Discover double sphere rubber expansion joint for flexible pipeline connection. Strong resistance to pressure, corrosion, and misalignment. Save maintenance costs with long service life.

Product Description

The double sphere rubber expansion joint is a flexible connector specially engineered to absorb axial, lateral, and angular movements in piping systems. Compared with single sphere models, its double-arch structure provides greater displacement capacity, ensuring stable performance under high pressure and misalignment conditions.

✅ Why Choose double Flexible Pipe Connector?

1.Longer service life with reinforced nylon cord & galvanized flanges.

2.Absorbs pipe misalignment and thermal expansion effectively.

3.Strong resistance to corrosion, suitable for water, oil, acid, and alkali.

4.Reduces downtime and maintenance costs.

✅ Where It Works Best:

Chemical processing plants

Wastewater treatment pipelines

Oil & gas transportation lines

Industrial pump and compressor systems

Our double sphere rubber expansion joint is the trusted choice for global contractors and distributors who value reliability, safety, and cost-effectiveness.

Different Types of Double-Ball Rubber Joints

Installation Guide

1. Clean the flange surface before installing the joint.

2. Install the rubber joint between two flanges and insert bolts evenly.

3. Tighten bolts crosswise to ensure uniform sealing pressure.

4. Avoid excessive stretching or compression beyond the product’s rated displacement.

5. For vertical pipelines, install a support or hanger to bear the weight of the pipeline.
