Hoses

In the chemical and petrochemical industries, products are transported via ship, rail tank cars, tank trailers, tank containers, and intermediate bulk containers (IBCs). We have developed specific hose qualities to meet the unique requirements of these various media and transport processes.

The chemical industry processes and transports a vast array of media. Hose lines for these applications must withstand highly aggressive chemicals, such as acids and alkalis. The same durability requirements apply to the fittings. Markert Marsoflex offers a broad selection of liner materials to accommodate different media.

Almost all industrial applications require operating materials like nitrogen, steam, water, and air. "Service hoses" (or operating material hoses) are used to transport these media.

Processes in the pharmaceutical, biochemical, and general chemical industries – as well as the media used for cleaning and sterilization – require excellent chemical resistance. Fluoroplastics are typically the primary choice for liners in these applications.

Hose lines are universally used in the food industry – from milk processing and fermentation in breweries and wineries to juice filling, high-proof alcohol production, and powdered food processing.

Various hose lines are used throughout the upstream, midstream, and downstream processes of the pharmaceutical and biochemical industries, including applications such as fermentation, bioreaction, and filling. The primary focus is always on biocompatibility, cleanability, and pharmaceutical compliance.

Composite hoses offer exceptional flexibility and mechanical strength – even at low temperatures – due to their layered film construction. They are ideal where ease of handling is prioritized, such as during the loading and transfer of mineral oil products.

Metal hoses are frequently used in industrial applications involving extreme temperatures. In addition, they can be provided with specific wall thicknesses, material qualities, and braided reinforcements to achieve very high operating pressures. Metal convoluted hoses are available in various designs.

Beyond standard applications, we offer customized hose solutions for specialized areas such as breathing air supply, fire extinguishing, peristalsis of abrasive media, and hose systems with monitoring functions (double hoses) or heating/cooling functions.

The service life of hose lines depends heavily on handling, storage, and operating conditions. Harsh conditions include:

• Abrasion on the floor and other surfaces
• Kinking
• Falling below the minimum bending radius, high bending cycles
• Frequent pressure and load changes
• Torsion
• Excessive temperature stress
