Metal hoses for extreme conditions

The materials used for metal hoses make them extremely resistant to corrosion and abrasion. Their excellent temperature tolerance, strength under vacuum and outstandingly low permeability make metal hoses the preferred choice for transporting solid, liquid and gaseous substances under particularly demanding conditions. HANSA‑FLEX offers comprehensive advice on the selection of the best metal hose solution.

The highest quality and reliability with HANSA‑FLEX

High-quality materials and professional workmanship

First-class corrugated hoses in stainless steel form the basis for the quality of metal hoses from HANSA‑FLEX. However, it is only the certified assembly processes at the hands of trained personnel that turn them into truly robust hose lines. Using the latest methods, we do not limit testing to one-off items only; we also test up to 100 % of series-produced components for leaks.

  • Highest standards of quality and precision
  • Certified assembly processes
  • 100 % leakage testing

The most suitable fitting for every situation

Metal hose lines are used widely, not least because of their wide temperature range, high strength under vacuum and availability in many different sizes. As well as acids and alkalis, they can also transport hot liquids or gases.

  • Wide temperature range of -196 °C to +550 °C
  • Suitable for pressures up to 300 bar and vacuum
  • Nominal diameters from DN 6 to DN 250 mm

Top-class metal hoses from the fluid specialists

High temperature tolerance and resistance to aggressive media lie behind the excellent performance characteristics of HANSA‑FLEX metal hoses.

  • Parallel corrugation construction for high performance
  • Different constructions (single and double-walled)
  • Longitudinally welded
  • Various hose materials, e.g. stainless steel 1.4404
  • Braid reinforcement, e.g. stainless steel 1.4301
  • Components designed to work together perfectly

Use in potentially troublesome and safety-relevant areas

As you would expect, HANSA‑FLEX fulfils the requirements of standards DIN EN ISO 9001 (quality management) and DIN EN ISO 14001 (environmental management).

The HANSA‑FLEX production facility for metal hoses has the necessary approval for metal hose line welding in accordance with DIN EN ISO 15085-2 CL 1 and the manufacture of preassembled components in accordance with the Pressure Equipment Directive 2014/68/EU (PED).

The use of hose lines manufactured from non-rusting steels ensures the highest resistance against chemical substances. Being welded in accordance with DIN EN ISO 3834-2, they provide safe connections, even under extreme conditions.

Numerous type approvals in accordance with DNV, ABS, BV, LR and Rina and manufacturer qualification through DNV in accordance with DIN 2303 ensure problem-free operation of our products in industries with especially high requirements.

Metal hose line manufacture

Due to their large temperature range, high stability under mechanical loads and low permeability, metal hoses from HANSA‑FLEX perform extremely well in numerous applications. Certified assembly processes, up-to-date test methods and comprehensive cleaning procedures ensure the best quality and high levels of safety for people and the environment. Crucial factors in the use of metal hoses in potentially troublesome or problematic production areas. HANSA‑FLEX can manufacture hose lines to meet the customer’s specific requirements as one-off items or in series production. Digitally supported processes ensure not only consistently high quality but also excellent availability.
