4. Offshore Pressure Vessels
Kub-Kev Muag Khoom: Corrosion resistance (tsis muaj impurities) thiab qis -kub kev ua tau zoo haum offshore platforms thiab FPSOs.
5. Chemical Intermediate Storage Tanks
Kub-Kev Muag Khoom: Resistant corrosive media (methanol, ethylene glycol) thiab kev kub siab, txhawb kev cog qoob loo.
GNEE's Kub-Muag ASME SA612 Hlau Phaj Qhov Zoo
Raws li tus neeg muag khoom ntseeg siab ntawm SA612, GNEE sawv tawm hauv qhov kub - muag kev lag luam nrog 4 lub zog tseem ceeb:
1. Zoo Guaranteed & Certified
ASME Tshooj VIII tau pom zoo, EN 10204 3.2 tau ntawv pov thawj, thiab tag nrho traceability ntawm smelting mus rau kev xa khoom.
Hauv -lub tsev kuaj sim ua qhov tensile, cuam tshuam, thiab tshuaj ntsuam xyuas rau txhua pawg- kom ntseeg tau qhov sib xws.
2. Kev hloov kho yooj yim & xa khoom sai
Kub-muag specs (12mm-50mm) hauv Tshuag; kev cai thicknesses (6mm-100mm) thiab qhov ntev muaj.
Kev sib koom tes thoob ntiaj teb kev sib koom tes (Maersk, COSCO) kom paub meej txog - lub sijhawm xa mus rau cov chaw nres nkoj loj thoob ntiaj teb.
3. Tus nqi -Tus nqi zoo
Tus nqi ntawm lub Hoobkas ncaj qha (tsis muaj tus neeg nruab nrab) rau kub- muag khoom; bulk xaj luv nqi muaj.
Kev txhawb nqa tsim qauv hnyav (ntawm pab pawg kws tshaj lij) pab txo cov nqi khoom siv tag nrho.
4. Ua tiav Tom qab-Kev Pabcuam Muag
Kev cob qhia cov txheej txheem vuam (raws li ASME IX) thiab kev thov kev sab laj.
1-xyoo lav zoo rau kev tsim khoom tsis raug.
