The Single Sphere Rubber Expansion Joint is a flexible connector widely used in industrial and civil pipeline systems. Its spherical structure allows high flexibility, making it an excellent solution for absorbing pipeline vibration, reducing noise, and compensating for axial and lateral displacement.

Made from premium rubber materials such as EPDM, NBR, and Neoprene, this expansion joint ensures outstanding resistance to water, oil, and a variety of chemicals. The flanged ends are designed according to international standards (DIN, ANSI, JIS), making installation compatible with global piping systems.

Compared to double sphere models, the single sphere design offers compact size and cost-effectiveness, ideal for space-limited installations without sacrificing performance.

By choosing our single sphere rubber expansion joint, you ensure long service life, safe operation, and improved efficiency in your pipeline system.

Installation Brief Instructions

1. Align the flanges of the rubber expansion joint with the pipeline flanges.

2. Insert bolts and tighten them crosswise to ensure uniform pressure.

3. Avoid over-tightening to prevent damage to the rubber body.

4. Do not install near sharp objects or under direct sunlight for long periods.

5. For vertical pipelines, use support to avoid the weight stressing the joint.

FAQ

Q1: What is the difference between single sphere and double sphere rubber expansion joints?
A1: The single sphere design is more compact and cost-effective, while the double sphere offers higher displacement absorption.

Q2: Can this expansion joint be used for drinking water?
A2: Yes, when using food-grade rubber material.

Q3: What flange standards are available?
A3: We provide DIN, ANSI, JIS, BS, and customized drilling standards.

Q4: How long is the service life?
A4: Typically 3–5 years under normal conditions; service life depends on working medium, temperature, and pressure.
