Dismantling Joint
A Dismantling Joint is a critical pipeline component designed to simplify the installation, removal, and maintenance of valves, pumps, and other flanged equipment. It provides axial adjustment and flexibility, allowing precise alignment between pipe sections while maintaining a secure, leak-tight connection. Commonly used in water, wastewater, oil, and industrial piping systems, dismantling joints reduce downtime, ease maintenance operations, and help absorb minor movement or misalignment within the pipeline.
Applications
- Suitable for pipeline systems with flanges on both sides
- Used where installation length adjustment is required during fitting
- Ideal for pipelines requiring easy alignment of flanged equipment
- Allows diagonal tightening of pressure cap bolts for uniform load distribution
- Facilitates quick installation, dismantling, and repair of valves and equipment
- Can be adjusted according to site conditions and available space
Features:
- Adjustable installation length
- Flanged ends on both sides
- Easy installation and dismantling
- Allows axial movement
- Uniform bolt tightening
