Hot Tapping

Wellube provides a complete bespoke package for your hot tap requirements - from designing, manufacturing and installation of the fittings on the system to performing the intervention.

Preserve pipeline integrity & avoid downtime with Wellube’s Hot Tapping Services - the industry’s most trusted service provider.

Hot tapping, commonly referred to as pressure tapping, is a way to attach to a pressurised system, like a pipeline or pressure vessel, without taking the pipe or tank out of operation (either through drilling or cutting). This keeps operations going while preventing expensive and potentially dangerous environmental concerns.

Installing connections to pipes while they are still in use is known as “hot tapping.” It is frequently used in the context of welding for any welding onto equipment that is already in use. The hot tapping process is often used to add branches to an existing system or to repair mechanically damaged or corrosion-damaged areas. Executing this welding without taking a pipe out of operation and potentially releasing significant amounts of greenhouse gases, such as methane, has clear economic and environmental benefits.

Using computer heat flow modelling methodologies and flow loops, safe hot tap welding procedures can be developed. This strategy includes matching and controlling the cooling capacity of the live pipeline, which may be measured.

Our hot tapping services are effective and uphold the highest performance standards.

Oil and gas, power, and utility pipeline maintenance industries hire Wellube to establish requirements, evaluate proposals, manage projects, and provide technical consultancy. We can offer specialized applications as part of our hot tapping service.

A connection to a piping system or a vessel can be formed using our specialized hot tapping equipment without shutting down or interrupting operations.

On the majority of pipe types, from carbon steel to GRE, hot tapping services can be carried out without risk. They can be performed on systems with pressures up to 1000 PSIG @ 100°F and contain fuel, steam, water, oil, gas, and many other line mediums.

A tapping saddle, ball or gate valve, and hot tapping machine make up a standard hot tap installation. The cutter and pilot drill are progressed, the valve is opened, and the installation is pressure checked. The Hot Tap Machine is withdrawn after the cut is finished, the cutter and pilot drill is retracted, and the valve is shut.

Our pipeline and hot-tapping services utilise the most cutting-edge coupon retention technology. When a Hot Tap is carried out, the double-wired pilot drill holds onto the coupon for later recovery.

Our machinery is built to endure high operating pressures, chilly temperatures, and challenging working conditions.

Remarks before making a Hot Tap

  • Hot taps should only be used when there is no other viable option; they should not be utilised often.
  • Hot Taps must be placed by skilled and knowledgeable teams.
  • It should be highlighted that hot tapping of sour gas lines offers unique metallurgical and health risks and should only be carried out according to written operating company-approved guidelines.
  • The pipe that is sawed or drilled for each hot tap must have a sufficient wall thickness, which can be assessed using ultrasonic thickness gauges. The actual thickness of the pipe wall must at least match the thickness needed for pressure, plus a sufficient thickness allowance for welding. The risk of loss of containment at the weld pool exists if the actual thickness is only marginally greater than the thickness necessary for pressure.
  • To ensure the integrity of welds when pipelines are operating at full pressure and under full flow circumstances, welding on in-service pipelines involves developing weld process and qualification, as well as highly trained personnel.

When to use Hot Tapping?

Hot tapping is a technique to join a branch connection to a pipeline without depressurizing it or interfering with regular operations. The method is also utilised to isolate pipe segments for maintenance by stopping or plugging the line. Line tapping, pressure tapping, pressure cutting, and side cutting are also used to describe hot tapping.

The advantage of hot tapping is that it enables pipeline owners and operators to isolate and bypass pipeline portions for maintenance or when adding a new section of the pipeline without having to shut down their entire system, halt production, and incur expensive downtime. Use of a hot tap while.

Hot tapping in piping is a significant procedure that can be dangerous if carried out incorrectly. Because of this, we advise only utilising a hot tap if there is no other way to complete repairs or build a new pipeline branch; it is impracticable to shut down the entire system or both. You can use hot tapping after evaluating and eliminating all other possibilities.

Benefits of Hot Tapping

Using a hot tap instead of a system shutdown has several financial and environmental advantages. Hot tapping doesn’t waste gas, interfere with customer service, or release dangerous gases into the atmosphere. Additionally, you can decrease costs associated with organising and planning a full system or section shutdown, as well as the time-consuming cutting, realigning, and re welding of pipeline sections.
