HOT / WET TAP OVERVIEW
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.

Angle Hot Tapping
This procedure refers to any hot tap where the centerline of the tapping nozzle is not perpendicular to the surface being tapped. We are currently equipped to perform angle taps in sizes 1″ through 24″, as much as 45° off perpendicular, and into the heel of short or long radius ells.
Tapping Blind Flanges and Heavy-wall Vessels
Hot tapping heavy-wall vessels and blind flanges is not a problem, provided special issues are addressed in the design of the branch connection.
Tapping Materials other than Carbon Steel
In addition to carbon steel, we commonly tap cement lined pipe, asbestos cement, transite, cast iron, stainless steel and other alloys, plastic and fiberglass. Although we tap these materials frequently, additional information such as the thickness and composition of linings, hardness of alloys, or type of fitting and valve through which we will be operating may be needed to insure that proper equipment is provided for your job.
Tapping Materials that Cannot be Welded
If it is necessary to tap or plug a line that cannot be welded, such as cast iron, ductile iron, transite, or even carbon steel in an area where welding is not permitted, a bolt-on tapping or plugging fitting can be provided. EA Tapping Services offers mechanical fittings by Smith-Blair, giving us the latitude to provide the right fitting at the right price and delivery for your job. If a standard product does not suit your application, one can be custom fabricated that will meet your needs.
