Pneuparts

Your machines must continue to run optimally, and we at Pneuparts are happy to contribute to that. From our experience, we notice that the impact of high-temperature compressed air hose on your system is often significant. A standard hose can simply collapse as soon as the air temperature rises too high, which directly affects the performance of your installation.

Together we look for a solution that lasts a long time, so that your machine keeps running and you are not faced with surprises. We are happy to give you expert advice in making the right choice for a heat-resistant hose.

What are heat-resistant compressed air hoses?

A hose that can withstand high temperatures is often made of materials such as silicone, PTFE or EPDM. These raw materials ensure that the hoses retain their shape and strength even when they are suspended in the heat for a long time.

They are highly resistant to ageing, cracking and the action of chemicals. When you work with air, vapor or liquids where the temperature rises considerably, it is smart to always choose a hose that suits your specific application.

Are silicone hoses suitable for extreme heat?

Silicone is without a doubt one of the most heat-resistant materials we use. The material remains flexible and reliable at a high temperature of up to 200 degrees Celsius. Unlike other fabrics, silicone hoses do not become brittle and keep their shape even when you keep heating and cooling down repeatedly within your production process.

When you move air, gas or vapor under a high temperature, these hoses are often the first choice. This is not only due to its excellent heat resistance, but also to the longevity and versatility of the material.

Silicone has excellent properties that prevent the material from hardening or drying out due to heat. Due to these strong properties, silicone hoses are widely applicable and can be seen in a wide variety of industrial processes.

The role of EPDM hoses at high temperatures

In industries such as food, pharmaceutical and chemical industries, EPDM hoses are also used to transport hot water, steam and chemical agents. Because this often happens under a considerable working pressure, it is important that the material can easily handle the combination of heat and force.

In that case, EPDM is an excellent choice for your installation. This material is resistant to high temperatures up to a maximum of 120 degrees, is naturally very flexible and does not age quickly, so it lasts a long time.

EPDM is widely used for hoses that need to be resistant to water and moisture. It is suitable for hot water and steam applications and is flexible and wear-resistant.

In addition, the material offers strong resistance to steam. This makes these hoses ideal for applications where steam plays a major role. In addition, these products are excellent at withstanding aggressive agents and chemicals.

When do you use PTFE hoses?

PTFE hoses are also called Teflon hoses. PTFE is known as polytetrafluoroethylene. Polytetrafluoroethylene is a fluoropolymer. A fluoropolymer is a plastic that contains fluoride, which provides ironclad protection. This makes these materials extremely resistant to aggressive agents such as solvents, acids and bases.

PFTE hoses are resistant to chemicals and can withstand extremely high temperatures, sometimes up to +260°C. These hoses can withstand temperatures from -190°C to +260°C. It is important to stay within this temperature limit for a safe working environment.

Smart choice of materials: go for maximum efficiency

When selecting the right compressed air hose for high-temperature applications, several factors play an important role, including the material and working pressure.

Heat-resistant hoses, such as silicone hoses, are not only resistant to heat up to 200 degrees Celsius, but are also UV-resistant. They are ideal for transporting hot air in industrial processes, automotive applications and other sectors where high temperatures are the order of the day. This maintains performance and longevity even when exposed to sunlight or other forms of ultraviolet radiation without sacrificing performance or longevity.

In addition, the flexibility ensures that they are easy to place in installations with many curves or limited space. By choosing a hose that is designed for your specific application, you are making a sustainable investment in the reliability of your business. Don't forget the inner diameter either: a well-chosen diameter is important for a good flow of air or other media.

In addition to silicone, there are also other materials that allow for a wide range of applications. Polyurethane (PU) hoses are known for their flexibility and are suitable for almost all standard industrial applications with a pneumatic low pressure. For situations in which not only high temperatures, but also aggressive chemicals play a role, PTFE (Teflon) hoses offer a solution. These hoses are designed to withstand both extreme heat and chemical influences, which is why they are widely used in the chemical industry and other demanding sectors.

The manufacture of compressed air hoses is designed to prevent cracking and aging, even with prolonged exposure to high temperatures. In addition, the inner diameter is a factor that you should not forget. A well-chosen diameter ensures a perfect flow of air or other media.

In conclusion, choosing the right compressed air hose for high temperatures requires attention to both the material and the manufacturing. By choosing high-quality hoses that fit exactly to your specific application, you can be sure that your installation will continue to run efficiently.

Which materials suit your specific application?

Choosing the right compressed air hose depends on what flows through the hose. Is it compressed air, or is it also oil and water?

Polyurethane (PU): Ideal for standard use, highly flexible and resistant to kinking. PU hoses can be used up to temperatures of +80°C (polyester) or from -40°C to +60°C (polyether), and remain flexible at low temperatures.
PVC: Versatile and economical, suitable for temperatures between -10°C and +60°C, but becomes stiff and brittle at low temperatures.
Rubber: Rubber hoses have a temperature range of -30°C to +80°C and remain flexible in freezing cold.
Polyamide (Nylon/PA): Polyamide hoses have a higher maximum pressure range, can be used at higher ambient temperatures and are suitable for temperatures from -40°C to +80°C.
Neoprene: Neoprene is sturdy and resistant to hot air, oily vapours and mechanical stress.
Teflon: The king of temperature resistance and chemical resistance.
EPDM: Excellent for hot water and steam applications.
Pneumatic hoses: There are several types of pneumatic hoses, including PU (polyurethane), PA (polyamide), and PE (polyethylene).

It is important to consider the inner diameter and the necessary bends in your installation when making the decision. A hose with a diameter that is too small can lead to pressure loss, which can be detrimental to your production process.

Tips for Maintaining Hoses at High Temperature

Even the best hoses need maintenance. Therefore, check regularly for signs of aging. At high temperatures, rubber or plastic can dry out faster. Also pay attention to discoloration or small cracks at the couplings.

Good ventilation around the compressed air hoses can significantly extend the service life. Our technical specialists can provide you with expert advice to determine the right hose for your situation.

The right compressed air hose for high temperatures

Understanding the impact of compressed air hose temperatures is key to a safe and cost-effective system. Whether you work with silicone hoses for extreme heat or choose a robust heat-resistant hose for industrial use, the right materials make all the difference.

Frequently Asked Questions (FAQ)

What temperature can a standard compressed air hose withstand?

Most standard polyurethane hoses are suitable for temperatures up to about 60 degrees Celsius. However, the air coming out of a compressor can instantly reach exhaust temperatures of 79°C to 95°C.

How does heat affect the working pressure of a hose?

As the temperature rises, the maximum working pressure of a hose decreases. This is because the material becomes softer. Always consult the technical specifications to see which pressure reduction applies to your specific temperature.

Are all heat-resistant hoses also resistant to oil?

No, it depends on the material. EPDM, for example, is very heat-resistant but does not tolerate mineral oils well. Heat-resistant hoses are designed for hot water, chemical cleaning and intensive use in a variety of environments. For oily compressed air at high temperatures, Teflon is often a better choice.
