HOT
Tapping
Companies are often required to make modifications to their existing process piping systems, vessels or tankage systems for reasons of expansion or maintenance.
Hot Tapping or under pressure drilling, is a method of making a connection to existing pipelines or tanks while the system is under pressure.
This method employs a drilling or tapping machine, a full ported valve and a pressure containing fitting to the existing pressurized system.
The end result, a new branch connection abstracted from the original pipe while the line is in operation.
