DN65-DN3200mm Stainless Steel Dismantling Joint SS316L Customized
DN65-3200mm SS316L stainless steel double flange metal expansion joint
Expansion joints are primarily used in installation and maintenance, adjusted according to on-site requirements. They return axial thrust to the piping system during operation, improving efficiency while protecting pipeline equipment such as pumps and valves.
- Gland: Features thickened pressure plate with steel ring reinforcement for enhanced sealing and aesthetics
- Middle plate: Precision-turned with straight outer circumference for superior finish
- Nuts: Custom-sized bolts and nuts designed to standard flange specifications with anti-pull-off protection
- Welding: Post-weld finishing ensures no internal sand holes or cracks for reliable operation

For installation, connect the double flange limit expansion joint to both side flanges. Adjust the product length to match pipe/flange connections, tighten gland bolts evenly in diagonal sequence, then set limit nuts to allow controlled pipeline expansion/contraction while maintaining safety. Consider pipeline pressure, temperature, and media characteristics to ensure proper joint performance.
