What is Hot/Wet Tapping?

Hot/Wet Tap is defined as using a drilling machine to cut a hole into an in-service, under-pressure piping system. Hot/Wet tapping is a process of cutting holes into pipe, tanks, or any pressurized vessel without interrupting system function and with no release or loss of product. Hot taps permit new tie-ins to existing systems, the insertion of devices into the flow stream, permanent or temporary bypasses, and are the preparatory stage for line plugging. Hot/Wet/DryTap allows our customers to modify, maintain and repair pressurized systems with no interruption of production. Typical applications of a Hot Tap include making a branch connection, initiating a bypass and allowing performance of a Line Stop. Components required to perform a Hot Tap normally include a fitting designed to contain system pressure, a valve used to control the new connection and a drilling or tapping machine.

Hydrotastic Testing Capabilities

Wet Tapping and Hot Tapping are synonymous terms describing the cutting of a hole in an existing pressure main. A Tapping Sleeve and Valve are used to facilitate the cutting of the hole in the main while under pressure, providing a permanent branch connection. This can be performed on all types of pipe and under many flow and pressure conditions without interruption to the system. Cloud 9 provides our Wet/Hot Tapping Services from ¾  inch to 3 inch Tapped holes. Wet/Hot Tapping can be performed on all types of pipe materials and products.

Wet Tapping Process

The Wet Tapping process allows professionals to deliver supplementary tie-ins or modifications to an existing system that is either pressurized or in service without any interruption to that system. This essentially saves the customers large amounts of money that are involved in both the shutdown of the system as well as cutting into a mechanical tee.

The experts at Cloud 9 cut a hole into an existing main. The size of the hole depends on the services required. Our Wet Tapping Service uses different types of pipe tapping and drilling machines in order to install new connections for additional branches. This occurs within existing pipelines that are operating under various pressures up to 500 PSI and products. The Cloud 9 experts complete this process without leaking any product or any interruption to the system.


The Wet Tapping process generally uses a custom-designed fitting that contains system pressure, a valve that controls the new connection(s) and a drilling machine that cuts the pipe. Cloud 9 can perform taps on all pipe types including Cast Iron, Ductile Iron, Steel, Copper, Transite, Asbestos Cement, Concrete (PCCP) or PVC. Additional special applications are available upon request. Ultimately, by having your wet tapping process completed by our professional team of experts, you save not only time, but also money. Cloud 9 prevents shutdowns, repairs valves, installs sampling ports, fire lines or sensors, insolates pressure vessels and decommissions piping. These are just some of the many services that the Cloud 9 experts can perform for your system.

Hot/Wet Tapping Installation Process

During a typical wet tapping installation, the mounting of a tapping sleeve or saddle is performed to the systems’ main. The type used will depend on the person overseeing the system as well as the system’s requirements itself. After this mounting occurs, a permanent valve is installed and our expert team will then pressure test the system this newly installed material. This makes sure the integrity of the system is not compromised.

After the test is verified, our staff attaches our tapping machine to the valve itself. Based on the application chosen for the job, a hole or tap is made into the main, a tank or a pressurized vessel. The tapping machine used advances through both the tapping valve and sleeve. The bit cutter chosen is attached to this shaft and then makes the cut through the wall of the pipe itself. The bit pilot drill chosen helps to retains the cut pipe or coupon section when it is retracted. Ultimately, tap sizes can be from ½ inch to 48-inch holes. The piece that is removed, the coupon, is retracted from the main through the permanent valve we just installed with the same pressure required for the system. After this retraction, the valve is closed and the tapping machine disconnected.

Also known as corporation taps, wet taps usually occur within sewer or water mains. This typically occurs with commercial or residential services. The wet tap process allows for a new connection to be made without disruption to the service or flow of your product.

Difference Between Hot Tap vs. Wet Tap

Essentially these two Cloud 9 services are the same and both provide additional connections to a piping system. However the difference between the two is the material from which the systems are made from. Hot taps are performed on products which are something other than water and sewage and usually on pipes like copper, brass, stainless steel, carbon or galvanized steel, just to name a few. These types of materials require a more welded application then that of a wet tap that involves materials that cannot be welded. Typically hot taps are performed in more industrial settings such as hospitals, high rise buildings, chemical plants or refineries.
