The BasicsHot Tapping is the ability to safely tie into a pressurized system while it is on stream and under pressure.

Typical connections consist of a tapping fitting, isolation valve, and hot tapping machine. The hole saw is

advanced through the valve, to the pipe. The machine is engaged and the cut begins. When the cut is

finished, the machine is disengaged and retracted beyond the gate of the valve. The valve is closed and the

machine is removed.

Coupon retention is made possible by a

few different methods. The most reliable

and most common is the double-wired

pilot drill. A catch wire is placed at the end

of the pilot drill. When wall penetration is

complete, the wire drops into position and

retains the coupon.

Why Hot Tap?• New Connection

• Product Sampling Point /

Product Determination

• Installing Instrumentation Equipment

• Draining of a Piping System

• Internal Pipeline Inspection

Hot taps can be performed on most any type of pipe, ranging from carbon steel to PVC. Taps are done on

lines containing water, oil, gases, fuels, steam, and many other chemicals.

Angled Hot Tap

Valveless Connections

Koppl can perform hot taps in almost any situation. From tight locations in buildings to open trenches in the field, we have the right equipment for your application.

These fittings are used when valves are not required at the point

of connection. A temporary valve is used to make the hot tap,

then removed. All this accomplished is with no interruption of

service. Can also be used for purging and bypassing.

Koppl has the ability to tie into your system in many different ways. Angle taps, valveless connections, long travel taps, and other methods are available to complete your connection in the most efficient manner possible.
