S347H Material Performance
S347H (UNS S34709) offers excellent creep, intergranular corrosion, and stress rupture resistance. Its strong weldability (compatible with ER347H welding wire) and forming properties maintain structural integrity in extreme conditions, reducing leaks and costly repairs.
S347H pre-fabricated pipe spools Time and Cost Efficiency
Workshop pre-fabrication avoids on-site chaos and weather delays, cutting installation time by up to 40%. Precise cutting, beveling, and welding reduce material waste and rework, lowering overall project costs.
Application of S347H pre-fabricated pipe spools
Oil and gas: submarine pipelines, downhole tools for acid gas wells.
Chemical equipment: sulfuric acid reactors, phosphoric acid evaporators, pickling equipment.
Nuclear industry: containers and pipelines for nuclear waste treatment systems.
Marine engineering: seawater desalination devices, heat exchangers.
Environmental protection: key components of flue gas desulfurization (FGD) systems.
