The difference between hot water hose and steam hose

Technical explanation

Liquid water, saturated steam and superheated steam are different operating conditions. The steam hose standard specifically addresses steam service. Using a product suitable for hot water for steam or steam sterilization can only be considered with the manufacturer's explicit scope. The connections and seals must also meet the same conditions. Supplying steam briefly during cleaning does not make steam exposure insignificant or automatically permitted.

How is it assessed in practice?

Write down the usage scenarios for a cleaning line: normal water washing, hot solution and, if any, steam treatment should be separate rows. For example, operators being able to connect the same connection to different sources can increase the likelihood of misuse; assess this in labeling and the facility's connection arrangement. In the quotation text, write which services are accepted instead of a vague heading such as 'high-temperature hose'. Services that are not accepted can also be stated explicitly.

Frequently asked questions

Is separate confirmation needed for brief steam passage?

Yes. A short duration does not on its own provide suitability. The permitted exposure conditions of the product and assembly must be verified.
