Smooth flow guidance Durable construction 45° BW Long Radius Elbow ASMEB16.9 Class 300

1. Product Description
A 45° BW Long Radius Elbow is a pipe fitting that changes the direction of a pipeline by 45 degrees. Its key geometric feature is a Long Radius (R=1.5D), meaning its curvature radius is 1.5 times the pipe's nominal diameter, which ensures a smoother flow path compared to short-radius elbows. It is primarily designed for butt-welding (BW) connection, creating a strong, permanent joint with the pipe. These elbows are manufactured according to international standards such as ANSI B16.9 and are available in various materials like carbon steel (e.g., ASTM A234 WPB), stainless steel (e.g., 304/316), and alloy steels.

2. Product (Application)
This elbow is widely used across multiple industries to alter pipeline direction in fluid transport systems. Its primary function is to facilitate a smooth change in flow direction with minimal turbulence. Common applications include systems in petroleum, natural gas, chemical, power generation, and water disposal projects, as well as in construction and shipbuilding. It is suitable for conveying liquids, gases, and steam.

3. Product (Advantages)

Smooth Flow & Low Pressure Drop: The long-radius design provides a gentle bend, which reduces flow resistance and minimizes pressure loss in the system. This contributes to improved energy efficiency.

Durable & High-Pressure Capability: Constructed from robust materials and connected via butt welding, these fittings form a strong, leak-proof joint capable of withstanding high pressure and offering long service life.

Reduced Erosion & Vibration: The smooth inner surface and gradual bend help minimize turbulence, which lowers the risk of erosion and corrosion at the bend. The rigid welded connection also helps in dampening vibration.
