Hose and Coupling Knowledge Base

In factories, condensation can be seen where water drops collect on tubes carrying coolant. When moisture in the air comes into contact with a hose or pipe carrying a cold fluid, that moisture condenses back into water. That water can lead to accidents.

For example, condensation on a pipe can drip onto the floor, creating a slipping hazard. The water can also get into the electrical systems of machines and potentially cause a short or fire.

Factories forced to save energy this year will have to be even more vigilant than usual about temperature differences.

When air conditioning is not available or adequate, polyethylene foam is generally used to insulate hoses.

When attached tightly with no gaps, polyethylene foam prevents condensation at the connecting portions of both hose ends. Because couplings are made of metal, they have a tendency to attract even more condensation than hoses. Because the coupling portion changes in size, care is needed to make sure the foam fully covers the coupling, leaving no gaps.

Toyox sells hoses already covered in insulation, as well as insulating coupling covers that leave no gaps. We invite you to try them.
