The Compact Dismantling Joint (CDJ) allows valves and fittings to be installed, adjusted and removed without disturbing the adjacent pipeline, a maintenance saver over the life of the asset.
Overview
Steel Mains offers a new dismantling joint, the Compact Dismantling Joint. The design is highly advanced with upgraded features that assist with easier installation in confined areas, thanks to its compact length.
It is available in standard sizes of DN100, 150, 200, 225, 250, 300, 350, 375, 400, 450, 500, 600, 700, 750, 800, 900, 1000 and 1200, in both PN16 and PN35 pressure ratings to AS 4087, with larger sizes available on request. This unique, patented product is locally manufactured, reducing lead times for made-to-order sizes, and is proudly Australian designed and manufactured.
The length of the joint is shorter than previous designs, enabled by the integrated seal design and reduced thickness of the sealing flanges, so it can be safely installed where space is at a premium. The complete assembly is sandwiched in compression between the pipe flange and the pipeline component, making it one of the easiest dismantling joints to install and remove.
Features

- 100% restrained: external flange bolts sandwich the joint
- Significantly reduced length requirements
- Easy installation and removal when servicing pipeline components
- Angular misalignment tolerance
