Stainless Steel Reducer Weight Chart

ASME B16.9

S&S Stainless International offers an accurate stainless steel reducer weight reference guide to help piping designers, procurement managers, and freight forwarders easily determine individual fitting weights and total container payload capacities. Engineered to join pipes of differing diameters, our butt-weld reducers are available in both concentric (centerline aligned) and eccentric (flat side offset) configurations per ANSI/ASME B16.9 and MSS SP-43 standards. Forged and precision-machined from dual-certified 304/304L and 316/316L stainless steel, our comprehensive weight tables list exact unit weights across all standard wall thickness schedules—from Schedule 5S to Schedule 80S—ensuring precise dead load calculations, streamlined ocean freight consolidation, and efficient B2B global procurement.
