B2F DN500 Dismantling Joint Double Flange Limited Dismantling Coupling

Double flange limit expansion joint is an important element used for pipeline connection, composed of body, sealing ring, gland, limit screw, limit expansion tube, nut and bolt components. Its main function is to expand and contract freely within the allowable range, with the limiting device ensuring pipeline safety when maximum expansion is exceeded. Ideal for pipelines with vibration or certain slopes and bends.

• Body: Withstands pipeline pressure and thrust.
• Sealing ring: Prevents leakage, made of NBR nitrile rubber with large sealing area.
• Gland: Fixes the sealing ring to prevent leakage.
• Limiting screw: Limits maximum pipeline expansion to prevent damage.
• Limit expansion and contraction pipe: Allows controlled pipeline movement.
• Nuts and bolts: For pipe position adjustment and fixation.

• Compact structure: Designed to withstand large pressure and temperature fluctuations.
• Large expansion capacity: Absorbs significant pipeline displacement.
• Excellent sealing: High-temperature resistant materials prevent leakage.
• High pressure tolerance: Ensures stable operation in demanding environments.
• Limit protection: Prevents damage from excessive expansion.

• Easy adjustment: Accommodates thermal expansion and contraction.
• Simple installation: Flange connection for quick assembly.
• Enhanced safety: Limit protection prevents system failure.
• Wide compatibility: Suitable for various media including water, oil, and gas.
• Vibration absorption: Reduces noise and system stress.
• Cost-effective: Lowers maintenance and operational costs.

• Thermal piping systems: Accommodates thermal expansion in heating systems.
• Industrial pipelines: For petroleum, chemical, and metallurgical applications.
• Water supply systems: Protects against vibration in municipal water networks.
