DN800 Double Flange Dismantling Joint - Stainless Steel High Pressure Compensating Pipe Connector 12-Month Warranty
A dismantling joint is a specialized device for connecting pumps, valves, and other equipment to pipelines. It features full-bolt connections that create a unified assembly while allowing for controlled displacement during installation and maintenance. Constructed from durable materials including carbon steel, stainless steel, or ductile iron, its components include long flange body, short flange body, sealing ring, stud, washer, and nut.
This dismantling joint consists of a flange loose sleeve expansion joint, short pipe flange, and force transmission screws. It effectively transmits pressure thrust from connected components while compensating for pipeline installation errors. The design accommodates flange connections on both sides, with adjustable installation length and uniform diagonal tightening of gland bolts for secure assembly.
- Quick Operation: Fast opening and closing mechanism suitable for frequent use
- Low Fluid Resistance: Optimized structure minimizes flow resistance
