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. 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. Read on for more on hot tapping as discussed below.
Basically, when it comes to pressurized tapping as well known as hot tapping, this is the installation of connections to plumbing systems and lines without breaking the use of the systems. By and large, when it is looked at in the welding concept in strictness, it is the process that allows for the welding onto any equipment that is already in use.
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. 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. 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. As such, you need to ensure that the wall has a thickness that is sufficient enough to prevent 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.
