Advantages of PU Hose

Lightweight and flexible, easy to install: PU hose is light in weight, flexible, and has a simple and quick installation process. Compared with traditional metal ducts, it can be easily bent to adapt to complex spatial layouts, reducing the need for additional connectors.

Wear-resistant and long service life: PU material has excellent wear resistance and can withstand the impact of high-speed airflow and particles. This makes ventilation hoses less prone to wear when conveying dust or particles, extending their service life.

Efficient ventilation, improve work efficiency: The inner wall of the PU Hose is smooth, which reduces the friction resistance when the airflow passes through. This design not only improves ventilation efficiency, but also reduces the accumulation of dust and particles in the duct.

Types of PU Hose

Reinforced polyurethane hose: These hoses feature an additional reinforcement layer, such as a spiral wire or braided fabric, to provide enhanced strength and pressure resistance. Ideal for high-pressure applications, hydraulic systems, and heavy-duty industrial environments.

Anti-static polyurethane hose: Designed to dissipate static electricity, these hoses are used in applications where there is a risk of static buildup, such as in explosive or flammable environments.

Food-grade polyurethane hose: Formulated to meet strict food-contact standards, these hoses are suitable for use in the food and beverage industry.They are resistant to chemicals, oils, and microbial growth, ensuring compliance with food safety regulations.

Temperature-resistant polyurethane hose: These hoses are designed to withstand high or low temperatures, depending on the application requirements.

Conductive polyurethane hose: Conductive polyurethane hoses are designed to dissipate static electricity and provide a path for grounding. They are commonly used in applications where there is a risk of static buildup, such as in the handling of flammable liquids or powders.

Transparent polyurethane hose: These hoses feature a clear or translucent construction, allowing for visual inspection of the fluid flow. They are often used in applications where monitoring the fluid condition or identifying potential issues is important.

Applications of PU Hose

PU hose is widely used in glass manufacturing, woodworking machinery, steel smelting, plastic processing, mining, shipbuilding industry, cement production and other fields. As a mechanical conveying and protection pipeline, it demonstrates its strong adaptability and practicality. PU hose has become a trusted conveying solution for many industries with its excellent performance and wide application fields. Whether facing harsh working environments or strict quality requirements, PU steel wire vacuum hose can provide stable and efficient services to help your production process smoother.

Production Process of PU Hose

Raw material preparation

The raw materials used in the production of PU hoses 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 hose. 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 hoses are then subjected to quality control tests to ensure that they meet the required specifications such as diameter, wall thickness, and mechanical properties.

PU Hose Technical Details

The working pressures of this polyurethane tube are based on the short-term burst pressure at a temperature of 20°C using a 4:1 safety factor.

The maximum recommended continuous working temperature is 55°C with occasional short-term use at 85°C. Minimum temperature use is occasional use at -55°C.

The standard coil lengths are 30 metres; however, we provide customised solutions to our sales team if you are looking for alternative coil lengths. We will be happy to talk about your options. All tube sizes are also available in various colours and tints.

Custom PU Hose

Custom numbering can be added to each hose in sequence. This helps in easy identification during installation or when connecting additional tubes, ensuring a smooth process for the user.

The hoses can be manufactured in a variety of colors including yellow, metallic shades, black, etc., to meet aesthetic or functional requirements.

Packaging and Shipping of PU Hose

Packing	Bags, cardboard boxes, and reels
Shipping	Shipped by road, sea, rail or air

FAQ

Q: What is a polyurethane hose used for?

A: Flexible polyurethane tubing is used where air and/or other products need to be transported (via suction or discharge) through materials that have: excellent mechanical resistance, excellent tensile strength, resistance to cutting and abrasion, high flexibility, semi-transparency and limited weight.

Q: Is a polyurethane hose better than a rubber hose?

A: Durability. Polyurethane hose is made of the same material as the wheels on in-line roller skates and is strong enough to withstand potential damages like being pulled across rough or sharp surfaces. The outer cover on the rubber hose is much softer and can tear easily.

Q: What is a polyurethane air hose?

A: Polyurethane Air features a specially formulated compound that stays flexible in subzero temperatures, resists oils and solvents, and doesn't catch or kink on corners.

Q: Are polyurethane hoses safe?

A: Drinking Water Safe - Polyurethane garden hoses are 100% drinking water safe. Rubber hoses are not.

Q: Which is stronger rubber or polyurethane?

A: Here's where a myth about polyurethane needs to be dispelled. It is more durable than rubber and will perform even better under duress. In fact, it can withstand incredible amounts of use and holds its shape even in the presence of friction, abrasion and high-speed kinetic energy.

Q: Is polyurethane hose good for fuel?

A: Polyurethane hose provides the solution where PVC struggles, featuring excellent resistance to most petroleum-based chemicals. This makes it an ideal choice for use in most fuel lines, although testing might be necessary in some cases.

Q: What lasts longer rubber or polyurethane?

A: Longevity: When it comes to longevity, polyurethane is a clear winner. This is due to the tendency of rubber to crack and degrade as time passes. Polyurethane is specifically engineered to last, remaining flexible and functional much longer than rubber.
