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.
