What is hot tapping and line stopping?

Zero Down Time Modification & Remedial Work with Pressure Vessels

Hot tapping and line stopping are both techniques used in the maintenance and repair of pipelines. Hot tapping is a method of creating a connection to a pipeline while it is still in service. This is done by drilling a hole into the pipe and installing a tapping valve, which allows for the connection of a new line or the insertion of a tool for maintenance or repair.Line stopping, on the other hand, is the process of stopping the flow of fluid in a pipeline so that maintenance or repairs can be done. This is done by inserting a line stop fitting into the pipe, which blocks the flow of fluid and allows for the section of pipe to be taken offline for maintenance or repair. Both hot tapping and line stopping are important tools for ensuring the safe and efficient operation of pipelines, and are used in a wide range of industries, including oil and gas, water and sewage, and chemical manufacturing.
