Upstream - Hydrocarbon sau kab
Roj thiab roj header kab thauj cov roj lossis roj los ntawm thaj chaw tsim khoom mus rau qhov chaw cia lossis cov kav dej loj dua. Peb muab cov raj steel ntawm ntau qib thiab txoj kab uas hla rau kev tsim kho cov kab sau thiab tshuab. Peb cov raj yog zoo tagnrho rau corrosive ib puag ncig, siab thiab tsis kub, thiab siab.
