Preassembled hose lines, ready to install

After determining the cutting dimension, we cut the hydraulic hose to the correct length using dedicated hose-cutting machines. Then we peel the hose to achieve the required skive length for the chosen attachment method and check the result for the correct nipple constriction.

Every hose is dry cleaned immediately after cutting, before any foreign material has had chance to cool and firmly adhere. The projectile is shot under high pressure through the entire length of the hose from both ends. This removes all loose and fine particles of dirt from inside the hose.

After pushing on a steel or stainless steel fitting correctly dimensioned for the hose, we crimp the fitting onto the hose. We use various hose crimping devices depending on the hose type and hose size. Finally we check that the crimping has been successful by comparison with the dimensions in our crimping dimension charts.

Each of our HANSA‑FLEX preassembled hose lines is given a unique and durable marking using the alphanumeric X-CODE system. This enables hose lines to be reliably identified and simplifies reordering anywhere in the world.

In main quality assurance facilities in Bremen, we check all components such as hoses and fittings. Each individual step in the preassembly process follows our defined rules. This ensures we maintain the same high quality for all our hose lines anywhere in the world.

Challenging applications such as the defence, maritime and mining industries demand the use of certified hose lines. In addition to the HANSA‑FLEX GVZ production workshop in Hamburg, some branches can preassemble hose lines in accordance with requirements of DNV, MED, Bureau Veritas and many other classifications.

On request, we also install the appropriate protection devices and safety equipment directly onto your hydraulic hose lines. By having suitable protection against rubbing, heat or kinking installed, you avoid premature wear on your hydraulic hose lines, while protecting people and the environment.

As operating equipment contaminated by oil, hydraulic hoses pose a risk to the environment. Transport and recycling are therefore subject to strict requirements. Working with a certified waste management company, we ensure their professional disposal, including temporary safe storage in tested collection containers.

Hydraulic hose lines must be professionally inspected by officially authorised persons every 12 months after being brought into first use. Our experts perform the prescribed visual inspections and function tests in accordance with the requirements of DGUV, BetrSichV and the EU Directive on Equipment Safety 2009/104/EC.
