Hot tapping is a process which involves making a connection to a live pressurised pipeline system, without the need to shut it down. It allows for pipe modifications, maintenance, or new branches to be added to the existing pipes.
The process usually involves attaching a fitting that includes a valve and tapping machine to an existing pipeline. Then a cutting tool is used to create a hole in the pipe, and a new branch is connected. This is all completed while maintaining pressure.
The process involves high risk as pressurised systems and specialist equipment are worked on. It is important that hot tapping work is carried out by a professional because of this. A professional will have the skills needed to ensure that strict safety procedures and industry standards are adhered to. This is crucial to prevent serious accidents. Attempting to DIY it has a severe risk of injury. Here at Seal Team Systems we can help. We offer hot tapping services across the UK.
The Difference Between Hot and Cold Tapping
If you haven’t heard of hot tapping, you may have heard of cold tapping. However, there’s a major difference between the two processes.
As discussed, hot tapping involves making a connection to a live pressurised pipeline that is still on. Cold tapping involves shutting down and depressurising a pipeline before making a connection to it. It’s done without applying heat or using welding techniques. Instead, this system relies on mechanical fittings to create a pressure tight connection.
Cold Tapping Disadvantages
The process of cold tapping has many possible disadvantages compared to hot tapping services.
Pipeline shutdown: The whole pipe needs to be shut down for the cold tapping method. This can lead to significant disruptions due to increased downtime.
Depressurisation needed: Using this method, each pipe needs to be depressurised and emptied before work can begin. This can be more costly.
Longer process: The process of cold tapping can extend the duration of a project because of the additional steps involved in shutting down, emptying and restarting the pipeline.
More labor needed: Extra laborers will be needed to complete the additional steps required in the process. This will prove more costly.
Benefits of Hot Tapping
In comparison, the process of hot tapping has many benefits. It can be performed on most pipes. It’s also a safe and effective way of carrying out repairs and upgrades whilst your system is still up and running.
System pressure unaffected: It allows for branches to be connected without affecting the pressure and flow of the pipe system. This allows normal operations to continue whilst work is being completed.
Cost saving: In the long run, this process can have many cost saving benefits. Avoiding system shutdowns helps to reduce the costly impact of downtime. As drainage isn’t required, money will be saved on labor costs too.
Works on a wide range of materials: The process works on various pipe materials such as copper, carbon steel, stainless steel and iron.
No draining required: With other methods of pipe maintenance, it’s normal for the need to drain the entire system before work can begin. It’s done so repairs can be done more efficiently, however it takes a long time and often requires significant financial investment. Hot tapping does not need any drainage to carry out the process effectively, and makes it possible for normal operations to continue whilst the work is being carried out.
Smart Investment: Investing in hot tapping services over other pipe services can lead to the need for less requirement of maintenance, and increased durability, making it a smart investment, saving you money in the long run.
