"Kwayt Group Launches "Deep Sea Star" Anti-corrosion Steel Pipe Series, Extending Service Life to 50 Years" Date : 2025/05/23

China-Qingdao-- In order to meet the challenges of corrosion protection in the development of offshore oil and gas and the construction of cross-sea bridges, the R&D Center of Kwayt Group has officially launched the 3PE+FBE double-layer anti-corrosion steel pipe. The anti-corrosion steel pipe adopts the composite technology of nano-sized epoxy powder coating and polypropylene reinforced tape, which improves the salt spray resistance by 400% compared with the traditional galvanized steel pipe.

Technical Highlights

Ultra-long life: Passed ASTM G85 salt spray test, guaranteeing 50 years of maintenance-free submarine pipeline.

Intelligent monitoring: optional embedded RFID chip, real-time transmission of pipe wall thickness data.

Green process: 95% recycling rate of production wastewater, EcoVadis Bronze rating.

Application Scenarios

Offshore wind power piling
Deepwater oil and gas transportation
Immersed tube tunnels for cross-sea bridges
