Hot Tapping

Follow us

Our unique range of specialist hot tapping equipment enables a connection to be made to a piping system or a vessel without shutdown or interruption to production.

Hot taps can be performed safely on most types of pipes, ranging from carbon steel to GRE. They can be carried out on systems containing oil, gas, fuel, steam, water and many other line mediums with pressures up to 1000 psig @ 100 Deg. F.

Line material

  • Asbestos-Cement
  • Stainless steel
  • Steel cylinder
  • Carbon steel
  • Ductile iron
  • Equipment


Line contents

  • Crude oil
  • Gasoline
  • Water
  • Steam
  • Natural gas
  • Wastewater


Our pipeline services use the latest available technology in coupon retention. When a hot tap is performed, the double wired pilot drill retains the coupon for recovery when the process is complete.

A typical hot tap installation consists of a tapping saddle, ball or gate valve, and Hot Tapping Machine. The installation is pressure tested, the valve is opened and the cutter and pilot drill advanced. When the cut is complete, the cutter and pilot drill is retracted, the valve is closed and the Hot Tap Machine is removed. 

Unique Group's Hot Tap capabilities:

  • Lines from 0.5" to 48" in diameter
  • Temperatures from cryogenic to 1,350°F (400°C)
  • Pressures from atmospheric to 1,000 psig (69 bar)


Beyond the addition of new branch connections to your piping, our hot tap services can also be applied for other purposes.

  • Product sampling point
  • Flow Meter installation
  • Thermo-well Sensor installation
  • Draining of pipelines
  • Pressure Control Switch installation
  • Pipeline inspection
  • Determine product in a pipeline
  • Air Relief Point


We have the ability to tie into your system in many different ways. Angle taps, valveless connections, long travel taps, and other methods are also available to complete your connection in the most efficient manner possible. Our equipment is designed and tested to withstand the required operating pressures, extreme temperatures, and harsh working environments.

A comprehensive Hot Tapping package is available, including a detailed survey of your site to determine the most efficient solution: one that's delivered by our highly skilled and experienced engineers.
