Metal hoses

Metal Hoses

These hoses are constructed from a stainless steel band. They are rolled into the shape of a tube and butt welded longitudinally. Then the tubes are mechanically or hydraulically deformed into spiral or parallel corrugated hoses. These are the two basic shapes of corrugated metal hoses.

The flexibility of the hoses is determined by the overall wave configuration, viz:

Large wave height: flexibility increases with higher wave height.
Small wave spacing, many waves per linear meter.
The flexibility is proportional to the number of waves per unit.
The wall thickness: a thinner wall gives great flexibility but at the expense of the compressive strength of the hose.
The waveform: an omega shape gives greater flexibility than the more straight shape.

The great advantage of the parallel corrugated hoses is, that they are not subject to torsional forces created by pressure, pressure shocks and pulsations.

Two types

In both types, the distance between two waves can be large or small,

so that one speaks of widely or narrowly corrugated hoses. The pressure resistance of a hose is determined by the stainless steel braid. The number of braids varies from 1 to 3. However, the braid also absorbs the reaction force created by the internal pressure. The number of braids determines the maximum internal working pressure of the hoses, as well as the test and burst pressure. The safety factor is applied between working pressure and burst pressure and is 4.
