The performance analysis of polyurethane direct buried insulation pipes is a crucial aspect for industries that rely on efficient thermal management. Dacheng Xiangdong Insulation Refractory Material Factory, with contact numbers 13473696600 and 15731614448, provides high-quality solutions in this field. These pipes are designed with a multi-layer structure, consisting of a steel working pipe, a rigid polyurethane foam insulation layer, and an outer protective layer made of high-density polyethylene (HDPE). This combination ensures durability and protection against external damage during transportation, installation, and operation.
The HDPE outer casing is highly resistant to mechanical stress and environmental factors, making it ideal for long-term use in various conditions. The insulation layer, made of rigid polyurethane foam with a density exceeding 60 kg/m³, fills the space between the inner steel pipe and the outer casing completely. Its strong adhesion properties ensure that all components form a solid, integrated unit, enhancing the structural integrity and thermal efficiency of the system.
Polyurethane direct-buried insulation pipes have become widely popular due to their excellent thermal insulation properties. Since its development, rigid polyurethane foam has been recognized as one of the most effective insulating materials. It is used in a variety of applications, including heating, cooling, oil, and gas pipelines. Its ease of installation, energy-saving capabilities, and resistance to corrosion make it a preferred choice in many industrial projects.
The construction process is straightforward, allowing for on-site pouring or pre-formed application of the polyurethane foam onto the steel pipe’s anti-corrosion layer. This method not only speeds up the installation but also improves work efficiency. With a low thermal conductivity, polyurethane foam minimizes heat loss, ensuring optimal energy performance. Additionally, its closed-cell structure, which exceeds 92%, makes it highly waterproof, anti-corrosive, and resistant to aging. This feature helps prevent moisture and aggressive substances from penetrating the pipe, reducing the risk of microbial growth.
These pipes are also known for their strong adaptability. Polyurethane foam can bond effectively with different materials, making it suitable for challenging environments such as coastal areas, marshlands, saline-alkali regions, and river crossings. Compared to traditional trench-based systems, direct-buried polyurethane pipes require less infrastructure investment and offer better economic returns. Moreover, they eliminate concerns about poor adhesion between the insulation and anti-corrosion layers.
The polyurethane insulation layer can withstand temperatures ranging from -196°C to +120°C, with short-term exposure up to +190°C. This wide temperature range allows for flexibility in production and application. If higher temperatures are required, special high-temperature materials can be used to meet specific user needs.
