Construction and Materials
This expansion joint is constructed with a high-quality rubber body, typically made from EPDM, NBR, Neoprene, or natural rubber, selected based on the specific media and operating conditions. The rubber body is reinforced with multiple layers of high-strength synthetic cord fabric, providing excellent pressure resistance and dimensional stability. The flanged ends are equipped with integrated steel wire or hard rubber beads, ensuring a secure and leak-proof connection to mating flanges. The double-sphere configuration offers greater flexibility and movement absorption capacity compared to single-sphere designs.
Key Features
The double-sphere design allows for superior axial movement, lateral deflection, and angular displacement, effectively reducing stress on pipelines and connected equipment. The axial floating capability enables the joint to compensate for thermal expansion and contraction along the pipe axis. The flanged connection ensures easy installation and maintenance, compatible with standard ANSI, DIN, JIS, or BS flanges. The rubber construction provides excellent resistance to abrasion, corrosion, and aging, while effectively dampening vibration and noise transmission. The product is lightweight, compact, and requires no additional gaskets or special tools for installation.
Technical Specifications
The DN150 6"expansion joint is designed to operate within a working pressure range of typically 10 to 16 bar, depending on the rubber material and reinforcement configuration. The burst pressure generally exceeds four times the working pressure. The allowable axial movement is typically ±20 mm to ±30 mm, while lateral deflection can reach ±20 mm, and angular displacement up to 15 degrees. The operating temperature range varies by material: EPDM from -40°C to 120°C, NBR from -20°C to 80°C, and Neoprene from -30°C to 100°C. The flange dimensions conform to standard specifications, with a face-to-face length designed to match common piping requirements.
Applications
This rubber expansion joint is widely used in water supply and drainage systems, HVAC systems, chemical processing plants, power generation facilities, marine and offshore applications, and industrial pipeline networks. It is particularly suitable for systems where thermal expansion, vibration isolation, and misalignment compensation are critical. The DN150 size makes it ideal for medium-diameter pipelines in both commercial and industrial settings.
Installation Guidelines
Proper installation is essential to ensure optimal performance and service life. The expansion joint should be installed with the flanges aligned parallel to the mating flanges, avoiding excessive offset or misalignment during bolting. Bolts should be tightened evenly in a diagonal pattern to prevent uneven stress on the rubber body. The joint should not be used to support pipe weight, and proper pipe guides and anchors should be installed as required by system design. Care should be taken to protect the rubber body from sharp edges, welding sparks, and excessive heat during installation.
Quality Assurance
Each DN150 6"Double Spheres Axial Floating Flanged Rubber Expansion Joint Connector undergoes rigorous quality control, including dimensional inspection, pressure testing, and material verification. The product complies with relevant international standards such as ISO 9001, CE, and API 610 where applicable. Custom materials, flange standards, and pressure ratings are available upon request to meet specific project requirements.
