製品の説明
304L Stainless Steel Butt Weld SR 90 Elbow ASME B16.9 Seamless Fitting
1. Product Description
This stainless steel butt welding elbow is a high‑reliability pipe fitting manufactured by hot forging or extrusion. Designed for permanent butt‑welded connections, it provides a smooth, continuous bore that ensures efficient fluid flow with minimal turbulence. The fitting is produced from corrosion‑resistant austenitic stainless steels, primarily 304/L and 316/L, which offer excellent resistance to oxidation, chemical attack, and thermal cycling. Precision machining guarantees accurate bevel geometry and dimensional consistency, making it easy to align and weld on site.
2. Product Applications
The elbow is suitable for fluid handling systems across numerous sectors:
-
Oil and gas – gathering, processing, and transmission pipelines.
-
Chemical and petrochemical – reactor and heat exchanger circuits.
-
Power generation – steam, condensate, and cooling water systems.
-
Pharmaceutical and biotechnology – clean utilities and process lines.
-
Food and beverage – product transfer and CIP loops.
-
Water treatment – desalination, filtration, and distribution.
-
Marine – fuel, ballast, and seawater cooling.
3. Product Advantages
-
Robust construction – hot forming ensures fine grain structure and consistent mechanical properties.
-
Leak‑free guarantee – full‑penetration weld eliminates potential leakage paths.
-
Wide material selection – grades available for ordinary, acidic, high‑temperature, and low‑temperature services.
-
Easy field welding – accurate bevel and uniform wall thickness reduce welding difficulty and inspection rework.
-
Cost‑effective inventory – popular sizes kept in stock, reducing project lead times.
-
Long service life – stainless steel’s passive film offers self‑healing protection in most environments.
