Materials:
As flexible conduits they often have to operate elastically under extreme conditions and, because of the thin walls as compared with rigid piping, they must be especially corrosion resistant.
Moreover, these hoses have to meet the following requirements:
good cold forming properties,
good strenght properties,
optimal thermal stability,
good corrosion resistance,
high reliability in operation.
In principle, there is no material which will ideally meet all these domands. The materials, used for our range, cover a larqe variety of needs occuring in practice. Our standard materials are indicated for each type of hoses.
