الوصف
أنبوب عائم is engineered for offshore oil/gas transportation, seawater intake, and floating platform systems. Manufactured from corrosion-resistant alloys (typically API 5L X65/X70, Duplex 2205) through precision UOE/JCOE forming and submerged arc welding (SAWL/SAWH), it integrates buoyancy modules and anti-biofouling coatings to ensure 25+ years of service in high-salinity and dynamic marine environments. Designed for deep-water installation and high-pressure containment, it excels in FPSO operations, subsea pipelines, and ocean thermal energy conversion projects.
