Anti-Static PTFE Hose Solutions for Flammable Liquids and Static-Sensitive Processes

Introduction

An anti-static PTFE hose is designed for fluid-transfer systems where friction between the transferred medium and the hose wall may generate electrostatic charge.

Static accumulation can be a significant consideration when transferring fuels, solvents, flammable liquids, chemical media or materials used in static-sensitive coating processes.

Shenzhen Jingcheng High-tech offers several anti-static PTFE hose constructions to meet different requirements for internal cleanliness, flexibility, bending radius and electrical performance.

The available series includes:

• Anti-static smooth-bore PTFE hose

• Anti-static corrugated PTFE hose

• Anti-static inner-smooth outer-corrugated PTFE hose

• All-black conductive corrugated PTFE hose

Why Static Control Matters

Electrostatic charge may be generated by:

• High fluid velocity

• Low-conductivity liquids

• Fuel and solvent transfer

• Particle-containing media

• Repeated hose movement

• Dry ambient conditions

• Friction between the medium and the PTFE surface

Uncontrolled static accumulation may create:

• Electrical discharge

• Process instability

• Interference with sensitive equipment

• Potential ignition risk around flammable media

• Safety concerns during fuel or solvent transfer

An anti-static hose helps provide a controlled path for charge dissipation when the complete assembly is correctly designed and grounded.

The hose must be considered together with conductive fittings, electrical continuity and the equipment grounding system.

Available Hose Structures

1. Anti-Static Smooth-Bore PTFE Hose

The smooth internal surface provides:

• Low flow resistance

• Reduced material retention

• Easier cleaning

• Stable transfer of compatible liquids

• Better suitability for clean fluid systems

This construction is appropriate when low residue and smooth flow are primary requirements.

2. Anti-Static Corrugated PTFE Hose

The corrugated structure provides:

• Greater flexibility

• Smaller bending radius

• Easier installation in compact equipment

• Better accommodation of movement and vibration

It is suitable for systems requiring flexible routing.

3. Anti-Static Inner-Smooth Outer-Corrugated PTFE Hose

This construction combines:

• Smooth product-contact inner wall

• Flexible corrugated outer structure

• Reduced internal residue

• Easier cleaning

• Small bending radius

• Anti-static performance

It is suitable for applications requiring both clean transfer and flexible installation.

4. All-Black Conductive Corrugated PTFE Hose

The all-black conductive configuration is intended for applications requiring stronger static-dissipation performance and high flexibility.

The required hose resistance, electrical continuity and grounding method must be confirmed before production.

Key Features

High- and Low-Temperature Performance

The catalog indicates an approximate temperature range of:

-60°C to +260°C

The final range depends on the selected hose structure, reinforcement and fittings.

Low Friction

The catalog describes a low friction coefficient of approximately 0.1, supporting efficient fluid transfer and reduced material adhesion.

Wear Resistance

The smooth PTFE surface provides low adhesion and can support suitable wear performance in fluid-transfer applications.

Lightweight Construction

PTFE hose structures are relatively lightweight and suitable for a wide range of equipment systems.

Shock and Impact Resistance

The flexible construction can help accommodate movement, vibration and moderate mechanical impact.

Static-Control Capability

The anti-static formulation is intended to reduce electrostatic charge accumulation during transfer.

Chemical Resistance

The hose can be evaluated for many compatible:

• Acids

• Alkalis

• Solvents

• Fuels

• Oils

• Corrosive chemicals

• Flammable liquids

Catalog Electrical Information

The catalog also states a dielectric withstand range of approximately 50–120 kV.

Because anti-static performance and dielectric insulation are different electrical requirements, the applicable resistance, conductivity and voltage parameters should be confirmed for the exact hose formulation before publishing them as final technical specifications.

Typical Applications

• Chemical-liquid processing

• Flammable-liquid transportation

• Fuel and solvent conveying

• Static-sensitive coating equipment

• Paint-production machinery

• Chemical dosing systems

• Laboratory chemical transfer

• Food-processing equipment

• Corrosive fluid pipelines

• Industrial process systems

• Hazardous-media transfer

• Customized static-control equipment
