Is it permissible to manifold tanks of different diameters?

Manifolding tanks of different diameters is not permissible due to several safety and operational concerns. When tanks have different diameters, they can have varying pressure and flow characteristics. This can lead to uneven distribution of product, which presents risks such as overfilling or inadequate filling of one tank compared to another.

Additionally, if one tank is significantly smaller, it may not be able to handle the same pressures that a larger tank can, which raises concerns about structural integrity and leak potential. Tank management becomes more complicated when differing sizes are involved, potentially resulting in regulatory violations or safety hazards. Uniformity in tank size helps maintain consistent operational practices and simplifies the manifold design, thereby promoting safety and compliance with regulations.
