Installing pipework, valves and other mechanical equipment to existing services can be a complex process that requires careful planning and execution. It involves connecting new pipes to existing plumbing or heating systems to expand or modify the existing network. We will assess the existing system, selecting appropriate materials and fittings, and discuss with you a new layout that incorporates the new pipework. The installation process can also involve cutting and welding pipes, threading fittings, and using various connection methods, such as compression fittings or soldering.
Professional installation services are crucial for ensuring that the new pipework is installed safely and correctly, minimizing the risk of leaks, system failures, or damage to the existing services. It is also important to ensure that the new pipework meets relevant codes and regulations, and that the installation process is completed efficiently and with minimal disruption to existing services. Overall, installing pipework to existing services requires a high level of expertise and experience, and it is important to work with a qualified professional to ensure a successful installation.
Hot Tapping / Under Pressure Drilling
Hot tapping is a plumbing and HVAC technique that allows for the creation of a new branch connection on an existing heating or chilled water pipe without interrupting the system. It involves drilling a hole, fitting a specialized valve assembly, and making the branch connection, all while the system remains in operation. This method is cost-effective and efficient, especially when the pipeline is in continuous use.
Pipe Freezing
Pipe freezing is carried out by clamping a specially designed insulated ‘jacket’ around the pipework at the point to be isolated, providing an annular space between the pipe wall and the outer skin of the jacket.
Cryogenic refrigerant (typically liquid nitrogen) is then introduced into the annular space, creating a bath around the pipe at cryogenic temperatures.
As heat is exchanged between the pipe contents and the liquid nitrogen bath, the temperature of the contents is reduced and an iceplug gradually forms, from the outer wall inwards towards the centre of the pipe.
