Product Long Radius Bend
Long radius bends are specialized pipe fittings used to change the direction of piping systems with a smooth, gradual curve. These bends are essential in various industries, including oil and gas, water treatment, and HVAC, where they help minimize pressure loss and turbulence in fluid or gas flow. Unlike short radius bends, long radius bends offer a larger radius of curvature, which helps in reducing friction and extending the lifespan of piping systems. They are particularly useful in applications where the flow rate is high and pressure drop needs to be minimized.

Product Specifications
Radius
The defining characteristic of a long radius bend is its radius of curvature. Typically, the radius is 1.5 to 2 times the nominal pipe diameter. For example, in a 90-degree long radius elbow, the radius of curvature is 1.5 to 2 times the diameter of the pipe.
Material
Long radius bends can be made from various materials, including carbon steel, stainless steel, alloy steel, and plastic. The choice of material depends on the application, including factors such as temperature, pressure, and corrosion resistance.
Angle
Long radius bends are commonly available in standard angles such as 45 degrees, 90 degrees, and 180 degrees. Custom angles can also be produced based on specific requirements.
Pipe Diameter
Long radius bends are manufactured to fit various pipe diameters, from small residential pipes to large industrial pipelines. Standard sizes are available, but custom diameters can be fabricated as needed.
Wall Thickness
The wall thickness of long radius bends varies based on the pipe's pressure rating and material. It is crucial to select the appropriate thickness to ensure the bend can withstand the operating conditions.
Pressure Rating
Long radius bends are designed to handle specific pressure ratings based on their material and construction. It's important to choose bends with pressure ratings suitable for the system's operating conditions.
Standards and Codes
Long radius bends are often manufactured according to industry standards such as ASTM, ASME, or ISO. Common standards include ASTM A234 for carbon steel bends and ASTM B16.9 for wrought steel fittings.
Finish
The surface finish of long radius bends can vary, including options such as bare metal, coated, or lined finishes. The finish may be selected based on the environmental conditions and requirements of the application.
