Cov ntawv thov tseem ceeb
Roj & Roj Kev Lag Luam
Qhov zoo tshaj plaws rau cov hlab ntsha siab, hnyav- cov kav dej ua haujlwm, thiab cov khoom siv ua haujlwm / khaws cia ua haujlwm siab -kub kua thiab gases-tshwj xeeb yog cov roj qaub nrog hydrogen sulfide- tiv thaiv sulfide kev nyuaj siab tawg hauv qhov hnyav downhole thiab refinery tej yam kev mob.
Petrochemical cog
Ib qho kev xaiv zoo tshaj plaws rau fabricating reactors, heat exchangers, thiab kaw lub tank, xa cov kev ua haujlwm ruaj khov thaum muaj kev kub ntxhov siab - kub, siab - siab hydrocarbon ua cycles.
Lub zog tiam
Dav siv rau cov khoom tseem ceeb hauv boilers thiab siab - cov khoom siv thermal, nrog rau kev ua haujlwm siab thermal thiab tswj kev nkag mus rau ntev - lub sijhawm ua haujlwm tsis cuam tshuam.
Kev ua tshuaj lom neeg
Haum rau cov khoom siv tseem ceeb hauv corrosive, siab - qhov kub thiab txias ib puag ncig, muab cov qauv kev ruaj ntseg kom tiv taus acidic, alkaline, thiab oxidizing tshuaj lom neeg.
Vim li cas thiaj xaiv peb:
Koj tuaj yeem tau txais cov khoom zoo meej raws li qhov koj xav tau ntawm tus nqi tsawg kawg nkaus.
Peb kuj muab Reworks, FOB, CFR, CIF, thiab qhov rooj rau qhov rooj tus nqi xa khoom. Peb xav kom koj ua deal rau shipping uas yuav zoo heev.
Cov ntaub ntawv uas peb muab yog muaj tseeb tiag, txoj cai los ntawm raw cov ntaub ntawv xeem daim ntawv pov thawj mus rau qhov kawg dimensional nqe lus.
Peb lav muab cov lus teb tsis pub dhau 24 teev (feem ntau hauv tib lub sijhawm)
Koj tuaj yeem tau txais cov khoom hloov pauv, zeb xa khoom nrog txo lub sijhawm tsim khoom.
Peb tau mob siab rau peb cov neeg siv khoom. Yog tias nws yuav tsis tuaj yeem ua tau raws li koj cov kev xav tau tom qab kuaj xyuas tag nrho cov kev xaiv, peb yuav tsis ntxias koj los ntawm kev cog lus tsis tseeb uas yuav tsim kev sib raug zoo rau cov neeg siv khoom.
