Analysis Of The Moisture Resistance Of Pre-insulated Sleeves

pre insulated sleeve exhibits excellent moisture resistance, providing a foundation for long-term environmental stability. pre insulated junction sleeve typically consists of three parts: a carrier tube, an insulation layer, and an outer sheath. The overall structure demonstrates excellent moisture barrier capabilities in humid environments.

The inner carrier tube is made of materials with high corrosion resistance, such as stainless steel or weather-resistant engineering plastics. These materials maintain structural integrity even under moisture penetration conditions, thus reducing the risk of moisture intrusion into the internal metal or sensitive media. The tightly integrated insulation layer reduces the path of moisture diffusion through dense material arrangement, while the outer sheath uses a weather-resistant polymer to improve the thickness and uniformity of the overall moisture barrier of insulated joint sleeve.

Modern insulation materials reduce the possibility of water molecule penetration at the molecular level, showing a significant downward trend in the water vapor permeability coefficient. The sheath material is specially formulated to withstand the alternating effects of long-term low-temperature and high-humidity environments, maintaining stable physical properties.
