A hot tap is defined as a drilling machine that is used to cut a hole into an in-service under pressure piping system. This process is done without any service interruption or product leakage.

The typical applications of a hot tap include making a branch connection to begin a bypass and to allow performance of a line stop.

The various components required to perform a hot tap typically comprises of a fitting that is designed to contain a system pressure, where a valve is used to control the new connection along with a drilling or a tapping machine.

Hot tap services permit the clients to modify, maintain, and even repair the pressurized systems with no interruption in between the production. The companies involved in doing these form of businesses provides the highest level of satisfaction to the customers.

The equipment and the service technicians who are involved in doing this form of business are prepared to meet any kind of challenges whether they are emergency, planned, or any kind of routine maintenance activities for the clients. ...

Basically, hot tapping is the process of cutting holes into the pipes, tanks, or any other pressurized container without causing any delay in the function and with no amount of release or loss of the product.

The wall tapping systems allow new kind of tie-ins in the present systems and the insertion of the devices into the flow stream, permanent or temporary bypasses and even at the preparatory stages for the line plugging.

There is another form of tapping known as angle hot tapping which refers to any kind of hot tap where the center part of the tapping nozzle is not perpendicular to the surface that is being tapped. Before you begin with any kind of welding, you need to contact the service department to discuss the extent of angulation and the required need to have a centering device to control the pilot drill. Usually, the companies are equipped to perform the angle taps in various sizes that are off perpendicular and are also into the heel of the short or long radius ells.

The tapping procedure when done on heavy vessels or blind flanges is not a problem as the special issues are addressed with the design of the branch connection.

Other materials that are tapped are cement lined pipe, transite, cast iron, stainless steels, alloys, plastic and fiberglass. Even though these materials are tapped frequently, other information like the thickness and composition of the linings, hardness of the alloys, or the kind of fitting and valve through which the operation will happen be required to ensure that proper equipment is required for the job.
