**Common Issues and Solutions for Polyurethane Pipes During Operation – Dacheng Xiangdong Insulation Refractory Material Factory | Contact: 13473696600 / 15731614448**
Polyurethane pipes are widely used in industrial and residential applications due to their excellent insulation properties. These pipes can last between 30 to 50 years, making them a long-term and cost-effective solution. Their superior thermal insulation reduces heat loss by up to 75% compared to traditional piping systems, leading to significant energy savings over time. Additionally, polyurethane pipes offer strong resistance to water and corrosion, making them ideal for both indoor and outdoor installations.
The manufacturing process involves the chemical reaction of high-performance polyether polyol with multiple methyl polyphenyl polyisocyanates, resulting in a durable and efficient insulation material. These pipes are commonly used in central heating systems, air conditioning pipelines, and various industrial applications such as chemical and pharmaceutical sectors.
Despite their advantages, polyurethane pipes can sometimes face operational challenges during installation and use. Here are some common issues and their solutions:
1. **Slow Rise in Polyurethane Pipes**
This issue typically occurs during colder months or early mornings when temperatures drop suddenly. The slow rise is often due to low ambient or black material temperatures. To resolve this, increase the temperature of the black material to 30–60°C and raise the surrounding environment to 20–30°C before application.
2. **Fast Rise in Polyurethane Pipes**
This problem usually happens during warmer seasons or midday construction when temperatures are too high. To prevent this, cool the black material using cold water or store it outdoors at night away from direct sunlight.
By addressing these issues effectively, the performance and longevity of polyurethane insulation pipes can be maximized. For more information or assistance, contact Dacheng Xiangdong Insulation Refractory Material Factory at the provided phone numbers.
