Application of Tekalan lines 

Pneumatic hoses are widely used in various industries and applications where it is necessary to transfer compressed air or other gases. Three popular types of pneumatic hoses are PA (polyamide), PU (polyurethane), and PE (polyethylene) hoses. Each of these materials has its unique properties that affect their use in different applications. In this article, we will discuss the main differences between these three types of pneumatic hoses.

Lines for pneumatic installations PA (polyamide) hoses

PA hoses are made of high-quality polyamide. They are characterized by high tensile and compressive strength, as well as resistance to wear and aging. PU (polyurethane) hoses: PU hoses are made of flexible polyurethane. They have excellent abrasion resistance, flexibility, and tensile strength. PE (polyethylene) hoses: PE hoses are made of low-density polyethylene. They are lightweight, flexible, and resistant to chemical wear. Flexibility and bending resistance: PA hoses: PA hoses are relatively rigid and less flexible compared to PU and PE hoses. They may have greater durability in applications where minimal bending is required. PU hoses: PU hoses are very flexible and bend easily. They can be used in applications that require high flexibility and bending resistance. PE hoses: PE hoses are flexible and resistant to bending, making them suitable for applications where frequent bending of the hose is required.

Working pressure of polyamide hoses 

PA hoses: PA hoses typically have lower working pressure compared to PU and PE hoses. They are suitable for lower pressure applications, such as pneumatic systems with lower requirements. PU hoses: PU hoses have higher working pressure compared to PA and PE hoses. They are used in applications that require higher pressure, such as industrial automation. PE hoses: PE hoses have similar working pressure to PU hoses. They are used in various applications, including the food and medical industries.

Chemical resistance 

PA hoses: PA hoses are resistant to many oils, greases, and organic solvents. PU hoses: PU hoses are resistant to oils, greases, and many chemicals. PE hoses: PE hoses are resistant to many acids, bases, and organic solvents.

Choosing the right pneumatic hose depends on the requirements of the specific application. PA hoses are more suitable for lower pressure applications, PU hoses are flexible and bend-resistant, and PE hoses are lightweight and chemical-resistant. If in doubt, it is always worth consulting with the manufacturer or hose supplier to select the right type of hose for your needs.

Polyethylene hose

What is a polyethylene hose? A polyethylene hose is a flexible line made of polyethylene (PE) – a material with high chemical resistance and good mechanical strength. It is widely used in pneumatic and hydraulic installations as well as media transport systems such as water, air, technical gases, or chemical liquids. Characteristic features of polyethylene hoses: 1) Chemical resistance – polyethylene hoses withstand the effects of acids, bases, salts, and many chemical substances well. 2) Flexibility – compared to polyamide (PA) hoses, they are more flexible and easier to install. 3) Low weight – polyethylene is a lightweight material, which facilitates hose installation and transport. 4) Temperature resistance – the operating range depends on the type of polyethylene (LDPE, HDPE), but these hoses are resistant to moderate temperatures. 5) Good throughput – the smooth internal surface minimizes flow resistance of the medium.

Application of polyethylene hoses

Polyethylene hoses are used in many industries, including: Pneumatics – as lines for compressed air transmission. Low-pressure hydraulics – for transporting liquids in technological installations. Agriculture – in irrigation and fertilizer distribution systems. Food and pharmaceutical industry – in some cases used for transporting water and chemical substances.

Polyethylene vs. Polyamide (PA)

On the Hydron website, you can find polyamide (PA) hoses, which are often an alternative to polyethylene hoses. Key differences: Polyamide (PA) hoses are more resistant to high pressures and temperatures. Polyethylene (PE) hoses are more flexible and resistant to chemicals but have lower mechanical strength. Choosing the right hose depends on the requirements of the specific application. If flexibility and chemical resistance are key, polyethylene hoses may be a better solution. If, however, you need resistance to high pressures and temperatures, it is worth considering the polyamide hoses available in the Hydron offer.

Polyurethane hoses flexible lines for pneumatic installation

Polyurethane hose is one of the more popular types of lines for pneumatic installations used in systems, especially in applications where flexibility, strength, and resistance to various working conditions are required. In the context of polyurethane pneumatic installation lines, polyurethane hoses offer a number of significant advantages that make them popular in industry, automation, or in pneumatic tool power systems. Polyurethane hoses are widely used in pneumatic installations, including compressed air systems that require flexible but durable lines. Due to their lightness, flexibility, and resistance to mechanical damage, these hoses are used in areas such as automation, the automotive industry, or machinery production. In the context of polyurethane pneumatic lines, hoses of this type are excellent in systems that require high abrasion resistance and flexibility while maintaining high working pressure resistance.

Characteristics of polyurethane hoses 

In the context of pneumatic installations, the term polyurethane hoses also frequently appears, which – similar to Tekalan polyamide hoses – are widely used in compressed air systems. Polyurethane (PU) hoses stand out primarily for their high flexibility, resistance to repeated bending, and very good shape memory, thanks to which they return to their original form after deformation. Compared to polyamide hoses, polyurethane hoses are softer and more flexible, which makes them perfect for moving applications, connecting pneumatic tools, manipulators, or elements requiring frequent movement. They are commonly used in workshops, assembly lines, industrial automation, and in installations where freedom of movement of the line is important. Polyurethane hoses also feature good resistance to abrasion, oils, and typical factors occurring in pneumatic installations. Thanks to this, they can be used in demanding operating conditions, maintaining long service life and work reliability. In installation practice, polyurethane and Tekalan polyamide hoses often complement each other. Polyamide hoses are chosen where stiffness, dimensional stability, and resistance to higher pressures matter, while polyurethane hoses are used wherever flexibility and comfort of use are the priority. Proper selection of the hose type allows for optimizing the operation of the entire pneumatic system and adapting it to real working conditions.

Advantages of polyurethane hoses in pneumatics 

• flexibility 
• abrasion resistance 
• chemical resistance 
• temperature resistance 
• safety 

Polyurethane hoses are characterized by high flexibility, which allows them to be easily formed and fitted into difficult spaces. This flexibility makes them ideal for use in installations that require great freedom of movement. Polyurethane is a material resistant to mechanical damage, including abrasion, which ensures the longevity of the hoses, especially in conditions where the lines are exposed to contact with sharp edges or high-friction elements. Polyurethane hoses are also resistant to many chemical substances, allowing them to be used in environments where aggressive chemicals, oils, greases, or other substances may occur. These hoses withstand temperature changes well, both low and high, making them usable in a wide range of temperatures, from -40°C to 80°C. Polyurethane does not contain harmful substances, making polyurethane hoses safe in contact with air used in pneumatic systems, especially in medical or food applications where cleanliness and hygiene are key.
