High-Performance Teflon Corrugated Hose with Stainless Steel Flanges for Chemical & Industrial Systems

Virgin PTFE Bellows | Extreme Temperature Resistance | Corrosion-Proof Fluid Transfer Hose

Engineered for the most demanding processing environments, the Teflon Corrugated Hose delivers outstanding flexibility and chemical durability. Manufactured using 100% virgin PTFE and equipped with precision-machined stainless steel flanges, this hose ensures safe, stable, and contamination-free transfer of aggressive or high-purity fluids.

Overview – A Durable Flexible Connector for Harsh Chemical Environments

When pipelines experience vibration, movement, or thermal cycling, rigid metal hoses often fail. Our Teflon corrugated hose solves this by providing:

• Superior flexibility from PTFE bellows

• High fatigue resistance under continuous vibration

• Universal corrosion resistance to nearly all industrial chemicals

It is ideal for pumps, dosing systems, reactors, compressors, filling lines, and high-purity transfer applications.

Temperature capability: -70°C to +260°C

Main Advantages of Teflon Corrugated Hose

• Exceptional Flexibility
  The helical PTFE bellows allow repeated bending, reducing stress at connection points.

• Inert & Non-Contaminating
  PTFE does not react with chemicals, making it suitable for pharmaceuticals and food production.

• Excellent Thermal Endurance
  Maintains mechanical integrity across extreme temperatures.

• Anti-Adhesion Inner Wall
  Fluids do not stick, reducing cross-contamination and cleaning time.

• Precision Stainless Steel Flanges
  SS304/316 ensure corrosion-proof performance and easy installation.

• RoHS Compliant
  Meets global environmental and safety regulations.

Design & Construction Details

• Hose Body Material: 100% Virgin PTFE

• Bellows Geometry: Helically corrugated for optimized flexibility

• Flanges: SS304, SS316, SS316L

• Type: Fixed flange or floating/lap joint flange

• Optional Reinforcement: Stainless steel wire braiding for higher pressure applications

This construction ensures long-term reliability even in highly corrosive media.

Technical Parameters

Chemical Resistance & Clean Transfer Capability

PTFE’s inert molecular structure allows it to withstand:

• Concentrated acids

• Chlorinated solvents

• Caustic solutions

• Organic chemicals

• Ultra-pure water

Its non-stick surface minimizes residue and prevents contamination—critical for pharmaceutical and food applications.

Typical Usage Scenarios

• Chemical Plants: Transfer of corrosive liquids

• Pharmaceutical Systems: High-purity media pipelines

• Food Processing: CIP/SIP compatible fluid handling

• Water Treatment Plants: Dosing and aggressive effluent systems

• Industrial Equipment: Flexible connections for pumps and compressors

• Pipeline Engineering: Compensation for misalignment and thermal expansion

Movement, Vibration & Expansion Control

The corrugated PTFE structure absorbs:

• Vibrations from rotating machinery

• Axial or lateral displacement

• Thermal expansion cycles

This prolongs equipment life and reduces downtime caused by piping fatigue or failure.

Flange Standards & Custom Options

Available standards:

• ANSI 150 / 300

• JIS 10K

• DIN PN16 / PN25

Custom flange drilling, lengths, diameters, and reinforcement layers can be produced according to project needs.

Quality Testing & Inspection

Before shipping, each hose undergoes:

• Detailed visual inspection

• Dimensional accuracy verification

• Hydrostatic pressure testing

• Optional SGS/CTI third-party testing

We ensure every assembly meets strict international quality requirements.
