What pipe freezing is all about?

There are hundreds of industrial applications where pipelines play a crucial in keeping the processes running and active. Any downtime in the pipeline flow may result in huge monetary loss. For example, there is always a scope for maintenance work for which a specific time slot is allocated. The most typical way to carry out any kind of work on a live pipe is to stop the flow and then do the required work in that time period. But today’s competitive industrial environment demands for always up time and zero breakdown. But still accidents never come announced. So here comes the need of a technology that allows engineers to do their regular job on a live pipeline without hindering the running flow in the pipe.

One such process is Pipe Freezing which is defined as an intrusive, controlled method of separating a section of pipe, by solidifying the pipe contents to form a secure ice plug which in turn holds the liquid flow whilst a maintenance work is carried out. The best thing about pipe freezing process is that even a big job can be carried out without causing much disturbance to regular activities at the premises.

During the process, a jacket is fitted around the pipe section to be freeze. There after liquid nitrogen is introduced into the jacket to freeze the contents of the pipe. This process is found to be very effective in industries where shutting down the line even for few minutes can result in severe losses.

Hot Tapping – Playing a vital in oil exploration industry

In today’s digital environment, technology plays a vital role and makes our lives easy. Recently I came to know about hot tapping technology which is used to manage high pressure lines. With the use of this technology, engineers can easily carry out maintenance work on high-pressure liquid or gas pipes without interrupting the flow. Today, this technology is playing a great role by saving lives of hundreds of people working in the industry by allowing easy management of these lines. 

One of my friends works at an oil rig and he told me about each and every aspect of hot tapping and hot tap connection. It is basically a process in which a live pipe connection is cut without having to turn off of material through it. As we know working on high-pressure lines pose greater risks to worker’s lives, this method has proven to be safe and trustworthy. In addition, there won’t be any kind of interruption to the material passing through; it doesn’t hamper the ongoing work. 

Operations like deep water oil and gas exploration are perfect for hot tapping procedures considering the complexity of the work involved. It is not only useful in repairing lines, but also helpful in blow-outs and other malfunctions. There are numerous cases in the past where this technology played a great role in managing the things greatly.

Carry out maintenance work on running pipelines with pipeline isolation

There are numerous cases when the situations demand for pipeline shutdown such as regular maintenance work or any unexpected accident. People start fretting as soon as the line stops and it hampers lots of activities in turn. If that is the case with you, you can analyze the loss it could do to your operations. In addition, your precious time gets wasted on managing things in another way.

In such cases, pipeline isolation emerges out as a great option. This is done by linestopping or pipefreezing. This is a technical process of acquiring the pipeline isolation in a live pipe, so that you don’t have to stop the operations. In other words, you can continue with your maintenance work without any hassles or loss of time while your operations continue as usual. 

The best part of pipefreezing is that it causes zero disruption to running services and nothing gets wasted at all. In addition, this process can be carried out on almost all the pipelines and materials such as iron, steel, concrete, stainless steel etc. Due to its high usability, this is being used on large basis across many industries. 

Though there are many options available other than this - Stopple, shrink fitting, under pressure drilling and a lot more. Typically one particular process in chosen depending on the situation and the industry. All you need to do is to ensure that you are dealing with a prominent and experienced company that will not allow your work to suffer.

What does hot tapping mean?

Hot tapping is also commonly referred to as pressure tapping. It is a way by which you connect to the present pipelines or the containers without the requirement to vacate the section of the connected pipe or the vessel. This means that you can work on the line without the need to shut down the complete system. This process can be really done on the pipes that are carrying the water, sewage, natural gas, steam, chemicals and even the petroleum products.

This process can be done on any of the pipes without the need for any particular material. This operation can be performed on the offshore platforms, gas production plants and even in the refineries and even in any other pace where a pressurized tubular system is present.

This is the first step in the hot tapping which is used to make the hole saw so as to make a hole in the pipe where a plugging lead is put inside. It also permits the pressure to be limited, vented and it can even be removed from the live system.

It offers several benefits like it permits varied operations as the pressure is just contained. The work can be performed on that section of the pipe without the need to shut down any other operations.

Hot tapping - the lifeline of oil & gas industry!

Oil & gas industry has seen the growth that only a handful of industries have seen. Every day new pipelines, new oil & gas connections are added to new places, to new customers. The industry players have also learnt new ways to overcome the common problems such as the difficult that would arise when a pipeline would start leading and stopping the entire pipeline wouldn’t be a feasible idea. Hot tapping services have become the standard norm to handle such mishaps.

Under hot tapping, the maintenance team would ensure that the pipeline maintenance and repairs is done in the minimal time and without having to restore to options like complete shutdown. How things would have been had hot tapping not been around for the industry that regularly needs assistance for the damaged, leaked pipelines.

Apart from hot tapping, companies have other options such as Pipe Freezing, Line Stopping, and Shrink Fitting. Please note that hot tapping is also known in the market as Under Pressure Drilling. Depending on the nature of the pipeline, content, and damage caused, maintenance team would choose the most-appropriate method for the repairs.

The good thing is that there are many companies out there in the marketplace that offer these services. So, it should not take you long to find the one that best serves your business interests.

How the systems of hot tapping function?

Hot tapping is a procedure that is also known as pressure tapping and it is a means to connect the present pipelines or any kind of vessel. In this form there is no need to empty out the connected section of the pipe or even the vessel for that matter. This would mean that the work can be completed on the line without the need to shut down the whole system.

This process can be carried over on to the sewage, natural gas, steam, chemicals, petroleum products, and even any other kind of products. This process can also be completed on the offshore platforms, gas production plants, refineries etc.

The first step in the line stopping process is to use a whole saw and to make that hole in the pipe you need to insert a plugging head. This helps in getting the pressure to be contained, vented, and even removed out of the live system.

Hot tapping services give a lot of diverse benefits and firstly it permits to have multiple operations till the time the pressure is totally contained. The work can be done in such a way where the operations need not be stopped in the middle of it. If you’re in need of adding such a pipe to your operations, then you can do that by getting in touch with the service provider.

Hot Tapping – reasons you can’t do without hot tapping

Hot Tapping is not a new concept; but, still there is a large number of gas, water, and chemical companies in the UK that still have no idea about how beneficial hot tapping could be, for them, for their pipes.

Hot Tapping is an innovative method to repair a pipe that is carrying gas, water, or chemicals at high temperatures and under pressure. When complete shutdown doesn’t make sense, Hot Tapping comes into the scene!

With specialised tools, the affected part is repaired by creating a temporary by-pass so that business customers do not have to suffer. Hot Tapping can be performed on almost all sorts of pipes, such as iron pipes, stainless steel pipes, concrete pipes, etc.

Hot Tapping ensures minimal disruption to the work, minimal loss of content, and time. There is a large number of companies that are into Hot Tapping Service. They can work as your extended team. Or, you can outsource all the repairs & pipeline related work to a selected service-provider.
