Connect your machine correctly to the right environment

Posted by Michael Donna on March 25th, 2020

Hot tapping, also referred to as a pressurized device (for example a pipe or a pressurized vessel) without removing the pipe or tank from the operating room is a technique for connecting the machine to a pressurized environment.

It is generally used for welding in-service equipment in the welding sense. Heat tapping is also used for the replacement or introduction of branches for system improvements, areas that have sustained mechanical damage and corrosion.

Using computer heat flow models and qualified using the flow loop, safe procedures for hot tap welding can be created. The cooling capacity of the live pipe for which measuring techniques are available is a part of this method.

The process is often used to drain pressurized containers and attach checkpoints or specific sensors like temperature and pressure. Hot tapping is also the first line stop technique, in which a hole-screw is used to open the thread so that a line connecting head is inserted.

Important Measures on Hot Tapping

• A hot tap is not a standard technique but is used only if there is no realistic alternative.

• Trained and qualified crews shall mount Hot Taps.

• It is important to remember that hot tapping of hot gas lines is of special concern to safety and metallurgy and is only performed in order to draw up authorized plans of the operating company.

• For any hot tap, an appropriate wall thickness shall be ensured in the pipe being drilled or sawed and can be measured with ultrasonic gauges of thickness.

• In Lethbridge Pipe Welding, pipelines require the production and certification of welding processes and a highly skilled workforce to ensure quality for the welds in full-pressure and full-flow operations of pipelines.

How to Set Hot Tapping

• For hot taping services in Lethbridge, the fitting device, the valve, and the hot tap mechanism are three main elements that can be firmly drilled into a pipe. The contact is primarily welded to the shaft.

• This fit is associated with a valve, which is associated with the valve with the hot tap mechanism.

• The fit/valve mix is applied to the tube and usually is checked with pressure.

• The stress check is very important to ensure that no structural issues are found and that no leaks occur in the welds.

• The hot tape cutter is attached to the holder of the cutter with the pilot bit and fits inside the tapping adapter on the workpiece end of the hot tape-machine.

• The tapping adapter provides a pipe device strain when the pipe is cut, the cutter and cutter holder is installed and the valve bolts are relocated.

Limitations on pipe welding in Lethbridge

• Must have proper vacuum conditions.

• Hydrogen dissolved in a tube wall

• Scale deposits of pyrophorus.
