Also known as pressure tapping, hot tapping is a method of attaching to a pressurized system, either by having them drilled or cutting, while you don’t remove the pipe or tank from being in use. Actually, with hot tapping or pressure tapping, enables you to prevent a lot of the costly and likely harmful environment hazards even as you remain assured of the 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. When looked at in the strict welding concept, it may be considered to be that process that allows for the welding onto equipment that are already in use.
By and large, hot tapping is in most cases used to repair some of the areas that happen to have undergone some damage as a result of mechanical effects like rusting or to introduce branches for modification to the systems in place. For a fact, there are lots and lots of benefits that follow the performance of these kinds of welding techniques where there is no cut on the use of the systems, and these are in the economic aspect and as well on the environmental front as well.
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. Burn through will occur in the event that the area unmelted that so lies below the weld pool happens to be weak as not to be able to contain the internal pressure within the pipes. Therefore, you need to make sure that the wall has a thickness that will be as good enough to sustain the internal pressure there is within the pipes to avoid the risk of burn through.
Instability in decomposition of the flowing products can result in such violent reactions in the event that they are heated under such pressure. For you to ensure that such cases or risks of unstable decomposition of the flowing product within the systems, you need to ensure that you have taken all the necessary precautionary measures are taken so as to ensure that the internal temperatures do not exceed or go beyond the critical temperatures which is often dependent on the product that will be flowing therein.
