Hot tapping to insulate pipeline
When you have to fix a pipeline without draining that system, hot tapping method is implemented. This technique is used to attach a branch of connection to the existing pipeline while it is working to create alternative opening by cutting and drilling to insulate hot tapping and repair the pipe. Mostly, hot tap is done in pipe and sometimes they are done on vessels and storage tank. Hot tapping adds connection without interruption and depressurization of working system. This technique is also used to isolate pipe sections for maintenance. This process is completed successfully everyday without disruption, though this process is a dangerous operation.
This option has to be chosen when it is not possible to take system out of service. When you choose hot tapping inspection, design and testing should be carried out careful to result in safe and reliable manner. Hot tapping needs more care and so this options should be chosen only after every other option evaluation is rejected. In most cases, hot tapping services singapore are made without any difficulty. Hot tap needs extra precautions than any other procedures. Every aspect can be evaluated based in the service, pipe material and the location to hot tap. Hot tapping can be done when the following conditions are present:
- Piping is inflammable
- Piping does not have acids or any other chemicals that are hazardous or decompose with the heat produced during welding.
- Tap with the pipe that contains hydrocarbon.
- Can be used on Stainless steel piping without catacarb solutions.
Hot piping is best in the unavoidable system work without interrupting any work.
