What thickness is recommended for holding tanks made of linear or cross-linked polyethylene?

The recommended thickness for holding tanks made of linear or cross-linked polyethylene is 1/4 inch. This thickness is generally considered adequate to provide the necessary strength and integrity to withstand the pressures and potential impacts that holding tanks may encounter during operation on a vessel.

Linear and cross-linked polyethylene are chosen for holding tanks due to their excellent chemical resistance, durability, and efficient performance in marine environments. A thickness of 1/4 inch strikes a balance between ensuring sufficient structural strength and weight considerations. Thinner materials may not withstand the dynamic conditions and stresses inherent in a marine setting, while thicker materials could unnecessarily increase weight and material costs, potentially impacting the vessel's overall performance and handling.

It is essential to adhere to these guidelines to ensure the safety and longevity of the holding tank, minimizing the risks of leaks or failures that could lead to environmental hazards or costly repairs.
