Closing the Gap in Pipeline Engineering
In a perfect world, pipes would align perfectly with every valve and pump. In reality, on-site measurements often vary, and rigid systems leave no room for error. This is where the Dismantling Joint becomes indispensable. It acts as a telescopic bridge, closing the gap between flanges and providing the necessary clearance to slide equipment in and out of the line.
1. Telescopic Adjustment: The 50mm Advantage
The core design of a B-NAI dismantling joint allows for significant longitudinal adjustment (typically up to 50mm or more depending on size).
Stress-Free Installation: By adjusting the tie rods, the joint can be compressed to provide space for a valve gasket or extended to meet the mating flange. This prevents damaging the pipe or valve flanges during bolting.
2. Full-Length Tie Rods for Load Transfer
Unlike simple expansion joints, our dismantling joints are equipped with full-length tie rods (studs) that span the entire assembly.
Stability: These rods play a dual role: they facilitate the telescopic adjustment during installation and act as a rigid bridge once tightened, transferring the pressure thrust through the joint and ensuring the assembly remains stable under high-pressure surges.
3. Robust Sealing and Corrosion Protection
B-NAI dismantling joints are built for decades of service:
Superior Sealing: We use high-grade EPDM or NBR trapezoidal gaskets that provide a reliable seal even after repeated adjustments.
Industrial Coating: Each unit is sandblasted and coated with heavy-duty fusion-bonded epoxy (min. 250 microns), resisting corrosion in buried or submerged environments.
