Cov yeeb nkab steel no muaj kev tiv thaiv corrosion zoo heev thiab siv dav hauv roj av, tshuaj lom neeg kev lag luam, roj av, kev tsim kho thiab lwm yam.
Nws yog tsim los ntawm peb txheej: thawj txheej yog high-density polyethylene, txheej thib ob yog txheej nplaum, thiab txheej thib peb yog txheej txheej polyethylene los tiv thaiv corrosion. Ntawm lawv, polyethylene yog cov khoom siv polymer nrog cov tshuaj zoo corrosion kuj thiab drilling tsis kam, uas tuaj yeem tiv thaiv cov kav hlau tsis zoo los ntawm qhov chaw sab nraud. Nyob rau tib lub sijhawm, cov nplaum txheej tuaj yeem muab cov adhesion zoo ntawm cov khaubncaws sab nraud povtseg ntawm cov khoom sib txawv thiab txhim kho tag nrho lub zog ntawm cov yeeb nkab steel. Qhov tsim nyog ua ke ntawm peb txheej txheej saum toj no tso cai rau 3pe spiral steel yeeb nkab yuav luag tag nrho cov kev tsis txaus ntawm cov kav hlau zoo tib yam.
3pe kauv steel yeeb nkab kuj muaj kev cuam tshuam zoo heev thiab kev ua haujlwm kub. Txawm nyob rau hauv qhov kub thiab txias ib puag ncig, 3pe kauv steel kav tuaj yeem tswj kev ua haujlwm ruaj khov, ua kom muaj kev nyab xeeb mus ntev.
Ua ntej siv 3pe kauv steel yeeb nkab, yuav tsum tau ua cov kev npaj ua ntej. Ua ntej tshaj plaws, qhov saum npoo ntawm cov yeeb nkab steel yuav tsum tau kho ua ntej los ntxuav nws thiab xyuas kom meej tias nws tsis muaj roj, plua plav thiab lwm yam impurities. Tom qab ntawd, primer kev kho mob yuav tsum tau siv primer los ua kom cov corrosion kuj ntawm steel yeeb nkab. Thaum kawg, nruab nrab-txheej txheej thiab txheej txheej saum toj kawg nkaus tau ua tiav los ua tag nrho 3pe txheej tiv thaiv corrosion, ua rau cov yeeb nkab steel muaj kev tiv thaiv corrosion zoo dua.
