Industrial Hot Tapping Services

What is a Hot Tap?

Hot tapping is a process for creating a new branch connection to an existing pipeline or tank while the system is still in service and pressurized. Typically, a weld-on or bolt-on saddle is attached to the pipe with a flanged outlet. A flanged valve is bolted onto the saddle, and a pressure-tight tapping machine attached to the valve. Next, the tapping machine bores into the pipeline. Once the tap is completed the valve is closed, the tapping machine is removed, and the new branch connection is now live.

The American Petroleum Institute RP2201 is a compilation of best practices and standards for Hot tapping in the petrochemical industry. Its authority dictates how to perform this service safely and correctly. An instructive flow chart in the standard is titled “Is the use of a Hot Tap Appropriate”.

After determining a Hot Tap is necessary, the next step is finding the best provider to fit your needs. There are important questions to consider when choosing a provider:

• Are their mechanics specially trained in hot tapping, formally tested, and experienced?
• Does the provider have documented procedures for maintaining and testing its equipment prior to arrival on the job site?
• Is their machinery specific for the intended service, or are they using waterworks equipment to perform in ways it was never designed?
• Has the Hot-tap mechanic provided a written procedure?
