DN600 PN16 Carbon Steel D-Type Large Deflection Expansion Joint with ±60mm Expansion Capacity and 720mm Length
D-type large deflection loose sleeve compensation joint is a high-performance pipe connector featuring double flange construction with bolt and nut fastening for reliable pipeline connections. Engineered to withstand pressure variations and temperature fluctuations while effectively absorbing pipeline displacement and vibration, preventing safety incidents from pipe fractures or leaks.
- Stub flange: Connects both pipe ends
- Gland: Provides fixation and sealing
- Sliding pipe: Enables free expansion and contraction
- Sealing device: Ensures connection integrity
The anti-axial force design delivers simple structure, reliable sealing performance, strong tensile resistance, and substantial deflection capacity for demanding applications and complex terrain conditions.

- Reliable Performance: Anti-axial force design ensures simple structure with dependable sealing and strong tensile resistance
- Superior Pressure Handling: Maintains tight pipeline grip under pressure with excellent compressive performance
- Enhanced Adaptability: Absorbs axial, lateral, and angular thermal deformation while reducing equipment vibration impact
- Durability: High-performance materials provide corrosion resistance, wear resistance, and temperature tolerance from -40°C to 150°C (350°C in special cases)
- Long Service Life: Advanced materials and structural design deliver extended operational lifespan comparable to pipeline fatigue life
- Easy Installation & Maintenance: Simple installation without complex tools, with straightforward maintenance procedures
- Versatile Applications: Suitable for chemical, construction, water supply, drainage, and circulating water systems
The D-type large deflection loose sleeve compensation joint connects to flanges on both sides, secured with bolts to form an integrated system. During installation, tighten gland bolts and nuts diagonally and evenly to ensure free pipeline expansion and contraction, locking expansion mechanisms to protect pipeline safe operation.
