PTFE
conductive hose is equipped with anti-static
properties. A PTFE hose has different
thickness levels complete with a protective braiding on it, known as PTFE braided hose.
The special feature of a PTFE conductive hose is that the inner liner is made up of a
resilient material which avoids static build up as seen in normal hoses. The
PTFE is thus considered to be the safer option of the two as static buildups have certain consequences in the form of sudden
explosions.
For single phase mediums, a PTFE conductive hose
with its electrical conductivity being less than 10,000 pS/m, is a
prerequisite.
A PTFE conducive hose is especially useful in the case of a mixture of liquids
such as liquid and gas or solid particles in a liquid.
Mediums such as clean pure gases do not
require a PTFE conductive hose.
The flow velocities of different fluids
impact the electrostatic charging or discharging. That is why it is imperative
that the flow velocity of hoses should be
controlled. There are norms in chemical plants that suggests the flow velocity limit to be below 7 m/s for fluids,
especially the once with low conductivity, or to be more precise for fluids
that have highly static properties. But in cases where it cannot be controlled,
such as in the case of two-phase mediums, it would lead to a high electrostatic
charge while it flows through the hose.
This situation triggers a rub-on effect on
the hose which in the eventuality of also getting charged and that has a
polarity right opposite to that of the medium that passes through it can offset a serious damage and the eventuality of
an explosion cannot be ruled out. Hence, in conditions like this, the only hose that passes muster is the
PTFE conductive hose, as the hose instead of getting charged stays neutral.
This situation holds true even in the
case of carrying low conductivity medium
which might be charged.
Why
should you Select a PTFE conductive hose?
Heat
Resistance:
·
A PTFE hose can be used even in
an extreme temperature range such as -260 degrees Celsius to 260 degrees
Celsius.
·
It is resilient even when it
undergoes abrupt cooling or heating.
·
It is a good insulator with the
melting point standing at 327 degrees Celsius.
·
The above point makes it
conducive to easy fluid transfer under extreme temperatures and pressures.
Di-Electric
Strength:
·
It works between the range of
50-120 Kilovolts per mm
·
The above property helps in the
insulation procedure involving electric cables.
Reduction
in Friction:
·
The
friction coefficient equals to 0.1.
·
It has identical static and
dynamic coefficients.
Corrosion
Resistivity
·
It is chemically inert.
·
It does not absorb water
·
The above property helps in
transferring chemicals and metal parts protection.
Applications
