Shipboard CIP Tank Selection

Storing Shipboard CIP Chemicals? Start Here

Shipboard Clean-in-Place (CIP) systems are essential for maintaining cleanliness in marine environments, from fishing vessels to cruise ships. The process involves a series of cleaning steps using alkaline, acidic, and sanitizing solutions to ensure equipment is food-safe without disassembly. These chemicals are typically stored in HDPE or XLPE tanks, ranging from 200 to 3,000 gallons, at sea or dockside facilities. It's crucial to choose the right tank material to handle the specific chemicals involved in the CIP process.

Can you store it in a poly tank?

Yes, HDPE and XLPE tanks are suitable for storing Shipboard CIP chemicals at ambient temperatures. They are widely used for storing alkaline, acid, and sanitizer concentrates in marine environments. However, for sustained heated service, materials like stainless steel or polypropylene are preferred.

Key Issue: Temperature Sensitivity

While HDPE and XLPE tanks are excellent for ambient storage, they are not suitable for sustained high-temperature applications. For heated CIP loops, materials such as 304/316L stainless steel or polypropylene are recommended to withstand the higher temperatures without degrading.

The safety that actually matters

• Ensure tanks are compatible with the specific chemicals used in your CIP process.
• Use appropriate gaskets and fittings, such as EPDM for caustics and Viton for acids.
• Regularly inspect tanks and fittings for signs of wear or chemical attack.

Common questions

What materials are best for heated CIP loops?

304/316L stainless steel and polypropylene are recommended for heated applications.

Can I use HDPE tanks for all CIP chemicals?

HDPE is suitable for ambient storage of most CIP chemicals but not for sustained heated service.

How do I choose the right gaskets?

Match gaskets to the manufacturer chart based on the specific chemicals used.
