Understanding Hot Tapping and Its Importance
What Is Hot Tapping?
Hot tapping, also known as live tapping, is a specialized process that allows for the installation of branch connections onto existing pipelines or vessels while they are still in service. This technique involves drilling or cutting into a pipeline without shutting down the flow, enabling repairs, extensions, or the installation of instrumentation without costly downtime.
Why Is a Hot Tapping Procedure PDF Crucial?
Having a detailed hot tapping procedure in PDF format offers several advantages:
- Standardization of operational steps
- Ensuring compliance with safety regulations
- Providing clear instructions for different scenarios
- Serving as a training resource for personnel
- Facilitating audits and inspection processes
