Single arch with floating flange rubber expansion joint

Designed for Performance, Built for Flexibility

Smart Design for Demanding Systems

The rubber expansion joints offered by Flexotech are designed with a single wide-arch construction that ensures uniform pressure distribution and prevents sediment buildup. This self-cleaning, spherical arch design helps reduce the load on pipelines and connected equipment.

These joints are reinforced with high-strength nylon cord fabric and equipped with steel floating flanges, offering superior flexibility and resistance. Their sealing surfaces provide a leak-proof, gas-tight connection, ensuring reliable operation under challenging conditions.

Why It's the Ideal Pump Connector

Rubber bellows are widely used as pump connectors across industries. Their resilient design helps:

• Absorb vibrations and pulsation shocks

• Reduce noise transmission

• Withstand high pressures, temperatures, and frequent movements

This makes them a trusted choice for suction and discharge lines.

Key Advantages

• Wide Flowing Arch – Minimizes blockage and sediment collection

• Floating Flange Design – Simplifies installation and alignment

• Multidirectional Movement Compensation – Absorbs axial, lateral, angular, and torsional movements due to thermal expansion or misalignment

• Vibration & Noise Isolation – Helps dampen operational noise and pressure surges

Where It’s Used

Flexotech supplies rubber expansion joints suitable for applications in:

• 🏠 Residential Buildings

• 🏢 Commercial Complexes

• 🏭 Industrial Facilities

• 💧 Sewage and Water Treatment Plants

• ⚗️ Chemical and Petrochemical Plants

• ⚡ Power Generation Stations

• 🚢 Marine and Shipboard Systems

Double arch with floating flange rubber expansion joint

Superior Flexibility & Shock Absorption for Dynamic Piping Systems

Advanced Design for Enhanced Movement Control

Double Sphere Rubber Expansion Joints offer all the benefits of single sphere joints — but with greater flexibility and movement capacity. Their unique dual-arch design and extended body allow for superior compression, elongation, lateral shift, and angular motion. This structure also provides improved shock absorption, noise suppression, and protection from water hammer and hydraulic surges.

Crafted from durable rubber bellows reinforced with nylon cord fabric and finished with steel floating flanges, these joints deliver reliable sealing, flexibility, and long-term resilience in high-vibration or high-pressure systems.

Rubber Joints with Floating Flanges – Ideal Pump Connector

Double sphere joints are a preferred solution for protecting pumps and mechanical equipment in pipelines. Their resilient design:

• Absorbs mechanical stress and thermal expansion

• Minimizes transmission of vibration and pulsation

• Withstands demanding operating conditions across industrial sectors

Key Features & Advantages

• Double Arch Structure – Increases movement capacity and pressure absorption

• Wide Flowing Design – Prevents sediment buildup for clean and efficient flow

• Floating Flange – Allows quick alignment and easy installation

• Multi-Directional Flexibility – Compensates for axial, lateral, angular, and torsional shifts due to misalignment or temperature change

• Shock & Vibration Isolation – Dampens noise, pulsation, and hydraulic surges

• Perfect for Suction & Discharge Lines – Reliable in both static and dynamic conditions

Tubular type with Fixed Flange rubber expansion joint

Spool-Type Rubber Bellows Engineered for Strength & Reliability

Design & Construction

The spool-type rubber expansion joints supplied by Flexotech are precision-built using a combination of high-strength nylon cord fabric, premium elastomer, and reinforced metal rings and wires. These robust joints feature integral full-faced flanges, permanently bonded with the body for improved stability and performance.

Instead of conventional gaskets, these joints use split steel retaining rings drilled to international standards. The gas- and fluid-tight sealing surface of the rubber bellows ensures a secure, leak-proof connection—eliminating the need for additional sealing components.
