Defence and naval systems demand a high level of reliability from the piping systems that support their critical equipment. Hydraulic and other high-pressure piping systems must perform consistently in demanding operating environments while meeting the stringent quality requirements associated with defence and naval applications.
Installation and maintenance can also be challenging within complex equipment layouts and confined vessel spaces. Reducing dependence on conventional welding can help simplify piping installation and maintenance while supporting efficient project execution.
Cenergy Offshore provides engineered non-welded piping solutions for defence and naval applications, including Pyplok® mechanically attached fittings and Tube-Mac® non-welded piping technologies for suitable high-pressure and other piping systems.
The challenge: reliable piping in demanding defence and naval environments
Defence and naval equipment requires dependable piping systems because the performance of connected hydraulic and other systems can directly affect equipment operation.
Naval vessels also contain complex arrangements of machinery, equipment and piping, often with limited space for installation and maintenance. Conventional welded piping can require additional fabrication, hot-work activities and inspection during installation or modification.
For defence and naval applications, the challenge is therefore not simply connecting pipes. The piping system must provide reliable connections while allowing installation and maintenance to be carried out efficiently within demanding environments.
The solution: engineered non-welded piping systems
Cenergy Offshore provides non-welded piping technologies for suitable defence and naval applications. These include Pyplok® mechanically attached fittings and Tube-Mac® non-welded flange systems.
By replacing suitable welded connections with engineered mechanical connections, these technologies can reduce dependence on on-site welding and simplify the installation of piping systems.
1. Faster installation with reduced hot work
Piping installation on defence equipment and naval vessels can involve complex layouts and restricted working areas. Conventional welding can increase installation time and require additional hot-work controls.
Non-welded piping systems reduce the amount of welding required for suitable applications, allowing piping connections to be assembled mechanically and helping simplify installation.
2. Reliability for demanding applications
Defence and naval piping systems are required to operate reliably in demanding service environments.
Pyplok® and Tube-Mac® technologies provide engineered mechanical connections for suitable high-pressure and other piping applications, supporting reliable piping performance where connection integrity is critical.
3. Simplified maintenance and replacement
Maintenance work on naval vessels and defence equipment can be complicated by restricted access and the close integration of piping with other systems.
Where the application permits, mechanically connected piping can simplify certain disassembly, replacement and modification activities compared with conventional welded connections, helping maintenance teams carry out piping work more efficiently.
Applications across Defence & Naval systems
Non-welded piping technologies can be used for suitable hydraulic, high-pressure and other piping applications across defence equipment and naval vessels.
