaj lub neej ntev ntawm ntau tshaj 50 xyoo.

Ntxiv nrog rau kev txhim kho lub neej kev pab cuam ntawm cov kav hlau steel los ntawm kev tiv thaiv corrosion, nws kuj tau tshwm sim hauv cov hauv qab no:

1. Kev sib xyaw ua ke ntawm cov khoom siv dag zog ntawm cov yeeb nkab steel thiab corrosion kuj ntawm cov yas.
2. Cov txheej txheej phab ntsa yog ntau tshaj 2.5mm, uas yog khawb-resistant thiab pob-resistant.
3. Kev sib txhuam coefficient ntawm sab hauv phab ntsa yog me me, 0.0081-0.091, uas txo kev siv zog.
4. Sab hauv phab ntsa yog du thiab tsis yooj yim rau nplai, thiab muaj kev ua haujlwm ntawm kev tu tus kheej.
