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

Stainless steel
Steel cylinder
Carbon steel
Ductile iron

Line contents

Crude oil
Natural gas
Waste water

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 are retracted, the valve is closed and the Hot Tap Machine is removed. 

Wellube Hot Tap capabilities:

Lines from 0.5" to 48" in diameter
Temperatures from cryogenic to 1,350°F (400°C)
