Bellow Expansion Joint

Product Details:

Stainless steel bellows are flexible, corrugated components designed to absorb thermal expansion, vibration, and misalignment in piping and ducting systems. They are widely used in industries where durability, corrosion resistance, and high-temperature performance are critical.

1. Axial Bellows – Absorbs axial (lengthwise) movement.
2. Lateral Bellows – Handles lateral (side-to-side) movement.
3. Angular Bellows – Designed for angular movement.
4. Universal Bellows – Two bellows with an intermediate pipe for multi-directional movement.
5. Pressure Balanced Bellows – Used in high-pressure systems to minimize anchor loads.

• SS304 – General-purpose, good corrosion resistance.
• SS316 – High corrosion resistance, ideal for chemical and marine applications.
• SS321 – Better resistance to high temperatures.
• SS409/SS430 – Used in exhaust systems (automotive, industrial).

Product Details:

A non-metallic expansion joint is a flexible connector designed to absorb movement, vibration, and misalignment in ducting and piping systems. These joints are typically made from fabric, elastomers, or composite materials and are widely used in applications where metallic expansion joints may not be suitable due to factors like corrosion, weight, or complex movements.

1. Thermal Expansion Compensation

   • Absorbs expansion and contraction caused by temperature variations in duct and piping systems.
   • Commonly used in flue gas, exhaust, and hot air ducts in industrial plants.

2. Vibration & Noise Damping

   • Reduces mechanical vibrations from fans, blowers, turbines, and pumps, preventing stress on ductwork.

3. Misalignment Adjustment

   • Accommodates installation tolerances and shifting structures.
   • Useful in systems with large rectangular ducts and complex piping layouts.

4. Chemical & Corrosion Resistance

   • Made from PTFE, Viton, Neoprene, or EPDM, providing excellent resistance to aggressive chemicals, acids, and gases.
   • Ideal for chemical plants, power plants, and refineries.

5. Lightweight & Easy Installation

   • Easier to install and maintain than metallic expansion joints, reducing downtime and costs.
