Hot tapping is basically a method that allows you attach or connect to a pressurized system like a pipeline or some other pressure vessel, which can be by drilling or cutting, without removing that system 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. Check out the following for more on the facts you need to know of on hot tapping.
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 often employed when it comes to the repairs of the areas that happen to have gotten damaged as a result of effects such as corrosion or to introduce some branches to the systems for modification purposes. And as a matter of fact, there are lots of advantages, economic and environmental, to performing such kinds of welding where you don’t removing the pipes from use.
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. Problems can be experience with hot tapping in such cases as where there is a burn through, cases of unstable decomposition of the product that is flowing through and as well the risk of hydrogen cracking. 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. As such, you need to ensure that the wall has a thickness that is sufficient enough to prevent the risk of a burn through.
Unstable decomposition of the flowing products often leads to violent reactions when there is a heating process under such intense pressures. 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.
