What is Hot Tapping
Hot tapping, as well referred to as pressure tapping, is a method of having a connection to a pressurized system, which can be by drilling or cutting, without having the pipe removed from use. With hot tapping, you will be able to prevent costly and some of the potentially hazardous effects to the environment without disrupting the need for continued use of these systems. Read on for more on hot tapping as discussed below.
Generally speaking, when it comes to hot tapping or pressure tapping, this can be said to be strictly that process of having installation of connections to a pipeline and this is done without causing an interruption to the use of these systems. Now, when we look at it in the strict welding concept, hot tapping can be said to be that process that allows for the welding onto any equipment that happens to be in use already.
Hot tapping is generally a technique that is commonly used to make repairs to the parts of a plumbing system that has been exposed to mechanical damages such as corrosion and as well for the need to add branches for the sake of the necessary modifications to these systems. In fact, there are a number of outstanding benefits that come with the performance of such kinds of welding techniques, where there is no removal of the from use, and these come in both the environmental and economic fronts.
If at all you are considering hot tapping as a plumbing solution going forward, you need to know of the fact that there are some risks that come with them so as to take measures to protect against these particular risks. Some of the risks that you need to know of as likely when it comes to hot tapping are such as the risks of unstable decomposition of the products that may be flowing through the plumbing systems, hydrogen cracking and the risk of burn through. The cases of burn through often result from such incidences where the unmelted area there is below the weld pool is weak as not to be able to contain the internal pressure that lies within the piping systems. You therefore need to ensure that the wall’s thickness is one that will be as good and sufficient to contain this and as such reduce the risk of a burn through.
The cases of unstable decomposition of the flowing products often result in rather violent reactions in the event that they are subjected to heat and such intense pressure. In order to protect against such risks of unstable decomposition, you need to therefore take all measures to ensure that the internal temperatures do not go beyond the critical temperatures which are dependent on the kind of material or product that you will have flowing within these plumbing or piping systems.
