In short
Shipyards consider grip type couplings for piping because they avoid hot work on board, are quick to fit and make it simpler to replace or maintain a section. Suitability depends on the model, materials, pressure, temperature and any class approval the project requires.
Why they suit shipbuilding and marine piping
- No hot work. Welding on board needs permits, precautions and time. A grip type coupling is fitted and tightened without welding.
- Speed. Fitting is quick, which helps programmes where many joints are made in confined spaces.
- Maintenance. A section can be loosened and refitted rather than cut and re-welded.
- Plain pipe ends. No threading, grooving or flange fitting is needed on the pipe.
What to check before specifying
- Materials and corrosion. Choose body, coating and seal materials suited to the medium and to a marine environment.
- Pressure and temperature. Check the rating of the specific model against the system design conditions.
- Class approval. Confirm any classification society or yard approval the project requires.
- Vibration and movement. Check the model's limits for alignment and movement, and support the pipework properly.
- Documentation. Make sure the certificates and datasheets your project needs are available.
