Products Description

 

LSAW (Longitudinal Submerged Arc Welded) Steel Pipe for Piling is fully compliantASTM A252standard, mainly used in deep foundation engineering scenarios commonly seen in Southeast Asia, suchmarine reclamation, port expansion, cross-sea bridges, high-rise building foundations, and mine infrastructure. It is available inASTM A252 Grade 2(cost-effective type) andGrade 3(heavy-load type), perfectly matching the construction needs of Southeast Asia's tropical coastal environment, typhoon-prone areas, and soft soil foundations.stable quality, fast delivery, and RCEP tariff preferences, it has been widely applied in key projects in Malaysia, Singapore, Vietnam, Indonesia, Thailand and other countries.

Key Advantages

 

◆ High Adaptability to Local Environment: Optimized for Southeast Asia's tropical coastal climate, strong resistance to marine salt spray, humidity, and soft soil corrosion; Grade 3 is specially designed for typhoon-prone areas (Philippines, Vietnam) and high seismic intensity regions, with 30% higher deformation resistance than spiral welded pipes.

◆ Cost-Effective & High Performance: Grade 2 is the preferred choice for most SEA projects, balancing quality and price; Grade 3 meets the requirements of key heavy-load projects (large ports, cross-sea bridges) without excessive cost increase. RCEP tariff preferences further reduce customer procurement costs.

◆ Reliable Weld Quality: Adopt double-sided submerged arc welding technology, 100% non-destructive testing, zero weld defects, ensuring the stability of piling foundation in long-term service; comply with ASTM A252 full standard, pass SGS third-party inspection.

◆ Easy Construction: Light weight (compared with seamless steel pipe) and reasonable structure, reducing on-site hoisting and installation difficulty; customized beveling design ensures quick connection of piles, improving construction efficiency.
