Technical informations

1. Selection of hoses

In order to correctly select a hose, you should carefully read the characteristics and parameters of a specific product and the operating conditions for which a given hose is to be used.

For more detailed information, e.g. regarding chemical resistance or non‑standard inquiries, please contact our sales department. Tolerance for the parameters contained in this catalog is about 5%. Tolerance for internal hose diameters is no more than 2%. All parameters apply for room temperature (approx. 22°C).

It is possible to make a hose with a non‑standard diameter (not included in the basic offer) and make hoses in color and with a print on a special request.

If you require further information, please contact our sales department.

2. Packaging and transportation

Depending on the type and length, hoses are packed in a straight form or compressed axially or coiled, and then wrapped in stretch foil or other packaging required for transportation. In the case of independent transport, the hoses must be properly secured against mechanical and atmospheric damage.

CAUTION! The standard lengths of the hoses are measured while maximum extension.

3. Storage and operation

To avoid the risk of destruction or damage to purchased hoses, the rules for their proper storage and operation must be observed. The physical properties of plastics change over time and under the influence of atmospheric, temperature, chemical, etc. conditions.

During assembly and operation of the hose you should pay attention to factors which may cause damage or destroy the hose, such as: inadequate bending radius (the bending radius is measured from the inside of the hose), axial torsion and vibration, inadequate operation and ambient temperature, too high pressure/negative pressure and other operating parameters, mechanical damage and other. You should pay special attention when hanging hoses vertically (without suitable supports, the hose may be damaged due to its own weight).

Please contact the sales department for detailed instructions and information. The flow direction of the medium is marked on the hose with an arrow. Reverse assembly will result in faster hose wear and tear. If there is no arrow on the hose, please contact our sales department.

To discharge static electricity, ground the spiral. Instructions on how to properly ground the hose spiral are available from our sales department.
