Dn350 Ansi Flange Type Stainless Steel Flexible Single Sphere Rubber Expansion Joint

Dn350 Ansi Flange Type Stainless Steel Flexible Single Sphere Rubber Expansion Joint

Product Description:

This single sphere expansion joint is designed to absorb vibration, reduce noise, and compensate for thermal movement in pipelines.

Featuring a DN350 (14-inch) nominal diameter, it incorporates a single sphere EPDM/NBR rubber body for excellent flexibility and corrosion resistance, especially in water, chemical, or industrial applications. The flanges are ANSI 150# standard, made from stainless steel (SS304/316), providing superior strength and long-term durability.

Key Features:

Size: DN350 (14”)

Connection: ANSI 150# Stainless Steel Flanges

Body: High-quality EPDM/NBR Rubber (customizable)

Flange Material: SS304 / SS316

Design: Single sphere for maximum flexibility

Working Pressure: PN10 / PN16 / ANSI Class 150

Temperature Range: -20°C to +120°C (depending on rubber material)

Applications: HVAC systems, water treatment, chemical processing, power plants, marine, and oil & gas industries

The range of size from DN15 to DN4000 are available.

Benefits:

1.Compensates for axial, lateral, and angular movements

2.Reduces noise and vibration in piping systems

3.Resistant to corrosion and aging

4.Easy installation with standard ANSI flange compatibility

Important Considerations:

Control Rods: For applications where excessive movement or pressure thrust could damage the expansion joint or adjacent equipment, control rods (tie rods) are often recommended or required. These rods limit the maximum extension of the joint.

Pressure and Temperature Ratings: Ensure the expansion joint's pressure and temperature ratings are suitable for the specific application. Different rubber materials have different operating limits.

Movement Capabilities: Understand the maximum allowable axial, lateral, and angular movements the joint can accommodate, and ensure these align with the system's needs. Note that typical single-sphere joints are designed for non-concurrent movements (i.e., not all movements simultaneously at their maximum).

Installation: Proper installation is crucial for the longevity and performance of the expansion joint. Floating flanges facilitate easier alignment during installation.
