Stainless steel (SS) buttweld fittings are designed for permanent, high-strength piping connections, primarily in industrial applications requiring corrosion resistance and flow control. Common types include 45°/90°/180° elbows, concentric/eccentric reducers, tees, caps, and stub ends. They are usually manufactured in ASTM A403 grades (WP304/304L, WP316/316L) to ASME B16.9/B16.25 standards, ranging from SCH 10 to XXS.Key Types of SS Buttweld Fittings:Elbows (45°, 90°, 180°, LR/SR): Changes the direction of flow. Long Radius (LR) provides gradual changes, while Short Radius (SR) is for tight spaces.Reducers (Concentric & Eccentric): Connects pipes of different diameters. Concentric keeps alignment, while eccentric is used to keep one side flat, often for drainage.Tees (Equal & Reducing): Branches the pipe into two paths.Caps & Stub Ends: Used to seal the end of a pipe (cap) or create a flange connection (stub end).Crosses: Used in piping to create a four-way connection.Key Specifications & Materials:Materials: ASTM A403 WP304/304L, WP316/316L, 304H, 316H, 317/317L, 321, 310, 904L, and Duplex Stainless Steel.Standards: ANSI/ASME B16.9 (Dimensions), ASME B16.25 (Buttweld Ends), ASTM A403 (Material Specification).Sizes: Commonly available from 1/8” NB up to 48” NB (specialized up to 72”).Thickness (Schedule): SCH 5s, 10s, 40s, 80s, SCH 10, 20, 40, STD, 60, 80, XS, 100, 120, 140, 160, XXS.Applications:Oil and Gas pipelinesChemical processing and petrochemical industriesPower generation plantsPharmaceuticals and food processingBenefits:Continuous Structure: Provides high strength and leak-proof joints.Corrosion Resistance: Excellent durability in harsh environments.Low Maintenance: Long-lasting with minimal need for repair.
