What Is a PTFE Chemical Hose?

A PTFE chemical hose uses polytetrafluoroethylene as the fluid-contact inner layer. PTFE is widely used in demanding industrial applications where high chemical resistance and a wide operating temperature range are required.

The CHEM TEFLON hose combines a PTFE inner tube with textile reinforcement, steel wire spirals, flexible copper wires, and an EPDM outer cover.

This construction makes the hose suitable for selected chemical transfer and industrial process applications when the chemical and operating conditions are compatible with the product specifications.

Chemical Hose Applications

Chemical transfer hoses are used in industrial systems where liquids and process media must be transferred safely between equipment.

Typical applications include:

Chemical processing plants
Chemical manufacturing
Chemical transfer systems
Process equipment
Chemical filling and unloading
Tank and tanker transfer
Industrial process lines
Pharmaceutical applications
Biotechnology applications
Sanitary process systems
Industrial fluid transfer

The hose should always be selected based on the specific chemical, concentration, temperature, pressure, and duration of contact.

Chemical Resistant Hose Construction

PTFE Inner Tube

The PTFE inner tube provides the fluid-contact surface for applications requiring a high level of chemical resistance.

Reinforcement

The hose incorporates synthetic textile reinforcement, zinc-coated steel wire spirals, and flexible copper wires to provide mechanical support and flexibility.

EPDM Outer Cover

The smooth EPDM outer cover provides resistance to abrasion, aging, and ozone. This construction is intended for demanding industrial environments.

How to Choose a Chemical Transfer Hose

Choosing a chemical transfer hose requires a detailed review of the application.

Chemical Compatibility

The most important consideration is compatibility between the hose's wetted materials and the chemical being transferred.

The chemical name alone may not be sufficient. Concentration, temperature, pressure, and exposure time can affect material compatibility.

Operating Pressure

The hose's working pressure must be suitable for the maximum pressure of the system.

The CHEM TEFLON range provides working pressure ratings of up to 16 bar / approximately 232 psi, depending on hose size.

Temperature

Temperature can significantly affect hose performance and chemical compatibility.

The specified operating temperature range for CHEM TEFLON is -40°C to +150°C (-40°F to +302°F).

Vacuum

Vacuum capability is important in suction, unloading, and process applications.

The CHEM TEFLON series is specified with a vacuum resistance of 675 mmHg / 26.6 inHg.

Bend Radius

The hose must not be installed below its specified minimum bend radius. Excessive bending can damage the reinforcement structure and reduce service life.

PTFE Chemical Hose Advantages

PTFE is widely selected for demanding chemical applications because of its resistance to many aggressive media and its broad temperature capability.

Potential advantages of a PTFE-lined chemical hose include:

High chemical resistance
Wide temperature range
Smooth fluid-contact surface
Suitable for demanding process applications
Suitable options for high-purity applications
Easy-to-clean internal surface characteristics

However, PTFE should not be considered universally compatible with every chemical. Chemical compatibility must be verified for the specific application.

Chemical Hose Safety and Installation

Chemical transfer systems require proper hose selection, compatible fittings, correct installation, and regular inspection.

Before installation:

Verify chemical compatibility.
Confirm the maximum operating pressure.
Confirm the operating temperature.
Check the hose minimum bend radius.
Use compatible fittings and couplings.
Inspect the hose for visible damage.
Avoid excessive twisting and bending.
Replace damaged or severely worn hoses.
Verify the complete system before introducing the chemical.

For hazardous or aggressive chemicals, the complete transfer system should be reviewed by qualified personnel before operation.

FDA, USP and Sanitary Applications

The CHEM TEFLON product information specifies:

FDA CFR 21 §177.2600
USP Class VI
ISO 10993 Parts 5, 10 and 11:2009
3-A Sanitary Standard Class II

These specifications can be relevant for selected pharmaceutical, sanitary, food-related, and process applications. The specific regulatory requirements of the final application should always be verified before installation.
