CHOICE OF FLEXIBLE HOSE SIZE The graph below can be used for the correct choice of the flexible hose. It lets you calculate the tube dimension according to the flow value and speed of the fluid. To find out the dimension of the right hose, draw a straight line connecting the known values of flow and speed. The intersection of this line on the middle of the picture determines the value of the diameter of the hose to be chosen. In case the value found does not correspond with one of the diameters DN indicated, the highest value must be chosen. Use the speeds suggested for intake and return pressure...

ASSEMBLY INSTRUCTIONS FOR FLEXIBLE HOSE FITTINGS FITTINGS FOR FLEXIBLE HOSES WITHOUT EXTERNAL PEELING - STANDARD SERIES 1. Cut the hose at the desired length at a right angle with the specific disc cutter. Remove any cutting residues from the hose edge (Fig.1). 2. Insert the sleeve on the hose until it stops (Fig.3). 3. Insert the stud of the fitting into the hose until the same fitting comes into contact with the sleeve (Fig.4). 4. Press the sleeve on the hose with the suitable clamps following the directions in the pressing tables (Fig.5). 5. It is imperative to check the collapse of the fitting...

PRESCRIPTIONS FOR THE INSTALLATION OF FLEXIBLE HOSES ACCORDING TO DIN 20066 To ensure the efficiency, safety and duration of the flexible hoses and related fittings it is necessary not to exceed the admitted working pressures and maximum temperatures, assemble the hoses correctly, use the most suitable fittings based on the assembly conditions, determine the length of the hoses in consideration of their movement, if any. Therefore, the correct installation of the assembled flexible hoses requires the compliance with the prescriptions described below. 1. Do not apply torques to the flexible hoses...
