Sometimes also knows as pressure tapping, hot tapping is a commonly used procedure involves the connection of existing pipeline or vessels without the need to empty the connected section of pipe or the vessel. The best thing about hot tapping pipelines is that it allows engineers to continue their work eliminating the need to shut down the entire process or system. It can easily be done on pipes carrying water, sewage, natural gas, steam, chemicals, and petroleum products, and it can be done on pipes made out of any type of material. The process can be done on offshore platforms, gas production plants, refineries, and at any other location where a pressurized tubular system exists. Let’s discuss this technique in detail.
There are several steps in the technique of hot tapping pipelines. The first step uses a hole-saw to make a hole in the pipe into which a plugging head is inserted. This head allows pressure to be restricted, vented, and removed from a live pipe line.
When it comes to benefits, there are lots of them. Hot tapping pipelines allow for simultaneous operations since pressure is totally contained. Repair work can be done on any section of the pipe without shutting down other sections. The system is very modular, also, and can handle different applications. is limited only by the amount of pressure that has to be contained; this means that, if a way to contain the pressure is available, virtually any size hole can be cut into the pipe.
The tractability of Hot Tapping Pipelines is one of the major reasons why large numbers of people are choosing it as the primary way of working on pipelines. It can be done manually or automatically, and hot tapping can be done on both surface pipelines and subsea pipelines. There are different power options are available, including hydraulic and pneumatic power systems. Drill lengths can be of different sizes, and it's possible to bore a hole anywhere from half an inch to several feet in diameter. If necessary, even larger holes can be cut in pipes. This technique is known to be an extremely safe and secure method of repairing or adding on to existing pipelines.
Hot Tapping is done on material such as carbon steel, stainless steel, cement lined pipe, fiberglass, or plastic pipes. These materials can easily be connected to new sections of pipe. However, hot tapping can also be done on pipes made out of materials that can't be easily welded or sealed, including transite, cast iron, and carbon steel.
