Stainless Steel (SS) and Carbon Steel (CS) buttweld fittings are industrial pipe components designed to be welded on-site to connect pipes permanently, ensuring leak-proof, high-pressure, and high-temperature performance. Made to ASTM/ASME standards (e.g., A403 for SS, A234 WPB for CS), they offer superior strength in piping systems. Key Characteristics Connection Method: Beveled ends are welded directly to pipe, reducing leaks and flow turbulence. Types: Common fittings include long/short radius elbows ( , , ), equal/reducing tees, concentric/eccentric reducers, and caps. Construction: Available as seamless (for high pressure) or welded (for larger, less critical applications). Sizes: Typically range from inch to inches, with larger custom sizes available. Material Distinctions Stainless Steel (SS): Commonly Grade 304/304L or 316/316L. Known for high corrosion resistance and used in chemical, pharmaceutical, and food industries. Carbon Steel (CS): Commonly ASTM A234 WPB. Offers high mechanical strength, typically used in oil & gas, water, and structural applications.
