Wiring harnesses, gases, brake fluids, gasoline, water, chemicals, bulk materials, even concrete - there is hardly a material in the world that cannot be transported in hoses.
The plastics we use to manufacture them are as varied and yet unique as their areas of application. Find out here how we at Sattler can help you plan, develop and implement the perfect hose solution for your application.
Hoses have been used to transport gaseous, solid or liquid substances since ancient times. In the past, hoses were usually made of natural materials, but today high-quality plastics are used. Their chemical, physical and mechanical properties precisely match the hose's intended application.
In addition to being used as a transport line, hoses can also be used for electrical or thermal insulation.
Our goal is to manufacture individual hose solutions. Nevertheless, hoses can be divided into different types depending on the application or material.
Suction hoses are used to extract liquids or gases. The sometimes considerable pressure differences between the inside and outside of the hose place special demands on the hose material. It must be designed in such a way that the suction hose does not collapse under any circumstances..
Modern vehicles contain several kilometers of electrical cables, which are bundled together in cable harnesses for a better overview. This is where cable cover hoses come into play. They protect the cable harness from moisture and mechanical stress.
Thermoplastic elastomers (TPE) are plastics that exhibit the behavior of classic elastomers at room temperature, but can be deformed like thermoplastics under heat. These special plastics can be used to produce TPE hoses for the chemical and food industries.
The task of these hoses is similar to that of cable covering hoses. They are used to protect and bundle electrical cables. Cable protection conduits can be used outdoors and indoors and are made of a variety of different materials.
The abbreviation LABS stands for "paint wetting impairment substances". LABS-free hoses are therefore used primarily in paint stores to avoid visible defects on the painted product.
Perfect paint application requires not only LABS-free paint lines, but also all relevant components. Therefore, electrical supply lines must also be bundled in LABS-free cable cover and cable protection hoses.
A bag filter is a device for the physical separation of solid-liquid mixtures or contaminated gases. In this filtration method, the filter medium is formed into a tube. This allows high throughput rates while maintaining a cost-effective and compact design.
Hose lines are stationary hoses for transporting materials. They are used wherever fixed pipes can only be installed with disproportionate effort, or if a certain flexibility is still desired despite stationary installation.
When asked about the typical hose, most people will certainly think of the garden hose first. Athletes might think of the bicycle hose, motorcyclists and car drivers might think of the gasoline hose. It is impossible to imagine our lives without such hoses.
Nevertheless, and this is often forgotten, these typical hoses are also highly developed specialists. Fuel hoses, for example, absolutely must be made of weather-resistant plastics that are chemically inert to solvents and organic compounds.
And even with an everyday product like the garden hose, weather resistance is an issue. After all, such a hose must withstand extreme temperature fluctuations over the course of the year and also absorb large amounts of UV light without becoming brittle.
Also, no one can use bicycle inner tubes that "no longer hold the air", that is, are no longer gas-tight.
Therefore, for us at Sattler, every hose is a typical hose, perfectly adapted to its field of application and made of high-quality raw materials.
The raw materials from which hoses are made are just as diverse as their areas of application. Modern hoses are usually made of plastics such as TPE, PE, PUR or PA.
As plastics specialists, we have many years of experience and a wealth of knowledge about the chemical, physical and mechanical properties of high-quality plastics. This enables us to realize highly specialized solutions. For special applications, glass fibers, metal or natural fibers are also used.
The material from which we manufacture a hose depends not only on factors such as cost-effectiveness and availability, but above all on the intended use. For example, a hose for outdoor use must be made of weather-resistant plastic. Strong sunlight, moisture and strong temperature fluctuations must not damage the material.
Hoses for the chemical industry must be chemically resistant to the substances they transport. For example, plastics that come into contact with acids and alkalis have to meet different requirements than hoses used in the petrochemical industry. The latter must above all be inert to oils and organic solvents.
Hoses that come into contact with food are subject to special legal regulations. They must be made of food-safe materials that cannot release any substances that are harmful to health. TPE and silicones in particular are very much in demand here.
Various processes are used to manufacture hoses. The most important are:
Among these processes, extrusion is the most commonly used. In this process, the desired plastic or a mixture of different plastics is heated until it liquefies and then formed into the desired shape via a die.
This process also makes it possible to produce coated hoses. Large-lumen hoses are extruded as plastic webs, the edges of which are then welded or vulcanized to form the finished hose in a second step.
Very long hoses can be realized by extrusion over a mandrel with the desired diameter.
Hoses are used in numerous branches of industry and commerce. In addition to the chemical industry, the automotive and food industries are among the main customers for hoses.
In vehicles, hoses are used to transport fuels and operating fluids. In addition to gasoline, these include radiator fluid, oil and lubricants, and washer water for the front and rear windshields..
Each of these hoses has to withstand the highest stresses and transport chemically very reactive substances in some cases. This places special demands on the plastics used.
Particularly strict hygiene regulations apply to food processing. All equipment and machines that come into contact with food must be food-safe.
They must therefore not undergo any chemical reaction with the food or even release any harmful substances. Only particularly high-quality plastics are therefore suitable for these tubes.
A wide variety of requirements are placed on hoses in chemical plants. The exact profile here depends on the intended use.
Resistance to hot liquids can play a role in these hoses, as can acid resistance or insolubility in organic solvents.
The cost of hoses is as individual as their intended use. At Sattler, our goal is to provide you with the highest quality at the best possible prices at all times. That's why we always prepare an individual offer based on your wishes and requirements.
As specialists in high-quality plastics, we have many years of experience and extensive knowledge of these unique materials. Therefore, we are happy to assist you in planning and realizing your projects.
