LSAW Pipe DN900 ASTM A252 GR.2 For Marine And Bridge Piling

Huayang Steel Pipe leverages two high-end longitudinal submerged arc welding (LSAW) production lines to manufacture DN900 ASTM A252 Grade 2 pipes specifically optimized for the rigors of heavy-duty piling. Our DN900 piles feature a robust 35,000 psi minimum yield strength, providing the necessary axial load capacity for deep-foundation bridge piers and the lateral resistance required for marine berthing structures. By implementing a one-time cold-forming process imported from Germany, we maintain strict dimensional tolerances-crucial for field splicing and pile driving alignment. Each pipe undergoes rigorous automated ultrasonic testing (AUT) and X-ray inspection to guarantee 100% weld penetration, ensuring that our piles remain structurally sound under high-frequency hammer impacts and long-term corrosive exposure in maritime environments. With an annual LSAW capacity of 300,000 tons and extensive project experience in port and offshore engineering, Huayang delivers the reliability required for the world's most demanding structural foundations.
