Applications and Advantages of a PTFE Conductive Hose

PTFEconductive 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 a low conductivity medium which might be charged.

Why should you Select a PTFE conductive hose?
