Single-use and reusable transfer lines

Technical explanation

The manufacturer's intended use is a basic input in evaluating the material and fitting design. For reuse, cleaning, sterilization, inspection and replacement conditions are defined. In the single-use approach, topics such as as-delivered condition, packaging integrity, assembly and waste management become important. Even if the material of a product is the same, its manufacturing and use scope may differ. The quality acceptance of the process is not considered complete on the basis of a general product family name.

How is it assessed in practice?

In the comparison, add not only the purchase price but also the controls and operations the facility needs to the table. For example, the rationale for the options may differ between a line with frequent product changeovers and a line running continuously on the same product. Do not accept a reuse scenario not foreseen by the manufacturer on the assumption of a cost advantage. The decision file should clearly state the basis for the number of uses or the cycle definition, the packaging requirement and the process acceptance method.

Frequently asked questions

Can I reuse a single-use hose because it looks good?

This conclusion cannot be drawn without acceptance by the manufacturer and the facility's quality system. Appearance does not verify all the requirements for reuse.
