Cov ntawv thov tseem ceeb:
Cov nkoj siab:Tank rau roj, roj, petrochemicals, thiab tshuaj, siv nyob rau hauv refineries, ua cov nroj tsuag, thiab offshore platforms qhov twg lub zog thiab kev cia siab nyob rau hauv lub siab yog qhov tseem ceeb.
Boilers & Fais Fab Tsim: Cov khoom xyaw rau cov chav boilers thiab cov reactors, qhov uas tsis kam mus rau kub kub thiab thermal cycling yuav tsum tau ua haujlwm ntev -.
Cia Tank:Cov tso tsheb hlau luam loj rau cov kua thiab cov pa roj (API 650/620), muab kev ua haujlwm ruaj khov rau khaws cia cov roj av, cov khoom ua kom zoo, thiab cov khoom siv tshuaj.
Khoom siv:Thaum tshav kub kub exchangers, kav dej, thiab cov khoom siv, muaj nuj nqis rau nws cov weldability thiab toughness nyob rau hauv hnyav-duty ua tshuab.
Kev thauj mus los:Cov tsheb ciav hlau, tsheb thav duab, thiab cov khoom siv tsheb, muab cov kav ntev uas xav tau rau kev xav tau kev thauj mus los ib puag ncig.
Kev tsim kho:Cov choj, cov tsev, thiab cov qauv teeb pom kev zoo, siv qhov chaw muaj zog thiab kev siv nyiaj txiag tseem ceeb.
Cryogenic Applications:Cov cuab yeej siv rau qhov ntsuas kub qis xws li LNG, ua tsaug rau nws lub peev xwm los tuav lub zog ntawm qhov txias heev.
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.
