WHY DOUBLE WIRE CLAMPS?
YDNAC hose clamps are made of double strand steel wire with high resistance; they are coated with a preservative zinc coating which ensures a practically unlimited durability.
In comparison with other clamps they have the following advantages:
The stress on the plastic or rubber hose caused by the double strand EMWARD clamps is obviously lower - though the clamping action is the same - than the one caused by single wire clamps; in fact, the radial load is distributed over a wider surface of the hose (see picture A and B). Furthermore, the roundness of wire of which the EMWARD clamps are made allows the cutting action, when compared with the one produced by the regular boot clamps (see pictures A and C), to be much lower. It ensures a longer durability of the flexible hoses and a higher resistance of blow-off.
GENERAL SPECIFICATION FOR YDNAC HOSE CLAMPS
DIMENSIONAL CONTROL
When the clamp is fitted over a tool gauge of dia. + B, the lengths of the two ends must be one minus or equal to R, the other major or equal to R2.
Owing to the oval shape of the clip, the test has to be made with a plug gauge with four diameters A, B, C, D - decreasing - whose values are shown on the table.
The following points must be observed:
-
The clip, when opened at its maximum, must be able to run easily over the dia. 'A'.
-
The clip, after being expanded to dia. 'A', must fit, with a good roundness, over the dia. 'B' & 'C'.
-
The condition of good roundness is ascertained if, between the clip and the gauge, no cylindrical feeler (calibrated wire) of a prescribed diameter 'X' passes.
In order to ascertain that permanent set suffered by material after the assembly be within the prescribed limits for the best working of the clip - this will be fitted on the dia. 'A' of gauge; then (in free condition) the clip must not pass over dia. 'D' (no-go) of the gauge.
PRESERVATIVE COATING
The clips are coated, through the electrolytic process with ZINC, thick >8µ as per specs. UNI 4721 (ASTM: A 164-55).
Resistance to corrosion is to be checked in a chamber with salt spray (5% Na CI) as per specs. UNI 5687-65 (ASTM: B 117-64).
The minimum time of exposure to salt spray before rust marks are apparent is 48 hours.
COLOUR CODING
The clips have a colour coding for identification of size, corresponding to the one shown on the inside table.
