Basically, wet taps and hot taps are usually synonymous and they describe a process where a hole is cut in an existing pressure main. A tapping valve and sleeve are normally used to help in cutting the hole while the under pressure offers a permanent branch connection. Generally, wet tapping can be done on pipes of all types and under various flow and pressure conditions without interrupting the system.

The installation process is beneficial to the relevant professionals and the system itself since they are able to change aspects of the system without disrupting it. This happens regardless of pressurization. This is an advantage to the customer as they save a lot of money which would have been spent on cutting mechanical tee and shutting down the system.

When cutting the hole on the existing main, the size usually depends on the type of service required. The process normally uses custom-designed fitting which contain a valve which controls the new connection, system pressure, and a drilling machine which cuts the pipe. The taps can be performed on all types of pipes including steel, ductile and cast iron, asbestos cement, copper, PVC and concrete. This process not only saves time but money as well. This is because there are no shutdowns.

During installation, mounting of the tapping sleeve is usually performed on the main. The type of the sleeve used depends on the system requirement and the person overseeing the system. After mounting has been done, a permanent valve is usually installed and pressure test on the newly installed material is performed. This is usually done to ensure the integrity of the system is maintained.

After testing has been verified, the tapping machine is then attached to a valve. Based on the application chosen for the task, a hole can then be made through a pressurized vessel, tank or a main. A tapping machine goes through a tapping valve or sleeve. The cutter bit is then attached to a shaft to cut through the wall of a pipe. After cutting, the cut piece is retracted from a main and the valve closed while the machine is disconnected.

Wet taps appear in areas like water mains, sewers, residential services and commercial land services. They ensure that that the flow of products of services is not disrupted. They are different from hot tabs in that they are carried out on various products apart from sewage or water. Hot taps are carried out in industries like chemical plants, refineries or hospitals.

The procedure might not be successful due to various factors. Such factors are such as an inexperienced personnel, incompatible equipment and materials, and piping materials which are difficult to tap or materials that are not recommended for that. To avoid such problems it is essential to use materials, equipment, and services from one manufacturer.

Upon hiring a company for the task, consider one with enough experience. The service provider should also be able to provide the service and ensure safety during repair and changing of the pipeline without shutdown of the whole system.
