P U Pipe FAQ Section
1. What makes P U pipe better than traditional rubber hoses?
P U pipe offers several advantages over rubber hoses. The polyurethane material provides superior abrasion resistance, up to 10 times better than rubber in many applications. P U pipe maintains flexibility at lower temperatures while offering higher pressure ratings. Additionally, P U pipe has better resistance to oils, chemicals, and UV radiation, making it more durable in harsh environments. The smooth inner surface also reduces friction loss compared to rubber hoses.
2. How do I determine the right P U pipe size for my application?
Selecting the correct P U pipe size depends on three main factors: flow requirements, working pressure, and compatibility with your existing fittings. For flow requirements, consider both the inner diameter (which affects flow rate) and length (which affects pressure drop). Always choose a pipe with a pressure rating at least 25% higher than your maximum system pressure. Our technical team can assist with sizing recommendations based on your specific application parameters.
3. Can P U pipe be used for drinking water applications?
Standard P U pipe is not recommended for potable water applications. However, we offer special food-grade P U pipe that meets NSF/ANSI 61 drinking water standards. These pipes use specially formulated polyurethane that doesn't leach harmful substances and includes antimicrobial properties. Always verify certifications before using any P U pipe for drinking water applications.
Installation and Maintenance Tips
Proper installation is crucial for maximizing the performance and lifespan of your P U pipe. Always use compatible fittings designed for polyurethane tubing, and avoid sharp bends that could kink the pipe. Regular inspections should check for abrasion, especially in high-movement areas. When storing P U pipe, keep it coiled loosely in a cool, dry place away from direct sunlight.

Additional P U Pipe FAQ
4. What is the typical lifespan of P U pipe?
Under normal operating conditions, our P U pipe typically lasts 5-7 years in continuous service. However, lifespan varies significantly based on application factors like working pressure, temperature extremes, exposure to chemicals, and mechanical stress. Regular maintenance and proper installation can extend service life. We recommend replacing P U pipe at the first signs of cracking, hardening, or significant abrasion.
5. Can P U pipe be repaired if damaged?
While minor surface abrasions may not require immediate attention, significant damage to P U pipe generally warrants replacement rather than repair. Unlike rubber hoses that can sometimes be spliced, P U pipe's performance characteristics are best maintained by using undamaged sections. For critical applications, we never recommend attempting repairs on pressurized P U pipe lines.
6. How does temperature affect P U pipe performance?
P U pipe maintains excellent flexibility at low temperatures (down to -40°C) while retaining strength at elevated temperatures (up to +90°C continuous). However, temperature extremes do affect pressure ratings - the maximum working pressure decreases as temperature increases. For every 10°C above 20°C, derate the maximum pressure by approximately 10%. Similarly, at very low temperatures, the pipe becomes stiffer but maintains its pressure capabilities.
