In warm and humid seasons, bathrooms with heating, rooms with high working temperatures and larger air humidity (such as kitchens, laundry rooms, and certain production workshops), or when the water temperature in pipes is lower than room temperature, condensation may form on the outer walls of pipes and equipment. Over time, this can damage walls, cause pipe corrosion, and affect usage and environmental hygiene. Therefore, anti-condensation measures must be taken, such as creating a moisture-proof insulation layer. The method for creating a moisture-proof layer is generally the same as that for insulation.
For water supply pipes installed indoors where the temperature is below zero degrees, frost prevention should be considered. After the pipe installation is completed and after pressure testing and rust removal from the pipe's outer surface followed by applying anti-corrosion paint, insulation and frost prevention measures should be taken.
Wrap the pipes with cotton felt (referring to rock wool, ultra-fine glass wool, fiberglass, and slag wool felt) to create an insulation layer, then wrap it with a glass fiber cloth protective layer and coat the surface with a blended paint.
Use insulation tiles (foam concrete, diatomite, cement vermiculite, foam plastic, rock wool, ultra-fine glass wool, fiberglass, slag wool, and cement expanded perlite) for pipe insulation layers. Wrap them with a glass fiber cloth protective layer and apply blended paint on the surface. |
