Understanding 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. By and large, with hot tapping, you will be able to avoid much of the costly and potentially dangerous hazards to the environment while at the same time guaranteeing the continued use of these systems. The following is a look at some of the basic facts that you need to know about hot tapping.
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. 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. 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. 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. 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.
