Who can say how to prevent outdoor water pipes from freezing?

Take stainless steel water pipes as an example.

When piping outside the house, rainwater can't soak into the external insulation layer, so a waterproof layer should be added to the insulation layer.

There should be no gap between the external insulation material and the pipeline, and it should be fixed.

The thickness of thermal insulation materials should be selected according to local thermal insulation construction standards.

If the temperature inside the pipeline needs sufficient insulation, or in places with high humidity, it is necessary to thicken the insulation layer of the pipeline.

The thermal insulation material may be selected from materials that do not contain soluble halide ions. Thermal insulation materials such as foamed PTFE and phenolic foam are used.
