Stainless steel (SS) expansion bellows absorb thermal expansion, contraction, vibration, and minor misalignments in industrial piping systems. Standard specifications typically cover grades like SS304 or SS316, size ranges from 1 inch to 48 inches (25 mm to 1200 mm), pressure ratings from PN16 to PN40 (50–300 psi), and temperatures up to 420°C. Key Technical Parameters • Material Grades: SS304, SS304L, SS316, or SS316L for optimal corrosion and high-temperature resistance. • Bore/Diameter Size: 1 inch up to 48 inches (customizable for large industrial ducts). • Design Pressure: Standard PN16, PN25, PN40, or 50 to 300 psi depending on duty. • Temperature Range: -20°C to +420°C (varies by material grade and ply construction). • Ply Construction: Single-ply or multi-ply (2-ply/3-ply) bellows for enhanced flexibility and safety. Movement and Connections • Movement Types: Axial compression/expansion, lateral offset, and angular rotation. • End Connections: Flanged, welded (butt-weld), or threaded/male-connecting ends. • Accessories: Tie rods, limit rods, inner sleeves (liners), and lifting lugs for high-thrust setups.
