Technical Details

Quality in all aspects is strongly underlined at Mandals, from reception and control of raw materials, through development and testing of new products, to the production and timely delivery of finished hoses.

We are proud to be ISO 9001 certified, and put great emphasis on fulfilling the criteria set in the specific product certificates relevant to our different hoses. Our product datasheets give end users confidence that the hose will meet their specific need.

Pressure drop in hoses

The flexible lay flat hose will swell in diameter when pressureized, causing a lower pressure drop than compared to a rigid hose. The data is based on internal hose diameter, and the actual pressure drop is therefore some lower. Variables such as fittings and bends increase the frictional losses and an estimate of their effect may be determined by adding an “equivalent length” to the hose length. Values of the equivalent length (Le) may be determined using the internal diameter (D) of the hose in the following relationship:
