| Shapes and Sizes |
| |
| KPC's vast range of different flexible
conduits is available in diameters from 2.75mm to 350 mm. Hoses
are available either in random lengths or in standard coils of 10,
15, 20 or 30 meters. Hoses can also be cut to the customers specific
requirements. KPC Flexi Tubes has the unique advantage of offering
a large part of its product range on spools in continual long lengths.
Some aspects of strip wound hoses are described below to assist
in choosing the right product. |
| |
| A basic distinction can be
made between two types: |
| |
| Double interlocked Profile |
| |
| The double interlocked profile
is designed to meet the highest demands that comply with tensile
and bending strength, compression and impact resistance against
all mechanical stresses |
 |
|
| |
| Square Lock/ Lay on Profile |
| |
The square lock profile is designed
for metal hoses which have to withstand negligible requirements.
Another distinction can be made between Polygonal and Round
Sections:s |
|
|
| |
| Size Tolerance |
| |
| When a Round Strip Wound Hose
is cut into short lengths, it has a tendency to change its
diameter slightly, producing a "Big End" and a "Small
End". A Polygonal Hose does not change its diameter when
cut. Therefore, if a precise and constant size is required,
polygonal Hose should be specified. Round Hoses may be used
where size tolerances are greater. |

| Exhaust Gas Leakage Rate |
| |
Round Exhaust Hoses usually
incorporate copper wire packing or cotton yarn packing to
control the rate of gas leakage. Packing is not required in
a Polygonal Hose which will usually have lower gas leakage
rates than a round hose without packing in a typical exhaust
application. However, in case of solid or liquid Handling
applications, a Round Hose with packing is preferred.
(Note: Where zero gas leakage is required, a KPC Corrugated
Metallic Hose should be specified). |
