Metal Expansion Joint with Fixed Flange

Engineered for Stability, Strength & Long-Term Sealing in Rigid Installations

Metal Expansion Joints with Fixed Flanges are specially designed flexible connectors used in pipelines to absorb axial movement, thermal expansion, mechanical vibration, and system misalignment. Unlike floating flange types, these joints come with permanently welded steel flanges on both ends, offering a leak-proof and structurally rigid connection for high-pressure or critical applications.

Made from corrugated stainless steel (SS bellows) and reinforced to endure high temperature and pressure ranges, this joint is ideal for use in systems where alignment is controlled, and where movement is expected primarily in one direction.

Key Advantages

· Compensates for axial expansion and contraction due to thermal shifts

· Accommodates limited torsional and angular movements

· Isolates vibration from pumps, turbines, or engines

· Reduces noise transmission and protects system components

· Provides high structural strength and leak-free performance

· Built for long service life under demanding operating conditions

Applications

Metal expansion joints with fixed flanges are widely used in industrial and energy sectors for fluid, gas, or particulate flow under extreme temperatures and mechanical loads. Typical applications include:

· Exhaust systems of engines and turbines

· Power plants and boiler systems

· Chemical and petrochemical industries

· Shipbuilding and marine pipelines

· District heating and thermal fluid systems

· Heavy equipment and construction machinery

· Aerospace and nuclear industry pipe systems

Tested for Quality

Every unit is pressure- and vacuum-tested to ensure:

· Leak-tight performance

· Superior durability

· Trouble-free, long-term operation

Metal Expansion Joint with Floating Flange

Flexible Alignment – Easy Installation – Superior Vibration Control

Metal Expansion Joints with Floating Flange are specially designed for piping systems that require easier alignment during installation or frequent disassembly. This type features one fixed (welded) flange and one floating (rotating) flange, allowing the installer to rotate the flange during assembly to match bolt holes without twisting the bellows.

Constructed using high-quality stainless steel bellows and engineered for pressure, temperature, and movement compensation, these joints are ideal for systems that demand flexibility during installation or maintenance, while still ensuring long-term sealing and performance.

Key Advantages

· Ease of Installation – Floating flange rotates to match flange holes, avoiding alignment issues

· Absorbs axial, angular, and limited lateral movements

· Reduces stress on piping systems due to thermal expansion

· Dampens vibrations and mechanical shocks

· Ideal for areas where piping movement or flange rotation is necessary

· Reliable sealing performance without compromising flexibility

Applications

Metal expansion joints with floating flanges are suitable for a wide range of industrial uses where installation convenience and operational reliability are both critical:

· Pump and compressor connections

· Steam and exhaust systems

· Power generation plants

· HVAC and chilled water lines

· Chemical and process industries

· Marine and offshore piping systems

· Turbine and engine exhaust ducts

Built to Perform

Each unit is individually tested for pressure and vacuum resistance to ensure:

· Safe operation

· No leakage

· Consistent performance under dynamic load conditions

Metal Expansion Joint – Groove End Type

Compact, Quick-Connect Design for Fast Installation in Tight Spaces

Groove End Metal Expansion Joints are designed for easy and secure installation using mechanical couplings such as Victaulic or clamp-type connectors. Instead of flanges, both ends of the stainless steel bellows feature rolled or machined grooves that allow fast connection without welding or bolting — making them ideal for compact or modular piping layouts.

These joints effectively absorb axial and angular movement, reduce vibration, and accommodate thermal expansion. Their space-saving design, combined with rapid assembly and disassembly capability, makes them a top choice in modern piping systems where speed, flexibility, and reliability are essential.

Key Advantages

· Grooved ends for quick, weld-free installation using mechanical couplings

· Absorbs axial and angular movements caused by thermal expansion

· Allows for fast maintenance or replacement in modular systems

· Reduces vibration, stress, and noise in the piping system

· Compact construction ideal for confined installations

· Suitable for horizontal and vertical piping configurations

Applications

Groove end metal expansion joints are widely used across industries where space, speed, and efficiency are key factors in piping system design:

· HVAC and fire protection systems

· Commercial and residential buildings

· Modular plant installations

· Power plants and utility services

· Chemical and water treatment systems

· Compressed air and process fluid lines

Performance & Testing

All units are subjected to rigorous pressure and leak testing to meet international quality standards and ensure:

· Secure coupling under operating pressure

· Durability in dynamic load conditions

· Maintenance-free, long-term service life

Braided Metal Expansion Joint

Enhanced Pressure Control and Vibration Resistance for Dynamic Piping Systems

Braided Metal Expansion Joints are flexible stainless steel bellows reinforced with an external wire braid that increases the joint’s ability to withstand internal pressure, control axial movement, and suppress vibration. These joints are engineered to handle pulsating flows, mechanical motion, and pressure spikes in highly dynamic systems.

Depending on application requirements, we offer two configurations:

· Single Braided: One outer braid layer for moderate pressure and vibration environments

· Double Braided: Two interwoven braid layers for high-pressure systems or where added strength is essential

The braided sheath not only enhances mechanical strength but also limits overextension of the bellows under pressure, making it an ideal solution for demanding industrial applications.

Key Advantages

· Controls internal pressure and reinforces bellows strength

· Absorbs axial vibration, movement, and system pulsation

· Minimizes mechanical stress and noise transmission

· Available in both single and double braid configurations

· Suitable for high-temperature and high-pressure applications

· Flexible and compact design allows easy installation in tight spaces

Applications

Braided metal expansion joints are essential in systems that operate under continuous motion, thermal fluctuation, or high-frequency vibration, including:

· Diesel generator exhaust systems (DG sets)

· Pump discharge and suction lines

· Steam and condensate pipelines

· Turbine and engine exhaust manifolds

· Compressed air and gas systems

· Process industries with high pressure/temperature fluid transport

Precision-Engineered for Performance

Each braided joint undergoes leak testing, pressure testing, and dimensional validation to ensure:

· Long-term safety under dynamic conditions

· Resistance to fatigue, rupture, and wear

· Maintenance-free, high-efficiency operation
