Advantages of PU Pipe
High Pressure Resistance
PU tubes can withstand high pressure, making them highly reliable in pneumatic applications and fluid transfer systems.
Lightweight Nature
The lightweight nature of polyurethane makes PU tubes ideal for applications where weight reduction is essential, such as in pneumatic control systems and dynamic environments.
Excellent Abrasion Resistance
Polyurethane Tubes offer excellent abrasion resistance, outperforming other materials like PVC hoses and nylon tubing in harsh conditions.
High & Low Temperature Resistance
PU tubing can withstand extreme temperatures, both high and low, making it versatile for operating conditions ranging from industrial settings to food processing.
Oil Resistance and Chemical Resistance
Polyurethane Tubes are resistant to oils, greases, and many chemicals, making them suitable for various applications in the automotive and pharmaceutical industries.
Affordability
PU Tubes are an economical option compared to other tubing materials, providing cost savings without compromising on quality.
Low Maintenance
With high durability and resistance to wear and tear, PU hoses require minimal maintenance, reducing long-term operational costs.
Energy Efficiency
The lightweight nature of PU tubing contributes to energy savings in systems requiring constant movement or transport of air, making it an ideal choice for pneumatic systems.
Pu Pipe Production Process
PU polyurethane tube is a type of plastic tube that is widely used in industries such as automotive, construction, and food processing. The production process of PU tubes involves the following steps:
Raw material preparation: The raw materials used in the production of PU tubes are polyurethane resin, curing agents, chain extenders, and catalysts. These materials are mixed together in a specific ratio based on the desired properties of the final product.
Mixing: The mixed raw materials are then fed into a mixing chamber where they are mixed together using a high-speed impeller. The mixture is then heated to a specific temperature to promote polymerization.
Extrusion: The mixed and heated material is then extruded through a die to form the desired shape and size of the PU tube. The extruded tube is cooled down and cut into specific lengths.
Post-processing: The cut tubes are then subjected to post-processing operations such as polishing, smoothing, and surface treatment to improve their properties and appearance.
Quality control: The finished PU tubes are then subjected to quality control tests to ensure that they meet the required specifications such as diameter, wall thickness, and mechanical properties.
Step-by-Step Guide to Installing PU Pipe
Preparation
Gather all necessary tools and materials before starting the installation process. This includes the PU tubes, fittings, cutting tools, and any other equipment required for the installation.
Connecting
Use appropriate fittings to connect the tube to the system. Ensure a secure fit to avoid any air or fluid leaks. It’s essential to follow the manufacturer’s guidelines for the specific fittings used.
Cutting
Use a sharp knife or tube cutter to cut the PU tube to the desired length. Ensure a clean cut to prevent leaks and ensure a proper fit with the fittings.
Testing
After installation, conduct tests to check for leaks and ensure the system operates correctly. This step is crucial to identify any issues before the system is put into full operation.
(1) Please use a professional pipe cutter to cut the required length. This can ensure the flatness and roundness of the cross-section of the PU pipe mouth. When assembling a PU tube, insert its mouth vertically into the bottom of the fitting. And pull it outward to ensure a successful connection.
(2)When bending the PU Pipe, please pay attention to the smallest bending radius requirements. Excessive winding, stretching, and twisting of the PU pipe will directly affect the working capacity and even break.
(3)When storing PU Pipe, put them in a ventilated and dry place. Storing in a damp place or the storage period is too long, will hydrolyze or age the hose, which may lead to breakage.
(4)The normal working pressure is 0-8bar, the max. pressure is 10bar, pls don’t use it in an environment above this pressure. Also do not allow the tube to be frictionally wound, stretched, or twisted too much, otherwise. It will be damaged and the working pressure will be affected also.
Application of PU Pipe
Pneumatic Operations in the Automotive Industry
The pneumatic operations are performed in most production lines, especially where high-pressure spray, air filling, or mechanical force is required. The automotive industry is all about installing machine parts with pneumatic tools.
Fluid Transfer in Construction and Agriculture
Both industries need to deal with regular fluid transfer, like cement, water, chemicals, and even a few specific gases. The pneumatic and spray machines need polyurethane pipes to carry fluids and gases.
Spraying, Fluid Transfer, and Fume Extraction in Various Industries
Industrial operations like spraying, fluid transfer, and fume extraction need pipes that can withstand high pressure. This is where PU pipes and hoses work well. Various types of fluids need to be transferred, whether for cooling or any other purpose.
Medical Industry for Gas and Fluid Transfer
Since the medical industry must prioritize hygiene and biocompatibility, they need something that can meet their needs. Medical-grade PU hoses and pipes can offer great support without any risk, such as leaching or exploding.
Food-Grade PU for the Food and Beverage Industry
Then another sensitive industry comes where safety is of utmost importance. Even a small amount of negligence could cause irreparable damage to humans and animals, which is a nightmare for everyone. Therefore, food-grade PU pipes and hoses are used in some food and beverage applications.
Garden, Pool, and Sanitary Applications in the Domestic Sector
The most common use of PU hoses in the domestic sector is in gardening, pool maintenance, and sanitary applications. These hoses and pipes offer significant benefits in terms of flexibility, pressure resistance, versatility, and abrasion resistance.
