Koj puas tuaj yeem siv galvanized yeeb nkab rau roj?
Tsis yog, vim qhov no ua rau muaj kev pheej hmoo ntawm electrolytic corrosion ntawm cov hlau sib txawv.
Cov yeeb nkab zoo li cas yog siv rau cov kav dej roj?
API Carbon Steel Yeeb Nkab
API Carbon Steel Yeeb Nkab, nrog rau lawv cov kev ua tau zoo thiab lub zog tensile, yog qhov zoo tshaj plaws rau kev thauj cov roj thiab roj hauv cov chaw refineries lossis rau cov neeg siv khoom kawg. Qib ntsuas qhov feem pua ntawm cov pa roj carbon - los ntawm qis mus rau siab carbon steel - cuam tshuam qhov yooj thiab hardness.
Hom yeeb nkab twg tuaj yeem galvanized?
Ntau qib sib txawv ntawm cov hlau tuaj yeem ua galvanized. A53 steel yeeb nkab thiab A595 steel yeeb nkab yog ob ntawm cov qib feem ntau. Tab siscam khwb cia hlau, kub- dov steel, txias- dov steel, thiab txawm tias qee qib stainless hlautxhua yam tsim nyog rau galvanization.
Dab tsi yog galvanized yeeb nkab siv rau?
Galvanized kav yog cov kav hlau uas tau dipped rau hauv ib qho kev tiv thaiv zinc txheej rautiv thaiv corrosion thiab xeb. Galvanized piping feem ntau ntsia hauv tsev ua ntej xyoo 1960. Thaum nws tau tsim, galvanized yeeb nkab yog lwm txoj hauv kev rau cov kav dej rau cov kav dej.
Dab tsi yog qhov sib txawv ntawm cov yeeb nkab roj thiab roj yeeb nkab?
Cov kav dej yog feem ntau tiv taus corrosion dua li cov kav dej rojvim muaj ntau yam cuam tshuam txog qhov xwm txheej ntawm cov khoom thauj. Firstly, natural gas muaj tsawg impurities tshaj roj. Qhov no txhais tau hais tias nws tsis tshua muaj kev cuam tshuam nrog cov khoom siv yeeb nkab thiab ua rau corrosion dhau sijhawm.
