Non-Metallic Expansion Joint

A professional manufacturer of non-metallic expansion joints and high-temperature fabric solutions, serving global industries with reliable, cost-effective designs.

🚀 Why Choose Vetex Expansion Joints

Designed for extreme industrial environments where metal fails
  • Multi-directional movement absorption Handles axial, lateral, and angular displacement simultaneously (3–5× metal joints)
  • Zero thrust force No reactive force → simplifies pipe support design → reduces project cost
  • High temperature resistance Up to 1000°C+ with ceramic fiber composites
  • Corrosion resistant Suitable for SO₂, acid gas, alkaline exhaust
  • Vibration & noise reduction Ideal for fans, blowers, and pumps
  • Lightweight & easy installation Faster installation, lower labor cost

🧱 Structure Overview (Multi-Layer Composite Design)





From gas side to outer layer:
  1. Inner Liner (Optional) Stainless steel mesh / baffle → protects insulation & improves flow
  1. Sealing Layer (Core)
  • Silicone-coated fiberglass
  • Fluoroelastomer (FKM)
  • PTFE membrane
  1. Thermal Insulation Layer Ceramic fiber/fiberglass blanket
  1. Insulation Packing Enhances thermal & airtight performance
  1. Outer Protective Layer Weatherproof & mechanical protection
  1. Metal Frame / Flange Carbon steel or stainless steel

🎯 Customization

All products are 100% custom-made
We support:
  • Custom size & shape
  • Multi-layer material design
  • High-temp / anti-corrosion solutions
  • Special reinforcement for negative pressure

⚠️ Important Notes

  • Not suitable for high-pressure pipelines
  • Avoid sharp object damage during installation
  • Outdoor use requires UV & rain protection

🧠 How to Select the Right Model

We recommend confirming:
  1. Operating Temperature
  1. Gas Composition (SO₂, dust, corrosive media)
  1. Pressure condition (positive/negative)
  1. Movement values (axial/lateral/angular)
  1. Duct size & shape
👉 Our engineers will help you select the optimal design.

🛠 Installation & Maintenance

  • Do NOT twist or overstretch during installation
  • Avoid welding sparks or sharp edges near fabric
  • Regular inspection for aging or cracks
  • Replace the fabric layer if damaged
