EFLEX
Is Available in Many Sizes
Ranging from 30 Ø to 150 Ø
Ready to Be Delivered upon Request |
|

The standard
dimensions of EFLEX are as shown in the table below. A pilot
wire is provided inside EFLEX in the course of its production.
It is connected with the cable pilot wire to pull the cable
in to the pipe. EFLEX is, as a rule, shipped from the factory,
wound in a coil. A pilot wire has an allowable tensile strenght
of 50 kg. |

•
When purchasing EFLEX, it is recommended that its nominal
diameter be more that 1.5 times as large as the outer
diameter of the cable to be accommodated.
• Dimensions other than the above standards are
acceptable, but requests for longer dimensions cannot
always be met due to transportation considerations.

PROPERTIES
OF EFLEX |
|
| |
•Product Characteristics
Tensile Strength
When EFLEX, both ends of which have been specially processed
with terminals, is stretched axially, it displays tensile strengths
for different sizes as shown in the right Figure. When released
from an approximately 40% elongation, EFLEX returns to its original
state without retaining any permanent strain. In addition, its
joints demonstrate the same strength as its main body.
|
 |
| |
•Flat-compression Characteristics
When compressed between two parallel plates as shown in the
sketch below, EFLEX
displays the relationship between load and elongation according
to size as shown in the right Figure.
 |
 |
| |
•Load-withstanding Strength
For this, EFLEX was buried 1.2 m under the ground and was run
over by a truck. The flattening deformation was measured that
EFLEX was scarcely affected, demonstrating sufficient strength.
