What Is Urethane Tubing?
Urethane tubing, known for its pressure resistance, flexibility, and ease of handling, is extensively used across various industries. It is commonly used for transporting air and water. Available in translucent, white, and black, it also comes in vibrant colors like green, blue, and red, with a range of tube diameters.
Specialized types include conductive urethane tubing for anti-static measures, oil- and weather-resistant tubing, and an even more flexible variant known as soft urethane tubing.
Uses of Urethane Tubing
Its applications span from general pneumatic piping to cooling water piping. Pneumatic piping utilizes urethane tubing for air control in panels, machines, and vacuum systems. It’s also employed in tubing for assembly equipment, semiconductor processing, scientific instruments, and pesticide spraying via drones. Due to its cost-effectiveness and ease of processing, it’s utilized in coiling and welding processes, with one-touch connections made possible through dedicated fittings.
Principle of Urethane Tubing
Urethane tubing’s flexibility makes it a preferred choice for general piping needs. It remains durable with minimal mold growth or deterioration, even in humid conditions. Available in soft, rigid, and semi-rigid materials, it primarily uses ether-based polyurethane resins. Soft urethane offers the most flexibility, whereas rigid urethane provides a slightly firmer structure, both softer than nylon tubing. However, its temperature tolerance is generally low, around 60°C, with heat-resistant variants only withstanding up to 80°C. For high-pressure applications, nylon tubing is recommended, while Teflon tubing is advised for chemical resistance, noting that urethane tubing is produced through extrusion molding.
Types of Urethane Tubing
1. Breathable Urethane Tubing
This type allows air and gases to pass through, making it ideal for air brake systems, air filters, and exhaust systems, especially in automotive applications for engine exhaust and brake operation control.
2. Pressure-Resistant Urethane Tubing
Enhanced for high-pressure resistance, this tubing is used in hydraulic systems, air conditioning, and liquid supply systems, as well as in transportation equipment like aircraft and automobiles for reliable high-pressure liquid transport.
3. Abrasion-Resistant Urethane Tubing
Designed for high abrasion resistance, this tubing withstands friction and wear, suitable for conveyor belts, slurry pipes, and grinding equipment, particularly in mining and construction where durability is crucial.
4. Heat-Resistant Urethane Tubing
Made for high-temperature environments, it’s used in engine parts, heater systems, and hot-air blowers, maintaining properties under high temperatures. Its electrical insulation and chemical resistance make it fit for electrical components and the chemical and medical industries.
