Mandrel Bending of Tube and Pipe for Pneumatic Conveying

Smooth Flow Path: 

Mandrel bending minimizes deformation and wrinkles on the inner surface of the bend. This results in a smoother flow path for the conveyed material, reducing the risk of blockages and turbulence that could affect conveying efficiency.

Consistent Diameter: 

Since the mandrel provides internal support, the pipe retains a more consistent diameter throughout the bend. This helps maintain the desired conveying capacity and minimizes pressure drop.

Reduced Wear: 

A smoother inner surface reduces wear and abrasion on the bend, prolonging the lifespan of the bend and reducing the potential for material degradation.

Accurate Bending: 

Mandrel bending offers precise control over bend angles and radii, ensuring that the bends conform to the specific requirements of the pneumatic conveying system.

Minimized Impact on Material: 

By maintaining a smooth and consistent flow path, mandrel bending reduces the impact of the bend on the conveyed material. This can be particularly important for sensitive materials that are prone to breakage or degradation.

Improved System Efficiency: 

The smoother flow path, reduced wear, and accurate bends contribute to improved overall system efficiency and lower energy consumption.


It is important to note that while mandrel bending offers several benefits for pneumatic conveying bends, the specific design considerations and material selection still apply. The choice of bend radius, bend angle, material, and overall system layout are important factors that should be considered to ensure optimal pneumatic conveying performance.
