Function and feature of PU flexible hose

PU flexible hoses are widely used because of their lightweight and flexible characteristics, and they come in different diameters and lengths. They have specific features and functions.

• Lightweight

  PU flexible hoses are lightweight, making them easy to handle and install. This reduces the amount of energy used during transportation and movement at the work site, which in turn reduces labor costs. Their lightweight characteristic also means that minimal support is required during installation.

• Flexibility

  These hoses are highly flexible, allowing them to be used in applications that require rotational or directional movements. Their flexibility allows them to be connected to machines and tools that are in tight corners and spaces.

• PU flexible hose durability

  These hoses are made from thermoplastic polyurethane, which offers them a long lifespan. This material is puncture and abrasion-resistant, which prevents the hose from ripping and tearing when exposed to harsh environments. They can work under various temperatures, which prevents them from melting or freezing.

• Compression ability

  These PU flexible hoses can be compressed to a certain degree, which allows them to save space when they are not in use. This means that when these hoses are stored, transportation, warehousing, and storage costs are reduced. The ability of these hoses to compress reduces the risk of damage due to kinking or twisting.

• Chemical resistance

  The PU flexible hose is resistant to harsh chemicals and fluids. This prevents the hose from being damaged or leaking, which can cause environmental hazards. It also ensures the safety of the workers and prevents hoses from bursting.

• Compatibility with fittings

  These flexible hoses come in different diameters and sizes, making them easy to connect with various tools and machinery. This increases their versatility because they can be used in different applications, such as agricultural, industrial, and construction.

• Reduced friction

  These PU flexible hoses have a smooth interior lining that reduces friction when fluids or air pass through. This allows for a consistent and steady flow of fluids, increasing efficiency. The smooth surface also minimizes the loss of pressure, which ensures that the hoses last longer.

Scenarios of PU Flexible Hose

PU flexible hoses are widely appreciated for their light weight and flexibility. Their application spans different industries, from automotive to construction, electronics, and beyond.

• Automotive industry

  PU flexible hoses are widely used in the automotive industry. They are often used as air ducts in automotive engineering, connecting the air intake manifold to the engine. Their ability to withstand varying temperatures and lightweight nature makes them a suitable choice for this application. These flexible PU hoses are also used in the HVAC systems of cars. They are used to channel air from the HVAC unit to different parts of the car interior. Their flexibility allows them to fit into the tight spaces within the car.

• Electrical industry

  PU flexible hoses are also widely used in the electrical industry. They are used to manufacture cable protection conduits. These conduits protect electrical cables from abrasion, chemicals, and mechanical damage. Their flexibility allows them to be used in applications where rigid conduits cannot fit. They are also used to make wire covers. These covers not only enhance the flexibility of wires but also improve the aesthetic appearance of wires.

• Construction industry

  PU flexible hoses have a wide variety of applications in the construction industry. They are used to make ventilation ducts that are used for air distribution in buildings. They are also used to make HVAC ducts. Their lightweight nature makes them easy to install. They are also used to make PEX pipes that are used for plumbing in buildings. Their flexibility allows them to fit into complex building architectures.

• Manufacturing Industry

  Flexible PU hoses are extensively used in manufacturing. They are used to create pneumatic tubes that transport air in a system. Their lightweight nature and efficient air transport make them suitable for this application. They are also used in the dust collection system to create flexible connections that transport dust particles to the collection point.

How to Choose PU Flexible Hose

• Size:

  The right size is important for efficiency. A pump flexible coupling hose should not be too small or too large. A small hose will restrict flow, while a large hose will increase pressure. Experts recommend choosing a hose compatible with the pump outlet and the application.

• Material:

  The materials used to make the PU flexible hose affect its performance. PU hoses are lightweight and durable, making them suitable for air and water applications. PVC hoses are more affordable and versatile but have a shorter lifespan than PU hoses. Consider the application to choose the best material.

• Temperature and pressure ratings:

  Every application has its own temperature and pressure ratings. It's important to choose a hose with the right pressure and temperature ratings. This ensures it will survive in those conditions. Selecting a hose without considering these factors can cause it to burst or damage.

• Compatibility:

  The PU flexible hose must be compatible with the fluids or gases that will pass through it. This prevents leaks and hose damage. For example, some hoses are compatible with abrasive materials, while others are not. Check the manufacturer's specifications to choose the right PU flexible hose.

• Kink resistance and flexibility:

  Hoses are installed in tight areas and moved around often. Therefore, it is important to choose a hose that can bend easily without breaking or kinking. Kink-resistant hoses offer better flow and are durable.

• Brand reputation:

  A good manufacturer produces quality PU flexible hoses. This ensures durability and safety. Consider the reviews and ratings of different manufacturers before buying. Choose a manufacturer with positive reviews.
