Metal Hoses for Industrial Applications

Metal hoses, manufactured from stainless steel or galvanised steel, are a crucial component in industrial applications. They are rust-resistant, heat-resistant (–270 °C to 600 °C), chemical-resistant, and feature excellent pressure resistance (operating pressure from 11 to 150 bar). This makes them ideal for applications across various industries, such as automotive and food processing facilities.

Our metal hoses are not only versatile but also specifically adapted to meet the demands of diverse applications. From cable protection conduits to spiral reinforcements, we offer high-quality solutions for your challenges.

NovaNox® metal hoses with spiral reinforcement for the food industry are particularly easy to clean. The protective hose is self-extinguishing and flexible. In mechanical and plant engineering, as well as in sectors such as shipbuilding and automation technology, they impress with their versatility.

Protective hoses primarily serve cable protection and excel due to their extremely high impact and temperature resistance. Furthermore, they are resistant to liquids such as oil, petrol, or chemicals. With the aid of 2D and 3D models, you can find the correct metal protection hose for your application.

Another innovative option is the PVC-coated metal protection hose, which offers additional resistance to alkalis, acids, and chemicals, without compromising flexibility. For increased pressure, impact, and tensile strength, we recommend the variant with Polycaprolactam (PA6) coating. Our portfolio is rounded off by waterproof metal protection hoses – featuring high pressure, impact, and tensile strength, as well as very high flexibility and a smooth outer jacket that prevents creasing when bent.

NovaNox® offers corrugated metal hoses in various designs, in corrugated and wound versions made from galvanised steel and stainless steel. Strict quality management according to ISO 9001 ensures that every hose is inspected and tested for tightness, cleanliness, and perfect welds.

Corrugated Hose: A thin-walled cylindrical component with a corrugated profile, formed seamlessly or longitudinally welded. As an annular corrugated hose, the profile alignment runs perpendicular to the hose axis – this allows for undisturbed connection of the fitting, prevents torsional stress during pressure surges, and makes the hose highly flexible yet extremely pressure-resistant. High temperature and corrosion resistance complete the profile.

Wound Hoses: Manufactured in a continuous process – by profiling and helically winding a cold-rolled metal strip onto a mandrel tool. Parts of the hose remain displaceable. As a result, wound hoses possess improved flexibility, high mechanical strength, and high elasticity; they are vibration-resistant and extremely durable.

Galvanised steel hoses are versatile in industrial applications thanks to their excellent mechanical protection. They are ideally suited as transfer hoses, suction hoses, or protective hoses made of galvanised steel. Various solids, gaseous media, and liquids can be safely conveyed – as universal exhaust, extraction, and transfer hoses for exhaust gases, smoke, or chips, in heating systems, air conditioning units, ventilation systems, textile and woodworking machinery, chemical industrial plants, agriculture, cable protection, and mechanical engineering.

Strength and Performance: The NovaNox® galvanised annular corrugated hoses are considered all-rounders due to their diverse properties – high tensile and transverse compressive strength, chemical, and thermal resistance. As a protective hose, they shield vulnerable cables from high temperatures, collisions within the installation space, and from oil, petrol, and chemicals. As suction and transfer hoses, they safely convey solids, gaseous media, chemicals, and liquids – even highly abrasive media such as sawdust, granulate, or powders. The galvanised steel hoses withstand temperatures of up to +500 °C.

Construction: A NovaNox® steel hose is constructed entirely from high-quality profiled and galvanised steel. Available as thick or thin-walled, optionally with a seal, according to requirements. The flexible hose is twist-resistant, low-wear, and abrasion-resistant – comprehensive leak testing completes its profile.

Stainless steel hoses are flexible metal hoses, also known as annular corrugated hoses. There are various types such as pressure hoses, vacuum hoses, and versions with straight end pieces or threaded connections. They are flexible, resistant to high temperatures and pressures, and corrosion-resistant – making them a durable, cost-effective solution for industry, sanitary applications, and heating engineering.

Strength and Performance: NovaNox® stainless steel hoses are versatile all-rounders and can be used as suction hoses, transfer hoses, or protective hoses made of stainless steel. As suction and transfer hoses, they safely transport solids, gaseous media, and liquids – even highly abrasive materials such as granulate, sawdust, or powders. As protective hoses, they shield sensitive lines from high temperatures and mechanical stresses. They effortlessly withstand mechanical and thermal loads of up to +650 °C.

Construction: A stainless steel hose is a flexible metallic conduit element. NovaNox® primarily manufactures its stainless steel hoses as corrugated hoses – thin-walled cylindrical components with a corrugated structure in the jacket surface, made from high-quality profiled stainless steel, thick or thin-walled, and optionally with a seal.

Why Corrugated Stainless Steel Hoses? Their corrugated structure makes them flexible and pressure-resistant. NovaNox® annular corrugated hoses made of stainless steel are significantly superior to common spiral corrugated hoses and allow for undisturbed connection of the fitting. They are leak-tight, temperature and corrosion-resistant – ideal for conveying liquids and gases under pressure, as vacuum lines, and as filling hoses.

NovaNox® metal hoses are distinguished by their individual adaptability: a wide range of diameters, wound, braided, and conical designs, as well as materials from steel to galvanised steel to stainless steel. Both simple and complex geometries can be realised in various diameters and lengths.

First, check if the hose has any transport damage. If not, you can cover the hose with a non-conductive material for protection. Ensure contact with welding or flux splashes is avoided. Prevent an electrical short circuit from welding electrodes or earth cables, as this can damage the hose. Furthermore, protect it from heavy contamination – this could impair its flexibility. The thermal insulation should be chosen so that it does not restrict the hose's movement; the insulating material must not contain corrosive components.

When installing, mating fittings must be selected so that the hoses cannot kink at the connections. Ensure sufficient freedom of movement and avoid collisions with nearby components. If the hose is connected directly to a vibrating unit, fix the pipeline immediately after the hose line. To prevent torsional stress during movement, the hose line should be mounted on a single plane.
